Heat & Glo • XLR-N-CE, XLR-PB-CE • 2198-900 Rev. J • 5/1230
Note: Heat shields MUST overlap by a minimum of 38 cm.
• SLP heat shield - designed to be used on a wall 11,1 cm to 19,4 cm thick.
• If wall thickness is less than 11,1 cm the existing heat shields must be field tricmed.
If wall thickness is greater than 19,4 cm a DVP-HSM-B will be required.

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 over heating and re.

CombustibleWallPenetration
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 inltration.
• 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 3,8 cm overlap of at-
tached heat shields must be maintained.
• See Section 10.K. for information for regarding the in-
stallation of a horizontal termination cap.
Non-CombustibleWallPenetration
If the hole being penetrated is surrounded by noncom-
bustible materials such as concrete, a hole with diameter
2,54 cm 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.
