Installing the New Water Heater
Water Piping
WARNING
HOTTER WATER CAN SCALD: Water heaters are intend- ed to produce hot water. Water heated to a temperature which will satisfy 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 physical- ly/mentally handicapped. 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 tem- perature setting that satisfies your hot water needs, some type of tempering device, 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 at plumbing supply or hardware stores. Follow manufacturers instruc- tions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that dielec- tric unions or couplings be installed on this water heater when connected to copper pipe.
The illustration shows the attachment of the water piping to the water heater. The water heater is equipped with 3/4 inch water connections.
NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet con- nection. Do not solder the cold water supply line directly to the cold water inlet or it will harm the dip tube.
NOTE: This water heater is insulated to minimize heat loss from the tank. Further reduction in heat loss can be accomplished by insulating the hot water lines from the water heater.
