RESIDENTIAL GAS WATER HEATERS

POLARIS™ HIGH EFFICIENCY

COMMERCIAL-GRADE RESIDENTIAL

The Polaris high efficiency gas water heater is the high performance answer for today’s hot water needs. It can provide endless hot water* and can be used for a combination of domestic hot water and space heating.

CONDENSING DESIGN

•Operates at up to 96% thermal efficiency which saves money on operating costs compared to a standard 80% efficient gas water heater.

•Helical internal heat exchanger keeps hot combustion gases in the tank longer to extract more heat into the water.

STAINLESS STEEL CONSTRUCTION

•Tank and helical heat exchanger are constructed from 444 stainless steel for excellent corrosion resistance without the need for an anode.

WHISPER QUIET OPERATION

•Ultra quiet blower and burner to minimize noise.

POWER DIRECT VENT DESIGN

•Direct vent using PVC, CPVC or Polypropylene (solid core only) through a sidewall or roof.

•Optional concentric vent kit.

•2” pipe vents up to 52 equivalent feet (100-150k BTU/hr inputs)

•3” pipe vents up to 130 equivalent feet

ADVANCED ELECTRONIC CONTROL

•Large touchscreen display

•Precise temperature control

•Advanced water heater status and diagnostics

FULLY SERVICEABLE FROM

THE FRONT

•Two front access panels expose all serviceable components. Modular components are all easily removed.

ULTRA-LOW NOX MODULATING GAS BURNER

•Enhanced Ultra-low NOx burner complies with SCAQMD Rule 1146.2 and other Air Quality Management Districts with similar requirements for NOx emissions of less than 14 ng/j.

•Modulating burner maintains high efficiency operation at lower input rates.

SIDE-MOUNTED HOT AND COLD RECIRCULATING TAPS

•Polaris can be easily installed with a recirculation system or as part of a combined domestic & space heating system.
