Heat & Glo LifeStyle SL-950TV-IPI-E Vent Clearances and Framing, C. Vertical Penetration Framing

8 Vent Clearances and Framing

A. Pipe Clearances to Combustibles

Vent clearances are per vent manufacturer’s specifica- tions. MUST be Listed B-Vent pipe.

WARNING! Risk of Fire! Maintain air space clearance to vent. DO NOT pack insulation or other combustibles:

•Between ceiling firestops

•Between wall shield firestops

•Around vent system

Failure to keep insulation or other material away from vent pipe may cause over heating and fire.

B. Wall and Ceiling Penetration Framing

For a wall or ceiling penetration consult B-vent pipe manufacturer’s instructions to provide adequate clear- ances. Use same size framing materials as those used in the wall or ceiling construction. Firestop spacers must be used in wall and ceiling penetrations per the B-Vent pipe manufacturer’s specifications and national, regional and local codes.

Note: MUST terminate vertically.

WARNING! Risk of Fire! DO NOT allow loose materials or insulation to touch vent. Hearth & Home Technologies Inc. requires the use of an attic shield.

The National Fuel Gas Code ANSI Z223.1 and NFPA 54 requires an attic shield constructed of 26 gauge minimum metal that extends at least 2 in. (51 mm) above insulation.

Attic shields must meet specified clearance and be se- cured in place.

Use B-vent manufacturer’s firestops to provide adequate clearances.
