ABSTRACT:
A control circuit for a stoker-fed heating system is effective, whenever the primary sensing control (thermostat or aquastat) of the system calls for heat, to determine whether there is sufficient fire in the furnace to assure maintained combustion, and if this is not the case, to shut the system down until combustion is again assured.
