Mantels
The height 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.
Refer to Figures 4a and 4b and the Mantel Charts
below them for correct mounting heights 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.
• When using paint or lacquer to finish the mantel, it
must be heat-resistant to prevent discoloration.

Although a hearth is not mandatory, one is recom-
mended for aesthetic purposes. A noncombustible
hearth which projects out 12” (305mm) or more from
the front of the fireplace is recommended.
Cold Climate Installation Recommendation:
When installing this unit against a
noninsulated exterior wall or chase,
it is mandatory that the outer walls be

insulation codes.
