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 3,8 cm.
• SLP heat shield - designed to be used on a wall 11,1 cm to 19,4 cm thick.
• If wall thickness is less than 11,1 cm the existing heat shields must be field tricmed.
If wall thickness is greater than 19,4 cm 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 inch (3,8 cm)
overlap of attached heat shields must be maintained.
• See Section 10.G 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 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.
