Page 21 TABLE OF CONTENTS 6 720 606 446 US (06.01) AL This well engineered, gas water heater has all the features a water heater should have: It operates on the principle of heating water instantaneously “on demand”. When a hot water faucet is opened, cold water flows through the coils of the heat exchanger in the Aquastar. This same flow opens the gas valve, and the burners are ignited by the pilot flame. The heat exchanger coils absorb the heat generated by the burners and transfer heat to the water. When the hot water faucet is shut off, the gas valve automatically closes and the burners turn off. Your hot water faucet is an ignition key to turn on the water heater, giving you control over your hot water energy use. Each time you turn off your hot water faucet, you also shut off the water heater. FEATURES -High Quality Materials for Long Working Life. -Copper heating coils for endless supply of hot water. -Safety thermocouple at pilot burner. -Automatic overheating protection shut-off sensor. -Stainless steel burners with stabilized blue flame. -Built-in corrosion resistant draft inducer. -Compact space saver: mounts on a wall with two hooks. -Easily removable one-piece cover. -Easy one person installation. -Adjustable water flow restrictor to ensure that water flow demand will not exceed the heating capacity of the heater. -Easy pilot flame lighting with push button piezo ignition.
