POLARIS

COMMERCIAL HIGH EFFICIENCY GAS WATER HEATERS

POLARIS

34 Gallon 50 Gallon

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 transfer more heat into the water.

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

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 minimize noise.

Power Direct Vent Design

• Direct vent using PVC, CPVC or ABS either thru-the-wall or thru-the-roof.

• Optional concentric vent kit

Advanced Electronic Control

• Large LCD display provides precise temperature control and advanced diagnostics.

Code Compliance

• Complies with SCAQMD Rule 1146.2 and other air quality management districts with similar requirements for Ultra-Low NOx emissions requirements of 14 ng/J or 20 PPM.

• 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.

THE RIGHT CHOICE FOR COMMERCIAL HOT WATER

POLARIS® COMMERCIAL WATER HEATERS AT A GLANCE

For more than 140 years, we at A. O. Smith have taken pride in being the innovative

leader in water heating. We’ve worked to instill our long experience of innovation into

a comprehensive line of residential and commercial water heaters for any application.

Polaris

High Efficiency Water Heaters embody all that’s best about the A. O. Smith

brand. Our world-class engineering team has combined high BTU inputs, storage

capacity, and small physical footprint to create a product unlike any on the market.

Polaris

is all about packing the biggest punch into a small footprint. With a range of

inputs (up to 199,000 BTU/hr), the Polaris can deliver continuous hot water for multiple

tasks like dish washing and restrooms. Pair that with 34 or 50 gallons of available

storage for those times when you need a “burst” of hot water. It is constructed from

stainless steel for years of trouble-free service.
