DEFENDER SAFETY SYSTEM® HIGH EF DAMPER ATMOSPHERIC VENT MODELS

These models feature an automatic flue damper that helps to reduce stand-by heat loss. The flue damper, combined with additional insulation and heat traps, helps these units achieve one of the highest Energy Factor (EF) ratings of our atmospheric vent models. These models qualify for the current ENERGY STAR® EF requirement and for the September 1st, 2010 EF requirement, as well as most utility company rebate programs.
