Install Vertical Termination Cap | Heatiator HEIR42T, HEIR42H

F. Install Vertical Termination Cap

•Attach the vertical termination cap by sliding the inner collar of the cap into the inner ﬂue of the pipe section while placing the outer collar of the cap over the outer ﬂue of the pipe section.

•Secure the cap by driving three self-tapping screws (supplied) through the pilot holes in the outer collar of the cap into the outer ﬂue of the pipe (see Figure 10.13).

G.Heat Shield Requirements for Horizontal Termination

WARNING! Risk of Fire! To prevent overheating and ﬁre, heat shields must extend through the entire wall thick- ness.

•DO NOT remove the heat shields attached to the wall shield ﬁrestop and the horizontal termination cap shown in Figure 10.14.

•Heat shields must overlap 1-1/2 in. (38 mm) mini- mum.

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 10.20.

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

•If the wall thickness is less than 4 in./102 mm (DVP), the heat shields on the cap and wall shield ﬁrestop must be trimmed. A minimum 1-1/2 in. (38 mm) overlap MUST be maintained.

•Use an extended heat shield if the ﬁnished wall thickness is greater than 7-1/4 in. (184 mm).

•The extended heat shield may need to be cut to length maintaining sufﬁcient length for a 1-1/2 in. (38 mm) overlap between heat shields.

•Attach the extended heat shield to either of the existing heat shields using the screws supplied with the extended heat shield. Refer to vent components diagrams in the back of this manual.

•Rest the small leg on the extended heat shield on top of the pipe section to properly space it from the pipe section.

Important Notice: Heat shields may not be ﬁeld constructed.

H. Install Horizontal Termination Cap

WARNING! Risk of Fire! The telescoping ﬂue section of the termination cap MUST be used when connecting vent.

•1-1/2 (38 mm) minimum overlap of ﬂue telescoping section is required.

Failure to maintain overlap may cause overheating and ﬁre.

•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 and refer to Section 6 of this manual.

CAUTION! Risk of Burns! Local codes may require in- stallation of a cap shield to prevent anything or anyone from touching the hot cap.

NOTICE: For certain exposures which require superior resistance to wind-driven rain penetration, a ﬂashing kit is available. When penetrating a brick wall, a brick extension kit is available for framing the brick.

Note: When using termination caps with factory-supplied heat shield attached, no additional wall shield ﬁrestop is required on the exterior side of a combustible wall.
