Residential Gas Water Heaters

FEATURES

INTELLIGENT CONTROL LOGIC

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

SELF-POWERED ELECTRONIC GAS VALVE

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

DIAGNOSTICS

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

DYNACLEAN™ DIFFUSER DIP TUBE

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

“ENVIRONMENTALLY-FRIENDLY” 2 INCH NON-CFC FOAM INSULATION IMPROVES EFFICIENCY

COREGARD™ ANODE ROD

Flammable Vapour Ignition Resistant (FVIR) Water Heaters

A. O. Smith FVIR design meets or exceeds the American National Standards Institute standards (ANSI Z21.10.1 - CSA 4.1) that deal with the accidental or unintended ignition of flammable vapors, such as those emitted by gasoline.

Feature a sealed combustion chamber with air intake filter and a flame arrestor built into the water heater base. In addition, a thermal cutoff (TCO) device, is designed

to shut off gas flow to the burner and pilot if poor combustion is detected.
