Many problems with inset fires are caused by badly working chimneys. Therefore some suggestions:

A round channel is preferred (minimum friction)

The diameter of the chimney may 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 may not have too many connections - that reduces the upwards pressure. Consult your chimney
specialist!

Flue connections to different inset fires and fireplaces may 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.
