Vent Clearances and Framing

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.
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).

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.
• 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
16.B.) attached to them.
• See Section 10 for information for regarding the instal-
lation 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 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.
Note: A 6 in. (152 mm) section of straight fl ue must
be attached to the fi replace before a 90° elbow.
