maintenance
SpARk pLUg:
Clean and re-gap every 600 hours of operation, or replace as needed.
After removing the Spark Plug, clean the terminals with a wire brush. Re-
gap the terminals to 0.140” (3.5mm).
pHOTOCELL:
The Photocell should be cleaned at least once per heating season or
more depending on conditions.
Use a cotton swap dipped in water or alcohol to clean the lens of the
Photocell.
NOZZLES:
Nozzles should be cleaned or replaced at least once per heating
season. Contaminated fuel could make this necessary
immediately
.
To clean dirt from nozzle, blow compressed air through nozzle
front. It may be necessary to soak nozzle in clean 1-K kerosene
to help loosen any particles.
NOTE:
Use of diesel may require additional maintenance. Using
this heater without proper maintenance or with contaminated or
old fuel may lead to improper combustion and possible soot
production. BE SURE FUEL USED IS APPROVED (see
OPERATION on page 6).
SPARK PLUG:

needed.After removing the Spark Plug, clean the terminals with a
wire brush. Re-gap the terminals to 0.140” (3.5mm).
PHOTOCELL:
The Photocell should be cleaned at least once per heating
season or more depending on conditions.
Use a cotton swap dipped in water or alcohol to clean the lens of
the Photocell. Note the proper Photocell position as noted in

FUEL FILTER:
The Fuel Filter should be cleaned at least twice per heating
season by rinsing it in clean 1-K kerosene. Contaminated fuel
could make this necessary immediately (See
Figure 19
).
NOTE:
To remove the filter from models PT-45 / 70T-KFA, turn
filter 90° clockwise. To remove the filter from models PT-125T /
175T / 215T-KFA, turn filter 90° counter-clockwise.
Use of diesel may require additional maintenance.
Improper
maintenance can lead to poor combustion and soot
production!
PUMP PRESSURE ADJUSTMENT:
While heater is operating, turn relief valve clockwise to increase,
counterclockwise to decrease (see
Figure 20
). Use flat blade
screwdriver to turn valve. Correct pump pressure is as follows:
For best measurement of pressure, test with full tank of
fuel.
Optimum pressure occurs when the nose cone is
cherry red and there are no extending flames from the
heater.
