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).

‡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.

‡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).

‡,f wall thickness is less than 4-3/8 the e[isting heat shields must be field trimmed. ,f wall thickness is greater than 7-5/8 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.

• 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.

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.
