Vent Clearances and Framing
B. Wall and Ceiling Penetration Framing
For a wall or ceiling penetration consult B-vent pipe manu-
facturer’s instructions to provide adequate clearances. 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.
C. Vertical Penetration Framing
WARNING! Fire Risk. 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.
