WARNING! Risk of Fire!
Maintain air space clearance to

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.

B. wall Penetration Framing/Firestops
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 7.F. for information for regarding the
installation of a horizontal termination cap.
Non-Combustible wall Penetration
If the hole being penetrated is surrounded by non-
combustible 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.
* When using SLP pipe, minimum clearances from the vent pipe to combustible
materials at inside wall firestops are:
Top: 2-1/2 in. (64 mm)
Bottom: 1/2 in. (13 mm)
Sides: 1 in. (25 mm)
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed. If
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).
• 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.
