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, followed immediately by the exhaust system. Your hot water faucet is an ignition key to turn on the water heater, giving you control over your hot water energy use. Every time you turn off your hot water faucet, the energy consumption for hot water returns to zero. FEATURES -Electronic Pilot Ignition -On/Off switch to activate system -Power Venting with safety shutoff -High Quality Materials for Long Working Life. -Copper heating coils for endless supply of hot water. -Burner output proportional to hot water flow demand for maximum energy efficiency. -Safety flame sensor at pilot burner. -Automatic overheating protection shut-off sensor. -Stainless steel burners with stabilized blue flame. -Built-in corrosion resistant power venter. -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.

You should follow these instructions when you install your heater. In the United States: The installation must conform with local codes or, in the absence of local codes, the National Fuel Gas Code ANSI Z223.1/NFPA 54. In Canada: The Installation should conform with CGA B149.(1,2) INSTALLATION CODES and /or local installation codes. 2. Carefully plan where you install the heater. Correct combustion air supply and flue pipe installation are very important. If not installed correctly, fatal accidents can be caused by lack of air, carbon monoxide poisoning or fire. 3. The place where you install the heater must have enough ventilation. The National Fire Codes do not allow gas fired water heater installation in bathrooms, bedrooms or any occupied rooms normally kept closed. See the section below on locating the heater. 4. You must install your heater so that the venting complies with all requirements. Venting must comply with all requirements for Category III gas appliances. See section on Venting the Heater, pages 6 and 7. 5. The appliance must be disconnected from the gas supply piping system during any pressure testing at pressures in excess of 1/2 Psig (3.5 kPa). The appliance must be isolated from the gas supply piping during any pressure testing of the gas supply piping system at test pressures in excess of 1/2 Psig (3.5Kpa). The appliance and its gas connection must be leak tested before placing the appliance in operation. 6. Keep water heater are...
