FLUE SYSTEMS
INSTALLING THE VERTICAL FLUE
TERMINAL
2. Vertical Flue Terminal (Through the Roof)
a) Determine the exact location where the roof flue
terminal will exit the roof, ensuring the flue system
clears all obstructions. For pitched roofs, the flue cap
must be the distance above the roof line as specified
(300mm to base of Flue Clamp, minimum). The top of
the roof terminal may extend up to 760mm (2.5ft)
above the roof line as required.
b) Run the concentric flue system to the proper distance
below the roof sheathing required for the correct
distance of the roof terminal above the roof surface.
See the following sections on installing the rest of the

flue system.

c) Cut a minimum 165mm (6.5in) diameter hole for the
flue centred in the desired location for the roof
terminal, see Fig. 6.
d) Centre the roof flashing over the hole using either the
flat roof flashing or universal flashing for pitched roofs.
e) Slip the storm collar supplied with the roof flashing kit
over the outside of the flue terminal and align with the
flue pipe end below roof opening. Insert the terminal
into the flue pipe.
f) Fasten the roof flashing with nails. Seal the flue
terminal and flashing to the roof.
g) Install the gasketed clamp around the joint between
the flue terminal and flue pipe.

INSTALLING FLUE PIPING SECTIONS
FOR BOTH APPLICATIONS
a) The coaxial flue pipe sections are designed to fit
tightly together and seal with the integral flue pipe seal
and supplied pipe clamps. No silicone caulk or special
tools are required.
b) All flue sections and fittings come complete with
silicone flue pipe gaskets and outside gasketed pipe
clamps for making air tight connections between the
flue pipe connections.
c) Raise the flue pipe to the flue terminal connection with
the gasketed end of the flue pipe towards the flue
terminal. Insert the flue pipe into the flue terminal
connection and grasp the end of the flue pipe while
twisting and pushing the pipe until inserted all the way
into the flue terminal.
d) Connect the outside pipes together using the
gasketed clamps provided. The flue pipes have ribs
located near each end. When the flue piping is
connected, the gasketed clamps shall cover the ribs
and joints of the connecting flue tubes. Support each
pipe section with hangers attached to the supporting
joints in the wall or ceiling.
e) Continue connecting pipe sections together with
clamps and supporting with hangers.
