FLUEING INFORMATION
90° elbow 45° bend Elbows and bends create resistance within the venting
configuration, and they must be included when determining
the minimum and maximum fluing lengths. There must
be an absolute minimum vertical rise of 600 mm before
any elbow but preferably a vertical rise of 900 mm is
recommended. Maintain the maximum length of straight
flue between elbows or bends.
The use of a 90° elbow is equal to 0.5 metres in flue length
and the 45° bend is equal to 0.25 metres in flue length i.e.,
if one 90° elbow is used then the total maximum flue length
is reduced to 5.5 metres.
No more than two (2) 90° elbows or four (4) 45° bends can
be used in the flue configuration.
Termination cap. The same basic termination (cowl) cap
is used for both vertical and horizontal installations.
For the vertical installation the terminal is fitted with a wind
guard. For horizontal installation the terminal is not fitted
with a wind guard.
