Mantels
The height at which 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. For correct
mounting height and width, refer to Fig. 4a and 4b and
the Mantel Chart below.
The fitting of a bay window trim kit does not affect the
distances and reference points referred to in the dia-
gram and chart.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using paint or lacquer to finish the mantel, such
paint or lacquer must be heat resistant to prevent dis-
coloration.

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