c. To replace fuel can:
(1) Raise siphon assembly from fuel can and rest pump cylinder end in drain trough of the siphon tube
(2) Lift off empty can and hang filled can on hook.
(3) Repeat priming and lighting procedures (para 2-5)
2-7. Operation of Equipment
b. Heat output is controlled manually by adjustment of the fuel control knob, which may be varied from a low pilot
flame to maximum output.:
c. The heater operates with a yellow flame. The: starting flame may be bluish, tinged with yellow. The low fire will
be yellow and the medium and
high fire flames will become a golden yellow color. If the flame is smoky with a high flame, turn the control knob back
slightly until the flame is clean an d clear.
d. When oil gets low it is possible for an air bubble in the fuel line to stop the flow of oil. In this event, place a pan
under the fuel control valve and loosen valve strainer screws. Flow of oil will carry the bubble out.
e. The first time the heater is lighted, a slight vapor and odor will rise from the heater shell. This is due to the
protective coat of oil applied to steel parts to prevent tarnishing or rusting during shipment. It will burn off quickly and will
not be noticed again.
Section II. OPERATION UNDER UNUSUAL CONDITIONS
2-8. Operation in Extreme Cold (Below 0F)
. Service the fuel strainer (para 4-14) more frequently
to remove accumulated moisture.
b. Keep fuel can full at all times.
2-9. Operation in Dusty or Sandy Areas
a. Take all necessary precautions to keep dust and sand from: entering fuel system. Service fuel strainer more
frequently to remove accumulated sediment.
b. Provide maximum protection for the equipment at all times. Take advantage of natural barriers whenever
2-10. Operation Under Rainy or Humid Conditions
a. Close door whenever possible to keep out moisture. During dry periods, when equipment is not in use, open
door to allow the unit to dry.
b. Take all necessary precautions to keep moisture from entering the fuel supply. Service the fuel strainer more
frequently to remove accumulated moisture.
c. Dampness increases corrosive action. Wipe all accessible expose areas frequently. Paint all chipped or
scratched surfaces to prevent rust. Use petroleum jelly to protect metal surfaces. Coat all unprotected surfaces that do
not come in contact with burner or combustion chamber. If the heater is outside and not operating, protect it with a
canvas or other waterproof cover. Remove cover during dry periods.
2-11. Operation in Salt Water Areas
a. Salt water will cause corrosion of all metal parts of the space heater. Extreme care must be taken to prevent rust
from forming. Wash salt deposits from the equipment with fresh water whenever possible.
2-12. Operation at High Altitudes
a. Heat output will be reduced at 4000 feet or more above sea level.
b. Raising the position of the draft regulator will improve burner output. Add one half to one length of stove pipe
below the regulator.
