Maintenance (Continued)
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 sea-
son 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
Figure 17
and
Figure 18
.
FUEL FILTER:
The Fuel Filter should be cleaned at least twice per heating sea-
son 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 HH-45 / 70T-KFA, turn
filter 90° clockwise. To remove the filter from models HH-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.
