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 insulated
to conform to applicable insulation codes.
Hearth
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the appliance.

1/2” drywall while flange “B” is for 5/8” drywall.

the fireplace. Slide the fireplace into the framed

of the framing. Level the unit and secure it firmly in
