Flue Pipe Clearances To Combustibles; Wall Penetration Framing - Heat & Glo SL-350TRS-CE-D Installer's Manual

B. Flue Pipe Clearances to Combustibles
wARNING
Fire Risk.
Explosion Risk.
Maintain flue pipe clearance to combustibles
as specified.
• Do not pack air space with insulation or other
materials.
Failure to keep insulation or other materials
away from flue pipe may cause fire.
Note: Heat shields MUST overlap by a minimum of 4 cm.
• DVP heat shield - designed to be used on a wall 10.2 cm to 18.4 cm) thick.
• If wall thickness is less than 10 cm, the existing heat shields must be field trimmed.
If wall thickness is greater than 18.4 cm, a DVP-HSM-B will be required.
• 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
trimmed. If wall thickness is greater than 19.4 cm, a DVP-HSM-B will be required.

Combustible wall Penetration
Frame a hole in a combustible wall for interior and exterior
wall shield firestops, (Figure 29) whenever a wall is pen-
etrated. Use same size framing materials as those used
in the wall construction. The wall shield firestops maintain
minimum clearances and prevent cold air infiltration.
Note: When penetrating a combustible wall, both interior and
exterior wall shield firestops are required.
Non-Combustible wall Penetration
If the hole being penetrated is surrounded by noncombus-
tible materials such as concrete, a hole with diameter 2.5
cm greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the wall
shield firestop is only required on one side and no heat
shield is necessary.
If your local inspector requires the wall shield firestop on
both sides, then both wall shield firestops must have a heat
shield attached to them.
