VENTING
GAS CONNECTION
Use only an approved B vent system.
An approved chimney liner must be
used.
It is recommended that the flue be
installed vertically only. If installation
prevents this then there must be at
least 4 feet of vertical flue before any
bends. The flue must not fall below
horizontal at any stage. There must
not be more than 2 bends in any
system. Any horizontal section of flue
must be less than 1/3 the length of
vertical flue which follows it.
See diagram
An approved B vent system must be
attached by mechanical means to the flue
spigot and sealed using an approved high
temperature sealant.
