* When using SLP pipe, minimum clearances from the vent pipe to combustible materi-

als 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).

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).

A. Pipe Clearances to Combustibles

WARNING! Risk of Fire! Maintain air space clearance to

vent.

DO NOT pack insulation or other combustibles:

• Between ceiling fi restops

• Between wall shield fi restops

• Around vent system
Failure to keep insulation or other material away from

vent pipe may cause over heating and fi re.

B. Wall Penetration Framing

Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must

frame a hole for the wall shield fi restop(s). The wall shield

fi restop maintains minimum clearances and prevents cold

air infi ltration.
• 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 fi restop 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.K. 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 fi restop is only required on one side and no heat

shield is necessary.
