route cord under furniture or appliances. Arrange
cord away from traffic areas and where it will not be
tripped over.

• Always unplug heater when not in use.

• To disconnect, rotate thermostat to the LO set point

OPERATION

IMPORTANT! This heater is a major electrical
appliance and requires adequate electrical

power. The outlet in use must be a 120 volt
circuit protected by a 15 or 20 amp fuse or
circuit breaker. No other major electrical
appliance should be operated in the same
circuit as the heater.

Use care when choosing the location and
using the heater. Do not block the heater in
any way to prevent air to flow freely through
the heater. Keeping the heater clean will also

improve the efficiency and prevent
overheating. See Maintenance on page 3 for
cleaning information.

WARNING! The heater plug must fit tightly into
outlet. A loose fitting or worn outlet may cause

plug connection to heat, damage plug or
outlet and cause a fire. If outlet is loose or worn,
discontinue using heater until the outlet can be

replaced.

CAUTION! High Temperature. Keep electrical
cords, drapes and furnishings away from

heater. Do not allow curtains or other furnishing
to contact heater. Maintain at least 6"
clearance around the heater at all times.

To reduce the risk of fire, do not store or use
gasoline or other flammable substances near

heater.
