Benefits
ENERGY EFFICIENT DAMPER DESIGN
24 VAC Powered flue damper*
Lower stand-by losses
More hot water at a lower operating cost
Automatic spark to pilot ignition system eliminating the need for a standing pilot
AUTOMATIC GAS CONTROL
Adjustable thermostat will provide years of reliable trouble-free service at the desired water temperature and an energy cut-off (E.C.O.) is provided for abnormal conditions
Integrated self-diagnostic system control minimizes guesswork
Modular valve for ease of replacement
FLAMMABLE VAPOUR DETECTION SENSOR
Protective control system that disables the heater in the presence of flammable vapour accumulation
FVIR compliant
RESETTABLE THERMAL CUT-OFF
Shuts down gas flow to the pilot and burner in the event that flammable vapours enter into the combustion chamber and ignite. Simple and easy to service, push the button to reset.
SIGHT GLASS
Provides easy viewing into the combustion chamber to verify the operation of the pilot and burner.
STAINLESS STEEL FLAME ARRESTOR
Superior no-rust design prevents flammable vapours from igniting outside of the sealed combustion chamber.
LOW MAINTENANCE OPERATION
Air intakes and flame arrestor designed to minimize dirt and dust accumulation.
DRAIN VALVE
Excellent quality, tamper resistant, one-piece brass drain valve is installed for easy drainage.
INSULATION
A thick uniform blanket of 
eco-friendly insulation keeps the water hotter for longer periods, reduces standby losses and energy costs. contains no HCFC’S (hydrochlorofluorocarbons), CFC’S (chlorofluorocarbons), HFC’S (hydrofluorocarbons) nor VOC'S (volatile organic compounds).
PATENTED «POWER TWISTTM»
Gives a higher efficiency than regular baffles. You get more hot water from the same gas consumption!
FACTORY INSTALLED T&P RELIEF VALVE
Protects the tank from the damaging effects of excessive water temperature and pressure.
FACTORY INSTALLED 3/4" NPT DI-ELECTRIC NIPPLES
Extend the life of the water heater by providing excellent corrosion protection.
GLASS-LINED INNER TANK
A uniquely formulated blue cobalt glass enriched with zircon is fused to specially treated steel at 1,600°F (871°C) to provide the best coating available against corrosion for many years. The tank is certified at a test pressure of 300 PSI (2,068 kPa) and a working pressure of 150 PSI (1,035 kPa).
HIGH-QUALITY MAGNESIUM ANODE
Provides excellent protection against the corrosive effects of water and extends tank life.
ROLL-AROUND BASE
Provides easy handling for installer without damaging the floor during installation.
*Included : Standard 110 volt plug-in transformer with electrical power cord.
FVIR Technology
All residential gas fired water heaters built with FVIR technology, meet the latest edition of the North American Standards ANSI Z21.10.1/CSA 4.1.
