Installation
Installing Heat Guards over Terminations
1. Ensure that the two long mounting brackets are facing the bot-
tom of the termination. (See inset). This will provide more heat
protection at the top of the termination, where temperatures are
highest.
Installing Terminations with MSR Frames
1. Frame the termination opening to 12" x 12".
2. Fasten the MSR frame to the exterior side of the studs using at
least 4 screws. Attach the termination to the MSR using a mini-
mum of 4 screws.

Installing Terminations with MOSR Frames
1. Frame the termination opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs using a
minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, and
attach by screwing through the four pilot holes in the termination.
Venting Runs
If your installation requires more than 12" of horizontal venting, some
vertical lift is required. Use the vent graph below to determine an
acceptable vent run. Unacceptable venting can affect the fireplace's
combustion.
 the maximum horizontal vent run is 16 feet
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 6) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Figure 6. Venting Graph.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 60", and the horizon-
tal run to the wall flange of the vent termination is 36", this would
be an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 96" and the horizontal
run to the wall flange of the vent termination is 144", this would
be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 48" and
the horizontal run to the wall flange of the vent termination is
120", this would NOT be an acceptable installation.
