Clean or replace. Rinse after each use.
Open chemical valve or clean.
Submerge strainer and replenish chemical.
Inspect hose, replace as necessary.
Repair or replace check valve.
Open by turning counter clockwise.
Open dual wand or install low pressure tip.
Inspect hose, replace as required.
Check screen on strainer pickup tube.
Disassemble, clean or replace.
Use with cold water (150º Maximum) If installed
on discharge side of coil.
Turn machine off, wait a few minutes and
restart. If problem continues, take in for repair.
Take in for system check.
Turn switch on; Thermostat on if equipped.
Fill burner tank with #2 diesel.
Squeeze trigger to fire burner.
Clean or tighten fuel filter. (Check fuel pressure)
Clean spray nozzle.
Reset overload, locate source of overload.
Install nozzle in wand.
See pumping systems trouble shooting.
Check fuel pressure, filter, fuel lines. Replace
fuel pump and/or nozzle.
Check electrical continuity with pump spraying
and burner on.
Replace fuel valve if it does not open when
power is applied.
Adjust generator RPM for proper voltage under
full load conditions.
Replace burner relay.
Set air band and fuel pressure to specs.
Replace nozzle of proper size.
Replace ignition transformer, clean and adjust
electrodes.
Set air band and fuel pressure to specs.
Clean soot off to improve air flow.
Adjust RPM of generator (if equipped)
Decrease fuel pump pressure and/or fuel nozzle size.
Clean or replace nozzle of proper size. Descale
coil and clear obstructions.
Replace or reset temperature limit switch.
Replace switch.
Replace solenoid.
Increase fuel pump pressure and/or fuel nozzle
size.
Have battery checked and load test, replace if
necessary.
Engine RPM should be 3400-3600 RPM w/no load.
Check engine charging system - Must have 16
Amp output.
Adjust electrodes to maximum 1/8" gap.
Adjust for proper burn.
Check amp draw of burner motor - should be 13
amp or less. Check amp draw of transformer
should be 4.2 or less.
PROBLEM
Inlet injection will not siphon chemical.
Water is emitted from the chemical
pickup tube.
Downstream injector will not siphon
chemical.
Pressure relief relieving water.
Burst disk relieving water.
Burner will not fire.
Burner will not fire, plus diesel fumes
are emitted from the exhaust port.
Burner fires and smokes.
Discharge water temperature exceeds
recommended operating temperature.
Burner continues to fire even when
trigger on spray gun is released
Discharge water temperature not
reaching maximum operating temperature.
Battery keeps losing voltage.
(For 12 volt burner systems)
Heating/Burner System-Diesel Fired
WARNING: High voltage on ignitor
can cause electrical shock.
Disconnect power before servicing.
WARNING: Replace insulation.
Unburned fuel can saturate it and
cause a fire.
