VENTING
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.
