Framing And Finishing
Check fireplace to make sure it is lev-
elled and properly positioned.
To mount the appliance:
1. Choose the location.
2. This unit comes with four (4) flanges pre-mounted on
both sides of the fireplace to allow two different
drywall thicknesses to be used. Flange “A” is for 1/2”
drywall while flange “B” is for 5/8” drywall.
3. Bend the desired flanges out 90
°
on both sides of
the fireplace. Slide the fireplace into the framed
opening until the flanges contact the front surfaces
of the framing. Level the unit and secure it firmly in
place.
Final Finishing
Noncombustible materials such as brick or tile can be
extended over the edges of the face of the fireplace. Do
not cover the window frame assembly, any vent,
louvre assembly top or louvre assembly bottom. If a
Trim Kit is to be installed, brick and tile will have to be
installed flush with the side of this appliance.

tion and testing of any gas connection.
The gas line connection can be made with properly
tinned 3/8" copper tubing, 1/2" rigid pipe or an approved
flex connector. Since some municipalities have
additional local codes, it is always best to consult your
local authority and the CSA-B149.1 installation codes.
