									Section: Troubleshooting
□ Clean the cad cell, if applicable.						Table 2. Nozzle Flow Rate by Size
□ Make	sure	Low Firing	Rate Baffle is	in place, if		Nozzle flow rate U. S. gallons per hour of No. 2 fuel oil
required, for the burner application. Omitting the baffle						when pump pressure (psig) is:
can result in unacceptable burner combustion.
□ Inspect all gasket including the igniter				base	plate	Nozzle
gasket. Replace any that are damaged or missing.						Size	125	140	150	175	200
□ Clean the blower wheel, air inlet, air guide, retention						(rated

□ Check motor current.			The amp draw should not

exceed the nameplate rating. Check all wiring for
loose connections or damaged insulation.						0.50	0.56	0.59	0.61	0.66	0.71
□ Check the pump pressure and cutoff function.						0.60	0.67	0.71	0.74	0.79	0.85
□ Check primary control safety lockout timing, if						0.65	0.73	0.77	0.80	0.86	0.92
applicable. Refer to the information supplied by the
						0.75	0.84	0.89	0.92	0.99	1.06
control manufacturer for procedures.
□ Check ignition system for proper operation.						0.85	0.95	1.01	1.04	1.13	1.20
						0.90	1.01	1.07	1.10	1.19	1.27
□ Inspect the exhaust system for soot accumulation or
other restriction.						1.00	1.12	1.18	1.23	1.32	1.41
□ Clean the equipment thoroughly according to the						1.10	1.23	1.30	1.35	1.46	1.56
manufacturer’s recommendations.

Oil burners that are designed for use on road maintenance
equipment	are	built to take temperature extremes,

vibration, and rough handling. When performing the following troubleshooting steps, we assume that the oil burner motor and ignition transformer operate continuously and the oil solenoid valve, which controls oil flow, is cycled by the equipment controls. We also assume that there is power to the burner and fuel in the tank.

In addition to typical mechanics tools, it is recommended to have the following equipment on hand.

○Meter capable of measuring volts, ohms and amps,

○ignition transformer tester,

○smoke pump tester,

○combustion analyzer, and

○0 to 200 psi pressure gauge.

See Table 4 on following page for troubleshooting steps.
