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 Diagram 5 or
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.
7. Ensure flue is vertical and secure the base of
the flashing to the roof with roofing rails, slide
storm collar over the pipe section and seal with
a mastic.
8. Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces,
which the flue passes through must
be enclosed.

Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature silicone
sealant to outer pipe on every twist-
lock joint.
Vertical Terminations
1)
Maintain the 32mm clearances (air spaces)
to combustibles when passing through
ceilings, walls, roofs, enclosures,
attic rafter, or other nearby
combustible surfaces. Do not
pack air spaces with insulation.
Check section"Simpson Dura-
vent Flueing" 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
a p p l i a n c e
or to offset,
as shown in
Diagram 2 to
avoid cutting
load bearing
members.
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.
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 38mm. Slip the flashing under the shingles
(shingles should overlap half the flashing) as
per Diagram 4.
Diagram: The upper half of the
fl
ashing is installed
under the roofing material and not nailed down
until the chimney is installed. This allows for small
adjustments.
6. Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is important
to support the flue pipe every metre,
to avoid excessive stress on the
elbows, and possible separation.
Wall straps are available for this
purpose (Diagram 2).
