11 CHIMNEY, CONNECTING PIECE AND DAMPER
FLAP
Chimney
Chimney and connecting piece design must be in accordance with DIN 18160.1 or DIN EN 15287-1; di-
mensions must be calculated according to DIN EN 13384.
Connection of multiple fireplaces to the same chimney is possible, if there is proof that the chimney is suit-
able for this even if the design of these fireplaces is different (calculation of flow and thermal balance, and
approval from chimney sweep are necessary). However, it is not possible for fireplaces for use with open
doors. Please note, that a separate chimney connection is required in this case.
A soot fire resistant chimney of T400 type is necessary for safe operation.
Connecting piece
The smoke pipe (connecting piece) for chimney connection must be a suitable pipe according to DIN EN
1856-2 with CE marking.
The connecting piece must be connected directly to the chimney.
When the connecting piece is led through components from flammable building materials, e.g. through
protected walls, the connecting piece must be wrapped with insulation material of indicated thickness,
and around this thermal insulation, mineral non-flammable building materials must be used in a circumfer-
ence of 20 cm (approx. 8 inches). The connecting piece in the area of active back ventilation must be also
wrapped with a suitable insulation material to a thickness of at least 3 cm (approx. 1.2 inch).
Provide a suitable opening for measurements and revision in the chimney entrance area.
All smoke pipe joints must be sealed tight!
Damper flap
It is recommended to install a flue limiting device in the smoke pipe connecting piece.
The flap must be easy to operate and the position of the flap must be recognizable from outside by looking
at the handle. The flap must retain its desired position and cannot close by it self.
The damper flap must have openings, which are not less than 3 % of the cross-sectional area, but at least
20 cm² wide.
