11. MAINTENANCE
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.
WARNING: ENSURE HEATER HAS FULLY
COOLED AND DISCONNECT FROM POWER
SUPPLY BEFORE CONDUCTING ANY
MAINTENANCE.
11.1 FUEL/FUEL TANK
− Flush every 200 hours of operation or as
needed. Do not use water to flush the tank.
Use fresh Diesel or Kerosene ONLY.
11.2 AIR FILTERS – FIG.5
− The Air Intake Filter (3) should be replaced
or washed with soap and water and dried
thoroughly every 500 hours of operation,
or less, depending on conditions.

damp cloth, taking care not to bend any of the

− Be sure fan blades are dry before re-starting
the heater.
11.4 NOZZLES – FIGS.7–8
