C. 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.

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.

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 8.12.

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.

NOTE: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).

The heat shield is designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184 mm) thick. If wall thickness is less than 4 in. (102

mm)the existing heat shields must be field trimmed. If wall thickness is greater than 7-1/4 in. (184 mm) a DVP-HSM-B will be required.

SHEATHING

(38 mm) heat shield overlap when installed, an extended heat shield (DVP-HSM-B) must be used.

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 8.12) 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.

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.

DVP-HPC2 can adjust 4-1/8 in. (6-3/8 to 10-1/2)

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