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 so fitted) and the fireplace. Refer to Fig. 4a and
Fig. 4b, and the Mantel Charts below for the correct
mounting height and widths.
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.
To prevent discoloration, use only heat-resistant paint
or lacquer to finish the mantel.

A hearth is not mandatory, but is recommended for
aesthetic purposes. We recommend using 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
noninsulated exterior wall or chase,
it is mandatory that the outer walls be
insulated to conform to applicable
insulation codes.
