5 tYpical installation miXinG valve usaGe fiGure 2. water (potable) heating: All models are considered suitable for water (potable) heating only. H O T T E R WAT E R C A N S C A L D : 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 disabled. 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, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available from your local plumbing contractor. Consult a Qualified Installer or Service Agency. Follow mixing valve manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual. fiGure 1.
6 facts to consider aBout the location Carefully choose an indoor location for the new water heater, because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance. Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed: 1. Select a location as close as practical or centralized to the point of use. The water heater should be located in an area not subject to freezing temperatures. 2 . Selected location must provide adequate clearances for removing the front cover in order to service parts such as the thermostat, element, temperature sensor, anode, and high limit reset. Adequate clearance for servicing this appliance should be considered before installation, such as operating the relief valve, etc. 3. The water heater should be located so it is not subject to physical damage by moving vehicles or area flooding. 4. The selected wall or cabinet must be capable of supporting at least two times the weight of the water heater when filled with water (77 lbs). 5. The water heater must be installed in a vertical position with water inlet and outlet connections facing upwards and easily accessible. Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available from your local plumbing contractor. Such a drain pan must have a minimum length and width of at least 2 inches (51 mm) greater than the water heater dimensions and must be piped to an adequate drain. Water heater life depends upon water quality, water pressure, water usage, water temperature, and the environment in which t h e w a t e r h e a t e r i s i n s t a l l e d . Wa ter heaters are sometimes installed in locations where leakage may result in property damage, even with the use of a drain pan piped to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunc - tion with a piped drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways: • Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected. • Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan. • W ater supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater. insulation BlanKets Insulation blankets are available to the general public for external use on electric water heaters but are not necessary with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Should you choose to apply an insulation blanket to this heater, you should follow these instructions below. Failure to follow these instructions can result in fire, serious personal injury, or death. • Do not cover the temperature and pressure relief (T & P) valve with an insulation blanket. • Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference. • Do obtain new warning and instruction labels for placement on the blanket directly over the existing labels. locatinG the new water heater .

The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater ’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. th e temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected. It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expansion tank or device to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water supplier and/or a service agency for assistance in controlling these situations. n ote : t o protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di- electric unions or couplings be installed on this water heater when connected to copper pipe. f i gure 4 shows the typical attachment of the water piping to the water heater. the water heater is equipped with 1/2 inch npt water connections. note : if using copper tubing, solder tubing to an adapter b e f o r e a t t a c h i n g t h e a d a p t e r t o t h e c o l d w a t e r i n l e t c onnection. do not solder the cold water supply line directly to the cold water inlet, it will harm the dip tube and damage the tank.
9 This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer. The valve is certified by a nationally recognized testing laboratory t h a t m a i n t a i n s p e r i o d i c i n s p e c t i o n o f p r o d u c t i o n o f l i s t e d equipment of materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, 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 less than a combination temperature and pressure relief valve certified as indicated in the above paragraph. The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. f o r safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve. Provide tubing so that any discharge will exit only within 6 inches (153 mm) above an adequate drain, or external to the building or structure. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), 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 unless a 6 inch air gap is provided. The relief valve must be allowed to discharge water in sufficient quantities, should circumstances demand, to prevent bodily injury, hazard to life, or property damage. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage. The Discharge Pipe: • Shall not be smaller in size than the outlet pipe size of the valve, o r have any reducing couplings or other restrictions. • Shall not be plugged or blocked. • Shall be of material listed for hot water distribution. • Shall be installed so as to allow complete drainage of both the t emperature-pressure relief valve, and the discharge pipe. • Shall terminate at an adequate drain or external to the building o r structure. • Shall not have any shut-off valve between the relief valve and t ank nor in the discharge pipe. The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot. If after manually operating the valve, it fails to completely r e s e t a n d c o n t i n u e s t o r e l e a s e w a t e r, i m m e d i a t e l y c l o s e the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one. f illin G the water heater N e v e r u s e t h i s w a t e r h e a t e r u n l e s s i t i s c o m p l e t e l y f u l l o f w a t e r.
