NTI 84738-1 Igniter Flame Sensor Combo

This NTI Igniter Flame Sensor Combo is a dual-function device designed for use in heating systems. The igniter component, made from silicon nitride, initiates the combustion process by producing a spark to light the fuel. The flame sensor, on the other hand, is responsible for monitoring and verifying the presence of a flame in the system. If no flame is detected, the sensor sends a signal to shut down the fuel supply as a safety measure. This combo unit is compatible with various NTI boiler models and is designed for easy installation and reliable performance. It operates under standard voltage requirements and has a robust construction to ensure durability and longevity.
