wall thimble will conceal it (see left image in

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 26).
NOTES:
• The four wood screws provided should be replaced
with the appropriate fasteners for stucco, brick,
concrete, or other types of siding.
• For buildings with vinyl siding, a vinyl siding
standoff, should be installed between the vent cap
and the exterior wall (see Figure 27). 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 27), so that an air space will
exist between the wall and the vent termination.
• 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.
• 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.
• When installing a vent pipe in a chase the minimum
clearance to combustibles is 2” (5 cm).

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.
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.
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 of the sheet metal straps back towards the vent cap, so the decorative
