The following components are taken
into consideration for the maximum flue
lengths:
■ Connection pipe 0.5 m long
■ 1 flue bend 87° and 1 support bend
87°
or
■ 2 flue bends 45° and 1 support bend
87°
Subtract other bends, tees and straight
lengths from the maximum length using
the following values:
■ Connection pipe 0.5 m long: 0.5 m
■ Connection pipe 1 m long: 1 m
■ Flue bend 45°: 0.3 m
■ Flue bend 87°: 0.5 m
■ Inspection tee: 0.3 m
Installation
Danger
To ensure correct function, route
the flexible flue at a maximum
angle of 45° from the vertical.
Never pull the flexible flue pipe
over sharp edges during instal-
lation.
Note:
■ Always draw the flue pipe in from the
top downwards.
■ Observe flow direction (arrow on
components).
■ Subject to shaft size, install spacers
at intervals of max. 2 m.
■ Insert a spacer before and after any
change in direction and any inspec-
tion piece.
■ The flue must not come into contact
with the shaft wall.
