Residential Gas Water Heaters
90% THERMAL EFFICIENCY ENDLESS HOT WATER VERSATILE POWER-VENT DESIGN
Today’s homes demand more hot water than ever before, and the 90% efficient Vertex power-vent gas water heater offers unprecedented levels of performance to meet the need. The 50-gallon Vertex delivers hot water output that rivals a 75-gallon atmospheric gas water heater. In fact, the fully condensing Vertex design is so advanced, it can deliver “endless hot water for showers”…a continuous flow of over 3 gallons per minute.* Yet Vertex is easy to install, with height, diameter and installation requirements similar to standard power-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 90% thermal efficiency, which saves money on operating costs compared to a standard 78% efficient gas water heater
POWER VENTS USING PVC PIPE
•Combined vertical and horizontal vent runs terminating through an outside wall, using Schedule 40 PVC pipe
•2" pipe, vents up to 25 equivalent feet
•3" pipe, vents up to 65 equivalent feet
•4" pipe, vents up to 128 equivalent feet
MODULAR BLOWER
•Equipped with 120 volt, 60 Hz electrical system (rating 5 amps or less), 6-foot cord with standard 3-prong connector
•2" PVC pipe, elbows and condensate drain supplied to connect heat exchanger outlet to blower
•PVC Vent Attenuation Assembly (VAA) supplied
SIDE-MOUNTED HOT AND COLD RECIRCULATING TAPS
•Allows Vertex 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
INTELLI-VENT™ GAS CONTROL
•Equipped with nearly indestructible silicon nitride hot surface ignitor — no standing pilot
•Advanced electronics for more precise control of water temperature and easy to understand system diagnostics
COMMERCIAL GRADE GLASS LINING
•A. O. Smith PermaGlas® Ultra Coat™ process provides superior protection against corrosion
•Protects all interior tank surfaces including inside and outside of helical heat exchanger
TWO HEAVY-DUTY ANODE RODS
• Provide even more protection against corrosion
GREEN CHOICE® GAS BURNER
•Patented “eco-friendly” design reduces NOx emissions by up to 33% and complies with Southern California and Texas requirements
FACTORY-INSTALLED TEMPERATURE AND PRESSURE RELIEF VALVE
MAXIMUM HYDROSTATIC WORKING PRESSURE: 150 PSI
* 3.07 GPM continuous flow, based on 65ºF inlet water temperature, 110º outlet temperature.
