the vent pipe and the vent cap by attaching
the two sheet metal strips extending from
the vent cap assembly into the outer wall
of the vent pipe. Use the two sheet metal
screws provided to connect the strips to the
pipe section. See Diagram 4.
9) Install wall thimble in the center of the
10" square and attach with wood screws
(Diagram 5).

Vertical Terminations

1) Maintain the 1-1/4" 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 the "Venting
Arrangement" section for the maximum
vertical rise of the venting system and the
maximum horizontal offset limitations.
2) Set the gas appliance in its desired lo-

cation. 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 his point. Next, drop
plumb bob from the roof to the
hole previously drilled in the ceil-
ing, and mark the spot where
the vent will penetrate the roof.
Determine if ceiling joists, roof raft-
ers or other framing will obstruct
the venting system. You may wish to
relocate the appliance or to offset, as
shown in Diagram 2 to avoid cutting
load bearing members.
3) A Firestop spacer must
be installed in the floor or
ceiling of every level. To
install the Firestop spacer
in a flat ceiling or wall, cut
10 inch square hole. Frame the hole as shown
in Diagram 3 and install the firestop.
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.

clearance to combustibles of 1-1/4". Slip the
flashing under the shingles (shingles should
overlap half the flashing) as per Diagram 4.
NOTE: For best results and optimum perfor-
mance with each approved venting system,
it is highly recommended to apply "Mill-Pac"
sealant (supplied) to every inner pipe connec-
tion. Failure to do so may result in drafting or
performance issues not covered under warranty.

6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is important
a
to support the vent pipe every 3 feet,
to avoid excessive stress on the
elbows, and possible separation.
Wall straps are available for this
purpose (Diagram 2).

Diagram 4: The upper half of the flashing is
installed under the roofing material and not
nailed down until the chimney is installed.
This allows for small adjustments.
Galvanized pipe is desirable above the roofline
due to its higher corrosion resistance. Continue
to add pipe sections through the flashing until
in
the height of the vent 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
o conditions near big trees or adjoining roof lines,

in these cases, increasing the vent height may
solve the problem.

7) 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.
