PROBLEM CAUSE SOLUTION
Burner will not ignite. No spark Check/adjust electrodes.
Ensure that there is power to the
power supply.
Check and clean cad cell.
Too much air Check/adjust air flow. (Factory set
numbers: Top burner bulk air
band is set at 1 and air shutter is
set at 4. Lower burner bulk air
band is set at 1 and air shutter is
set at 3.])
There is air in the fuel supply
system.
Push RESET button on burn
control. Ensure that all fuel line
connections are tight. Air should
purge after repeating this step
two or three times.
Fuel pump coupler is damaged. Replace coupler.
Fuel pump is bad. Low pressure. Check fuel pressure (see setting
for fuel pressure on Page 23).
Set fuel pressure.
Replace pump.
Possible air lock on fuel line. If fuel lines are tight and there is
plenty of fuel; and if the fuel filter
is good and still no fuel, unscrew
filter cap. Fill up halfway with fuel.
Carefully screw cap back and
restart cycle. You may have to do
this two or three times to help
purge and prime pump if system
is airlocked.
Dark smoke is emitted from the
unit.
Adjust airflow to upper burner. The airflow can be adjusted by
rotating the air inflow bracket on the side of the motor. The air flow
adjustments are factory-set but may need to change, depending on
the type of material you are burning. [Factory set numbers: Top
burner bulk air band is set at 1 and air shutter is set at 4. Lower
burner bulk air band is set at 1 and air shutter is set at 3.]To
eliminate smoke, increase the amount of air supplied to the top
burner and decrease the amount of air to the lower burner until the
optimum setting is reached. As the bracket is rotated, larger
numbers on the scale indicate more air intake; lower numbers on the
scale indicate less air intake. For normal operation, the operator will
learn which setting for air intake best suits the typical load.
