Heat & Glo LifeStyle 6000GCF-IPILP Wall Penetration Framing, Combustible Wall Penetration

B. Wall Penetration Framing

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

The heat shield is 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. (102

mm)the existing heat shields must be field trimmed. If wall thickness is greater than 7-1/4 in. (184 mm) a DVP-HSM-B will be required.

Combustible Wall Penetration

Frame a hole in a combustible wall for an interior wall shield firestop, (Figure 6.3) whenever a wall is penetrated. Use same size framing materials as those used in the wall construction. The wall shield firestop maintains minimum clearances and prevents cold air infiltration.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by noncombus- tible 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 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.
