6-Year Limited Tank/ 6-Year Limited Parts Warranty*
96% THERMAL EFFICIENCY CONTINUOUS HOT WATER
VERSATILE POWER DIRECT VENT
• Today’s homes demand more hot water than ever before, and the 96% efficient power
need. The 50-gallon heater delivers hot water output that exceeds a 75-gallon
atmospheric gas water heater. In fact, the fully condensing design is so advanced, it can
deliver continuous hot water for shower after shower…a continuous flow of over
4 gallons per minute. * Yet is easy to install, with height, diameter and installation
requirements similar to standard power direct vent units.
HELICAL INTERNAL HEAT EXCHANGER
• Completely surrounded by water in tank, provides much greater heat transfer
surface than standard straight flue tube
• Helps produce 96% thermal efficiency, which saves money on operating costs compared to a standard
80% efficient gas water heater
•
over time.
POWER DIRECT VENT DESIGN
• Uses inexpensive PVC, CPVC or ABS pipe for intake and exhaust.
• Can be vented vertically thru-the-roof or horizontally thru-the-wall
– 2” pipe, vents up to 45 equivalent feet
– 3” pipe, vents up to 128 equivalent feet
• Optional concentric and sidewall termination kits available
CONDENSING DESIGN
• 96% efficient condensing design
• Equipped with condensate drain tee
SIDE-MOUNTED HOT AND COLD RECIRCULATING TAPS
• Allows water heater to be installed as part of combination space heating/water heating applications or
any system requiring a recirculating hot water loop, including radiant floor heating
ADVANCED ELECTRONIC CONTROL
• Large LCD display
• Precise temperature control
• Advanced diagnostics
COMMERCIAL GRADE GLASS LINING
• Provides superior protection against corrosion
• Protects all interior tank surfaces including inside and outside of helical heat exchanger
TWO HEAVY-DUTY ANODE RODS
• Provides added protection against corrosion
