Ultra-low NOx Burner - Complies with Southern California SCAQMD 2008 Rule 1121 and Northern California BAAQMD 2009 10ng/J NOx emissions requirements.
Vaporshield Technology - Shuts off gas and air supply to heater to prevent prolonged vapor burn in combustion chamber should accidental or unattended ignition of flammable vapors occur outside the water heater.
Piezo Igniter - Affords push button pilot lighting in lieu of matches.
Maintenance Free - No periodic cleaning of combustion air inlet necessary under normal conditions.
Standard Thermocouple - Design provides for use of either factory supplied thermocouple or standard replacement thermocouple.
Self-cleaning - Turbulence inducing cold water inlet-tube engineered to diminish hard water area sediment deposits.
Non-CFC Foam Insulated - Saves energy and reduces fuel costs by maximizing heat retention.
High Efficiency Models - meet energy-efficiency 0.62 EF (Energy Factor) requirements of many gas utility rebate programs and comply with CEC Title 24.
Heavy Gauge Steel Tank - For extra years of trouble-free service.
Glass-lined Tank - Inner tank glass-lined with Dura-Glas™ and fired at 1600 ºF for optimum protection from the effects of corrosion.
