The Robertshaw® Pilot Orifices are used as replacement parts in Robertshaw pilots and pilot assemblies.

The Robertshaw® 712 Series Intermittent Pilot Ignition System Kit features flame rectification with solid-state logic and flame sensing to provide automatic sequencing that will ensure proper operation of an intermittent pilot ignition device. The 712 pilot ignition systems are available with one of four different gas valve types to fit a wide range of furnace applications. Caution: Do not use on LP gas applications.

780-790

The Robertshaw® 780 Series Hot Surface Controls are designed for use on gas fired systems. The system acts on a demand for heat by a switch or thermostat to supply power to the ignition control. On non pre-purge models, the ignitor will be energized immediately and remain on for either of two optional selected ignitor heat-up times: approximately 17 or 34 seconds. For models with the prepurge option, there is a time delay equal to the heat-up time selected before the ignitor is energized. At the end of the ignitor heat-up time, the gas valve is opened supplying gas to the main burner. After several seconds, the ignitor is turned off and the sensor is energized. As long as flame is sensed, the system continues to operate.

780-003

The Robertshaw® Universal Ignition Control Uni-Kit® is available in both nonlockout (780-001) and lockout (780-002). The 780-003 is lockout with a prepurge function. The kit a flame sense circuit that automatically detects the presence of a remote sense probe (2 rod system) or it switches to local sense (1 rod system) utilizing the pilot assembly as a sensing source. If both systems are provided, failure of one causes automatic reversion to the other.
