penetrate the
roof. Determine if
ceiling joists,
roof rafters or
other framing will
obstruct the
venting system.
You may wish
to relocate the
appliance or to
offset, as
shown in dia-
gram 9 to avoid
cutting load
bearing members.
3) To install the Round Support Box/Wall Thim-
ble in a flat ceiling, cut a 10 inch square hole
in the ceiling centered on the hole drilled in
Step 2. Frame the hole as shown in diagram

4) Attach the Vinyl Siding Standoff (if re-
quired) to the Horizontal Vent Termination,
but first run a bead of non-hardening mastic
around its outside edges, so as to make a
seal between vent cap and the standoff.
Install the Vinyl Siding Standoff (Part # 950)
between the vent cap and the exterior wall
and attach with the four wood screws
provided. Seal around the Vinyl Siding
Standoff on all four sides. Diagram 5. The
arrow on the vent cap should be point-
ing up. Insure that the 1-1/4" clearances to
combustible materials are maintained. See
diagram 5.
Note: If installing termination on a siding
covered wall, a vinyl siding stand-
off or furring strips must be used
to ensure that the termination is
not recessed into the siding. The
four wood screws provided
should be replaced with appropri-
ate fasteners for stucco, brick,
concrete, or other types of sid-
ings.
5) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
black decorative wall thimble cover over
the vent pipe, then slide the Wall Thimble
(Part # 942) over the vent pipe.
6) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipe into the vent cap assembly. It is impor-
tant that the vent pipe extends into the vent
cap a sufficient distance so as to result in
a minimum pipe overlap of 1-1/4 inches.
Secure the connection between 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. Bend any remaining portion of the
sheet metal strip back towards the vent
cap, so it will be concealed by the decora-
tive wall thimble cover. See diagram 6.
7) Install Wall Thimble in the center of the 10"
square and attach with wood screws (in
Canada).
8) Slide the decorative wall thimble up to the
wall surface being careful not to scratch
the paint and attach with screws provided.
Apply decorative brass or chrome trim if
desired. See diagram 7.
1) Maintain the 1-1/4" clearanc-
es (air spaces) to combusti-
bles when passing through
ceilings, walls, roofs, enclo-
sures, attic rafter, or other
nearby combustible surfac-
es.
Do not pack air spaces with
insulation. Check page 13 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 loca-
tion where the vent will pen-
etrate 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 vent will
Diagram 11: 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.
4) Assemble the desired lengths of black pipe
and elbows necessary to reach from the
appliance adaptor up though the Round
Support Box. 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 com-
bustibles of 1-1/4". Slip the flashing under
the shingles (shingles should overlap half
the flashing) as per diagram 11.
6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is impor-
