Adjust the height of the appliance;
➠
Using a spirit level to ensure it is absolutely level.
N.B.
- Do not install the appliance fl at against the back
wall;
- Leave the space between the feet free;
- Do not cover and/or pack the appliance with an in-
sulating blanket or any other material.
➠
Secure the appliance against the wall using the wall
brackets and rawplugs supplied (see
Fig. 3
).
6.5 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 sec-
tion 6.5.3).
If necessary, you can also use an existing discharge
channel (see section 6.5.4).
N.B.
- Only use the concentric system supplied by DRU
(Ø100 / Ø150 mm). This system was tested in com-
bination 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.
The concentric system is constructed from (the di-
scharge stump of) the appliance.
If structural circumstances require that the concen-
tric system is placed fi rst, the appliance can later be
connected with a telescopic pipe piece.
6.5.2 Application with wall duct
6.5.2.1 Construction of concentric system with
wall duct
The concentric system with wall duct has to comply
with the following conditions:
➠
First, a concentric pipe of at least 1 meter should be connected vertically to the appliance;
➠
The total vertical pipe length can have a maximum of 4 meters;
➠
After the vertical part a bend of 90° is connected;
➠
When using a minimum 1 up to maximum 4 meter vertical pipe length, the total horizontal pipe length may have a
maximum of 3 meters (wall duct not included; see
Fig. 4a
).
Depending on the construction of the concentric system, further adjustments should be made to the appliance.
The next 2 confi gurations are allowed for the construction:
1) a minimum 1 meter up to maximum 4 meter vertical pipe length in combination with a 90° bend and a wall duct (i.e.
no horizontal part; see
Fig. 4b
).
- When using this confi guration, you must not remove the air inlet guides;
- When using this confi guration, you must not set the restriction.
2) a minimum 1 meter and maximum 4 meter vertical pipe length in combination with a 90° bend and a maximum
3 meter horizontal pipe length and a wall duct (see
Fig. 4a
).
- When using this confi guration you must remove the air inlet guides (see section 6.8);
- When using this confi guration, you must not set the restriction.
