Problem Cause Remedy
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.
Flame Failure
1. Power Supply Check fuse or Circuit breaker.
(see note ) 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 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.
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 fast.
