INSTALLATION MANUAL
3.4 Principle of ignition cycle
Below 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 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 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%.
If applicable, 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 its 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.
In Appendix 2, Table 1 you can see which parts you should have after removing the packaging.
Ø Contact your supplier if you do not have all the parts after you finished removing the packaging.
Ø Packaging must be disposed of in accordance with the regulations.

INSTALLATION MANUAL
5.9 Flue gas discharge /combustion air supply system at appliances with a closed
combustion
5.9.1 General
The appliance's type of discharge system is stated in Appendix 2, Table 2.
The appliance is connected to a combined flue gas discharge/combustion air supply system, hereafter referred to
as the concentric system.
The passage to the outside can be made with both a wall terminal and roof terminal.
If necessary, you can also use an existing chimney (see section 5.9.4).
!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;
• For connecting to an existing chimney you should only use the chimney kit supplied by DRU.
• 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.
5.9.2 Construction of the concentric system
Depending on the construction of the concentric system the appliance will have to be further adjusted with
possibly a restrictor slide or air inlet guide.
See Tables 4 and 6 for determining the correct adjustment and section 5.9, '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 discharge.
When using a wall terminal the following applies:
• The total vertical pipe length, when using a wall terminal, may have a maximum length that you can find 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 you can find
in Appendix 2, Table 4 (without wall terminal; see Appendix 3, Fig. 5).
When using a roof terminal 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;
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) If you end up in a box with a letter, the concentric system chosen by you is permissible;
7) Use Table 6 to determine how the appliance should be adjusted.
