2.3 The correct fill and make-up water
Note the fundamental system-specific water quality
requirements.
Water designation
Water is used as the heat transfer medium in your heating
system. Depending on its purpose, the water is given
different descriptions.
•Heating water:
Water contained within your heating system.
• Fill water:
Water used for the first filling of your system before
commissioning.
• Make-up water:
Water used for topping up the heating system in case
of water loss.
Water quality requirements
All water contains substances, e.g. Ca (HCO
3
)
2
(calcium
hydrogen carbonate) that could affect the operation of
your heating system. These can cause corrosion, scale
formation or deposits.
To ensure your heating system always operates
economically, properly and safely, not to mention in an
energy-efficient manner, we recommend that you regularly
monitor the quality of the fill and make-up water and treat
it accordingly as and when necessary.
For the correct use and treatment of the fill and make-up
water, the contents of the following table MUST be
observed.
NOTICE: System damage from corrosion or
scale formation as the result of using fill and
make-up water that does not conform to the
system-specific requirements.
B Ask your trained and certified installer or
local water company what the
concentration of Ca (HCO
3
)
2
(calcium
hydrogen carbonate) is in your area.
B If the fill and make-up water does not meet
system-specific requirements, it will have
to be treated. Consult your trained and
certified installer if this is the case.

2.4 The correct fuel
To ensure it operates properly, the heating system
requires fuel of the correct type and grade.
NOTICE: Risk of system damage from use of
incorrect fuel.
B Only use the fuel specified. The correct
fuel is entered in Æ Tab. 3 by the heating
contractor.
Use the following fuel:
Stamp/Signature/Date
Tab. 3 Fuel to be used (entered by heating contractor)
We recommend you seek the advice of your
system installer if you intend changing the
fuel for your system.

3 System start-up
This chapter explains how you prepare the system for
operation and how to commission the control panel and
the burner.
3.1 Making the system operational
You should check the following to prepare the system for
operation:
B Operating pressure of the system (Æ Chapter 3.2)
B Fuel is supplied and the main fuel shut-off valve is open
B Heating system emergency shutoff switch set to ON
Ask your heating contractor to show you where the fill
valve for your heating system (boiler return) is located.
3.2 Check and correct the operating
pressure
Your heating system must contain sufficient water to
ensure the functionality of your system.
If the operating pressure in the system is too low, fill make-
up water into your system (Æ Chapter 2.3, page 6).
• Recently added fill or make-up water loses much of its
volume in the first few days because it releases gases.
With newly filled heating systems, initially check the
operating pressure daily and then in ever increasing
intervals.
• Once the system is barely losing any volume, check the
operating pressure of the heating water once a month.
All factory default settings will have already been made by
the heating contractor when the system was first
commissioned.
3.2.1 Checking the operating pressure
The operating pressure must be at least 15 psi (1 bar).
B Read the current operating pressure and temperature
(°F (°C)) from the temperature/pressure gauge.
B If the operating pressure drops below 15 psi (1 bar),
top up heating water.
Fig. 3 Pressure/temperature gauge
3.2.2 Topping up with heating water and bleeding
the system
B Slowly fill the heating system via the on-site fill valve.
During filling, observe the display (pressure gauge).
B Once the desired operating pressure is reached, stop
the procedure.
B Bleed the heating system via the central purging
station.
B Top up with water again if the operating pressure drops
as a result of bleeding the system.
NOTICE: Risk of system damage due to
frequent topping up.
B If you need to add water frequently, the
heating system may be damaged by
corrosion and scale buildup depending on
the water quality.
B Bleed the heating system. If necessary,
top up heating water.
B Check the heating system for leaks and
the correct operation of the expansion
vessel.
B Notify your heating contractor if you find
you need to top up your heating system
frequently.
Air pockets may form in the heating system
from the fill or make-up water releasing
gases.
Let your local heating contractor show you
where the boiler fill and drain valve for
topping up and draining the heating water is
located on your heating system.

3.3 Starting up the control panel and the
burner
Start your boiler via the control panel (Æ Fig. 4). By
starting the control panel, you also automatically start the
burner. The burner is then fired by the control panel. For
further details, see the operating instructions of the
relevant control panel or burner.
B Switch the boiler water thermostat (Æ Fig. 4, [1]) to
"AUT."
B Set the ON/OFF switch (Æ Fig. 4, [2]) to "I" (ON).

4 Shutting down the system
This chapter explains how you shut down your boiler and
switch off the control panel and the burner. Furthermore,
it contains details on how to shut down your heating
system in an emergency.
B Shut off the fuel supply at the main fuel shut-off valve.
4.1 Switching off the control panel and
the burner
Shut down your boiler via the control panel (Æ Fig. 4).
The burner is automatically shut down when the control
panel is switched off.
B Set the ON/OFF switch (Æ Fig. 4, [2]) to "0" (OFF).
4.2 Shutting down the system in an
emergency
In other dangerous situations, immediately disconnect the
heating system from the electrical power grid by shutting
off the emergency shutoff switch or by disengaging the
heating system circuit breaker (Æ Chapter 1.2, page 3).
NOTICE: Risk of system damage from
freezing.
B The system can freeze up if it is disabled,
e.g. because of fault(s).
B Protect your system from frost damage
where freezing temperatures can be
expected.
B Drain the heating water at the lowest point
in the system, using the boiler fill and drain
valve. To do this, open the purger at the
highest point in the system.
For further details on this subject, see the
operating instructions for the relevant control
panel.
Only in emergencies, switch off the system
via the heating system emergency shutoff
switch or by disengaging the heating system
circuit breaker.

5 Correcting burner faults
Heating system faults are shown on the control panel
display. You will find detailed information regarding fault
displays in the service instructions for the relevant control
panel. The burner fault is also indicated by a fault lamp on
the burner.
B Press the burner reset button (see burner operating
instructions).
If the burner does not restart after three attempts, refer to
the technical documentation provided with the burner to
find out how to reset it.
NOTICE: Risk of system damage from
freezing.
B The system can freeze up if it is disabled,
e.g. because of fault(s).
B If the system remains switched off for
several days because of a fault, drain the
heating water via the fill and drain valve at
the lowest point.
NOTICE: Risk of system damage due to too
many resets.
B The burner ignition transformer may be
damaged if you press the reset button
more than three times in succession when
the burner refuses to start.
B Do not attempt to remedy the fault by
pressing the reset button more than three
times in succession.
