The chimney, the flue and the air ducts should meet construction standards and
rules. The diameter of the hole of the chimney should be at least Ø150 mm.
The fireplace must be connected to a separate chimney; no other appliances may
be connected to the chimney.
The minimum chimney draught is 10 Pa. In case the chimney draught is too strong, it is
possible to install a smoke damper or a draught regulator. It can be installed in the flue, in
the chimney or in the heating wall.
Recommended minimum height of the chimney is 5 m from the fireplace. The chimney
must be higher than the highest point of the roof.
A cleaning hole should be projected in the chimney. It is recommended to clean the
chimney and the flue before the heating season and every 3 months thereafter.
It is recommended to install stainless steel liners that protect the chimney against
harmful effect of condensate humidity and the emitted smoke.
The flue connecting the fireplace and the chimney should be as short as possible and should
ascend towards the chimney. The maximum recommended horizontal length of the flue is
1m.
In order to connect the flue to the brick chimney it is necessary to:
- Mark the place where the flue will be connected;
- Make the hole using appropriate tools; the hole should be slightly bigger than the
diameter of the flue;
- Insert the flue. Seal the gaps with a fireproof material, e.g. rock-wool or fiberglass
rope.

- With a help of pliers remove two lids covering the connection places of the unions;
- Purchase air duct connection unions, outer diameter of which is Ø100 mm;
