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. The hearth cannot exceed 1¹⁄₂”
(38 mm) in height from bottom of fireplace for ease of
door accessibility. (Fig. 4)
Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory the outer walls be insulated to
conform to applicable insulation codes.

Clearance to Combustibles
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. 3a and 3b, the following Mantel Charts.
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.
