Burner Manual
Troubleshooting
Oil burners that are designed for use in pressure washers
are built to take temperature extremes, vibration, and rough
handling. When performing the following troubleshooting
steps, we assume that the oil burner motor and ignition
transformer operate continuously and the oil solenoid
valve, which controls oil
fl
ow, is cycled by the trigger in the
wand. We also assume that there is power to the burner
and fuel in the tank.
In addition to normal mechanics tools, it is recommended
to have the following equipment on hand.
○
Meter capable of measuring volts, ohms and amps,
○
ignition transformer tester,
○
smoke pump tester,
○
combustion analyzer, and
○
0 to 200 psi pressure gauge.
