Emerson conditions-White Rodgers 789A-801A1 Nitride Hot Surface Ignitor 120V Lennox Replacement

The Emerson conditions-White Rodgers 789A-801A1 Nitride Hot Surface Ignitor is an essential part that is used in HVAC systems, especially for Lennox models. This ignitor works at 120V and uses a nitride material to heat up quickly to ignite the natural gas without the presence of a continuously burning pilot light. When the thermostat calls for heat, an electrical current passes through the ignitor, and the metal becomes red hot, over 1,000°F, and ignites the gas entering the burner assembly. The advantages of using this hot surface ignitor include enhanced furnace performance, less gas costs due to the use of less fuel, and higher dependability than conventional ignition systems.
