Installing the water heater. The location chosen for the water heater must take into consideration the following: Local Installation Regulations This water heater must be installed in accordance with these instructions, local codes, utility codes, utility company requirements or, in the absence of local codes, the latest edition of the National Electrical Code.

Installing the water heater. Thermal Expansion Determine if a check valve exists in the inlet water line. It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water system.” A cold water inlet line with no check valve or back flow prevention device is referred to as an “open” water system.

Installing the water heater. Condensation Condensation can form on the tank when it is first filled with water. Condensation might also occur with a heavy water draw and very cold inlet water temperature. This condition is not unusual, and will disappear after the water becomes heated. If, however, the condensation continues, examine the piping and fittings for possible leaks. Additional information on this subject may be found at www.rheem.com under “Library”.

Insulation Blankets WARNING: If local codes require external application of insulation blanket kits the manufacturer’s instructions included with the kit must be carefully followed. Insulation blankets, available to the general public, for external use on electric water heaters are not necessary. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters.

Installing the water heater. Relief Valve Insulation Installation CAUTION: Ensure the T&P Valve opening is not obstructed by the insulation. HO R E L T I V A L V E E F CO LD Typical top connection arrangement Typical side connection arrangement For increased energy efficiency, some water heaters have been supplied with a 2-3/8” section of pipe insulation. Slip the insulation cover over the T&P Valve through the center hole and align the hole in the side with the opening of the T&P Valve.

Installation Checklist A. Water Heater Location ❑ Close to area of heated water demand. ❑ Indoors and protected from freezing temperatures. ❑ Area free of flammable vapors. ❑ Provisions made to protect area from water damage. ❑ Sufficient room to service heater. B. Water Supply ❑ Water heater completely filled with water. ❑ Air purged from water heater and piping. ❑ Water connections tight and free of leaks. C.

Operating the water heater. CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, 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.
PAGE 13
Water Temperature Setting DANGER: There is a hot water scald potential if the thermostat is set too high. Households with small children, disabled, or elderly persons may require a 120°F or lower thermostat setting to prevent contact with HOT water. The temperature of the water in the water heater can be regulated by setting the temperature dial of the adjustable surface mounted thermostat(s) located behind the jacket access panel(s). Dual element heaters have two thermostats.

Care and cleaning of the water heater. Draining the Water Heater CAUTION: Shut off power to the water heater before draining water. DANGER: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage. In order to drain the water heater, turn off the cold water supply.
