INSTALLING A WALL MOUNTED DIRECT VENT
TERMINATION
This section applies to installations where the direct vent termi-
nation 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.
