ABSTRACT:
A sequencing and monitoring control device for fuel burners is provided having a unique burner program. The fuel burner is put into operation with an ignition means turned on, along with fuel pressure and combustion air, but without fuel being intentionally introduced into the combustion chamber. This start-up procedure would ignite any leakage fuel. The ignition is ended and an attempt is made to sense whether a flame exists thereby indicating the presence of leakage fuel. If any flame exists, the system shuts down on safety. If none exists, the sequence proceeds to a preselected burner sequence.
