Supco IG406 Furnace Ignitor

The Supco IG406 Furnace Ignitor is a silicon carbide hot surface ignition component to initiate gas combustion in furnaces, boilers, and other heating equipment. It heats up when electrical current passes through it and reaches ignition temperature to light the gas burner during start-up. It connects to the control circuit through insulated leads that support steady electrical flow to the ignition element. Within HVAC systems, it is positioned in the burner assembly section to enable controlled ignition of heating cycles in residential and commercial heating applications where gas-fired operation is used.
