The following components are taken into consideration for the maxi-
mum flue lengths:
■
Connection pipe D 0.5 m long.
■ 1 bend 87º and 1 support bend 87º
or
■ 2 bends 45º and 1 support bend 87º
Subtract other bends, tees and extension pieces from the maximum
length using the following values:
■ Connection pipe 0.5 m long: 0.5 m
■ Connection pipe 1 m long: 1 m
■ Bend 45º: 0.3 m
■ Bend 87º: 0.5 m
■ Inspection tee: 0.3 m
