$168.15
The Model HS780 Series Hot Surface Ignition Modules is designed for use on gas fired heating systems.
The system acts on a demand for heat by a switch or thermostat to supply power to the ignition control.
On this non pre-purge model the ignitor will be energized immediately and remain on for either of two optional selected ignitor heat-up times approximately 17 or 34 seconds.
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.
When the thermostat is satisfied, the gas control will be closed to shut off the main burner.
This HS780 Ignition Control provides lockout and complete gas shut off if ignition is not proven after the trial for ignition sequences has been completed.
To reset the system the thermostat or system switch must be opened for at least 10 seconds. Molded-in terminal barriers between terminals.
This HS780 includes mounting screws to help provide a positive ground connection.
Small compact size provides "no hassle" installation.
