GENERAL INFORMATION This storage unit must be installed in accordance with local codes. In the absence of local codes, install this storage unit in accordance with the N.E.C. Reference Book (latest edition). The warranty for this storage unit is in effect only when the storage unit is installed, adjusted, and operated in accordance with these Installation and Operating Instructions.
General Information continued- IMPORTANT Before proceeding, please inspect the storage unit and it’s components for possible damage. DO NOT install any damaged components. If damage is evident, please contact the supplier where the storage unit was purchased or the manufacturer listed on the rating plate for replacement parts. Massachusetts Code Compliance: If total tank volume exceeds 120 gallons and/or recovery rate is 200,000 btu/hr or greater, all system components shall be ASME.
INSTALLATION Locating The Storage Unit WARNING To avoid damage or injury, there shall be no materials stored against the storage unit and proper care shall be taken to avoid unnecessary contact (especially by children) with the storage unit. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF THIS STORAGE UNIT OR ANY LOCATION FROM WHICH FUMES COULD REACH THE STORAGE UNIT.
Locating The Storage Unit continued- This storage unit must be located in an area where leakage of the tank or water line connections and the combination temperature and pressure relief valve will not result in damage to the area adjacent to the storage unit or to lower floors of the structure. When such locations cannot be avoided, a suitable drain pan must be installed under the storage unit. The drain pan must have a minimum length and width of at least 4 in. (10.
Water Connections NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting the main water supply valve, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the storage unit. After the pressure has been relieved, close the faucet. The fittings at the circulating connections and the hot water outlet are dielectric waterway fittings with 2” NPT tapered male threads.
Water Connections continued- WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure 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 Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.
Water Connections continued- WARNING Hydrogen gas can be produced in a hot water system served by this storage unit 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.
Water Connections continued- 10
GENERAL OPERATION CAUTION Under certain conditions, water in this water heater/storage unit may become excessively hot. It is recommended that an ASSE approved mixing valve may be installed in the outlet line to reduce the risk of scald injury by preventing point of discharge water temperatures in excess of 140°F (60°C). 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).
MAINTENANCE IMPORTANT The storage unit should be inspected at a minimum of annually by a qualified service technician for damaged components. DO NOT operate this storage unit if any part is found damaged. The storage unit should be drained 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 storage unit at least once a month through the drain valve until the water runs clear.
Maintenance continued- 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. 3. Monthly, drain off a gallon of water from the storage unit to remove silt and sediment. WARNING! THIS WATER MAY BE HOT. 4. A combination sacrificial anode rod/hot water outlet nipple has been installed to extend tank life.
Maintenance continued- Contact your local plumbing supplier or plumbing professional for replacement parts or contact the company at the address displayed on the rating plate of the storage unit. For faster and better service, please provide the part name, model, and serial number(s) of the storage unit(s) when ordering parts. READ THE WARRANTY FOR A FULL EXPLANATION OF THE LENGTH OF TIME THAT PARTS AND THE WATER HEATER ARE WARRANTED. Manufactured under one or more of the following U.S. Patents: RE.
