MAINTENANCE
Service:
DO NOT TAMPER WITH THE UNIT. HAVE A
COMPETENT SERVICEMAN MAKE ANY NECESSARY
ADJUSTMENT OR REPAIRS.
Use only original equipment 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 tank every 200 hours of operation or as needed.
DO NOT flush with water; use fresh K-1 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.
The output and lint filters should be replaced
every 500 hours of operation or less depending on
conditions. (See Figure 3)
NOTE: Use of diesel fuel may require additional main-
tenance
FAN BLADES:
Blades should be cleaned at least once per heating
season, depending on conditions. Remove all
accumulated dust and dirt with a damp cloth, taking
care not to bend any of the fan blades. Be sure the
blades are dry before re-starting the heater.
FUEL FILTER:
The fuel filter should be cleaned at least twice
per heating season. Clean the filter by rinsing it in
clean K-1 Kerosene. Contaminated fuel could make
cleaning the fuel filter necessary immediately.
NOTE: To remove the filter from models 45 - 80T-KFA
turn filter 90º clockwise. To remove the filter from
models 140T - 215T-KFA turn filter 90º counter-clock-
wise. See Figure 2.
THERMISTER PLACEMENT:
Ensure the thermister wire is in the proper place. The
wire should be lying on the bottom shell inside the
heater with the plastic end placed under the motor
support/motor and away from fan blade.
ROTOR:
The rotor with carbon vanes should be evaluated every
heating season. The rotor is behind the air filters. The
vanes should be inspected for damage or wear. The
rotor should be inspected for damage, chips, wear,
cracks.
Check rotor gap:
Remove the rear cover. Loosen
the two pump ring screws. Lift the pump ring
upwards. Insert a 0.1 mm feeler gauge and apply
slight downward pressure, enough to offer resis-
tance when attempting to remove gauge.
Hand-tighten the two pump ring screws. Re-install
the End Pump Cover and the plastic End Filter Cover.
Start the heater and adjust to the proper pump
pressure.
