The Lochinvar & A.O. Smith 100093847 Ignition Control Relay is an essential component of gas-fired water heaters and boilers and is used in their ignition system. It closely controls the ignition process so that the burner is ignited in the best way possible. It only starts firing the gas and the spark when the system is ready to go which enhances safety and performance unlike other systems. Often used in HVAC applications like domestic hot water tanks and industrial boilers, this relay increases energy savings besides reducing equipment down time that lead to a more effective heating solution.
