D. Installing Heat Shield and Horizontal Termination Cap

WARNING

Fire Hazard

Impaired performance of appliance

•Telescoping flue section of termination cap MUST be used when connecting pipe section to termination cap.

•Maintain a 1-1/2 inch minimum overlap on telescoping flue section of termination cap.

Installing the Horizontal Termination Cap

Vent termination must not be recessed in the wall. Siding may be brought to the edge of the cap base.

Flash and seal as appropriate for siding material at outside edges of cap.

When installing a horizontal termination cap, follow the cap location guidelines as prescribed by current ANSI Z223.1 and CAN/CGA-B149installation codes.

WARNING

Fire Risk

Exhaust Fumes Risk

Impaired Performance of Appliance

•Overlap pipe slip sections at least 1-1/2 inches.

•Use pilot holes for screws.

•Screws must not exceed 1 inch long.

•Pipe may separate if not properly joined.

WARNING

Burn Risk

• Local codes may require installation of a cap shield to prevent anything or anyone from touching the hot cap.

Note: Where required, an exterior wall flashing is available.

When penetrating a brick wall, a brick extension kit is available for framing the brick.

Heat Shield Requirements for Horizontal Termination

For all horizontally vented appliances, a heat shield MUST be placed one inch above the top of the vent between the wall shield firestop and the base of the termination cap.

There are two sections of the heat shield. One section is factory-attached to the wall shield firestop. The other section is factory-attached to the cap. See Figure 8.13.

If the wall thickness does not allow the required 1-1/2 inch (38 mm) heat shield overlap when installed, an extended

SHEATHING

Important Notice: Heat shields may not be field constructed.

The extended heat shield (DVP-HSM-B) may need to be cut to length. You will attach the cut heat shield to the existing cap heat shield or wall shield firestop heat shield (refer to Figure 8.13) using the supplied screws. You MUST maintain a 1-1/2 in. (38 mm) overlap of the extended heat shield and the existing shields (both ends of the heat shield). The small leg on the extended heat shield should rest on the top of the vent (pipe section) to properly space it from the pipe section.
