Vent Clearances and Framing
Figure 5.2 Wall Penetration
Figure 5.1 Horizontal Venting Clearances To Combustible
Materials
* 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).

B. Wall Penetration Framing/Firestops
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 in
fi
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.
• DVP pipe - A wall shield
fi
restop is required on one side
only on interior walls. If your local inspector requires a
wall shield
fi
restop on both sides, then both wall shield
fi
restops must have a heat shield (refer to Section
12.A.) attached to them.
• See Section 7.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 non-com-
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
fi
restop is only required on one side and no heat
shield is necessary.
* Shows center of vent framing hole for top or rear venting. The center of the
hole is one (1) in. (25.4 mm) above the center of the horizontal vent pipe.
