Flue cowl clearance
To ensure products of combustion are cleared,
adequate clearance from the building is
required.
The flue cowl should have a 500 mm clearance
from any part of the building. This also applies
to steeped and pitched roofs where the flue
cowl should be 500 mm clear of the ridge line.
An adequate flow of fresh air must exist around
the flue cowl following installation.
Minimum clearances are shown in
AS/NS 5601.1
Shared flues
Gas appliances must not be connected to a
chimney or flue serving a separate flue burning
appliance.
Flashings
Flashings are not included in the flue kits. Flashings must comply with E2, this is the responsibility
of the installer.
Attaching the masonry colinear flexi flues to the flue adaptor box
The flexi flues need to be securely fixed to the colinear flue adapter.

Air intake flue (smaller flue LHS)
Attach the air intake flue over the spigot, place the clamp over the flue and tighten. Do NOT
over tighten as this will crush and damage the flue. Drill through the pre-punched holes either
side of the clamp, and into the spigot on the flue adaptor. Secure in place using the stainless
self taping screws provided, ensuring the connection will stop movement or dislodgement of
the flue.
•
Exhaust flue (larger flue RHS)
Slide the exhaust flue into the spigot and push down until it is clipped in place—there are barbs
either side to hold it in place.
