Vent Clearances and Framing

A. Pipe Clearances to Combustibles
WARNING
Fire Risk.
Explosion Risk.
Maintain vent clearance to combustibles as
specifi ed.
• Do not pack air space with insulation or other
materials.
Failure to keep insulation or other materials
away from vent pipe may cause fi re.
NOTE: Slope
not required.

AROUND VERTICAL
SECTIONS
Note: When using SL pipe, minimum clearances from the vent pipe to
combustible materials at wall fi restops are:
Top: 2-1/2 inches
Bottom: 1/2 inch
Sides: 1 inch
Figure 6.1 Pipe Clearances
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 fi eld trimmed. If wall thickness is greater than 7-1/4
in. (184 mm) a DVP-HSM-B will be required.

The center of the hole is one (1) inch (25.4 mm) above the
center of the horizontal vent pipe.

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