CombustibleWallPenetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield restop(s). The wall shield
restop maintains minimum clearances and prevents cold
air in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 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
10 in. (254 mm) greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the wall
shield restop is only required on one side and no heat
shield is necessary.
