Place other end of EPDM connection gasket to
flue output terminal. Pay attention to correct
placement of gaskets:
• Click-fit gasket for concentric extension pipes
and bends. In order to connect possible
extension connections of exhaust gas flues
with other elements of flues: Connect from
concentric pipe or concentric bend male
part (flat) to female part of the previous
piece (gasket side), in such case ensure that
required stamp is placed, therefore the piece
maintaining tightness and the set shall be
combined.
When it is required to shorten the
discharge flue and/or extension,
consider that internal pipe should
protrude 5 mm when compared with the external
pipe.
For security purposes, combi suction /
discharge flue should not blocked even
temporarily.

Total length of hermetic flue set should not exceed 10 m with single bend horizontally. Also, this total
length reduces by 1 m with every 90°bends or two 45° bends. Maximum 3 pieces of 90° bend can be used.

During installation of horizontal
pipes, the pipe slope should be
kept at 3% upwards as minimum
and dowel at every 3 meters and holder
clamps should be used.
