UNIT INSTALLATION WITH
VERTICAL TERMINATION
102MM X 175MM FLUEING
(Rigid Flue Systems)
1. Maintain the 51mm 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 connections 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.
7. Install the vertical termination cap.
Note: Any closets or storage spaces, which the
vent passes through must be enclosed.
