➠
Determine the location of the appliance; the dimen-
sions can be found in

.
➠
Provide a gas connection at the location. For details,
see section 6.3.
➠
Make a duct for the fl ue gas discharge/combustion
air supply system with the following diameters. For
details, see section 6.5 and
Fig. 5
.
-
Ø160 mm for a wall duct through incombustible
material;
-
Ø 250 mm for a wall duct through combustible
material;
-
Ø160 mm for a roof duct through incombustible
material;
-
Ø 250 mm for a roof duct through combustible
material.
Connect the appliance to the wall using the wall
bracket and the wedge bolts supplied; see

Flue gas discharge / combustion air supply system
6.5.1
General
The appliance is of the C11/C31 type.
The appliance is connected to a combined fl ue gas discharge/combustion air supply system, hereafter referred to
as the concentric system.
The passage to the outside can be made with a wall duct (see section 6.5.2) or with a roof duct (see section 6.5.3).
If necessary, you can also use an existing discharge channel (see section 6.5.4).
Caution:
-
Only use the concentric system supplied by DRU (Ø100 / Ø150
mm). This system was tested in combination with the
appliance;
DRU cannot guarantee a proper and safe operation of other systems and cannot accept liability for these systems.
For connecting to an existing chimney fl ue you should only use the installation set supplied by DRU.
Always place the concentric system at a minimum distance of 500 mm from combustible objects and/or materials
Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling.
If the system is built in (for instance) a cove, it should be made with incombustible material all around it.
The concentric system is constructed from (the discharge stump of) the appliance.
If structural circumstances require that the concentric system is placed fi rst, the appliance can later be connected
with a telescopic pipe piece.
!Tip
DRU does not recommend placing the telescopic piece, because this visible pipe piece cannot be supplied in colour
and does not really combine well with the appliance.
