The chimney must be cleaned yearly. This cleaning must take place in compliance with applicable
local legislation.
Chimney tips
The stove can be connected directly to the chimney.
The diameter of the outlet pipe must match the
diameter of the connector pipe on the fireplace.
We can guarantee that the appliance will work well if
there is a hearth draught of between 12 and 20 Pa.
The hearth draught can only be determined when the
appliance is lit! If the chimney draws too strongly, then
a damper must be incorporated.
If it draws too little, then the following measures should
be considered:
•
Extending the chimney
•
Improving the insulation of the chimney (less
cooling of the flue gases)
•
Improving the flow of air into the space in
which the stove is installed.
•
Improving the airtightness of the chimney.
Many problems with stoves are caused by badly working chimneys. Therefore we offer the
following tips. These are for information only and are not binding on us. There are just too many
unknown factors affecting how well the appliance-chimney combination works. If in doubt, you
should contact a specialist. Chimneys that have worked perfectly well with an old stove can give
problems with a new one. The stoves of 30 years ago had much lower performance than the
present generation of stoves which burn a lot cleaner and also have higher requirements as
regards the chimney.
Tips:
•
A round channel is preferable (to minimise friction)
•
The diameter of the chimney must not be smaller at any point than that of the appliance
(except in very long chimneys where a narrower section should sometimes be included).
•
The mouth of the chimney should be unobstructed.
•
The chimney should be as close as possible to vertical with as few curves as possible.
•
The chimney must not draw in extra air. Watch out for flue dampers and cleaning hatches
in the cellar or on the roof!
•
The chimney must not have too many connections - that reduces the upwards pressure.
Consult your chimney specialist!
•
Flue connections to different stoves and fireplaces must not be located opposite each
other at the same height, in order to prevent the chance that combustion gases will not be
drawn out. Two flue connections must be at separated vertically by at least 30 cm.

For the chimney opening, you will need to comply with your national legislation. For
Belgium this is NBN 61-001. Here are a few rules from this standard that cover chimney
openings:
