This valve must be marked with a maximum set pressure not to exceed the marke working pressure on the water heater. This valve must also have an hourly rated temperature steam BTU discharge capacity not less than the hourly input rating of the water heater. Install the valve into the opening provided and marked for this purpose in the water heater, and orient it or provide piping so that any discharge from the valve will exit only within 6 inches above, or at any distance below the structural floor and cannot contact any live electrical part. No valve is to be placed between the relief valve and tank. The discharge line must be installed to allow complete drainage of both the relief valve and the discharge line. The discharge line must not be restricted or reduced in size under any circumstances. The end of the discharge line opening should terminate near a floor drain or other suitable location not subject to blocking or freezing. DO NOT thread, plug or cap the discharge line. Leave an air gap of approximately six (6) inches between the end of the discharge line and a drain pan.After the installation of all water lines, open the main water supply valve and fill the heater. Open several hot water faucets to allow air to escape from the system while the heater if filling. When water passes through the faucets, close them and check for possible leaks in the system.ELECTRICAL CONNECTIONS:Before any electrical connections are made,be sure that the heater is full of water and that the valve in the cold water supply line is open. Check the rating plate and wiring diagram before proceeding. This electric water heater was built and wired in accordance with the Underwriters' Laboratories' testing approvals requirements. The temperature limiting device is of the manual reset,trip-free type and has been factory installe to interrupt all ungrounded power supply conductors in the event of thermostat failure. Thermostats are factory set and wired in accordance with the wiring diagram fastened to the inside of the top access panel.The dealer in your area ordered this heater wired at the factory to comply with existing area codes, but local utility codes may require or allow other circuity. Consult your local power company to determine the correct electrical hook-up in order to meet local utility and building codes and in order to obtain the most economical rates. Also check to find out if you are required to obtain a permit before starting the installation. The following chart shows the recommended fuse size for the maximum heat wattage. The maximum wattage and rated voltage are shown on the heater data plate.The heater must be well grounded. A green ground screw is provided at the electrical connection point for connecting a ground wire.OPERATION:Before closing the switch to allow electric current to flow to the heater, make certain that the heater is full of water and that the cold water inlet valve is open. Complete failure of the heating elements will result if they are not totally immersed in water at all times. When the switch is closed, the operation of this electric water heater is automatic The thermostats are preset to the "HOT" setting to provide a water temperature of approximately 120oF to reduce the risk of scald injury.CAUTION: Scalding may occur within five (5) seconds at a temperature setting of 135oF.This water heater is capable of delivering high temperature hot water at any faucet in the system. Care must be taken whenever using hot water to avoid scalding injury. Certain appliances require high temperature hot water (such as dishwashers and automatic clothes washers). In order to prevent potential scald injury, install an antiscald tempering valve in the water system. Valves for reducing point of discharge temperature by mixing cold and hot water in branch water lines are available. A qualified plumber should be consulted.The temperature of the water can be changed by adjusting the thermosta Before any work is done on the heater, disconnect all power to the heater by opening the switch at the main electrical circuit breaker of fuse box. Remove the access panels or front panel on table tops, fold the insulation outward away from the controls. Set the thermostats to the desired water temperature using a screw driver to move the thermostat pointer, replace the insulation making sure that the controls are well covered and that the plastic terminal shield has not been displaced; then replace the access panel. The heater is now ready for operation and the main switch can be closed. For Your Safety: Increasing the wattage and/or voltage from factory original equipment can require changes to the water heater and/or the electric service. Unauthorized modification of the water heater may create a hazard to life and property and will nullify the warranty. Contact your dealer or utility company before making any changes.CAUTION: INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF SCALD INJURY.When necessary to completely drain the heater, shut to off the electric power supply to heater, close cold water inlet, open a hot water faucet to allow air to enter the system and open the drain valve, which is threaded to receive a standard hose coupling. On Table Top models, the front panel must be removed to gain access to the drain valve.CAUTION: Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally two weeks or more.) Hydrogen gas is extremely flammable. 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 connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.MAINTENANCE:Shut off the electric power whenever the water supply is turned off. Shut off the electric power, water supply and drain the heater completely to prevent freezing whenever the building is left unoccupied during the cold weather months. In order to insure efficient operation and long tank life, drain the heater through the drain valve until water runs clear. Drain it at least once a month. Failure to do this may result in noisy operation and lime and sediment buildup in the bottom of the tank. Check the temperature-pressure relief valve to insure that the valve has not become incrusted with lime. Lift the lever at the top of the valve several times until valve seats properly without leaking and operates freely.SAFETY WARNING: When lifting lever of temperature/pressure relief valve, hot water will be released under pressure. Be certain that any released water does not result in bodily injury or property damage. The magnesium anode rod should be inspected periodically and replaced when necessary to prolong tank life.SERVICE:The manual reset, trip-free temperature limiting devices on this heater will cut off all power to heater if temperature of water exceeds 190oF. If there is no hot water after a reasonable period of time, check the main fuse box. In the event that the fuses have not blown, call a serviceman; have him check the entire circuit including the elements and thermostats before resetting the temperature limiting device. Heater must be disconnected from power supply before servicing switch. Consult the plumber or electric service company in your area for all service,replaceme parts or any questions you might have regarding this heater. Insist on factory inspected and approved replacement parts.A combination anode rod/hot water outlet nipple has been installed to extend tank life. This rod should be inspected periodically and replaced when necessary. Contact manufacturer listed on rating plate foreplacement anode information. The use of a water softener may increase the speed of anode consumption. More frequent inspection of the anode is needed when using softened (or phosphate treated) water.
