NOVUS DIRECT VENT INSTALLATION INSTRUCTIONS
H. VENTING - FRAMING & CONSTRUCTION
1. Install the Interior Wall Shield
Frame a hole in a combustible wall for an interior wall
shield, as shown in Figure 34 (rear vent) and Figure 35
(top vent) whenever a wall is penetrated. This shield
maintains minimum clearances and prevents cold
air infiltration.
The termination cap location must meet all local and
national codes and not be easily blocked or
obstructed. See Termination Cap Location.
If the hole being penetrated is of noncombustible
materials, a 9 in. diameter hole is acceptable.
Secure the shield to the framing as shown in Figure 36.
The last section of vent may require cutting, depending
upon the wall thickness and appliance location. The
cap should overlap the vent sections by at least 1½ in.
See Figure 37.

and DVP24MI pipe.
