Note:
a) The horizontal run of vent should have a
1/4 inch rise for every 1 foot of run towards
the termination. Never allow the vent to run
downward. This could cause high tempera-
tures and may present the possibility of a
fire.
b) The location of the horizontal vent termina-
tion on an exterior wall must meet all local
and national building codes, and must not
be blocked or obstructed. See diagram in the
"External Vent Terminal Locations" section.
4) If installing the vent termination to a wall with
vinyl siding, the Vinyl Siding Standoff must be
used. Attach the Vinyl Siding Standoff 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) between the vent cap and the exte-
rior wall and attach with the four wood screws
provided. Seal around the Vinyl Siding Standoff
on all four sides. Diagram 6. The arrow on the
vent cap should be pointing up. Insure that
the 1-1/4" clearances to combustible materials
are maintained. See diagram 4.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff 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 appropriate
fasteners for stucco, brick, concrete, or
other types of sidings.
5) Before connecting the horizontal run of vent pipe
to the vent termination, slide the black decora-

tive wall thimble cover over the vent pipe, then
slide the Wall Thimble over the vent pipe.
6) Slide the appliance and vent assembly towards
the wall carefully inserting the vent pipe into
the vent cap assembly. It is important 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 extend-
ing 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. Bend any remaining portion of the sheet
metal strip back towards the vent cap, so it will
be concealed by the decorative wall thimble
cover. See Diagram 5.
7) Install wall thimble in the center of the 10"
square and attach with wood screws.
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
6.

1) Maintain the 1-1/4" clearances (air spaces)
to combustibles when passing through ceil-
ings, walls, roofs, enclosures, attic rafter, or
other nearby combustible surfaces. Do not
pack air spaces with insulation. Check the
"Exterior Vent Terminal Locations" section
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 ceil-
ing. 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 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 Diagram 8 to avoid cutting load bearing
members.
