Section 3-3: Installing a Wall Mounted Direct
Vent Termination
This section applies to installations where the direct vent termination
will be wall mounted.
1). 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 11" x 11".
2. Install exterior sheathing to the structure framing.
3. Fasten the termination to the sheathing using a minimum of 4 screws.

5). 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.
2). Installation of termination frame 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.

3). Installation of termination frame at time of framing 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.
4). Installation of termination from inside structure
A Termination with a MOSR Frame is installed from the inside of the
structure. These are commonly used in high-rise construction.

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.
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.
