INSTALLATION MANUAL3.4 Principle of ignition cycle
Below you will find a brief description of how this appliance is ignited. The receiver in the appliance will get a signal from the remote control to start the ignition process. The receiver will get the signal 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 ignition will start 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 case of an appliance with a switchable second burner, the second valve is switched (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 the full position (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.
!Caution The appliance's control unit is characterized by stringent safety requirements. 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.If you wish to prevent this, you can remove the plug and insert it again at a time during the 24 hours when the appliance is never or hardly ever burning.
4. Removing the packaging
Note the following items when removing the packaging:
Ø Remove all packaging materials.
Ø Remove all supplied components in, on and/or at the appliance.
Ø Check the appliance and accessories for damages (during transport).
Ø If necessary, contact your supplier.
Ø Never install if an appliance is damaged!
Ø Remove any screws that are used to fix the appliance to a platform or pallet.
!Caution Glass is a ceramic material. Very small irregularities in the glass panes cannot be avoided, but are within the required quality standards.
!Caution Keep plastic bags away from children. Appendix 2, table 1 indicates which components should be available after unpackaging.
Ø Contact the supplier if you find that not all components have been supplied.
Ø Packaging must be disposed of in accordance with the regulations.

INSTALLATION MANUAL5.8 Concentric system5.8.1 General
The appliance is connected to a flue gas discharge / combustion air supply system delivered by DRU, hereafter referred to as the concentric system. The diameter for this connection is indicated in appendix 2, table 2. The passage to the outside can be created with a wall terminal (C11) or a roof terminal (C31). If necessary, an existing chimney can be used (see section 5.8.4).
!Caution •Only use the concentric system supplied by DRU. This system has been tested in combination with the appliance. DRU cannot guarantee a proper and safe operation of other systems and does not accept any responsibility or liability for this.•Use a chimney set for the connection to the chimney, DRU will be able to supply it.•DRU's concentric system is intended for indoor use and may therefore not be used outdoors, with the exception of the sections intended for that purpose such as roof and wall terminals. 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.
5.8.2 Construction of the concentric system
Depending on the configuration of the concentric system, the appliance must be further adjusted with a possible restrictor slide and/or air inlet guide.See Tables 4 and 6 for determining the correct adjustment and section 'Adjustment of the appliance' for the method of working. The concentric system with wall or roof terminal has to comply with the following conditions:•In appendix 2, table 4 or 5 you can find whether a concentric pipe should be connected and what the minimum vertical length would have to be.•Determine the permissibility of the required configuration. When using a wall terminal (C11) the following applies:•The total vertical pipe length, when using a wall terminal, may have a maximum length that can be found in appendix 2, table 4.•The minimum vertical pipe length, when using a wall terminal, can be found in appendix 2, table 4.•The total horizontal pipe length, when using a wall terminal, may have a maximum length that can be found in appendix 2, table 4 (excluding wall terminal; see appendix 3, fig. 5). When using a roof terminal (C31) the following applies:•The construction of the chosen system, when using a roof terminal, must be permissible according to Appendix 2, Table 5 (See the method of working described below). The working method below indicates how the permissibility is determined of a concentric system when using a roof terminal.1) Count the number of 45° and 90° bends required (15° and 30° bends are also allowed).2) Count the total number of whole metres of horizontal pipe length.3) Count the total number of metres of vertical and/or sloping pipe length (roof terminal excluded).4) In the first 2 columns of Table 5, look for the number of bends required and the total horizontal pipe length.5) In the top row of Table 5, look for the required total vertical and/or sloping pipe length.6) A box with a letter means that the chosen concentric system is permitted.7) Use Table 6 to determine how the appliance should be adjusted.

English
INSTALLATION MANUAL5.8.3 Placing the concentric system!Caution
•Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling (see section 5.4). If the system is built in (for instance) a cove, it should be made with non combustible, heat-resistant material all around it.•Use heat-resistant insulation material when passing through combustible material.•Create a terminal for the concentric system with the following diameters:- The pipe diameter +25 mm for a passage through non combustible material (see Appendix 3, fig. 40).- The pipe diameter +200 mm for a passage through combustible material. Insulate the surrounding free space with at least 60 mm mineral wool (see Appendix 3, fig. 41).•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. 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.
!Caution Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell for a prolonged time; these are not suitable. Place the concentric system as follows:
Ø Build the system up from (the flue spigot of) the appliance.
Ø Connect the concentric pipe pieces and, if necessary, the bend(s).
Ø On each connection, apply a clip binding with silicon sealing ring.
Ø Use a self-tapping screw to fix the clip binding to the pipe on locations that cannot be reached after installation.
Ø Apply sufficient wall brackets, so that the weight of the pipes does not rest on the appliance.
Ø Determine the remaining length for the wall or roof terminal and cut it to size, make sure the correct insertion length is maintained.
Ø Place the wall terminal with the (groove/folded) seam at the top.
Ø Attach the wall terminal from the outside by means of four screws.
!Caution When using the 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.
5.9 Connection to an existing chimney (C91)
The appliance can be connected to an existing chimney. 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.In case of an appliance connection of ø200/130, 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. The concentric system of 150/100 can be vertically 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 set. The installation regulation is parat of the delivery.•The internal size should be at least 150 x 150 mm.•The vertical length has a maximum of 12 meters.•The total horizontal pipe length may have a maximum length that can be found in appendix 2, table 4.•The existing chimney should be clean.•The existing chimney should be tight.

INSTALLATION MANUAL6. Control
The appliance is supplied with a wireless black remote control for the user (see appendix 3, fig. 35 (B)). As an option, an orange remote control can be supplied for the installer (see appendix 3, fig. 35 (O). Controlling the flame height, igniting and switching off take place through the black remote control controlling the receiver. Some fires can also be controlled in an alternative way. These options are described further down in this chapter.The user manual describes the operation of the appliance, including the operation of the remote control and alternative methods of operation.
!Caution •Do not ignite the appliance before the gas, discharge and electric connections have been fully installed, first observe the procedure described in chapter 7.3.•Chapter 6 of the manual supplied applies to an appliance equipped with the CM system.
6.1 Remote controls6.1.1 Black remote control for the user
Proceed as follows to make the black remote control ready for use:
Ø Place the two penlite batteries (AA) in the battery holder of the remote control.
Ø Make sure the voltage of the atmospheric fire is not switched off for longer than 5 minutes.
Ø If the remote control does not have the "BND" state, the following operations must be performed: Press 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.
Ø Press 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.
Ø As soon as logging on is finished, the start screen will appear
!Tip Ale functions are extensively explained in the supplied user manual.
6.1.2 Orange remote control for the installer
By 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 size of the ionization flow. It is also required for a wired Domotics control.
6.2 Alternative control (if applicable)
In addition to the remote control, it is also possible to operate the fire in alternative ways. For this purpose, a Domotics system can be connected to the receiver. This can be a wired or a wireless system. The various possibilities are described below (see appendix 3, fig. 35, 36 and 37).
6.2.1 Wired
Wired connection of the Domotics system to the receiver takes place via a 0-3VDC direct current(see appendix 3, fig. 36 (D)).
!Caution A higher voltage than 3V will damage the receiver and is therefore not permitted.
Tip! In case of Domotics 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 fire. Table “B1” in appendix 3, fig. 37 shows the relationship between the voltage and the height of the flame. If you have an appliance with 2 burners, table “B2” will apply. It shows the relationship between the voltage, the height of the flame and the number of burners.Proceed as follows when connecting the Domotics system to the receiver:
Ø Connect the 0-3VDC signal to the connector, to which a black and yellow wire are connected(see appendix 3, fig. 36 (D)).
Ø Use the orange remote control to select the option for a wired connection: go to position 8 in the first menu and select an appliance with single burner (option 2) or an appliance with two burners (option 3). For this, read the manual of the orange remote control.

6.2.2 Wireless
The wireless connection is divided into 2 types:•Connection via a ‘modbus’ protocol.•Control via an application.
!Caution Only 1 type of wireless connection is possible on the communication module.
6.2.2.1 Connection via ‘modbus’ protocol
Wireless connection of a Domotics 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 Appendix 3, fig. 35 (W)). This module can be ordered from DRU. This communication module translates the ‘modbus’ protocol from the Domotics system into a wireless signal to the receiver.When connecting a Domotics system via the communication module to the receiver, proceed as follows:
Ø Use the remote control to test whether the location where the communication module will be placed is within the reach of the receiver.
Ø Place the remote control on this location and test the reception sensitivity (RSSI).
Ø Press 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.
Ø Connect the communication module by means of an RJ45 plug, according to the instructions in the manual that is supplied with this module.
Ø Now follow the steps described in the ‘modbus’ protocol manual. It is available from the supplier of the domotics system.
6.2.2.2 Control via application
Also 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 fire via an application, proceed as follows:
Ø Using the remote control, test whether the location where you want to place the communication module is within the receiver's range.
Ø Place the remote control on this location and test the reception sensitivity (RSSI).
Ø Press 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.
Ø Connect the communication module by means of an RJ45 plug, according to the instructions in the manual that is supplied with the communication module.
Ø Use the instructions for the application in order to install it.

INSTALLATION MANUAL7. Final inspection
In order to check whether the appliance is working properly and safely, you must perform the following inspections before the appliance is put into operation.
7.1 Gastightness!Caution
All connections must be gastight. Check the connections for gastightness.The gas control may be subjected to a maximum pressure of 50 mbar.
7.2 Gas pressure/line-pressure
The burner pressure is set at the factory; see data plate.
!Caution The line-pressure in house installations must be checked, because it can be wrong.
Ø Check the line-pressure; see Appendix 3, Fig 38 (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.
7.3 Ignition main burner
For igniting the main burner, see the User Manual.
7.3.1 First ignition of the appliance after installation or adjustments.!Caution
After installation, or after work has been performed, you should ignite the appliance for the first time without the glass window. If necessary, bleed the gas pipe. Follow the procedure described below:
Ø If necessary, remove the glass pane.
Ø Start the ignition procedure as described in the user manual.
Ø If the main burner does not ignite:•Reset the system by pressing the buttons ‘arrow up’ and ‘arrow down’ simultaneously.•Repeat the ignition procedure until the main burner ignites;
!Caution After each attempt to ignite, the system should be reset by means of the remote control.
Ø Consult the diagram with error messages (Appendix 1) if this does not succeed after a few attempts; The appliance ignites at 50%. After ionization 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 applicable, the second valve will switch to ignite the second burner. Here, you can hear a clear ‘click’ sound.
Ø Check whether the main burner continues to burn.
Ø If the main burner does not continue to burn:Reset the system as described and repeat the ignition procedure until the main burner continuous to burn.
!Caution The system can be reset and re-ignited three 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.
Ø Consult the malfunction search diagram (Appendix 1) if this does not happen after a few attempts.
Ø Switch off the appliance.
Ø Then mount the glass window as described from chapter 5.10.
Ø Repeat the ignition procedure a few times and perform the checks described in chapter 7.3.2.
Ø From now on, the main burner should ignite smoothly.
Ø Clean the glass pane after igniting for the first time (see section 8).
!Tip When checking whether the main burner continuous to burn, it is possible that it switches off after 15 seconds. In that case, this will be caused by the fact that there is no ionization detection and because the glass window has not been placed. This can be regarded as a situation where the main burner continues to burn.
