5. Mark the wall with an 11” (279mm) x 10” (254mm) hole. See
termination framing on page 22. The center of the hole
should line up with the centerline of the horizontal pipe. Cut
and frame the 11” (279mm) x 10” (254mm) hole in the exte-
rior wall where the vent will be terminated. If the wall being
penetrated is constructed of non-combustible material, (i.e. a
masonry block, or concrete) a hole with zero clearance is
acceptable. NOTES: The horizontal run of vent must be
level, or have a 1/4” (6 mm) rise for every 12” (305 mm) of
run towards the termination. Never allow the vent to run
downward. This could cause high temperatures and may
present the possibility of a fire. ALSO: The location of the
horizontal vent termination on an exterior wall must meet
local and national building codes, and must not be blocked
or obstructed. For Allowable Termination Locations see page
12 in this manual.
6. Position the Horizontal Vent Termination in the center of the
square hole (arrow on the vent cap should be facing UP),
and run a bead of non-hardening sealant around the outside
edges of the termination, so as to make a seal between the
termination and the wall. Finish attaching the termination cap
to the wall with the four wood screws provided with the termi-
nation cap. NOTE: The four wood screws provided should be
replaced with the appropriate fasteners for stucco, brick, con-
crete or other types of siding. For buildings with VINYL SID-
ING, a Vinyl Siding Standoff should be installed between the
vent cap and the exterior wall. Attach the Vinyl Siding Stand-
off to the Horizontal Termination Cap by bolting the flat por-
tion of the Vinyl Siding Standoff (Fig.1.) so that an air space
will exist between the wall and the Vent Termination.
7. Locate and slide the Wall Thimble Cover over the vent pipe.
8. 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 extend into the vent cap suffi-
cient distance so as to result in a minimum pipe overlap of 1-
1/4” (31 mm). Secure the connection between the vent pipe
and the vent cap by attaching the two sheet metal strips ex-
tending from the vent cap assembly into the outer wall of the
vent pipe. Use the two sheet metal screws provided to con-
nect the strips to the pipe section. Bend any remaining por-
tion of the sheet metal strip back towards the vent cap, so it
will be concealed by the Wall Thimble Cover. (Fig. 2.)
9. Slide the Wall Thimble Cover up to the wall surface and at-
tach to the wall with wood screws. (Fig. 3.)
