The burner will operate in the following sequence: Prepurge for the first 10 seconds; fire until the thermostat is satisfied or the limit setting on the high limit is reached; post-purge for the last 10 seconds. When the pressure limit control restores the circuit on a drop in pressure, the burner will start if the thermo stat is still calling for heat. The probe low water cut-off will shut down the burner after a 10-15 second delay, if the water level in the boiler drops below the probe level.
