TROUBLESHOOTING - 6
Note:
One of the most common causes of flame failure is dirt/sediment in the oil filter, oil lines, solenoid valves
or nozzle, caused by a new delivery of oil. If the oil tank level is allowed to fall near to the bottom of the tank it is
highly probable that sediment on the bottom of the tank will be disturbed and mixed in with the new oil delivery,
especially if the delivery rate is too fas

Problem
Cause
Remedy
1. Ignition Failure
1. Oil Tank Empty
Refill the oil tank. A slight delay in the re-priming of the
fuel pump may cause the burner programmer to require
resetting before the boiler operates satisfactorily.
2. Power Supply
Check fuse or Circuit breaker. Reset or replace as
required.
3. Ignition Electrodes
Check electrodes for carbon build-up, clean if required.
Check settings adjust if required. Check for cracks in
porcelain, if found, replace.
4. Transformer
Check voltage between transformer leads at terminal block
to be sure transformer is live.
5. UV Detector
Check for ignition interference.
6. Loose wire connection
Check connections to all components.
7. Burner Control
Check voltage between pilot terminal and neutral and
ignition terminal and neutral. Check must be made before
control locks out on safety. If no power, replace control.
8. Oil nozzle clogging
Check oil nozzle(s), clean or replace as necessary.
9. Faulty Oil Pump
Check to see if oil is being pumped to the boiler nozzle.
Repair or replace as necessary.
2. Flame Failure
(see note)
1. Power Supply
Check fuse or Circuit breaker. Reset or replace as
required.
2. Ignition Electrodes
Check electrodes for carbon build-up, clean if required.
Check settings adjust if required. Check for cracks in
porcelain, if found, replace.
3. Main Air Adjustment
Check air adjustment. Air may be blowing flame away from
the UV detector. Open primary air until fire brushes the
furnace wall.
4. UV Scanner
Check for dirt on scanner, clean as required. Check for
proper location of detector.
5. Contact open on
Adjust to proper setting air safety switch.
6. Scanner wiring reversed at
panel
Change to correct terminals.
7. Oil Supply
Check oil level in supply tank, ensure it is not below intake
line. Fill tank with oil. Check for clogged nozzle. Clean or
replace. Check oil filter and replace if necessary.
8. Oil Valve
Check the voltage between oil valve neutral at terminal
block to be sure oil valve is getting power.
9. Oil Pump
Check for clogged strainer or filter. Remove and
clean. Check for slipping or broken coupling. Tighten or
replace. Check for seized pump shaft. Replace.
10. Loss of Oil Prime
Check all lines for possible air leak in intake line and
tighten. Check the intake line is not restricted. Replace.
