WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:
• Between ceiling restops
• Between wall shield restops
• Around vent system
Failure to keep insulation or other material away from
vent pipe may cause overheating and re.

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 restop(s). The wall shield
restop maintains minimum clearances and prevents cold
air in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 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 restop is required on one side
only on interior walls. If your local inspector requires a
wall shield restop on both sides, then both wall shield
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 restop is only required on one side and no heat
shield is necessary.
