Ins t all at ion m an u a l 1. Step-by-step installation plan The major steps of the installation are described below, Perform these steps and tick them once they have been performed correctly. Carefully read the installation manual before installing the appliance. Check that the correct type of appliance has been delivered (see table 4-1).
Fully and carefully read and use this installation manual, before installing the appliance. When using the DRU PowerVent® system or DRU CM system, the accompanying installation manual should also be read completely and carefully, before installation work begins.
* This appliance is suitable for G25.3 with the composition according NTA 8837. ** System efficiency. *** To be used by means of home automation. **** Adjusting screw. *****Categories C12 and C13 only in combination with DRU PV-1 100/60 (PowerVent®).
- Only use the flue gas discharge / combustion air supply system (concentric system) supplied by DRU. When installing a free-standing appliance: place the appliance at the indicated minimum distance from the back wall, as indicated further down in the text.
Check whether the appliance is suitable for the type of gas and the gas pressure used at the location. 6.2.1 Gas type conversion In order to convert this appliance to a different type of gas, please contact DRU's service department and ask for the possibilities. The conversion should be performed by a recognised gas installer.
If legally permitted, a gas hose for a gas socket (in accordance with EN14800) can be ordered for the appliance. (Please consult DRU service.). The gas hose is mounted to the appliance and has been checked for leak-tightness. This gas hose is available in different lengths.

7.3 Concentric system 7.3.1 General The appliance is connected to a flue gas discharge / combustion air supply system delivered by DRU, hereafter referred to as the concentric system. DRU has different concentric systems in its range. In the case of a concentric system, the inner tube is used as flue gas discharge. The combustion air is supplied by the outer tube.
Page 26
Build the system up from (the flue spigot of) the appliance. Connect the concentric pipe pieces and, if necessary, the bend(s). Apply 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).
My Flue Assist is a DRU web application to check whether an intended concentric system is permissible and provides advice on how to adjust the appliance. Go to the DRU Service website for My Flue Assist. The information from the installation manual is always leading.

Before installing the wood set, adjusting the appliance or maintenance, the glass pane must be removed. 8.1.1 Opening the glass pane Proceed as follows to open the glass pane (see fig.
Ins t all at ion m an u a l 8.1.2 Closing the glass pane Close the glass pane once it has been cleaned. Proceed as follows to close the glass pane (see fig. 8-2). Close the glass pane by pushing the profile at the top of the glass pane towards the appliance (1). The glass pane will close automatically.
Ins t all at ion m an u a l 8.1.3 Removing glass pane Proceed as follows to remove the glass pane (see fig. 8-3): Open the glass pane (see section 8.1.1). Swivel the catch brackets out of the holder by pulling them inwards (1). Slide the catch brackets inwards so that they cannot obstruct the work, but ensure that they can be reached later.
Ins t all at ion m an u a l 8.1.4 Reinstalling glass pane Reinstall the glass pane once the appliance has been correctly adjusted, the wood set has been installed, the glass pane is clean or following maintenance. Proceed as follows to reinstall the glass pane (see fig. 8-4). Grasp the glass pane on both sides at the bottom and hold the pane at the angle of the open position (1).
Ins t all at ion m an u a l 8.2 Adjusting the appliance The appliance must be set up in such a way that it works correctly in combination with the smoke exhaust system. For this purpose, a restrictor slide may be installed, or the air inlet guide removed or replaced. The conditions for use with wall and roof terminal are indicated in tables 7-3 to 7-5.
Ins t all at ion m an u a l 8.2.2 Air inlet guide Air inlet guide 1 is fitted and air inlet guide 2 is supplied separately. To replace or remove air inlet guide 1, proceed as follows (see fig. 8-6): Remove the glass pane from the appliance (see section 8.1.3).
Ins t all at ion m an u a l 8.3 Wood set The appliance is supplied with a wood set. The figures do not always show the correct colours. Observe the instructions below to prevent unsafe situations: - Only ever use the supplied wood set. - Place the wood set exactly as described.

Ins t all at ion m an u a l 9. Control/operation The appliance is supplied with a wireless black remote control for the user (see fig. 9-1 (B)). As an option, an orange remote control can be supplied for the installer (see fig. 9-1 (O)). Flame height, ignition and switching off are controlled by the black remote control controlling the receiver.
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.
Ins t all at ion m an u a l 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.
Ins t all at ion m an u a l 9.5.1 Wired Wired connection of the home automation system to the receiver takes place via a 0-3VDC direct current (see fig. 9-2 (D)). A higher voltage than 3V will damage the receiver and is therefore not permitted. In case of home automation systems with an output voltage of 0-10V, you should switch the voltage back to 0-3VDC.
9.5.2.2 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 application via the DRU Control App, proceed as follows: Use the remote control to test whether the location where the communication module will be placed is within the reach of the receiver.
Ins t all at ion m an u a l 10. Final inspection For a good and safe operation of the appliance, the following checks must be performed prior to commissioning. 10.1 Gas tightness All connections must be gas tight. Check the connections for gas tightness. The gas control can be subjected to a maximum pressure of 50 mbar.
Ins t all at ion m an u a l 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.
Ins t all at ion m an u a l 11. Delivery Familiarise 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). - Tell the user to close the gas tap immediately and contact the installer in case of malfunctions/poor operation.
Ins t all at ion m an u a l 12. Maintenance Once 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. - Always close the gas tap during maintenance work.
