Emerson conditions-White Rodgers 768A-842 Silicon Nitride Hot Surface Ignitor Amana

The Emerson conditions-White Rodgers 768A-842 Hot Surface Ignitor is suitable for a wide range of gas-fired HVAC systems such as boilers, furnaces, and water heaters. Using silicon nitride, this ignitor has a voltage of 80V which has a high thermal conductivity to light up the gas. The ignitor works in a way similar to a light bulb filament when electric current flows through it; the element heats up to temperatures above 1000°F, causing it to glow and ignite the gas-air mixture supplied by the appliance’s gas valve. The major advantages of an ignitor are that it is highly resistant to damage, and can handle high-temperature shock, allowing it to be used for multiple heating cycles without breaking down.
