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.

AVAILABLE IN NATURAL GAS OR PROPANE

CSA CERTIFIED AND ASME RATED T&P RELIEF VALVE

STANDARDS AND CERTIFICATIONS

• Design-certiﬁed by CSA International according to ANSI Z21.10.3 – CSA 4.3 Standards.

• Meets UBC, CEC, and ICC National Codes.

• Meets the thermal efﬁciency and standby loss requirements of the U. S. Department of Energy and current edition of ASHRAE/ IES 90.1.

10-YEAR LIMITED TANK AND 1-YEAR PARTS WARRANTY

• For complete information, consult written warranty or go to hotwater.com.

*When sized appropriately. Model GTP 199 can deliver 6.95 GPM continuous ﬂow, based on 65°F inlet water temperature, 120°F outlet temperature.
