outed vertically alongside the outside wall to above
the roofline. Special seals are required to prevent rainwater
penetrating the pipe joints.

where a room sealed flue installation is impractical. The kit comprises of a
flue adaptor from the appliance to the chimney, a flexible plastic flue liner
with connection parts and chimney terminal (see Figure 3f). Where an
open flue system is used, then an air vent must be provided in the same
room or internal space as the flue duct air inlet, see section 3.4.
For installation details refer to the flue kit instructions.
