OIL BURNER
1.BURNER FAILS TO START:
A.Defective on/off or fuel transfer switch. Replace switch.
B.Control circuit has an open control contact. Check limits, low water cutoff, proof of closure switch and others as applicable.
C.Bad fuse or switch open on incoming power source. Correct as required.
D.Motor overloads tripped. Reset and correct cause for trip out.
E.Flame safeguard control safety switch tripped out. Reset and determine cause of apparent flame failure.
F.Loose connections or faulty wiring. Tighten all terminal screws and consult wiring diagram furnished with the burner.
G.Frozen oil pump shaft preventing blower motor operation. Replace oil pump.
H.Flame safeguard control starting circuit blocked due to flame relay being energized. Possible defective scanner or photocell - replace. Possible defective amplifier - replace. Scanner actually sighting flame due to leaking fuel valve - correct unwanted flame cause. Defective flame safeguard control - replace.
I.Defective blower motor. Repair or replace.
2.OCCASIONAL LOCKOUTS FOR NO APPARENT REASON:
A.Check for proper settings on direct spark oil ignition electrodes. Make certain that gap is not too wide and the
B.Direct spark ignition. Verify that there are no cracks in the porcelain and that transformer end and electrode end
C.Loose or broken wires. Check all wire nut connections and tighten all terminal screw connections in panel and elsewhere as appropriate.
D.Occasional low supply voltage. Contact local utility to correct. Make certain the burner control circuit transformer (if supplied) is correct for the voltage and power (VAC) being supplied.

G.Ignition transformer defective. Replace.
H.Ignition electrode set incorrectly. Remove electrodes and reset.
I.Ignition electrodes cracked and grounding out spark. Replace electrodes.
J.Ignition leadwire defective and grounding out spark. Replace.
K.Ignition plug in connections at transformer or electrode loose. Tighten.
L.Air flow switch not making circuit. Adjust set point or replace.
