Oil Burner
Troubleshooting
To diagnose malfunctions properly, the following test equipment is required:
1) An electrical test meter that can measure AC volts, ohms, and amps;
2) A combustion analyzer kit to measure oxygen and/or carbon dioxide,
smoke, stack temperature, and draft; and
3) Two pressure gauges with scales of 0-100 PSIG and 0-30 PSIG.
Before test firing, check the combustion chamber for an excessive accumu-
lation of unburned oil and restore to safe condition before firing. (See page
25.)
WARNING: Do not attempt to start the burner when
excess oil has accumulated, when the combustion
chamber is full of vapor, or when the combustion
chamber is very hot.
NOTE: Refer to the troubleshooting guide below to select the appropriate
troubleshooting chart.
