Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting height and widths, refer to
Figures 4a, 4b and the Mantel Chart below.
The distances and reference points are not affected by
the fitting of a bay window front trim kit.
Noncombustible mantels and legs may be installed at
any height and width around the appliance. When using
paint or lacquer, it must be heat resistant to prevent
discoloration.

A hearth is not mandatory, but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a non-in-
sulated exterior wall or chase, it is manda-
tory that the outer walls be insulated to
conform to applicable insulation codes.

Framing and Finishing
Check fireplace to make sure it is levelled
and properly positioned.
To mount the appliance: Choose the location. (Fig. 5)
1. 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.
2. 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.
