IMPORTANT:
– Each additional 90° curve installed reduces the avai-
lable length by 1.0 metres.
– Each additional 45° curve installed reduces the avai-
lable length by 0.80 metres.
– The insertion of the condensation collector (8) is
obligatory in C32 discharge type.

The maximum flue legnth is determined
by the sum of the individual head losses
of the air inlet and exhaust components
and must not exceed 9.5 mm H2O (93.2
Pa). For the individual head loss of the
