Instead of using a continuously burning pilot light found in most traditional gas furnaces, this Trane RunTru gas furnace uses a silicon nitride hot surface ignition system that lights the main burners on demand, reducing fuel usage. This more modern ignition system is safer than a pilot light and eliminates the chore of checking and relighting the pilot.

For additional safety, this Trane RunTru gas furnace uses a dual solenoid combination gas valve and regulator.
