    GENERAL INFORMATION This electric w ater heater’ s design is certified by Underw riters Laboratories (UL) and listed in accordance w ith UL 1453. C-UL listed in accordance w ith Canadian National Standard C22.2, No. 110-M90. This w ater heater must be installed in accordance w ith local codes. In the absence of local codes, install this w ater heater in accordance w ith the latest edition of the National Electrical Code.

  • Page 4: Installation

    General Information continued- A sacrificial anode(s) is used to extend tank life. Removal of any anode, except for inspection and/or replacement, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and impurities in the water.
  • Page 5 Locating The Water Heater continued- Water heater corrosion and component failure can be caused by the heating and breakdow n of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, sw imming pool chemicals, calcium or sodium chloride, w axes and process chemicals.

    Water Connections Note: Before proceeding with the installation, close the main water supply valve. After shutting the main w ater supply valve, open a faucet to relieve the w ater line pressure in order to prevent w ater from leaking out of the pipes w hile making the w ater connections to the w ater heater.
  • Page 7 Water Connections continued- WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the Requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI...
  • Page 8 Water Connections continued- WARNING Hydrogen gas can be produced in the hot water system served by this water heater when there has been no usage for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. Therefore, to reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance...
