INSTRUCTIONS
Your heater is designed for years of trouble-free operation and
requires no special maintenance other than occasional cleaning.
The motor is permanently lubricated.
Cleaning
Once each year, the heater should be cleaned to remove dust
and other foreign material which has collected during the heating
season, as follows:
1. Turn power off at main switch.
2. Remove bottom bezel and the two screws that hold the grille.
3. Use vacuum cleaner with brush attachment to remove dust
and dirt that has accumulated in heater (especially around
element and blower blade). Do not use water or any cleaners
to clean heater components.
4. Replace grille and bottom bezel.

any cleaners that leave a residue since these may discolor
during heater operation.

power to heater. The heater is now ready for another season
of operation.
