Wall Penetration Framing/Firestops - Heat & Glo TIARII-BR-IPI Installation Manual

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.
