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 overheating and fire.

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

‡DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184 mm) thick.

‡,f wall thickness is less than 4 in. the e[isting heat shields must be field trimmed. ,f wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.

‡,f wall thickness is less than 4-3/8 the e[isting heat shields must be field trimmed. ,f wall thickness is greater than 7-/8 in. a DVP-HSM-B will be required.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by non-com- bustible materials such as concrete, a hole with diameter one inch 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.

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.

•DVP pipe - A wall shield firestop is required on one side only on interior walls. If your local inspector requires a wall shield firestop on both sides, then both wall shield firestops must have a heat shield (refer to Section 16.B.) attached to them.

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