20005004
Hearth Requirements
The Freestanding Stove and Hearthmount Shell must
be installed on rigid flooring. If the appliance is in-
stalled on any combustible surface other than wood
flooring, such as carpet or tile, a metal or wood panel
must be installed to extend the full length and width of
the unit.
• Do not install this heater in a bathroom or
bedroom.
• Installation of this heater must conform with
local codes or, in the absence of local codes, with
the National Fuel Gas Code, ANSI Z223.1 / NFPA54.
• This heater creates warm air currents. These
currents move heat to wall surfaces next to the
heater. Installing the heater next to vinyl or cloth
wall coverings or operating the heater where
impurities in the air such as tobacco smoke exist,
may discolor walls.
• Do not use a blower insert, heat exchanger
insert or other accessory not approved for use
with this heater.
