Removal of Soot from Heating Coil:
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipe, and
block air flow which will affect burner combustion. When
soot has been detected on visual observation, the soot
on the coil must be washed off after following the coil
removal steps (See Coil Removal on page 9).
Rupture Disk:
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst allowing
high pressure to be discharged through hose to ground.
When disk ruptures it will need to be replaced. Torque to
35 ft. pounds.
Fuel:
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain tank every 100
hours of operation.
Use No.1 or No 2 Heating Oil (ASTM D306) only. NEVER
use gasoline in your burner fuel tank. Gasoline is more
combustible than fuel oil and could result in a serious
explosion. NEVER use crankcase or waste oil in your
burner. Fuel unit malfunction could result from contami-
nation.
Fuel Control System:
This machine utilizes a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combus-
tion chamber. The solenoid, which is normally closed, is
activated by a flow switch when water flows through it.
When the operator releases the trigger on the spray gun,
the flow of water through the flow switch stops, turning
off the electrical current to the fuel solenoid.
The solenoid then closes, shutting off the supply of fuel
to the combustion chamber. Controlling the flow of fuel
in this way gives an instantaneous burn-or-no-burn situ-
ation, thereby eliminating high and low water tempera-
tures and the combustion smoke normally associated
with machines incorporating a spray gun. Periodic in-
spection, to insure that the fuel solenoid valve functions
properly, is recommended. This can be done by operat-
ing the machine and checking to see that the burner is
not firing when the spray gun is in the OFF position.
Fuel Pressure Adjustment:
To control water temperature, adjust fuel pressure by turn-
ing the regulating pressure adjusting screw clockwise to
increase, counterclockwise to decrease. Do not exceed
200 psi. NOTE: When changing fuel pump, a bypass
plug must be installed in return port or fuel pump will not
prime.

Burner Nozzle:
Keep the tip free of surface deposits by wiping it with a
clean, solvent saturated cloth, being careful not to plug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
