Step 3.

For installations using a round support box/wall thimble (check pipe manufacturer's instructions), mark the wall for a 10 in. x 10 in. (254mm x 254mm) square hole. The center of the square hole should line up with the center line of the horizontal pipe, as shown in Figure 5.5. Cut and frame the hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustible material, i.e. masonry block or concrete, a 7 in. (178mm) diameter hole is acceptable.

NOTE:

(1) Installation requires a minimum of 11 in. (279mm)

horizontal run. Each 1 ft. (305mm) of horizontal vent

run must include a 1/4 in. (6mm) of vertical rise towards

the termination. Never allow the vent to run downward.

This could cause high temperatures and may present

the possibility of a house or structure fire.

(2) The location of the horizontal vent termination on an

exterior wall must meet all local and national building

codes, and must not be easily blocked or obstructed,

see Figure 4.4 on page 9.

(3) For installations requiring a vertical rise on the exterior

of the building, a snorkel kit is available with a 14 in.

(356mm) and a 36 in. (914mm) tall snorkel termination

cap. Follow the same installation procedures as used

for standard horizontal terminations. If the snorkel

termination must be installed below grade (i.e. basement

application), proper drainage must be provided to

prevent water from entering the snorkel termination. Do

not backfill around snorkel termination.

Step 4.

Position the horizontal termination cap in the center of the 10 in. x 10 in. (254mm x 254mm) square hole and run a bead of non-hardening mastic around its outside edges, so as to make a seal between it and the wall, attach termination cap to the exterior wall with the four wood screws provided.

When installing the Sapphire in a rear vent configuration with no vertical rise: a Snorkel Kit must be used, and a derating orifice must be installed. The appropriate orifice is supplied with the Rear Vent Kit.

other types of sidings.

(2) A termination cap with a built-in vinyl siding standoff is

highly recommended on a building with vinyl siding. The

pilot hole will be 2 in. (51mm) closer to the bottom of the

square than the top. Using a framing square, draw a 14

in. x 14 in. (356mm x 356mm) square around the pilot

hole in the siding. See Figure 5.7 on the next page.
