Safety Precautions AWARNING J Improper installation, adjustment, alteration, service or maintenancecan cause DEATH, SERIOUS BODILY INJURY,J OR PROPERTY DAMAGE. Refer to this manual for assis- tance or consult your localSearsService Center for further information. AWARNING At the time of manufacture thiswater heater was provided with a combination temperature-pressures 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 Valvesand Automatic Gas Shutoff Devicesfor Hot Water Supply Systems, andthe current edition of ANSI Z21.22, CSA 4.4 and the code requirements of ASME. If replaced, the valve must meet the requirements of local codes, but not lessthan a combination temperature and pressure relief valve certified as meeting the requirements for Relief Valvesand Automatic Gas Shutoff Devicesfor Hot Water Supply Systems, ANSI Z21.22, CSA 4.4 by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials. The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 Ibs./sq. in.) and a discharge capacity not lessthan the water heater input rate as shownon the model rating plate. (Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr. rate.) Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI Z21.22, CSA 4.4 and ASME, may require a valve model different from the one furnishedwith the water heater. Compliance with such local requirements must be satisfied by the installer or end user of the water heater with a locally prescribed temperature-pressure relief valve installed in the desig- nated opening in the water heater in place of the factory furnished valve. For safe operation of the water heater, the relief valve must not be removed from it'sdesignatedopening or plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Positionthe valve downward and provide tubing so that any dischargewill exit only within 6 inchesabove, or at any dis_ tance below the structural floor. Be certain that no contact is made with any live electrical part. The dischargeopening must not be blocked or reduced in size under any circumstances. Excessivelength, over 30 feet, or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unlessa 6" air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage. The Discharge Pipe: • Must not be smaller in size than the outlet pipe size of the valve,or haveany reducing couplingsor other restrictions. • Must not be pluggedor blocked. • Must be of material listed for hot water distribution. • Must be installed soas to allow complete drainage of both the temperature-pressure relief valve,and the dischargepipe. • Must terminate at an adequate drain. • Must not haveany valve between the relief valve and tank. 2 AWARNING HAZARD OF ELECTRICAL SHOCK! Before removing any access panels or servicing the water heater, make I sure the electrical supply to the water heater is turned "OFF". Failure to do this could result in DEATH, SERIOUS BOD LY NJURY, OR PROPERTY DAMAGE. AWARNING HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, shall be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves. Before changing the factory setting on the thermostat, read the "Temperature Regulation" section in this manual. AWARNING WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This water heater is equipped for one type voltage only. Check the rating plate near the bottom access panel for the correct voltage. DO NOT use this water heater with any voltage other than the one shown on the model rating plate. Failure to use the correct voltage can cause problems which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your electric company. AWARNING INSULATING JACKETS: When installing an external water heater insulation jacket on an electric water heater: a. DO NOT cover the temperature-pressure relief valve. b. DO NOT put insulation over the access covers or any access areas. c. DO NOT remove operating instructions, and safety related warning labels and materials affixed to the water heater. d. DO obtain new warning and instruction labels from Sears for placement on the jacket directly over the existing labels. AWARNING Do not use this appliance if any part of it hasbeen under I water. An electrical short or malfunction could occur. The water heater sboud be rap aced. A CAUTION WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available at your local hardware store. Such a drain pan must be piped to an adequate drain.
