HIGH EFFICIENCY
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.
• 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.
