UNIT INSTALLATION WITH
VERTICAL
TERMINATION
102MM X 175MM FLUEING
(Rigid Flue Systems)
1) Maintain the 50mm 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 "Flueing" Sections for
the maximum vertical rise of
the venting 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 vent will penetrate the
ceiling. Drill a small hole
at this point. Next, drop a
plumb bob from the roof to
the hole previously drilled
in the ceiling, and mark the
spot where the vent will penetrate the roof.
3) Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow con-
nections are in the fully twist-locked position
and sealed.
Note: All vertical terminations are vented
using 102mm x 168mm venting and Simp-
son Duravent only.

4) 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.
Note: 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.
5) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is important
to support the vent pipe every 0.9
metre, to avoid excessive stress on
the elbows, and possible separation.
Metal Wall straps can be used. Do not

combine flueing components from other
manufacturers.
Galvanized pipe is desirable above the roof space
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
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.
6) Ensure vent 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.
