Copeland Comfort Control (White Rodgers) PG9A37JTL22S2 Pilot Generator 750mV

The Copeland Comfort Control (White Rodgers) PG9A37JTL22S2 Pilot Generator is required for gas-fired HVAC systems such as furnaces and water heaters. It produces a small 750 mV DC voltage when heated by the pilot flame. This voltage illuminates the gas valve safety circuit allowing the flow of gas only when the pilot is on to avoid gas leakage. Its use also does away with the need for external power sources for the pilot safety circuit to ensure ignition and safe operation of these HVAC systems. Advantages include safety improvement, assured pilot ignition, and energy conservation due to the discontinuation of the constant use of pilots in some systems.
