Vent Clearances and Framing

B. Wall Penetration Framing

Refer to Figure 8.2.

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.

• 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 attached to them.

• See Section 10.I. for information for regarding the

installation of a horizontal termination cap.

als

Noncombustible Wall Penetration

If the hole being penetrated is surrounded by noncombus-
tible materials such as concrete, a hole with diameter one
inch greater than the pipe is acceptable.

Whenever a noncombustible wall is penetrated, the wall
shield fi restop is only required on one side and no heat
shield is necessary.
