Direct Vent Design

One-pipe, dual-channel closed system draws all make-up air from outside the home, eliminating problems caused by insufficient indoor ventilation and is FVIR compliant. Horizontal air intake and venting on all models up to 80 inches from outside the wall with no electrical power needed .

Intelligent Control Logic

The internal microprocessor provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance.

Uses a thermopile to generate the power needed to operate the electronic gas control without requiring an external power source.

The electronic gas control incorporates an LED status indicator that monitors system operation and service diagnostics.

Green Choice® Gas Burner

Patented eco-friendly design reduces NOx emissions by up to 33% and complies with Low-NOx emission requirements of less than 40 ng/J.

DynaClean™ Diffuser Dip Tube

Helps reduce lime and sediment buildup, maximizes hot water output. Made from long lasting PEX cross-linked polymer.

Gas water heaters heat water by burning either natural gas or LP (propane). Gas water heaters need a source of air and also need to be vented properly. Cold water enters the water heater through an internal “dip tube” which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection. This arrangement provides the most hot water for a given tank size. Most gas water heaters use a pilot light. The pilot light on some models also generates the power needed to operate an electronic gas valve. When cold water enters the tank, the temperature sensor on the gas control tells the main gas valve to open. Gas flows to the burner where it is lit by the pilot light. The air needed by the burner is supplied by the room where the water heater is installed. The exhaust gases are vented to the outside. When the proper temperature is reached, the main gas valve shuts off. Because water can corrode the steel tank, we glass line the inside of the tank and install an anode rod to help reduce corrosion. The temperature and pressure relief valve is a safety device designed to open if the internal temperature or pressure of the tank exceeds certain limits. Water heaters should be large enough to provide adequate hot water even when temperatures are cold and household demand is greatest.

Rebate and incentive programs provide cash-back to consumers for the purchase of appliances that meet certain energy efficiency standards. Often, these standards are tied to the ENERGY STAR® certification program.

Cash for Appliances is designed to encourage the purchase of energy efficient appliances. Consumers who purchase ENERGY STAR® certified or CEE qualified appliances can receive cash rebates. Most states are offering rebates in the $50 to $250 range.
