NOTICE: This appliance is intended for
supplemental heating. Use this heater
along with your primary heating system.
Do not install this heater as your primary
heat source. If you have a central heating
system, you may run system’s circulating
blower while using heater. This will help
circulate the heat throughout the house. In
the event of a power outage, you can use
this heater as your primary heat source.
CAUTION: This appliance creates warm
air currents. These currents move heat to
wall surfaces next to appliance. Installing
appliance next to vinyl or cloth wall cover-
ings or operating appliance where impurities
(such as tobacco smoke, aromatic candles,
cleaning
fluids
, oil or kerosene lamps, etc.)
in the air exist, may discolor walls.
IMPORTANT:
Vent-free heaters add moisture to the air.
Although this is
beneficial,
installing
appliance
in rooms
without enough ventilation air may
cause
mildew to form
from too much moisture. See Air for Combustion and
Ventilation, page 4.
CHECK GAS TYPE
Use the
correct
gas type (natural or propane/LP) for your
appliance.
If your gas supply is not
correct
or if you do not
