WARNING: Before installing
in a solid fuel burning fireplace,
the chimney flue and firebox
must be cleaned of soot, creo-
sote, ashes and loose paint by
a qualified chimney cleaner.
Creosote will ignite if highly
heated. A dirty chimney flue may
create and distribute soot within
the house. Inspect chimney and
firebox flue for damage. If dam-
aged, repair flue and firebox
before operating heater.
WARNING: Never install the
heater
• in a bedroom or bathroom
unless installed as a vented
appliance, see page 12

from top of heater; for side clear-
ances see Figure 4, page 10

operating heater where impurities
(such as, but not limited to, to-
bacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls or cause odors.
IMPORTANT:
Vent-free heaters add moisture
to the air. Although this is beneficial, installing
heater in rooms without enough ventilation
air may cause mildew to form from too much
moisture. See
Air for Combustion and Ventila-
tion
, page 6.
