3.28.9 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
Flat roof
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. 13.
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.
3.29.10 Installing flue piping sections for both
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.
