Anleitung Zusammenfassung
The 50-gallon water heater delivers hot water output that rivals a 75-gallon atmospheric gas water heater. In fact, the fully condensing design is so advanced, it can deliver “endless hot water for showers”…a continuous flow of over 3 gallons per minute. * Yet it is easy to install, with height, diameter and installation requirements similar to standard power-vent units. HELICAL INTERNAL HEAT EXCHANGER • Positioned in the center of the tank, surrounded by water to virtually eliminate radiant heat loss from the chamber • Achieves 90% thermal efficiency which saves money on operating costs compared to a standard 78% efficient gas water heater • Spiral heat exchanger reduces the accumulation of lime scale; maintains higher efficiency performance over time. POWER VENTS USING PVC PIPE • Combined vertical and horizontal vent runs terminating through an outside wall, using Schedule 40 PVC pipe • Can be vented vertically thru-the-roof or horizontally thru-the-wall – 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 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 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 • Provides superior protection against corrosion • Protects all interior tank surfaces including inside and outside of helical heat exchanger VG6250T76NV TWO HEAVY-DUTY ANODE RODS • Provides added protection against corrosion GREEN CHOICE® GAS BURNER • Patented “Eco-Friendly” design reduces NOx emissions by up to 33% and meets less than 40ng/j requirements for low NOx CSA CERTIFIED AND ASME RATED T&P RELIEF VALVE MAXIMUM HYDROSTATIC WORKING PRESSURE: 150 PSI *3.07 GPM continuous flow, based on 65°F inlet water temperature, 110°F outlet temperature. **Intelli-Vent is a registered trademark of Emerson Electric Company *For complete warranty information consult the written warranty of American Water Heaters found at or call (800) 456-9805.
