FEATURES

84% THERMAL EFFICIENCY – The absolute highest thermal efficiency possible by a non-condensing boiler is achieved by the new Genesis Boiler.

Low NOx –Precise amounts of gas and air are premixed through special Pre-Jet Orifices and forced through stainless steel burners that provide complete and clean combustion. Meets or exceeds California SCAQMD air quality standards.

EXCLUSIVE DIA-SCAN II W/STAGED FIRING – The Dia -Scan II is a complete microprocessor based boiler control. Every electrical boiler function; from starting the pump, to stage firing the main burner, to cycling the pump off at the end of a heating cycle; is controlled and monitored by the onboard computer. A comprehensive display panel includes LEDs that indicate current operating and fault status. A digital LED displays temperature set points, outlet temperature, current inlet/outlet differential (∆T), tank temperature, and additional numerical fault codes. Precise temperature management is plus or minus 1°. In addition, the Dia-Scan II provides true self-diagnostic capabilities, eliminates guesswork, and reveals exactly where the problem is. Troubleshooting has never been easier.

STAGED FIRING – All second family Genesis boilers are staged fired. The boiler automatically adjusts its firing rate and btu output to maintain precise system temperature control. Each stage is user programmable; allows the boiler to be tailored to the installation and adjusted for optimum boiler performance and overall system efficiency. Models GW-1000 thru GW-1500 have three stages; Models GW-1850 thru GW-2500 have four stages.

HEATEXCHANGER

HEAVY-DUTY CAST HEADERS – Choose from heavy non-ferrous all bronze headers or heavy cast iron Cora-Shield Coated headers. Genesis boiler headers are split bolted designs that allow complete and easy inspection of all internal header water surfaces and easy inspection of the copper tubes.

HIGH EFFICIENCY HIGH HEAT TRANSFER – A.O. Smith’s distinctive double row integral finned copper heat exchanger provides maximum heat transfer and utilizes a self-baffling staggered tube design, that assures 84% thermal efficiency.

INTEGRAL REAR HEADER BOILER MOUNTED PUMP – Factory sized and integrally rear header mounted, pre-wired bronze fitted pump is standard. Dia-Scan II controlled pump time delay allows the removal of useable residual heat from the combustion chamber during the stand-by cycle. Practically eliminates stand- by heat loss.

FACTORY TESTED – Each Genesis boiler is water and fire tested before leaving the factory

UNMATCHED VENTING FLEXIBILITY – Multiple venting options; choose from several conventional or direct venting options. Multiple openings options; choose from exhaust outlet leaving the top of boiler or exhaust outlet-leaving the rear of boiler.

STACKABLE SPACE SAVING DESIGN – Up to 5 million btu's in

the space of a 2.5 million btu boiler.
