CALIBER DIRECT VENT INSTALLATION INSTRUCTIONS
Secure the shield to the framing as shown in
Figure 33.
Interior Wall Shield
The last section of vent may require cutting,
depending upon wall thickness and appliance
location. The cap should overlap the vent sections
by at least 1-1/2 in. See Figure 34.
Note:
If cutting is necessary, you must use
f i r e - p a r t s . c o m
DVP12MI and DVP24MI pipe.

e. Installing the Rear Vent Heat Shield
For rear vented appliances, a heat shield MUST
be placed 1 in. above the top of the vent between
the wall shield and the termination cap. There
are two sections of the heat shield. One section
attaches to the wall shield with two screws. The
remaining section is attached to the cap in the
same manner. The sections of the heat shield
will overlap to match the wall thickness (depth).
If the wall thickness does not allow the required
1-1/2 in. heat shield overlap (for rear vented
appliances), a DVP-HSM Extended Heat Shield
must be used. You must cut the DVP-HSM to the
thickness of the wall and attach to the wall shield.
The small leg on the heat shield should rest on
the top of the vent to properly space it from the
pipe section. See Figure 35. This heat shield is
not necessary on top vented appliances.

Rear Vent Heat Shield
WARNING - RISK OF FIRE!
Always maintain minimum air space
clearances or greater around the appliance
and vent system.
f. Termination
Vent termination must not be recessed in the wall.
Siding may be brought to the edge of the cap
base.
Install the cap as shown in Figure 34. Cap pipe
sections should overlap the vent pipe by 1-1/2 in.
Caulk outside edges of cap.
Local codes may require the installation of a cap
shield (DRC-RADIUS or COOL-ADD) which
prevents anything or anyone from touching the
hot cap.
Figures 36-39 illustrate cap locations and
clearances as prescribed by current ANSI Z223.1
and CAN/CGA-B149 Installation Codes.
