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 sufficient distance with a

minimum of 11⁄4” (3.2cm) 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 wall

thimble will conceal it (see left image in Figure 30).

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 30).

NOTES:
(a) The four (4) wood screws provided should be replaced with the appropriate fasteners for stucco,

brick, concrete, or other types of siding.
(b) For buildings with vinyl siding, a vinyl siding standoff, should be installed between the vent cap and

the exterior wall (see Figure 31). 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 flat portion of the vinyl siding standoff (shaded area in Figure

31), so that an air space will exist between the wall and the vent termination.
(c) The horizontal run of vent pipe must be level and should have a 1⁄4 inch (6mm) rise for every

one foot (305mm) of run towards the termination. Never allow the vent to run downward. This

could cause high temperature and may present the possibility of a fire.
(d) The location of the horizontal vent termination on the exterior wall must not be easily blocked or

obstructed. Refer to I

(e) When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).
