  1. RELIABILITY ON DEMAND INTRODUCING A COMPLETE LINE OF TANKLESS GAS WATER HEATERS

  2. American On-Demand Gas Water Heaters • A full product line of tankless water heaters by American. • Utilized for Residential or Commercial applications. • Interior and Exterior installation options. • Natural Gas or Propane. • 16 different models covering a range of needs. 1

  3. Rely on American • Benefit from the always reliable customer service of American and the comfort of endless hot water. • Combine the efficiency of the tankless technology with the expertise of the American brand. • Gain greater flexibility when it comes to controlling water temperature in the home. 2

  4. On board diagnostics and safety monitoring Energy efficient, up to 84% thermal efficiency Continuous hot water up to 9.8 GPM (maximum flow rate) Direct electronic ignition; no pilot light Durable enough for 12-year limited warranty on heat exchanger and 5-year warranty on all parts Up to 237,000 maximum gas consumption Btu/h Natural gas or propane Reliable Technology 3

  5. Inspired Comfort Standard Remote Controller Commercial Remote Controller • All models come with a Standard Remote Controller that can set the temperature within a specific range and can provide error codes to diagnose problems. • The Commercial Remote Controller can be used to achieve temperatures above 140ºF, up to 160ºF for the 305 models and up to 185ºF for the 505 and 705 models. 4

  6. Remote Controller In Use Indicator Light Indicates hot water is being supplied (a tap is open) Temperature Display Shows the temp setting Priority Indicator Indicates that this controller is setting the temperature Error Codes When a fault is detected an error code flashes at the temperature setting Priority Button Priority can be changed to another controller if desired Thermostat Increases/decreases temp setting On/Off Button Will turn the water heater on/off 5

  13. Sizing

  14. Model Selection Guide • To properly size On-Demand units for a home, two factors are of critical importance . . . • Incoming ground water temperature - Will determine the amount of “temperature rise” required to achieve the desired hot water outlet temperature (120ºF is recommended) • Peak hot water demand - How much hot water the home will need during its busiest usage period 13

  15. Ground Water Temperature Factor 14

  16. Peak Hot Water Demand • Consider all the applications and fixtures in the home that use hot water, including lavatory faucets, kitchen faucets, washing machines, dishwashers, showers and bathtubs. • Determine how many of these appliances and fixtures will be in use at the same time during the busiest usage period. • For example, if one kitchen faucet, one shower and a washing machine are all in use during the busiest period, use the number 3 to make your selection from the Model Selection Guide. 15
