Installation
requirements
General
The appliance must be connected tightly to a well-
functioning flue.
For connection measurements: see 'Technical
data' appendix.
Ask the fire service and/or your insurance com-
pany about any specific requirements and reg-
ulations.
Flue
The flue is needed for:
Removal of combustion gases via natural
draught.
As the warm air in the flue or chimney is
lighter than the outside air, it rises.
Air intake, needed for the combustion of fuel in the
appliance.
A poorly functioning flue or chimney can cause
smoke to escape into the room when the door is
opened. Damage caused by smoke emissions into
the room is not covered by the warranty.
Do not connect multiple appliances (such as a
boiler for central heating) to the same flue,
unless local or national regulations allow this.
In the event of two connections ensure that
the difference in height between the con-
nections is no less than 200 mm.
Ask your installer for advice regarding the flue. Refer
to the European norm EN13384 for a correct calcu-
lation for the flue.
The flue must satisfy the following requirements:
The flue or chimney must be made of fire-resistant
material, preferably ceramics or stainless steel.
The flue or chimney must be airtight and well
cleaned and guarantee sufficient draught.
A draught/vacuum of 15 - 20 Pa during normal
operation is ideal.

Starting from the flue spigot, the flue must run as
vertically as possible. Changes in direction and
horizontal pieces disrupt the outward flow of com-
bustion gases and may cause soot deposits.
To prevent combustion gases from cooling down
too much, which reduces the draught, ensure that
the interior diameter is not too big.
The flue or chimney should ideally have the same
diameter as the connection collar.
For nominal diameter: see 'Technical data'
appendix. If the smoke channel is well insu-
lated, the diameter may be slightly bigger (up
to 2x the section of the connection collar).
The section (area) of the smoke channel must be
constant. Wider segments and (in particular) nar-
rower segments disrupt the outward flow of com-
bustion gases.
In fitting a cover plate/exhaust cap to the flue:
make sure that the cover does not restrict the flue
outlet and that the cap does not impede the out-
ward flow of combustion gases.
The flue must end in a zone that is not affected by
surrounding buildings, trees or other obstacles.
The flue outside the house must be insulated.
The flue should be at least 4 metres high.
As a rule of thumb: 60 cm above the ridge of the
roof.
If the ridge of the roof is more than 3 metres from
the flue: use the measurements given in the fol-
lowing figure. A = the highest point of the roof
within a distance of 3 metres.
