HeatStream HS-215T-KFA - Manual (Page 11)

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 HS-45 / 70T-KFA, turn
filter 90° clockwise. To remove the filter from models HS-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.
