of the sheet metal straps back towards the
vent cap, so the decorative wall thimble will
conceal it (see left image in Figure 10).
STEP 7. Slide the decorative wall thimble up to the
wall surface and attach with the screws
provided. Apply decorative brass or chrome
trim if desired (see right image in Figure 10).
NOTES:
(1) The four wood screws provided should be replaced
with the appropriate fasteners for stucco, brick,
concrete, or other types of siding.
(2) For buildings with vinyl siding, a vinyl siding
standoff, should be installed between the vent cap
and the exterior wall (see Figure 11). Attach the
vinyl siding standoff to the horizontal termination.
The vinyl siding standoff prevents excessive heat
from possibly melting the vinyl siding material.
Note that the horizontal vent termination bolts
onto the at portion of the vinyl siding standoff
(shaded area in Figure 11), so that an air space will
exist between the wall and the vent termination.
NOTES:
(1) The horizontal run of vent pipe must be level and
should have a inch rise for every one foot
of run towards the termination. Never allow
the vent to run downward. This could cause high
temperature and may present the possibility of a
re.
(2) The location of the horizontal vent termination
on the exterior wall must not be easily blocked
or obstructed. Refer to “Initial Installation - Vent
Termination Restrictions” section.
(3) When installing a vent pipe in a chase the minimum
clearance to combustibles is 2” (5 cm).

STEP 4. Position the horizontal vent termination in the center of the 10” (25.4 cm) x 10” (25.4 cm) hole, and attach
to the exterior wall with the four screws provided. Before attaching the vent termination to the exterior
wall, run a bead of non-hardening mastic around the edges, so as to make a seal between the termination
and the wall. The arrow on the vent termination should be pointing up, insure that the proper clearances
to combustible materials are maintained.
STEP 5. Before connecting the horizontal run of the vent pipe to the vent termination, slide the black decorative
wall thimble cover over the vent pipe.
STEP 6. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the cap
assembly. It is important that the vent pipe extend into the vent cap a sufcient distance with a minimum
of 1” (3.2 cm) overlap. Secure the connection between the vent cap pipe and the vent cap by attaching
the two sheet metal straps extending from the vent cap assembly into the outer wall of the vent pipe. Use
the two sheet metal screws provided to connect the straps to the vent pipe. Bend any remaining portion
