Hearth and Home Technologies ST-550TM-IPI owner manual Install Horizontal Termination Cap

L. 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 and HRC caps are 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.
