Supco IG401 Hot Surface Ignitor

The Supco IG401 Hot Surface Ignitor produces the heat required to ignite a compatible burner fuel mixture during an ignition sequence. Its hot-surface element reaches ignition temperature when energized, creating a localized heat source for burner light-off in HVAC systems. Positioned at the burner ignition point, the ignitor transfers heat directly to the fuel-air mixture, allowing ignition to proceed without a standing pilot flame, and its controlled electrical heating provides the required ignition source for each commanded start. This operation supports repeatable burner startup and proper sequencing of combustion equipment.
