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.

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