Make terminal hole all around 2mm larger than the diameter of the concentric system to prevent "ticking" and such like.The terminal hole does not require ventilation.If a clip binding is placed in a terminal hole, a hole diameter of Ø230 mm must be maintained.3-Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or ceiling. If the system is built in (for instance) a cove, it should be made with non combustible, heat-resistant material all around it. This does not apply to the insulated concentric system (DRU LAS ES-E 200/150/100).-Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell for a prolonged time; these are not suitable.The concentric system is constructed from (the flue spigot of) the appliance.If, due to constructional circumstances, the concentric system is placed first, it is possible to connect the appliance by means of a telescopic pipe piece.Place the concentric system as follows:1Build the system up from (the flue spigot of) the appliance.1Connect the concentric pipe pieces and, if necessary, the bend(s).1Apply a clip binding with silicon sealing ring on each connection (does not apply to DRU LAS ES-E 200/150/100, here the sealing ring is inside the tube).1Use a sheet metal screw to fix the clip binding to the pipe on locations that cannot be reached after installation.1Attach the concentric system with sufficient fastening brackets, so that the weight is not resting on the appliance.Observe the following;-Place the first fastening bracket 0.5 metre from the appliance, at the most.-Place a fastening bracket maximum 0.1 metre from each bend, if the bends are more than 0.25 metre away from each other. If two bends are closer to one another than 0.25 metre, 1 fastening bracket between these bends will be sufficient.-At least every 1 metre, place a fastening bracket at slanted and horizontal sections.-At least every 2 metres, place a fastening bracket at vertical sections.1Fasten a roof terminal with anchor cables, if it protrudes more than 1,5 metres above the terminal.1Determine the remaining length for the wall or roof terminal and cut it to size, make sure the correct insertion length is maintained.1Place the wall terminal with the (groove/folded) seam at the top.

7.3.2 Roof terminal (C31)The roof terminal can end in a sloping and a flat roof.The roof terminal can be supplied with an adhesive plate for a flat roof or with a universally adjustable tile for a sloping roof.When using a roof terminal (C31), the following applies:The construction of the chosen system has to be allowed. The working method below indicates how the permissibility is determined of a concentric system when using a roof terminal.1Count the number of 45° and 90° bends required (15° and 30° bends are also allowed; these are not counted).1Count the total number of whole metres of horizontal pipe length.1Count the total number of metres of vertical and/or sloping pipe length (roof terminal excluded).1Find the number of required bends and the total horizontal pipe length (see table 7-3, columns 1 and 2).1Find the required total vertical and/or sloping pipe length (see table 7-3, row 1).1A box with a letter means that the chosen concentric system is permitted.1Determine the adjustment of the appliance (see table 7-4).1Adjust the appliance correctly with, for instance, a restrictor slide and an air inlet guide (see section 8.2).3In the case of a roof terminal without bends: first connect 0.8 metres of concentric system with a diameter of 200/130 mm vertically to the appliance. After the first 0.8 metres, reduce the concentric system to a 150/100 mm diameter, including a 150/100 mm roof terminal.3In the case of a roof terminal with bends: first connect 0.8 metres of concentric system with a diameter of 200/130 mm vertically to the appliance. Make the concentric system with a 200/130 mm diameter up to and including the last bend, and reduce the concentric system immediately after this last bend to a 150/100 mm diameter, including 150/100 mm roof terminal.Installation manual27

7.3.3 Wall terminal (C11)When using a wall terminal (C11), the following applies:The construction of the chosen system has to be allowed.1Check that the vertical pipe length falls between the minimum and maximum lengths (see table 7-5).1Check that the horizontal pipe length (wall terminal excluded) falls within the minimum and maximum length (see table 7-5).2In the horizontal section, 1 bend of 90° may be included. This bend counts for 2 metres. This means that the maximum allowed length is reduced by 2 metres. A 45° bend counts for 1 metre.1Determine the correct adjustment of the appliance (see table 7-5).1Adjust the appliance correctly with, for instance, a restrictor slide and an air inlet guide (see section 8.2).The rosette of the wall terminal is too small to seal the opening in case of passage through combustible material. That is why a heat-resistant intermediate plate of sufficient size should first be mounted to the wall. Then, the rosette is mounted on the intermediate sheet.3When using a wall terminal, place the terminal with a downward slope of 1 cm / metre towards the outside, in order to prevent rain water from raining in.Installation manual30

Installation manual337.3.4 Connection to an existing chimneyThe appliance can be connected to an existing chimney (C91). A 100 mm diameter flexible SS pipe is placed in the chimney for discharging flue gases. The surrounding space is used as combustion air supply. Use the DRU spacer here. Place this spacer every three metres.In case of an appliance connection of ø200/130 mm, 0.8 metres of concentric system must first be connected vertically.Reduce the concentric system after the first 0.8 metres to a diameter of 150/100 mm. The concentric system of 150/100 can be connected to an existing chimney.The following requirements apply when connecting to an existing chimney:-Only allowed when used in combination with the special DRU chimney kit.-The internal dimensions should be at least 150 x 150 mm.-The vertical length has a maximum of 12 metres.-The total horizontal pipe length may have a maximum length (see table 7-3).-The existing chimney has to be clean.-The existing chimney has to be tight.For adjusting the appliance, the same conditions/instructions apply as for the concentric system described above.7.4 Placing the chimney breastFor a good heat discharge and operation of the appliance, there should be sufficient space around the appliance. The chimney breast should be ventilated sufficiently by means of ventilation holes (incoming and outgoing).3-When an appliance is built in the floor, please take into account the minimum distances from the floor/ground in front of the appliance (see fig. 7-12).-Use non combustible and heat-resistant material for the chimney breast, including the top of the chimney breast, the material inside the chimney breast and the back wall of the chimney breast.The appliance is not a support structure. Make sure the appliance does not have to bear the weight of the chimney breast for example.-The passage of the ventilation holes (outgoing) is stated in table 4-1. If it is not possible to use a control hatch in the chimney breast, an air supply of at least 80 cm2 must be placed as low as possible, but not above the burner surface. If a control hatch can be used, the control hatch will suffice as air supply (see section 7.5).

Installation manual343When placing the chimney breast, you should take the following into account:-The minimum dimensions of the chimney breast surround (see fig. 7-13).-The location of the control hatch: this must be placed as low as possible.-The distance of the control hatch up to the side of the appliance (see fig. 7-14).-The dimensions of the control hatch (see section 7.5).-The location of the ventilation holes (V-out).-A minimum 30 cm distance between the top of the ventilation hole (outgoing) and the ceiling of the house.-The dimensions of the glass pane, so that it can be placed/removed after placing the chimney breast.-The protection of the gas control and the pipes against cement and plaster.-Placement of decorative strips, frames and such like; if possible, install these after the carrying out any structural work. If this is not possible, protect them during this work. Avoid the use of painter's tape. If this is not possible: use good quality painter's tape and remove this tape immediately after plastering or painting work (prolonged application of painter's tape may cause damage).3You should preferably apply the ventilation holes (outgoing) on both sides of the chimney breast. Use the DRU ventilation elements.Check the following items, before the chimney breast is fully closed:-Is the discharge / concentric system placed correctly?-Have the channels, fastening brackets and possible clip bindings, that become inaccessible later, been secured with self-tapping screws?-Has no plastering work been performed on or across the edges of the construction frame? This due to the fact that:- the heat of the appliance could cause cracks;- It will no longer be possible to remove/place the glass pane.-When using stone-like materials and or plaster finishing, allow the chimney breast to dry for at least six weeks prior to taking the appliance into operation in order to prevent cracks.

7.5 Placing the control hatchA number of components are placed in the control hatch, such as data plate, gas control and, if applicable, components belonging to the DRU Powervent System®.The control hatch was designed in such a way, that all components as well as adjustment, measurement and regulating provisions are within optimum reach and the components work optimally. A control hatch placed and furnished on the side of the chimney breast ensures an optimum transmission and reception strength of the remote control and receiver. The control hatch also ensures sufficient aeration of the chimney breast. For that reason, the use of a control hatch is not without significance. Not using a control hatch could may void the warranty.3-The bottom of the control hatch may not be placed higher in the appliance than the burner surface.-Place the control hatch and bracket with gas control only indoors, on a dry spot!Place the control hatch as follows (see fig. 7-15):1Make an opening in the chimney breast as described in the manual for the control hatch (1).2The opening in the chimney breast may be made horizontal and vertical.1Place the inner frame. For this, first remove the outer frame with door (2).3The inner frame should be placed in the correct way. Two positions are possible. Placing the inner frame with a rotation of 180° is not allowed.2When the chimney breast is made of bricks, the inner frame can be built with bricks at the same time.In case of a different material, the inner frame can be glued or fastened with four countersunk screws.1Fix the outer frame with door (3) to the inner frame using two Allen screws.2The outer frame can be placed in such a way that the door turns to the left or right.1Attach the bracket with gas control to the inner frame. Proceed as follows:-Unwind the cables. This will, amongst other things, prevent a poor operation of the ignition (4).-Unwind the flexible gas pipe(s).-Mount the bracket with gas control to the inner frame. The slotted hole falls in Allen screw; the hole at the bottom falls over the head of Allen screw.-Fix the bracket with Allen screw.3-Avoid kinks in the pipes (4).-Do not lay the cables of the ionisation pin and spark electrode along metal parts, wiring and other components.1Connect the gas pipe with gas tap (6) (also see section 6.3).1Bleed the gas pipe (7).2If the gas tap is closed, the bracket with gas control can be easily removed by loosening the clamp coupling under the gas control and loosening the Allen screw (C) by a few turns. The bracket with the gas control can now be lifted and removed towards the front out of the control hatch.1Place the data plate in its intended clamp (8).1Connect the 230V mains voltage with protective earth using the correct type of plug. The other side of the power cable can be easily connected to the universal 230V plug in the control hatch. Use this universal 230V plug to disconnect the appliance from the power supply, if necessary.3If the 230V power cable is damaged, replace it by a similar power cable or a power cable that is available from your dealer.3Always close the control hatch with the lock (10), because of the electricity behind the door (230V). The lock is operated by means of a fitting flat object.Installation manual36

9.1 Principle of ignition cycleBelow you will find a brief description of how this appliance is ignited. The appliance is off and will be switched on by means of the remote control. The receiver in the appliance will get a signal from the remote control to start the ignition process. This signal is passed on to the burner device, after which, if applicable, the relay for the Powervent System® is switched. After an 8 second interval, the ignition on the spark electrodes will start. If no Powervent System® is connected, only the relay will switch and the appliance will ignite immediately. The main burner will be ignited at about 50% of its capacity. This will prevent a larger amount of gas in the combustion chamber, if no ignition takes place. When the gas ignites, ionization will have to be detected. In order to make sure the flame has passed over, this will take place at the other side of the burner. When ionization is detected, the gas control will modulate to 100%. In the case of a switchable second burner, the second valve is switched after this (you will be able to hear a 'click') in order to ignite the second burner. After ignition of the second burner, the appliance will always go to full output (full capacity). This will guarantee that the second burner will actually ignite. The second burner can be switched on and off manually, by means of the remote control. In case of switching on manually, the appliance will first return to full load.2The control unit of the appliance meets strict safety demands. It is possible that the burning appliance switches off automatically and then switches back on again. This is not a failure, but a check. The moment the appliance's control unit is connected to mains voltage, the control unit will perform this check every 24 hours. If the appliance is burning at that time, the appliance will extinguish and then start again immediately. This can be prevented by removing the plug from the socket and immediately inserting it again at a time when the appliance is never or hardly ever burning.9.2 Connecting the switch contact(if applicable)It is possible to operate one or more lamps (in case of several lamps, a maximum of 0,5A/250VAC/30VDC) via the remote control of the appliance. You could think of the lamps of Dru's lux elements. For this, you can use switch contact B on the receiver (see fig. 9-2). If the appliance is provided with LED lighting, switch contact ‘B’ is cancelled. The switch contact is not polar sensitive.

9.3 Connection extra power supply (max. 80W, 230VAC)(if applicable)This connection is ideal for possible lighting or a ventilation system in the chimney breast and can be operated by means of the remote control (see Fig. 9-2 (C)). The power supply of this connection is identical to the mains voltage and it can be subjected to a maximum load of 80 Watts.9.4 Remote controls9.4.1 Black remote control for the userProceed as follows to make the black remote control ready for use:1Place the two penlite batteries (AA) in the battery holder of the remote control.1Make sure the voltage of the appliance is not switched off for longer than 5 minutes.1If the remote control is not on 'BND', you must proceed as follows:1Press the 'menu' button (button with square symbol) on the remote control for at least 10 seconds and then press a few times until 'BND' appears on the screen with the receiving symbol.1Press the 'arrow up' and 'arrow down' buttons briefly and simultaneously, so that a (flashing) warning triangle and an hourglass appear in the screen as well.1As soon as logging on is finished, the start screen will appear2All functions are extensively explained in the supplied user manual.9.4.2 Orange remote control for the installerBy means of the optionally available orange remote control, it is possible to read all information stored in the receiver. In this way, the last 20 error messages can be retrieved, and it will also be possible to read how many times an error occurred. Moreover, this remote control can also be used to adjust the basic settings and to read the magnitude of the ionization current. This remote control is also necessary for a wired home automation control.9.5 Alternative operation(if applicable)In addition to the remote control, it is also possible to operate the appliance via an external source. For this purpose, a home automation system can be connected to the receiver. This can be both wired and wireless (see sections 9.5.1. and 9.5.2).Installation manual55

9.5.1 WiredWired connection of the home automation system to the receiver takes place via a 0-3VDC direct current (see fig. 9-2 (D)).3A higher voltage than 3V will damage the receiver and is therefore not permitted.2In case of home automation systems with an output voltage of 0-10V, you should switch the voltage back to 0-3VDC. Use a voltage distributor made of resistors. For example, 2200 ohms and 680 ohms. The voltage above 680 ohms resistance can be used on the input of the 0-3VDC. Low ohmic resistors must be used.By controlling the height of the voltage, the receiver will be able to calculate the position of the appliance. Graph 9.1 shows the relationship between the voltage, the height of the flame and the number of burners (1 or 2).Proceed as follows when connecting the home automation system to the receiver:1Connect the 0-3VDC signal to the connector, to which a black and yellow wire are connected (see fig. 9-2 (D)).1Use the orange remote control to set the option for wired connection: go to position 8 in the first menu and select option 2 for an appliance with one burner and option 3 for an appliance with two burners. For this, read the manual for the orange remote control.3The yellow wire is the + pole, the black wire is the - pole. Always connect ‘- to -‘ and ‘+ to +’ .Installation manual56

9.5.2 WirelessThe wireless connection is divided into 2 types:-Connection via a ‘modbus’ protocol.-Control via an application.3Only 1 type of wireless connection is possible on the communication module.9.5.2.1 Connection via ‘modbus’ protocolWireless connection of a home automation system to the receiver is possible via a connection according to the ‘modbus’ protocol. Such a connection can only be established with a communication module (see fig. 9-1 (W)). This module can be ordered from DRU. This communication module translates the ‘modbus’ protocol from the home automation system into a wireless signal to the receiver.When connecting a home automation system via the communication module to the receiver, proceed as follows:1Use the remote control to test whether the location where the communication module will be placed is within the reach of the receiver.1Place the remote control on this location and test the reception sensitivity (RSSI).1Press the 'on/off' button and 'down arrow' at the same time. The value that is now visible, must be between -20 and -70 (see User Manual, “Reception Sensitivity”). If needed, hold the remote control closer to the appliance in order to improve the reception.1Connect the communication module by means of an RJ45 plug, according to the instructions in the manual that is supplied with this module.1Now follow the steps described in the ‘modbus’ protocol manual. It is available from the supplier of the home automation system.9.5.2.2 Control via applicationAlso when operating the appliance via a tablet provided with the DRU Control App (iOS or Android), you will need a communication module. This module can be ordered from DRU.In order to control the application via the DRU Control App, proceed as follows:1Use the remote control to test whether the location where the communication module will be placed is within the reach of the receiver.1Place the remote control on this location and test the reception sensitivity (RSSI).1Press the 'on/off' button and 'down arrow' at the same time. The value that is now visible, must be between -20 and -70 (see User Manual, “Reception Sensitivity”). If needed, hold the remote control closer to the appliance in order to improve the reception.1Connect the communication module by means of an RJ45 plug, according to the instructions in the manual that is supplied with the communication module.1Use the instructions for the application in order to install it.3-The DRU Control app functions in accordance with the multicast and communication protocol. Ensure the router is equipped with this. For this, consult the router's installation manual.-If the DRU Control app is used, the thermostat function no longer applies. The ‘DRU Control’ application is available from the Appstore, via GooglePlay or the DRU website: www.drufire.comInstallation manual57

10. Final inspectionFor a good and safe operation of the appliance, the following checks must be performed prior to commissioning.10.1 Gas tightness3All connections must be gas tight. Check the connections for gas tightness. The gas control can be subjected to a maximum pressure of 50 mbar.10.2 Gas pressure/line-pressureThe burner pressure is set at the factory; see data plate.3The line-pressure in house installations must be checked, because it can be wrong.1Check the line-pressure. See fig. 6-1 (P1) for the measuring nipple on the gas control.-Contact the gas company if the line-pressure is too high.-If the line-pressure is too low, check this at the gas meter. Contact the gas company if the line-pressure is also too low at the gas meter.10.3 Ignition main burnerFor igniting the main burner, see the User Manual.10.3.1 First ignition of the appliance after installation or adjustments3After installation, or after work has been performed, you should ignite the appliance for the first time without the glass pane. If necessary, bleed the gas pipe.Proceed as follows:1. Remove the glass pane from the appliance (see chapter 8).2. Start the ignition procedure as described in the User Manual.The appliance ignites on the main burner with 50% of the full output. Once the flame has passed over the main burner to the ionization and a flame has been detected, the appliance will modulate to 100%. This detection will have to take place within 15 seconds, or else the appliance will enter error mode. If the appliance has a second, separately switchable burner and the main burner continues to burn, the second valve will switch in order to ignite the second burner. Here, you can hear a clear ‘click’ sound. (Go to step 11 if the burner continues to burn).If the main burner does not ignite:3. Reset the system by pressing the buttons ‘arrow up’ and ‘arrow down’ simultaneously.4. Repeat the ignition procedure until the main burner ignites.3The system can be reset and re-ignited two times in a row at maximum. Then the system will enter a hard lock-out and you will have to wait half an hour, before you can make a new attempt. Never use more than 3 attempts to ignite the appliance, as this could lead to a accumulation of gas within the appliance. Make sure that there is nomore gas in the appliance before making 3 new ignition attempts.1If you do not succeed after a few attempts, consult the diagram with error messages (see appendix 1: Malfunctions).5. Check the flame transfer on the main burner and check whether the main burner continues to burn (go to step 11 if the burner continues to burn).If the main burner does NOT continue to burn:6). Mount the glass pane.7). Reset the system by pressing the buttons ‘arrow up’ and ‘arrow down’ simultaneously.8). Now ignite the main burner and check whether it continues to burn (go to step 12 if the burner continues to burn).3Limit the ignition attempts with mounted glass pane to a MAXIMUM of 1 ignition attempt.If the main burner again does NOT continue to burn:9). Switch off the appliance.10). Consult the diagram with error messages (see appendix 1: Malfunctions) (Go to step 1 once the malfunction has been remedied).Installation manual58

If the main burner DOES continue to burn:11. Clean the glass pane before using it for the first time, as described in the user manual. Then mount the glass pane as described in chapter 8.12. Repeat the ignition procedure a few times and perform the checks described in section 10.3.2.13. From now on, the main burner should ignite smoothly and continue to burn.14. Clean the glass pane after burning for the first time, as described in the user manual.3Always wait 5 minutes before re-igniting the appliance.10.3.2 Procedure for igniting the main burner3-The ignition electrode should ignite the main burner(s) within a couple of seconds and without popping.-The main burner(s) must pass over fluently without popping, covering the entire burner, and continue to burn.-If the appliance does not ignite after 2 restarts and enters hard lockout, it may never be reset by disconnecting the appliance from the power supply. If a restart is necessary after all: remove or open the glass pane and make sure the gas is able to escape from the appliance. After this, the appliance may be disconnected from the power supply for 10 sec. After these 10 sec., the power supply may be reconnected.Ignite the appliance in the same way as the first ignition, as indicated in section 10.3.1.1Check operation of the main burner from a cold condition.1If sparks are determined between the ignition electrodes, the main burner should burn within a few seconds.3If NO sparks are determined, it is NOT permitted to continue the procedure.Consult the diagram with error messages (appendix 1: (Malfunctions) if the ignition of the main burner does not comply with the above-mentioned requirements.2The flame picture and a good flame transfer can only be properly judged if the glass pane is installed or closed.10.4 Flame pictureThe flame picture can only really be assessed when the appliance has been burning for several hours. Volatile components from paint, materials, etc., which evaporate in the first hours, will affect the flame image.1Check that the flame picture is in order.1Consult the diagram with error messages (appendix 1: Malfunctions) if the flame picture is not in order.Installation manual59

11. DeliveryFamiliarise the user with the appliance. Provide the user with instructions on putting it into operation, the safety measures, the operation of the remote control and annual maintenance (see the User Manual).3-Tell the user to close the gas tap immediately and contact the installer in case of malfunctions/poor operation. This to prevent unsafe situations.-Chapter 9 of the manual supplied applies to an appliance equipped with the CM system.-Indicate the location of the gas tap.-Point out the precautions in the User Manual against unintended ignition by other wireless remote controls such as car keys and garage door openers.-Point out the 230 Volt connection.1Instruct the user about the appliance and the remote control.1When taking the appliance into operation, point out the following:-In order to prevent cracks, a chimney breast made of stone-like materials or finished with plaster, must dry at least 6 weeks prior to taking the appliance into operation.-Chapters 10 and 11 of the manual supplied apply to an appliance equipped with the CM system.-Volatile components from paint, materials, etc., evaporate when burning the appliance for the first time (read chapter 3 of the User Manual!).-During evaporation, preferably set the appliance to the highest position.-Make sure the room is properly ventilated.-Cleaning the glass pane(s).1Give the manuals to the user (all manuals should be stored near the appliance).Installation manual60

12. MaintenanceOnce per year, the appliance must be checked, cleaned and, if necessary, repaired by a competent installer in the field of gas heating and electricity. At least check that the appliance is working properly and safely.3-Always close the gas tap during maintenance work.-Check the gas tightness after repair.-Make sure there is no voltage on the appliance.-SS-absolutely do not clean the concentric system (internally) with a steel brush or metal sponge, for example.This will damage the oxide skin and could lead to leaks in the system as a result of pitting corrosion.1Clean the glass pane(s), if necessary.3-Only clean a glass pane once it has reached room temperature.-Do not use the appliance when a glass pane is broken and/or cracked, until it has been replaced as described from section 8.1.3-Avoid damage to the glass pane(s).-Avoid/remove fingerprints on the glass pane(s), since otherwise they will burn into the surface.-Clean the pane(s) as described in the user manual.-Regularly remove accumulated dirt, as it can burn into the glass.1Inspect the flue gas discharge system.3You must always perform a final inspection.1Perform the inspection as described in chapter 10.12.1 PartsComponents that have to be replaced are available at the supplier.Installation manual61
