) or oxygen (O
2
) analyzer,
•
A flue gas temperature measuring device (e.g., thermocouple or thermister probe with readout
device),
•
An analog or digital multimeter, and
•
An oil pressure gauge capable of reading 0-150 PSIG.
To initially fire the oil burner, proceed in the following manner:
a. Turn the disconnecting switch, which provides power to the appliance, to the "OFF" position.
