Unit description

Unit deﬁnitions

According to EU directives, the

units are deﬁned as:

“Gas hot air heaters without

draught diverters with a fan

upstream of the heat exchanger”.

The units are fully automatic,

direct-ﬁred hot air heaters for wall

and ceiling mounting.

They can be ﬁred with natural gas

or LPG.

The units are used for constant or

temporary heating of closed and

open rooms, e.g. in:

Halls, workshops, greenhouses,

storage rooms, etc.

Unit classiﬁcation

The units are classiﬁed by the

European standards EN 437 and

EN 1020 according to:

Gas category:

Classiﬁcation of the types of

gases with which the units can be

operated.

For Germany DE II2ELL3B/P

Type of gas:

The burner can be operated with

gases of the second family (natural

gas groups H and L) and with

gases of the third family (butane

and propane).

Type of gas appliance:

Classiﬁcation according to options

for discharge of combustion

products and supply of combustion

air. (Room sealed/non-roomsealed)

For further information, see

chapter “Installation of chimney

duct and combustion air supply

pipe”.

Unit design

The outside housing of the units

is made of coated sheet steel for a

long useful life.

The outlet air grille(s) is/are

located at the front.

To ensure optimal hot air

distribution in the installation

room, the horizontal ﬁns of the

air outlet grille can be adjusted

manually.

The circulation air fan(s) with

outlet grille, exhaust fume

discharge and combustion

air supply connections, gas

connections, electric cable lead-

throughs and plug connector for

mains connection are located at

the rear of the unit. Located on the

right side behind the inspection

door are the components

necessary for control and safety

such as

- the electrical circuit with wiring

- the control electronics

- the gas valve

- the modulating gas burner

The combustion chamber with

heat exchanger is located inside

the unit, directly in the circulation

air ﬂow.

The combustion chamber is made

completely of Inox stainless steel

AISI 430.

Inox stainless steel AISI 441 is used

for the heat exchanger for higher

resistance to corrosion due to

moist vapours.

The special shape and large surface

of the combustion chamber and

heat exchanger ensure high

efﬁciency and a long service life.

The gas burner is also made

completely of specially machined

stainless steel.

Function of the units

GPM series modulating gas

wall heaters were developed for

heating rooms in industrial and

commercial premises.

The electronic control of the units

continuously regulates the heat

output between minimum and

maximum depending on the actual

heat demand.

Efﬁciencies of up to 94% can be

achieved with the premixing and

modulating technology.

The nominal heat output of the

REMKO GPM series is between

11.8 and 71.5 kW.

They essentially consist of the

combustion chamber with heat

exchanger and circulation air

fan(s).

The ambient air is sucked in by

the fan(s) and ﬂows efﬁciently

via the burner chamber with heat

exchanger.

The combustion chamber is heated

by the gas burner and heats the

passing ﬂow of air.

The air heated in this way is blown

out the front of the unit via an

adjustable air outlet grille.

Correct operation of the unit is

only possible with a connected

temperature control, e.g. ATR-6

(accessory).

The units are not suitable for

domestic heating or similar.

NOTE

■

Operation of the safety

thermostat and associated

interlock of the safety

thermostat (STB).

The unit cannot be restarted

without manual reset

■

Damage to electric cables

Safety thermostat(s)

Each fan in the units has a safety

thermostat (STB) for manual reset.

Operation of the safety thermostat

triggers a safety shutdown.

The thermostat is arranged in

the area of the heat exchanger in

order to monitor the temperature

at its outlet.

Blocking of the unit caused by

operation of the safety thermostat

is indicated as fault F2 at the

temperature control.

Air/gas premixture

The units are provided with a

burner with complete air/gas

premixture.

Mixture takes place in the burner

motor fan.

The air sucked in by the fan ﬂ ows

through the Venturi tube, where a

vacuum is produced, which draws

the gas.

This produces a constant air/gas

mixture. The ratio of air and gas

pressure is 1:1.

This value can be changed with

the offset regulating screw located

on the gas valve.

The gas volume is already adjusted

on delivery of the units and the

screw is sealed.

Fine adjustment can be made

with the adjusting screw on the

Venturi tube. This screw regulates

the maximum gas ﬂ ow rate and

accordingly determines the carbon

dioxide (CO2) content of the

exhaust gases.

The screw is not sealed so as to

allow the hot air heater to be

changed to a different type of gas

if necessary.

NOTE:

For offset and CO2 adjustment.

The control board of the units

controls the burner motor speed

with DC current depending on the

room heat demand.

The air and accordingly the gas

ﬂ ow rate changes with changing

speed.

The minimum and maximum fan

speeds are two values that cannot

be changed.

Fans

The circulation air fans are

switched on by the control board

time-controlled, whereby time

control starts when the main

burner is switched on.

The delayed switch on prevents

cold air from being blown into the

room.

Switching off the unit

If there is no more heat demand

(room temperature above the set

value), the control board switches

off the burner.

The burner fan continues to run

for a preset time in order to cool

the combustion chamber.

The circulation air fan (possibly

also more than one) also continues

to run time-controlled until the

heat exchanger has cooled down.

If there is a renewed heat demand

during the after-running phase,

the control board will wait for the

fans to switch off and only then

perform a reset and begin with a

new cycle.

IMPORTANT INFORMATION!

Interrupting the power supply

during burner operation or the

residual heat removal phase must

be avoided as a lack of cooling of

the heat exchanger can lead to

considerable damage.

its components

ATTENTION

Before resetting a safety

device, the cause of its

operation must be located and

eliminated.

NOTE

Safety devices must not be

overridden or blocked during

operation of the unit.

REMKO GPM

The units offer the beneﬁt of a

modulating mode of operation,

i.e. the produced heat output and

accordingly the gas ﬂow rate (fuel

consumption) vary depending on

the heat demand.

With a reduced room heat

demand, the hot air heater

consumes less fuel, whereby its

efﬁciency is increased up to 94%.

Intrinsic safety

An increase in efﬁciency at

minimum output is achieved by

the use of a modern air/gas mixing

technology and simultaneous

regulation of the combustion air

and gas ﬂow rate.

This technology increases the

safety of the unit as the gas valve

supplies the fuel depending on

the air ﬂow rate according to its

factory setting.

In contrast to an atmospheric

burner, the CO2 content remains

the same over the entire control

range of the units and allows

an increase in efﬁciency with a

reduced heat output.

If there is no combustion air, the

valve does not release any gas.

With a reduction of combustion

air, the gas valve automatically

reduces the gas volume and keeps

the combustion parameters at an

optimal level.

Minimal pollutant emissions

The premixing burner allows in

conjunction with the air/gas valve

“clean” combustion with very low

pollutant emissions.

EfﬁciencyOperating cycle

Burner operation

The heat demand for starting the

burner takes place via the set value

of the room temperature sensor in

the temperature control ATR-6.

For units both with and without

temperature control, the burner is

only started when the contact 7+9

on the terminal strip M1 is closed.

On receiving a heat demand,

the control board ﬁrst starts the

burner fan so that the combustion

chamber is pre-aerated for a

certain time.

After pre-aeration, the control

board activates the ﬂame

monitoring device ACF for igniting

the burner by energising the gas

solenoid valve EV1 and EVP, which

supplies the ignition gas burner.

In this way, the gas burner is

started.

The ignition monitoring electrode

monitors correct ignition of the

ignition gas burner.

When this operating condition is

detected, the control device of

the main gas valve EV2 opens to

supply the actual main gas burner.

After a certain time, while both

burners (ignition and main gas

burners) are operating at the

same time, the control board de-

energises the solenoid valve EVP,

whereupon the ignition burner

extinguishes.

Flame monitoring for supervision

of the main gas burner is

continued by the monitoring

electrode.

The start program switches on the

main gas burner with an average

heat throughput of about 70%.

After about 30 seconds, the

burner starts to modulate the gas

ﬂow rate and ﬁnally reaches the

adjusted gas ﬂow rate.

During operation, the control

board regulates the gas ﬂow rate

of the burner proportional to the

circulation air temperature, which

is measured by the NTC1 sensor at

the rear of the unit.

Modulation

The gas wall heaters are units

with gas burner modulation which

makes operation with diverse

outputs between minimum and

maximum possible. The maximum

output serves to quickly raise the

room temperature when the units

are switched on.

With the modulation feature

by contrast, the required room

temperature can be maintained

at a constant level with constant

variation of the heat output

appropriate to actual demand.

With this automatic adjustment

of the heat output to the

room conditions, the physical

phenomena of layer formation (the

tendency of heat to rise) can be

restricted due to the reduction of

the air supply temperature.

The temperature differences per

metre are below 0.5°C.

When the units operate with a low

heat output, efﬁ ciency above 94%

is achieved.

These results can only be achieved

by precise monitoring of the

climatic room conditions and

optimal control of the units.

For dimensioning heating centres

with hot air heaters, it is important

to observe the number of hourly

air exchanges.

In this respect, the following

should be noted:

Wall gas heaters should generally

be dimensioned so that the air

ﬂ ow rate ensures a minimum of

two air exchanges per hour, even

if this is unnecessary for the heat

output.

The units have a room temperature

sensor NTC1 located at the rear

of the unit as standard so that

the temperature of the air sucked

in by the circulation air fans is

monitored.

Modulation takes place depending

on the value measured by this

sensor in a ratio to the value preset

on the microprocessor on the

control board.

Optimisation of the modulation

temperature value must take place

during operation of the system and

depends on the distance of the hot

air heater from the ground and

required temperature conditions.

The wall gas heater is normally

installed at a distance of 2.5 to 4 m

from the ground.

This ensures that the required

comfort temperature is reached

and maintained, whereby it is

important that the units are

operated at the lowest possible

modulation temperature which

is necessary to maintain these

conditions.

The modulation temperature (REG

SAN value) is factory set at 21°C.

This value allows an average

installation range between 3 and

5 metres at room temperatures

between 17 and 19°C

(see graph below).

Room correction

For this function, use of the

temperature control ATR.6 is

necessary.

A type of function is described

in the following that enables

maximum energy efﬁciency to

be achieved by the hot air heater

assisted by the control electronics

and temperature control.

In order to activate the ambient

correction function, the parameter

[C1]

param k 11 must be set to 1.

The purpose of the room

correction function is to ensure

rapid heating at the beginning and

subsequently maintain the room

temperature at a constant level.

In this way, not only can layer

formation in the room air be

reduced, but also the fuel demand

reduced in particular.

The two correction reference

values are the temperature

measured by the sensor NTC2

(in the temperature control) and

the circulation air temperature

measured by the sensor NTC1 (at

the unit).

To activate the function, set the

parameter

param k 17 to 1.

When the room temperature

approaches the setpoint value,

the modulation temperature is

changed linearly based on the two

parameters A16 and A24.

This makes it possible to operate

the unit on heat demand

at maximum output and to

quickly reach the preset room

temperature.

The heat output is subsequently

reduced which increases the

efﬁciency of the unit and the room

is heated with less hot air.

This enables the layer formation in

the room air and simultaneously

the heat loss to be reduced.

The units are supplied with the

following factory settings:

Modulation temperature:

„REG SAN“ 22°C

Neutral correction range:

A24 2°C

Correction coefﬁcient:

A16 2

The parameter A24 determines

the range within which the

room temperature is corrected.

The parameter A16 offers the

possibility to increase the efﬁciency

of the temperature reduction

to the setpoint “REG SAN” as

shown on the graph. At the

standard setting, the modulation

temperature on reaching the room

temperature corresponds to:

„REG SAN“ =

24°C-(2°C x 2.5) = 19°C

The correction is independent of

the set room temperature.

The graph shows the room

temperatures [ST2] in relation

to the installation height of the

units „REG SAN“ during the initial

heating phase.

To deactivate the correction, set

the parameter [C1]

param k 11 to

When deactivating the correction,

the value “REG SAN” must be

correctly regulated in order to

avoid the following conditions:

- „REG SAN“ adjusted too high:

Strong layer formation with

high heat loss in roof area and

increased energy demand as a

consequence.

„REG SAN“ adjusted too low:

Time to reach the required room

temperature too long.

With correction deactivated, adjust

“REG SAN” so that the value is

higher than ST2 by the difference

in metres between the room and

modulation sensor multiplied by

0.4/0.5°C.

To change the modulation value

“REG SAN” on the temperature

control and to change all speciﬁed

values, see further back in the

manual.

The faults indicated and stored by

the control board (interlocks) have

the following causes:

- Fault of the ﬂ ame monitoring

device due to burner ignition

failure; the control board

makes several automatic reset

attempts prior to signalling

the fault.

- Operation of the safety

thermostat.

If the temperature detected

by the thermostat is too high,

the same operates and blocks

operation of the unit.

- Burner fan faulty; the

combustion air fan is faulty or

the signal to the control board

is outside the tolerance range

with respect to the requested

speed.

- NTC1 sensor faulty or not

connected – the sensor value

is outside the measuring

range.

- Control board fault due

to constant and repeated

unsuccessful ignition attempts

of the unit for a predeﬁ ned

period.

With this fault, the fault

signalling LED located on the

control board also lights up.

- The control board sent the

starting signal to the ﬂ ame

monitoring device, but did

not receive the started signal;

it is possible that the ﬂ ame

monitoring device is faulty.

The faults F1 and F2 are caused by

safety devices and are therefore

permanent.

The fault still remains after

switching the mains off and

on again and can only be reset

manually.

The faults F3, F6 and F8 must be

reset manually or by switching the

mains off and on again.

In contrast, fault F4 is self-

resetting:

After clearing the fault, reset takes

place automatically.

The safety information on the

previous pages must be strictly

observed.

In exceptional circumstances, the

units can also be operated brieﬂ y

without temperature control.

For this purpose, the jumper on

terminals 7+9 on the terminal

strip M1 in the switchbox must be

removed and a switching device

(e.g. thermostat) connected.

The CR switch on the control

board must be set to OFF (see Fig.

on page 14) and the connector CN

with resistor (see Fig. on page 26)

plugged in.

For this mode, it is neces-

sary to connect at least one

switching device, e.g. room

thermostat in order to be able

to switch the burner on and

off.

NOTE

All information relating to the unit

and faults are now indicated via

LED indicators on the front of the

unit.

The green LED lights up to indicate

that the unit is connected to the

mains.

The red LED lights up to indicate a

fault on the unit.

The cause of the fault can

immediately be identiﬁ ed by the

different ﬂ ashing/illuminating

states of the red LED:

- LED shows a steady light

- LED ﬂ ashes twice rapidly

- LED ﬂ ashes three times

rapidly

- LED ﬂ ashes four times rapidly

- LED ﬂ ashes constantly

- Red and green LED ﬂ ash

REMKO GPM

The following instructions for

installation adjustment of the

units are intended exclusively for

authorised specialists.

The following safety information

must be observed.

General information

The units can normally be installed

directly in the room to be heated.

Installation of the units must

always take place in compliance

with the building regulations

(LBO) and the Ordinance on

Firing Installations (FeuVO) of the

respective federal state.

The First Ordinance on the

implementation of the Federal

Immission Control Act (1st

BImSchG) and the subsequently

issued statutory requirements of

the Ordinance on Small Firing

Installations (1st BImSchV) must

also be taken into account.

The installation of hot air heaters

operating with gas burners is

forbidden in the following rooms:

■

in public functional rooms or

in rooms with a person density

from 0.4 per square metre

■

in rooms in which gas or dust

can form due to the processes

occurring in these rooms or

through materials stored in

these rooms

Installation instructions

The minimum height and distances

of the hot air heater from walls

and ﬂoors are shown in the dia-

gram below.

The minimum distances are the di-

stances necessary for maintenance.

All dimensions are in mm. The

height [2500 mm] corresponds

to the minimum height for “sus-

pended units” as speciﬁed in the

applicable directives.

Two different types of brackets are

available as accessories for instal-

lation.

Fixed and hinged.

The order numbers for the wall

bracket (hinged type) are:

4002500

To avoid dangerously high

voltages be reached, the distance

between the outer surface of

the unit and chimney pipe and

any possibly stored ﬂammable

material at a distance to the ﬂoor

of 2.5 m or above must under no

circumstances be below 1.5 m.

Units with gas burner for gas

with a density above 0.8 (LPG,

propane, butane) may only be

installed in rooms in which the

ﬂoor is not below ground level.

Ventilation openings

are used must have one or several

permanent openings (windows or

doors).

These openings must be provided

at the following points:

- directly below the ceiling for

gases with a density below 0.8;

- directly above the ﬂoor for

gases with a density above or

equal to 0.8.

Openings in outside walls must be

provided externally. The installed

heat output is decisive for the

cross-sectional sizes.

Installation

We reserve the right to make changes to dimensions and design in the interest of technological advances.

Hinged wall bracket

Instructions for ﬁ tting the hinged

brackets are supplied in the

packaging.

The use of hinged brackets is

pencil.

- Securely fasten the wall brackets

using suitable dowels and bolts

size M10 or larger.

- Fit both pairs of brackets as

shown in the diagram using the

supplied material.

- When ﬁ tting the brackets, lock

the nuts by using a lock ring

between the brackets and nuts.

- Position the unit on the brackets

so that the holes in the unit

coincide with those in the

brackets, whereby the tips of the

brackets must be ﬂ ush with the

front of the unit (except for GPM

75).

- Fasten the units with the M8

bolts provided, whereby a lock

ring must be inserted between

the bolt and bracket.

EDP No: 228760

ATTENTION

We reserve the right to make changes to dimensions and design in the interest of technological advances.

The brackets must be screwed

stress-free to the unit and wall.

NOTE

Ensure that the type of dowels

and size of the bolts are

suitable for the type of wall

Ceiling suspension

A ceiling installation set with horizontal air outlet is available as an

accessory for suspending the units using eyebolts. EDP No: 228765

Vertical air ﬂow

Suspension of the units using

eyebolts with the air ﬂow directed

downwards (installation with

vertical air ﬂow).

A ceiling installation set with

vertical air outlet is available as an

accessory for this purpose.

It consists of eyebolts with special

fastener and additional fan

thermostats.

EDP No: 228766 to GPM 35

EDP No: 228767 from GPM 55

We reserve the right to make changes to dimensions and design in the interest of technological advances.

Additional thermostat for

fan monitoring

The units operate in a closed

combustion system.

The fan is located upstream of the

heat exchanger.

The chimney duct and combustion

air supply must be planned and

executed in compliance with the

respective local regulations.

For outside wall installations, the

local master chimney sweep must

previously be consulted.

The various types of installation

are classiﬁed according to the

European standard EN 1020 and

DVGW-TRGI Directive 2008 and in

the factory supplied variant is part

of the EC approval.

The units are classiﬁed for the

following individual variants:

B23/C13/C33/C43/C53/C63

The chimney and air supply pipes

can be installed in different ways.

For example: Gas appliance type

The combustion system is not tight

with respect to the environment in

which it is installed.

The combustion air is extracted

directly from the installation room.

This variant may only be installed

in rooms having at least one

door leading to the outside or

one window that can be opened

and having a cubic capacity of

minimum 4 m

per kW total

nominal heat output of the unit or

a combustion air opening leading

to the outside of minimum 150

or two openings each having

a minimum free cross-section of 75

Chimney connection

For example: Gas appliance type C:

The combustion system is tight

with respect to the environment in

which it is installed.

The combustion air is supplied

from the outside.

The units must only be operated

with suitable chimney pipes.

The components available as

accessories from the factory

comply with all requirements as

standard.

Condensation

If necessary, the chimney pipes

must be insulated to prevent the

formation of condensation in the

same.

The exhaust gas temperature at

minimum heat output corresponds

approximately to the condensation

temperature.

For pipe lengths above 5 m

indoors and 3 m outdoors,

condensation must be prevented

as follows:

■

By cladding the chimney pipes

■

By using condensate drains

from where the collected

condensation can be removed

from the chimney pipe.

Note:

Suitable condensate drains are

available as accessories.

These can be used for both

horizontal and vertical pipes.

Guide for selection

If the chimney end piece is not

connected directly to the unit,

but longer distances have to

be covered, it must be ensured

appropriate to the total length and

geometry of the chimney duct that

the end pieces and extensions as

well as the bends have the correct

diameter.

After determining the chimney

duct, the pressure loss for

the respective unit must be

determined.

The pressure loss varies for each

unit as the exhaust ﬂ ow rate is

output-dependent.

Add up the determined pressure

losses of the individual chimney

components and ensure that the

total is not above the pressure

available for the type of unit to be

used.

If a combustion air supply pipe

exists, the pressure losses must

be added to those of the chimney

pipe.

If the total pressure losses are

above the available unit pressure,

chimney and fresh air pipes with a

larger diameter must be used.

In this case, calculation must be

repeated.

The maximum possible pipe

lengths between the unit and end

piece are shown in the tables.

When using chimney bends,

it is necessary to take the

corresponding pressure losses into

account.

NOTE

Exceeding the permissible

pressure losses in the pipes

will reduce the heat output

and affect the safe operation

of the units.

ATTENTION

Installation must only be car-

ried out by authorised specia-

lists.

Pressure loss examples:

A 90° bend with Ø 80

corresponds to a 1.7 m straight

pipe length

A 45° bend with Ø 80

corresponds to a 0.8 m straight

pipe length

A 90° bend with Ø 100

corresponds to a 1.9 m straight

pipe length

A 45° bend with Ø 100

corresponds to a 0.9 m straight

pipe length

Examples of chimney pipe and

combustion air pipe arrangements

are shown on the following pages.

The units are classiﬁ ed for the

following individual installation

B23/C13/C33/C43/C53/C63

Installation examples

Gas appliance type B23

Non-roomsealed combustion

system

The combustion system is not tight

with respect to the environment

in which it is installed. The

combustion air is extracted directly

from the installation room.

There are two options for

installation of the chimney ducting:

a) with the aid of a horizontal

pipe (outside wall installation)

straight through the outside wall

b) if the roof is simultaneously the

ceiling, with a vertical pipe via

the roof.

With this installation option,

adequate ventilation of the

installation room must be ensured

in order to provide a correct

combustion air supply.

This takes place by means of

openings in the room walls.

The dimensions and characteristics

deﬁned in applicable standards

must be observed.

In particular, DVGW-TRGI 2008

Section 5.2.2. and TRF Section

7.2.2. must be observed.

Arrangement of factory supplied gas components

must be installed by the

installation company

Installation of the gas connection

must only take place by authorised

specialists (approved by the gas

supply company) in compliance

with the regulations applicable to

the respective type of gas.

The cross-section of the cables

must be dimensioned according

to the installed load of the unit,

total line resistance and gas supply

pressure.

The necessary gas supply pressure

(depending on the particular type

of gas) must be ensured locally.

Depending on the capacity of the

unit, the necessary gas volume

and gas pressure must be available

constantly during operation.

Connection of the unit takes place

via a R 3/4“ or R 1“ connection

with external thread.

The gas supply pipe must be

installed stress and vibration-free

using suitable, detachable unions.

The components prescribed in

the pertinent gas directives and

necessary components in the gas

pipe locally must be installed by a

qualiﬁed installation company.

Gas pressure reducers, shut-off

devices, etc., are not included in

the factory delivery and must be

provided locally.

The installation of a gas ﬁlter

without pressure regulator is also

recommended as the area of the

standard ﬁlter installed above the

gas valve is limited.

The applicable standards allow

within rooms or heating rooms a

maximum pressure of 60 mbar;

higher pressures must be reduced

prior to admission into the heating

room or room in which the unit is

installed.

Before using the unit for the ﬁrst

time, the gas supply pipe must be

thoroughly cleaned and vented by

suitable means.

It must be ensured that the unit

is connected gas-tight to the gas

supply pipe.

All screwed connections of the unit

and gas pipe must be checked for

tightness.

If leak detection sprays are used,

these must comply with DIN

30657 (corrosion-free).

We reserve the right to make changes to dimensions and design in the interest of technological advances.

ATTENTION

Installation of the gas system

and supply pipes must only

be carried out by authorised

specialists.

Commissioning must be carried

out only by an authorised

installation company or factory

customer service engineers.

The following steps must be

carried out prior to commissioning:

1. Check all connections and

unions of the unit and gas

connection for tightness.

2. Check all accessible electrical

screw-type and plug connectors.

3. Check the electrical connection

for polarity and the mains

supply (230V/50Hz).

4. Check that the unit is

professionally connected to an

effective earthing system in

accordance with the applicable

safety standards.

Only when this is provided,

is electrical safety and reliable

function of the unit ensured.

5. Check that the electronic

temperature control ATR-6 is

correctly connected.

The units are delivered preset

at the factory depending on the

required type of gas.

The complete unit must be

checked for correct functioning

and tightness of all gas

connections.

ATTENTION

Gas pipes must never be

used for earthing electrical

equipment!

Commissioning

It must be ensured that a gas

supply pressure conforming to

standards is constantly available

depending on the type of gas

available locally.

The supplied gas must correspond

to the gas category set on the unit.

The procedure for commissioning

the burner is as follows:

1. Loosen the screwed cap in the

pressure measuring connection

of the burner.

Do not unscrew fully!

2. Connect a suitable pressure

gauge, e.g. U-tube manometer,

minimum resolution 0.1 mbar.

3. Open the gas shut-off devices.

4. Switch on the main/emergency

switch.

5. Adjust the room temperature

setting on the temperature

control ATR-6 to a higher

value than the existing room

temperature.

6. Set the mode selector switch

on the front of the unit to the

position “Heat”.

7. Set the temperature control to

“MANUAL MODE”.

8. Check that the heating symbol

lights up on the temperature

control display.

9. Adjust the heat demand

temperature higher than the

temperature measured by the

room thermostat or temperature

control.

A small ﬂ ame lighting up on the

display shows that the burner is

switched on.

It is possible that the ignition

burner does not ignite ﬁ rst time

due to the presence of air in the

gas pipe, so that the unit generates

a fault.

The unit must be reset and the

starting procedure repeated.

Only authorised specialists

may make adjustments and

carry out maintenance work on

the unit and gas burner.

ATTENTION

Combustion analysis

Start the burner and after

switching on the fan bring the

burner to “maximum output” by

pressing and holding the reset

button on the front of the unit for

2 to 3 seconds.

Operation at maximum output is

indicated by the green LED on the

front of the unit ﬂ ashing once.

Ensure that the gas pressure

upstream of the gas valve

corresponds to the prescribed

value, otherwise regulate.

After about two minutes, connect

a gas analyser to the chimney pipe

and read off the CO2 value.

Compare this value with the values

in the “Gas settings“ table for the

type of gas used.

REMKO GPM

If the value is outside the speciﬁed

range, readjust with the CO2

regulating screw on the Venturi

tube.

- When the screw is tightened,

the gas ﬂow rate decreases as

does the CO2 value.

- The CO2 value increases when

the screw is unscrewed.

Subsequently set the burner to

“minimum output” by pressing

and holding the rest button again

for 2 to 3 seconds.

Operation at “minimum output” is

indicated by the green LED rapidly

ﬂashing twice.

Wait until the minimum output

at the burner has stabilised and

check that the CO2 value is equal

to or slightly below the CO2 value

at the maximum ﬂow rate ( up to

-0.3%).

A deviating value can be corrected

with the offset screw.

To make changes to values,

remove the metal plug and turn

the regulating screw:

- the CO2 value decreases when

the screw is unscrewed,

- the CO2 value increases when

the screw is tightened.

After making any adjustments with

the offset regulating screw, the

CO2 value at maximum output

must be rechecked by carrying out

the above described steps.

After carrying out these steps,

set the burner to “normal” mode

by pressing and holding the reset

button again for 2 to 3 seconds.

This mode is indicated by the

green LED showing a steady light.

If the unit is not set to

“normal mode“, the control

board will automatically reset

the unit after 20 minutes.

Venturi tube

If the unit is not used for a

prolonged period, the gas

valves must be closed and

the main switch of the unit

switched off.

ATTENTION

The entrance of the Venturi

tube must under no

circumstances be covered by

the hands or other objects.

This can lead to ﬂashback of

the premixing burner.

The unit performs a cooling

cycle in any event before the

fans are switched off.

NOTE

We reserve the right to make changes to dimensions and design in the interest of technological advances.

After carrying out all steps for

commissioning, the user must be

instructed in the operation of the

unit and its control.

If the unit is not set to “normal”

mode, the control board will

automatically reset the unit after

20 minutes.

This also occurs if the power

supply to the unit is disconnected

and then reconnected.

Check the electrodes for correct

seating (see diagram).

It is important that the monitoring

electrode [IO] is located tangential

to the ignition burner head and is

not located within the same.

The ignition electrode [Z] must

discharge towards the outside

edge of the ignition burner at

an adequate distance to the

monitoring electrode.

2) Checking the chimney and

supply air pipes

Visually inspect all pipes and

connecting pieces.

Any dirt deposits that have

accumulated on the end piece

of the supply air pipe must be

removed.

3) Checking and cleaning the

Venturi tube

Remove dirt deposits at the

entrance of the Venturi tube with a

brush or other suitable implement.

Ensure that no dirt falls in to the

Venturi tube.

4) Checking the gas supply

pressure

Ensure that the pressure upstream

of the gas valve corresponds to the

value prescribed for the respective

type of gas.

This check must be carried out

with the unit switched on at

maximum output.

5) Checking the ﬂ ame monitoring

device

With the unit in heating mode,

close the gas valve and ensure that

fault F1 is indicated. Open the gas

valve again, reset and wait for the

unit to restart.

6) Checking the safety

thermostat(s)

This check must be carried out

with the unit operating in heating

mode.

- Heat the thermostat sensor using

a hot air gun or similar until fault

F2 is indicated.

- Allow the thermostat sensor(s) to

cool down and reset the unit.

- This check must be carried out on

all thermostats in the unit.

Maintenance

2-3 mm

In order to ensure maximum

performance and a long service

life of the units, several checks

must be made once a year and in

any event before the start of the

heating season.

1) Check the condition of the

ignition and monitoring

electrodes as well as that of the

ignition gas burner.

2) Check the condition of the

supply air and chimney pipes as

well as the end pieces.

3) Check the Venturi tube for

clogging.

4) Check the heat exchanger for

fouling.

5) Check the gas pressure

upstream of the gas valve.

6) Check the function of the ﬂ ame

monitoring device.

7) Check the safety thermostat(s).

8) Check the ionisation ﬂ ow (> 2

microamperes)

1) Checking the electrodes

Dismantle the ignition burner

completely and clean the gas

system and gas nozzle with

compressed air.

Check the ceramic coating on the

electrodes for intactness.

Carefully remove any oxide

deposits on the metal part of the

electrodes with a very ﬁ ne emery

cloth.

For steps 1, 2, 3 and 4, the

mains and gas supply to

the unit must always be

interrupted.

Steps 5, 6, 7 and 8 are carried

out with the unit in heating

mode.

NOTE

We reserve the right to make changes to dimensions and design in the interest of technological advances.

REMKO GPM

7) Checking the ionisation ﬂow

Carry out this check using a

tester that is able to measure

microamperes using DC current.

- Disconnect the unit from the

mains supply.

- Disconnect the cable from the

ﬂame monitoring device and

connect it to the negative pole of

the tester.

- Establish a cable connection

between the positive pole of the

tester and the ﬂame monitoring

device.

- Switch on the unit again and

measure the ionisation ﬂow.

The ionisation ﬂow value must be

above 2 microamperes (µA).

Lower values are a sign of a badly

positioned or oxidised electrode.

- Remove the ﬁxing screws for

the cover [A] of the chimney

collection box.

- Using a suitable pipe brush, clean

the entire length of the pipes on

the inside, whereby the dirt must

be swept towards the collection

box as far as possible from where

it can be removed by suction.

- After cleaning the pipes, reﬁt

the cover [A] of the chimney

collection box and check for

tightness.

- After completing the work,

reconnect the unit and carry out

a test run.

Regular cleaning and

maintenance at the latest after

each heating period is a basic

precondition for a long service

life and trouble-free operation

of the units.

NOTE

Adjustments and maintenance

must only be carried out by

authorised specialists.

NOTE

Due to the perfect combustion of

the units, only negligible deposits

normally accumulate here.

Nonetheless, deposits can

accumulate in the heat exchanger

tubes in the course of time. The

usual maintenance intervals must

therefore be observed in any

event.

A symptom of deposits in the heat

exchanger can be a noticeable

decrease in heat output.

The following steps must be

carried out for cleaning the heat

exchanger:

- Allow the unit to cool down and

disconnect it from the mains

supply.

- Open the side door of the unit.

For replacing the gas valve, the

CO2 and if necessary the offset

value must be adjusted.

- Adjust the regulating parameters

of the sensor NTC1 (“REG SAN”

on the temperature control) to

a value that is higher than the

value measured by the sensor

NTC1 (“FLOW VL” on the tem-

perature control).

- Switch on the burner.

The burner will reach maximum

output after about two minutes

after starting.

Connect an exhaust gas analy-

ser and read off the CO2 value.

Compare this value with the “gas

settings” (page 32) for the type of

gas used.

- If the value is outside the spe-

ciﬁed range, it can be corrected

with the CO2 regulating screw

on the Venturi tube.

The gas ﬂow rate and accordingly

the CO2 value decrease when the

screw is tightened.

The CO2 value increases when the

screw is unscrewed.

Subsequently set the burner to

minimum output by adjusting the

REG SAN value to a value that is

lower than the measured tempe-

rature.

- Wait until the minimum out-

put at the burner has stabilised

and check that the CO2 value

is equal to or slightly below the

CO2 value at the maximum ﬂow

rate ( up to -0.3%).

A deviating value can be corrected

with the offset screw.

To make changes to values, un-

screw the metal plug and turn the

regulating screw:

The CO2 value decreases when

the screw is unscrewed.

The CO2 value increases when the

- Elektromagnetische Störungen

- Fehlerhafte Temperaturregelung ATR-6

- Umgebungstemperatur der ATR-6 unter 0°C

Störung des Flammüberwachungs-

geräts wegen nicht erfolgter Zündung

des Brenners; die Steuerplatine

sorgt vor der Meldung der Störung

für eine Serie von automatischen

Entriegelungsversuchen.

Auslösung des Sicherheitsthermos-

taten. Falls die vom Thermostat

erfasste Temperatur zu hoch ist,

löst dieser aus und blockiert den

Betrieb des Gerätes.

Verbrennungsluft-Gebläse ist defekt

oder die Signalmeldung an die

Steuerplatine liegt außerhalb des

Toleranzbereichs hinsichtlich der

verlangten Drehzahl.

NTC1 Fühler defekt oder nicht ange-

schlossen - der Wert des Fühlers

liegt außerhalb des Messbereichs.

Wegen ständiger und wiederholter

erfolgloser Zündversuche für einen

vorbestimmten Zeitraum. Bei dieser

Störung leuchtet auch die LED zur

Störungssignalisierung direkt auf der

Steuerplatine.

Die Steuerplatine hat dem Flamm-

überwachungsgerät das Startsignal

übermittelt, aber das Signal des

erfolgten Starts nicht erhalten;

evtl. Flammenüberwachungsgerät

defekt.

- Circulation air fan faulty

- Inadequate cooling of the heat exchanger

- Capillary tube or sensor faulty

- Sensor positioned too close to heat exchanger

- Check safety thermostat for electrical continuity

- Seals faulty, warm exhaust gases make contact with the

sensor.

Note: The sensor is not only sensitive at its tip, but along its

entire length

Safety thermostat (STB)

Operation of safety thermostat.

If the temperature detected by

the thermostat is too high, the

same operates and blocks

operation of the unit.

- Gas supply not present or faulty

- Phase and neutral conductors interchanged

- Earth conductor missing or incorrectly connected

- Ignition electrode faulty or incorrectly ﬁ tted

- Monitoring electrode faulty or incorrectly ﬁ tted

- Flame monitoring device faulty

- Ignition gas nozzle clogged or incorrect size

Burner does not ignite

Fault of the ﬂ ame monitoring

device due to burner ignition

failure; the control board makes

several automatic reset attempts

prior to signalling the fault.

- Low-voltage cable to burner fan faulty or not connected

- Parameters A1 and A2 must correspond to the values in the

table in section “Control board replacement”.

- Burner fan faulty

- Burner board faulty

Burner fan faulty

The combustion air fan is faulty or

the signal to the control board is

outside the tolerance range with

respect to the requested speed.

- Check jumper on NTC for correct position

- Check sensor NTC1

- Check sensor NTC2 (only with temperature control)

Sensor NTC1 or NTC2 is

incorrectly displayed

NTC1 sensor faulty or not

connected – the sensor value is

outside the measuring range

- Check gas supply and gas components (see also F1)

- Replace control board if interlocks persist

Control board interlock

Control board fault due to

constant and repeated

unsuccessful ignition attempts of

the unit for a predeﬁ ned period.

- Check cable connection between ﬂ ame monitoring device

and control board

- Parameters A1 and A2 must correspond to the values in

the table in section “Control board replacement”.

- Flame monitoring device faulty

Flame monitoring device

The control board sent the

starting signal to the ﬂ ame

monitoring device, but did not

receive the started signal; it is

possible that the ﬂ ame

monitoring device is faulty.
