Vent Clearances and Framing
Fire Risk.
Explosion Risk.
Maintain vent clearance to combustibles as
specifi ed.
• Do not pack air space with insulation or other
materials.
Failure to keep insulation or other materials
away from vent pipe may cause fi re.
WARNING
Figure 6.1 Horizontal Venting Clearances To Combustible
Materials
* When using SLP pipe, minimum clearances from the vent pipe to combustible materi-
als at wall shield 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).
• DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184
mm) thick.
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed. If
wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.
• SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to
194 mm thick).
• If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed.
If wall thickness is greater than 7-5/8 in. a DVP-HSM-B will be required.

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.
• 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 16.B.)
attached to them.
• See Section 10.M. 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
one in. 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.
