6 Vent Clearances and Framing A* B<br />
A. Pipe Clearances to Combustibles<br />
B. Wall Penetration Framing<br />
WARNING<br />
Fire Risk.<br />
Explosion Risk.<br />
Maintain vent clearance to combustibles as<br />
specifi ed.<br />
• Do not pack air space with insulation or<br />
other materials.<br />
Failure to keep insulation or other materials<br />
away from vent pipe may cause fi re.<br />

Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).<br />
The heat shield is designed to be used on a wall 4 in. to 7-1/4 in. (102<br />
mm to 184 mm) thick. If wall thickness is less than 4 in. (102 mm) the<br />
existing heat shields must be fi eld trimmed. If wall thickness is greater than<br />
7-1/4 in. (184 mm) a DVP-HSM-B will be required.<br />

Combustible Wall Penetration<br />
Frame a hole in a combustible wall for an interior wall<br />
shield firestop, (Figure 6.2) whenever a wall is penetrated.<br />
Use same size framing materials as those used in the wall<br />
construction. The wall shield fi restop maintains minimum<br />
clearances and prevents cold air infi ltration.<br />

Non-Combustible Wall Penetration<br />
If the hole being penetrated is surrounded by noncombustible<br />
materials such as concrete, a hole with diameter one<br />
inch greater than the pipe is acceptable.<br />
Whenever a non-combustible wall is penetrated, the wall<br />
shield fi restop is only required on one side and no heat<br />
shield is necessary.<br />
If your local inspector requires the wall shield fi restop on<br />
both sides, then both wall shield firestops must have a heat<br />
shield attached to them.<br />
