INSTALLING A WALL MOUNT, DIRECT VENT TERMINATION

This section applies to installations where the direct vent termination will
be wall mounted.

(A) Installation of Termination with built in frame

A Termination with a Built-In Frame is installed during framing of a structure.
1. Frame the termination opening to 12" x 12".
2. Install exterior sheathing to the structure framing.
3. Fasten the termination to the sheathing using a minimum of 4 screws.

(B) Installation of termination frame only at time of framing

Terminations with a MSR frame allow the installation of the frame prior to installation
of the termination.
1. Frame the termination opening to 12" x 12".
2. Secure the MSR Frame to the exterior sheathing of the structure.
3. Fasten the termination to the MSR Frame using a minimum of 4 screws.

(C) Installation of termination frame in Masonry

Terminations with a BSR frame allow the installation of the frame in masonry prior
to the installation of the termination
1. Frame the BSR opening to 12" x 12".
2. Secure the BSR Frame to the exterior sheathing of the structure.
3. Fasten the termination to the BSR Frame using a minimum of 4 screws.

1. Frame the MOSR opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs, concrete, or finished
wall construction using a minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, (from the inside)
and attach to the MOSR by installing a min. quantity of 4 bolts into the threaded
nuts on the MOSR Frame.

(E). Installation of a termination shield for Vinyl Siding

The VSS Termination shield is installed when the exterior of a structure is clad with
Vinyl siding. It is placed directly above, and on-center with the termination.
Figure 14. Installing the VSS Vinyl Shield.
Installing Heat Guards over Terminations is recommended in installations where the
termination is located within 7' feet above grade, or above a pedestrian walkway,
and may be Required by code in Public areas.
Figure 13c. Installing a PTO termination heat guard.
1. Ensure that the two long mounting brackets are facing the bottom of the
termination. (See inset). This will provide more heat protection at the top of
the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal screws.
