8 Vent Clearances and Framing

A. Pipe Clearances to Combustibles

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.

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

•SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to 194 mm thick).

•If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed. If wall thickness is greater than 7-5/8 in. a DVP- HSM-B will be required.

B. Wall Penetration Framing

Combustible Wall Penetration

Whenever a combustible wall is penetrated, you must frame a hole for the wall shield ﬁrestop(s). The wall shield ﬁrestop maintains minimum clearances and prevents cold air inﬁltration.

•The opening must be framed on all four sides using the same size framing materials as those used in the wall construction.

•SLP pipe - A wall shield ﬁrestop must be placed on each side of an interior wall. A minimum 1-1/2 in. (38 mm) overlap of attached heat shields must be maintained.

•See Section 10.L. for information for regarding the in- stallation of a horizontal termination cap.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by noncom- bustible materials such as concrete, a hole with diameter one in. greater than the pipe is acceptable.

Whenever a non-combustible wall is penetrated, the wall shield ﬁrestop is only required on one side and no heat shield is necessary.
