Galvanized pipe is desirable above the roofline
due to its higher corrosion resistance. Continue
to add pipe sections through the flashing until the
height of the flue cap meets the minimum height
requirements specified in local codes. Note that
for steep roof pitches, the vertical height must be
increased.
A poor draft, or down drafting can result from high
wind conditions near big trees or adjoining roof
lines, in these cases, increasing the flue height
may solve the problem. Maximum height is 6.7
meters.

5. Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The hole
should be of sufficient size to meet the minimum
requirements for clearance to combustibles of
50mm.
6. Continue to assemble pipe lengths.

• A clearance of 50mm must be maintained.
We recommend framing a 279mm x
279mm (inside dimensions) hole to
give structural rigidity for mounting the
termination.
1. Do not pack air spaces with insulation.
Check "Flueing Arrangement - Ver tical
Termination" section for the maximum
vertical rise of the flueing system and the
maximum horizontal offset limitations.
2. Set the gas appliance in
its desired location. Drop a
plumb bob down from the
ceiling to the position of the
appliance flue exit, and mark
the location where the flue
will penetrate the ceiling.
Drill a small hole at his point.
Next, drop a plumb bob from
the roof to the hole previously
drilled in the ceiling, and
mark the spot where the
flue will penetrate the roof.
Determine if ceiling joists,
roof rafters or other framing
will obstruct the flueing
system. You may wish to
relocate the appliance or to
offset, as shown in Diagram
2 to avoid cutting load bearing members.
3. Cut a hole large enough to allow for proper
clearances and or large enough for heat to
escape cavity. .
4. Assemble the desired lengths of pipe
and elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked position
and sealed.

• For best results and optimum performance
with each approved flueing system, “Mill-
Pac” sealant to every inner pipe connection.
Failure to do so may result in drafting or
performance issues not covered under
warranty.
NO
TE
• If an offset is necessary in the roof
space to avoid obstructions, it is impor-
tant to support the flue pipe every 0.9
meter, to avoid excessive stress on the
elbows, and possible separation. Metal
Wall straps can be used (diagram 2).
Do not combine flueing components
from other manufacturers.
NO
TE
• Any closets or storage spaces, which the
flue passes through must be enclosed.
