Electronic gas valve employs thermopile to provide electricity for operations and diagnostic display; no external power supply is needed.
Electronic gas control monitors operational conditions and helps with pinpointing service/troubleshooting matters.
Gives visual indication when pilot is lit and water heater is operating normally. Also reports status of diagnostics.
Allows for easy startup of the pilot.
Conveniently located on the side of the tank to facilitate piping to a drain or external to the building.
Reduces the risk of accidental fires involving flammable vapors from products such as gasoline, paint thinner, and solvents.
Reduces sediment buildup for heating efficiency and long tank life. (12- and 9-Year Models)
Protects tank against corrosion, maximizes tank life.
Meets or exceeds the Federal Efficiency Standards effective January 20, 2004, according to the National Appliance Energy Conservation Act (NAECA) of 1992, and current edition of ASHRAE/IESNA 90.1.
