Enviro C-10450 owner manual Installing Horizontal Vent Termination

Initial Installation

QUALIFIED INSTALLERS ONLY

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 sufficient distance with a minimum of 11⁄4” (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 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. Figure 11: Installing Vent Cap with Vinyl Siding Stand-Off.

Note that the horizontal vent termination bolts onto the flat 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 1⁄4 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 fire.

(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).
