MAINTENANCE
For efficient and safe operation and to extend the
life of heater, it should be cleaned and inspected for
damage annually, preferably at the beginning of the
heater season, or more often in dirty environments.
Other than cleaning, the heater requires no other
preventative maintenance.
WARNING! To prevent a possible electric shock,
always unplug heater from outlet before
cleaning or servicing. Allow heater to cool
before cleaning to prevent a possible burn.
1. Heater cabinet may be cleaned using a damp
cloth to remove dust that may have accumulated
on surfaces. Do not use harsh cleaners and waxes
on surfaces, as these could damage or discolor the
finish.
2. A vacuum cleaner or compressed air may be used
to remove dust and lint accumulated inside heater
around element fins.
CAUTION! Fins are sharp and may cause cuts.
Avoid contact.
3. After cleaning and servicing, reassemble by
replacing any hardware removed and check unit to
make sure it operates properly.

OPERATION CONTINUED
4. Allow heater to operate normally until the room
reaches desired temperature.
NOTE: This heater is designed to slowly radiate
gentle, even heat. It may take several hours to
reach the desired temperature.
5. Rotate thermostat knob counterclockwise until a
click is heard. Thermostat will automatically cycle
heater on and off as needed to maintain desired
room temperature.
NOTE: A new smell coming from the heater
may be detected during initial use. Operate
heater on highest setting for at least one hour
to minimize the new smell. Heater may not
heat up immediately because of the tubular
element design. Heater will take a few minutes
before warmth will be felt.
