- the location of the control hatch: this must be placed as low as possible;
- the dimensions of the control hatch; see Placing the control hatch section 5.6;
- the Dru control hatch is not supplied with all appliances. Nevertheless, we recommend only using a Dru
control hatch, which can be supplied separately, if necessary. If you decide not to take this option, you will
have to make a 100 cm2ventilation hole that is placed as low as possible, for the benefit of the incoming
ventilation.
- the location of the ventilation holes (V) (outgoing);
- maintain a minimum 30 cm distance between the top of the ventilation hole (outgoing) and the ceiling of
the house.
- the measurements 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.
!Tip You should preferably apply the ventilation holes (outgoing) on both sides of the chimney breast. You can use
DRU ventilation elements.
- Prior to completely closing the chimney breast, check whether the discharge / concentric system is placed
correctly.
- whether the channels, fixing brackets and possible clip bindings, which cannot be reached after installation,
are fastened by means of self-tapping screws.
Ø If applicable, do not plaster on or over the edges of the construction frame, because:
- the heat of the appliance could cause cracks;
- it will no longer be possible to remove/place the glass pane.
Ø When using stone-like materials and/or a plaster finishing, allow the chimney breast to dry for at least six weeks
prior to using the appliance in order to prevent cracks.
5.6 Placing the control hatch (if applicable)
The control hatch (also see paragraphs 5.4 and 5.5) is placed as low as possible in the chimney breast.
!Caution - The bottom of the control hatch may not be placed higher in the appliance than the burner surface.
- Place control hatch and bracket with gas control and accessories indoors in a dry place only!
A number of components are placed in the control hatch, such as data plate, gas control, receiver belonging to the
remote control and, if applicable, the control panel of the DRU Maxvent system ®or the components belonging to
the DRU Powervent system
®.

Ø Make an opening in the chimney breast of 285 x 194 mm (h x w).
Ø Place the inner frame (1); unscrew bolts (5) for this.
!Tip - When the chimney breast is made of bricks, the inner frame can be built with bricks at the same time
- When using a different material, you can glue the inner frame or fix it with four flush screws.
Ø Mount the gas control to the brackets of the inner frame (2).
Ø Reconnect the pipes to the gas control.
!Caution - Avoid kinks in the pipes;
- Tighten the flexible gas pipe and the pilot burner pipe until they are gastight.
- First tighten the thermocouple by hand and;
- Then tighten it a quarter turn using a suitable spanner;
- The pilot burner pipe must be protected against possible corrosive influences as a result of, for example,
humidity, cement that has fallen down, dirt that has fallen down from the chimney, etc. The pilot burner pipe
should remain permanently free from the ground and the walls of the room in which the appliance is built in.
When installing in an existing fireplace, or if it is not possible to keep the pipes free, the pipe should be
protected against corrosion by means of a jacket.
Ø Make sure there is no dirt in gas pipes and connections.

5.7 Flue gas discharge system in appliances with open combustion
For connection to an existing chimney without a discharge pipe or flexible SS discharge – only allowed in Great
Britain – the instructions provided in the separately supplied booklet 'Fitting into a conventional class 1 chimney'
apply. In addition to the installation instructions, this booklet also contains supplementary tests.
5.7.1 General
The appliance's type of discharge system is stated in Appendix 2, Table 2.
The appliance must be connected to an existing or newly built chimney, in accordance with the applicable
national, local and constructional (installation) regulations.
5.7.2 Connection of flue gas discharge system (if a class 1 chimney is not applicable)
At least a 3 metre discharge pipe or a flexible SS discharge should be connected to the appliance. Bends in the flue
gas discharge system are not allowed.
!Caution - 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 material all
around it;
- Use heat-resistant insulation material when passing through combustible material.
- Use a flue gas discharge system with the correct diameter, and which is provided with the CE mark.
!Caution Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell during
a longer period; these are not suitable.
Place the flue gas discharge system as follows:
Ø Connect the pipe pieces or flexible SS discharge.
Ø You should only install the appliance in a well ventilated room which complies with the applicable national, local
and constructional (installation) regulations, in order to guarantee sufficient air supply.
!Tip When the appliance is installed in a house with a mechanical air extraction system and/or an open kitchen with
cooker hood, you will need a permanent ventilation hole near the appliance; for this application, please observe
the gas installation regulations and the local instructions.
5.8 Flue gas discharge / combustion air supply system in appliances with closed
combustion
5.8.1 General
The appliance's type of discharge system is stated in Appendix 2, Table 2.
The appliance will be connected to a combined flue gas discharge / combustion air supply system, hereafter to be
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 5.8.4).
!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;
- For connecting to an existing chimney you should only use the chimney kit supplied by DRU.
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.
UK

English
INSTALLATION MANUAL
5.8.2 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 'Adjustment of the appliance' for the
method of working.
The concentric system with wall or roof terminal has to comply with the following conditions:
- First, a concentric pipe of minimum length should be connected vertically to the appliance, according to
Appendix 2, Table 4 or 5.
- 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. In that case, a 90° bend will be connected after the vertical part;
- 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. 4).
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
5.8.3 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
ceiling. If the system is built in (for instance) a cove, it should be made with non combustible material all
around it;
- Use heat-resistant insulation material when passing through combustible material;
- The rosette of the wall terminal is too small to seal the opening when passing through combustible material.
That is why you should first apply a sufficiently large heat-resistant intermediate sheet 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 a glue plate for a flat roof or with a universally adaptable tile for a sloping
roof.
!Caution Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell during
a longer period; 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 Attach the wall terminal from the outside by means of four screws.
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;
