Maintenance
Never service heater while it is plugged in

Use only original equipment replacement parts. The use of
alternate or third party components can cause unsafe operating
conditions, and will void your warranty.
We suggest following a maintenance schedule as follows:
FUEL/FUEL TANK:
Flush every 200 hours of operation or as needed. Do not use
water to flush the tank. Use fresh 1-K kerosene only.
AIR FILTERS:
The Air Intake Filter should be replaced or washed with soap and
water and dried thoroughly every 500 hours of operation, or less,
depending on conditions.
