NOTE: Before making any connections to the cold water inlet or hot water outlet, insure that all piping is clean and free of material or scale. This can usually be accomplished by “blowing out the pipe.” Any foreign material or scale entering the water heater can adversely affect operation and performance.

NOTE: When using copper tubing, solder tubing to an adapter before attaching to the threaded nipple connection provided on the water heater. Soldering directly to the threaded connection may harm a lining in the nipple or damage the tank lining.

Inlet and Outlet Connections

For ease of service, install unions on the cold water inlet and hot water outlet of the water heater. The cold water inlet connection is located on the lower right side of the water heater. A manual shutoff valve should be installed upstream on the cold water source as an isolation device. The hot water outlet connection is located on the top center of the water heater. A manual shutoff valve should be installed downstream on the hot water outlet source as an isolation device in case the water heater must be disconnected from the system.

STORAGE TANK

This appliance uses a glass lined steel tank to store the heated water for use. The storage tank is constructed in accordance with the ASME Boiler and Pressure Vessel Code requirements, stamped and registered with the National Board of Boiler and Pressure Vessel Inspectors. The tank is furnished with threaded connections for cold water inlet, hot water outlet, a relief valve and a drain connection. The storage tank has a hand hole for ease of inspection, cleanout and service. An optional manhole may be specified for greater ease of inspection. The interior of the storage tank is glass lined and fired to 1600˚F

(871˚C) to insure a molecular fusing of glass and steel to protect the steel base metal against corrosion . A magnesium anode(s) is standard to help prevent dissipation of the tank material by electrolytic action.

RELIEF VALVE

This water heater is supplied with a temperature and pressure relief valve(s) sized in accordance with ASME Boiler and Pressure Vessel Code, Section IV. Some water heaters may be supplied with an optional pressure only relief valve. The relief valve(s) is installed in the vertical position and mounted in the tapping provided in the storage tank. No valve is to be placed between the relief valve and the water heater. To prevent water damage, the discharge from the relief valve must be piped to a suitable floor drain for disposal when relief occurs. No reducing couplings or other restrictions shall be installed in the discharge line. The discharge line shall allow complete drainage of the valve and line. Relief valves should be manually operated at least once a year. A relief valve that fails to completely reseat and continues to discharge water must be immediately replaced with a new, properly sized, temperature and pressure relief valve.

CAUTION: Avoid contact with hot discharge water. Insure that no one is in front of or around the relief valve discharge line. Make sure that the extremely hot water manually discharged from the relief valve will not cause bodily injury or property damage.

THERMAL EXPANSION OF WATER

A relief valve that discharges periodically may be due to thermal expansion in a closed system. A water heater installed in a closed system, such as one with a backflow preventer or check valve installed in the cold water supply, shall be provided with means to control expansion. Contact the water supplier or local plumbing inspector on how to correct this situation.

DO NOT plug or cap the relief valve.
