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
Figs. 4a and 4b, and the following Mantel Charts.
The fitting of a bay window trim kit does not effect
the distances and reference points referred to in the
diagram 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 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
CFM146
non-insulated exterior wall or chase,
it is mandatory that the outer walls
be insulated to conform to applicable
insulation codes.
Proposition 65 Warning: Fuels used in gas, wood-
burning or oil fired appliances, and the products of
combustion of such fuels, contain chemicals known to
the State of California to cause cancer, birth defects
and other reproductive harm.
