This Type 668 Oil Burner Control provides safe operation of oil burners on heating plants where ignition during the entire burner cycle is desired. It is capable of powering external cooling loads up to 40 VA. A
* Formerly called constant ignition.
PRECAUTIONS
If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor, electrician, or someone familiar with basic electricity and wiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and ordinances.
This control is a precision instrument, and should be handled carefully. Rough handling or distorting compo- nents could cause the control to malfunction.
