Our high efficiency flue damper models meet the .67 Energy Factor (EF) tier II efficiency ratings initiated in September of 2010. These natural gas water heaters feature an automatic flue damper, an electronic gas control and have an electronic ignition. These combined features ensure these models qualify for ENERGY STAR® making them eligible for most utility rebate programs based on EF Ratings.
Electronic Gas Valve
Our new high-tech gas control is a self-powered gas valve that uses a thermopile to generate the power needed to operate the control. No external power source is required. With fewer moving parts and in¬ternal components, the valve optimizes performance through improved temperature control and accuracy.
Brass Drain Valve
The durable, tamper-resistant brass drain valve contributes to improved safety and reliability.
DynaClean™ Diffuser Dip Tube
Thanks to the improved technology, the inlet tube features water jets that redirect incoming cold water into the tank, creating turbulence, which helps reduce lime build-up, therefore maintaining heater efficiency.
