2 State On-Demand Gas Water Heaters A comprehensive line of tankless water heaters. Designed for Residential or Commercial applications. Interior and Exterior installation options. Natural Gas or Propane. Choose from 16 different models. 1

3 The Durability of State Combines the durability of State and the convenience of continuous flow delivery. States On-Demand water heaters uses a high-fire burner to quickly raise the temperature of water passing through a copper heat exchanger. Since the burner is not ignited until there is a demand for hot water, it is highly energy efficient. 2

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

5 Convenience and Control 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. Standard Remote Controller Commercial Remote Controller 4

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

13 Sizing

14 Model Selection Guide To properly size On-Demand units for a home, two factors are of critical importance... 1.Incoming ground water temperature -Will determine the amount of temperature rise required to achieve the desired hot water outlet temperature (120ºF is recommended) 2.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
