5.2 The chimney
Before a stove is connected to a chimney, the size and quality of the chimney must be checked to
ensure that they meet locally applicable regulations. The measurements may need to be
calculated.
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 air tightness 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!
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:
