A. Pipe Clearances to Combustibles
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.

Vent Clearances and Framing
Figure 8.1 Horizontal Venting Clearances To Combustible
Materials
* When using SLP pipe, minimum clearances from the vent pipe to combustible materi-
als at wall shield firestops are: Top: 2-1/2 in. (64 mm)
Bottom: 1/2 in. (13 mm)
Sides: 1 in. (25 mm)
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184
mm) thick.
,f wall thickness is less than 4 in. the e[isting heat shields must be field trimmed. ,f
wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.
SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to
194 mm thick).
,f wall thickness is less than 4-3/8 the e[isting heat shields must be field trimmed.
,f wall thickness is greater than 7-5/8 in. a DVP-HSM-B will be required.

B. Continue Adding Vent Components
WARNING! Risk of Fire! Installation of this appliance
may require the use of heat shield 385-920 above the
rst 90
0
elbow in the venting system.
The heat shield is required above the rst elbow if the
clearance to combustible surface above is between
three (3) and four (4) inches. A shield is not required for
clearances greater than four inches. See Figure 8.2.
Fasten the shield in place using the four pilot holes
provided in the part. The shield should be oriented such
that the 13-1/8 inch dimension (longest dimension) is
running in the same direction the elbow is pointing. The
shield should be centered directly above the elbow, and
positioned so that it creates a 1/2 inch airspace between
the shield and the combustible surface. See Figure 8.3.
