Timer circuit 125 permanently shuts down system on repeated failure to reach flame temperature
A timer circuit and thermostat 125 allows safety probe 120 a given period of time to reach temperature; if probe 120 fails to attain temperature within that time on repeated restart attempts, the entire circuitry is shut down permanently, denoting major system failure rather than simple flame-out.
