Installation
requirements

General

The appliance must be connected tightly to a well-
functioning chimney.
For the connection measurements: see the
appendix "Technical data".
Ask the fire brigade and/or your insurance
company about any specific requirements and
regulations.

Flue or chimney

The flue or chimney is needed for:
Disposing of the combustion gases through natural
draught.
The warm air in the flue or chimney is lighter
than the outside air so it rises.
The intake of air, 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.
Ask your installer for advice regarding the flue. Refer
to the European norm EN13384 for a correct
calculation 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
Subject to change because of technical improvements

Installation requirements

horizontal pieces disrupt the outward flow of
combustion gases and may cause the deposit of
soot.
The interior measurements should not be too big, to
prevent the combustion gases from cooling down
too much, thereby reducing the draught.
The flue or chimney must ideally have the same
diameter as the connection collar.
For the nominal diameter: see the appendix
"Technical data". If the smoke channel is well
insulated, 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)
narrower segments disrupt the outward flow of
combustion gases.
When using a cover plate or exhaust hood : make
sure that the cover does not restrict the flue outlet
and that the cap does not impede the outward flow
of combustion gases.
The chimney must end in a zone that is not
affected by surrounding buildings, adjacent trees or
other obstacles.
The chimney part outside the house must be
insulated.
The chimney must 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 away
from the flue: stick to the measurements in the
following figure. A = the highest point of the roof
within a distance of 3 metres.
