Installing the New Water Heater (cont’d)
Water Piping
WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a tem- perature which will satisfy clothes washing, dish wash- ing, and other sanitizing needs can scald and perma- nently injure you upon contact. Some people are more likely to be permanently injured by hot water than oth- ers. These include the elderly, children, the infirm, or physically/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 temperature 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 instructions for installation of the valves. Before changing the factory setting on the ther- mostat, read the “Temperature Regulation” section.

WARNING
This water heater shall not be connected to any heating systems or component(s) previously used with a non- potable water heating appliance.
If a water heater is installed in a closed water supply sys- tem; such as one having a
NOTE: To 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.
NOTE: This water heater is super 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.
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 adaptor to the cold water inlet connection. Do not solder the cold water supply line directly to the cold water inlet. It will harm the dip tube and damage the tank.
WATER PIPING PRESSURE TEST
This section is only for the manufacturer installing the water heater when the installation is to comply with H.U.D. Standards.
When testing the water ways, H.U.D. Standards state: “Water distribution system. All water piping in the water distribution system shall be subjected to a pres- sure test. The test shall be made by subjecting the sys- tem to air or water at 100 psi for 15 minutes without loss of pressure. When air pressure is used, the water heater shall not be connected during the test.”
WARNING
If the water piping system is to be air pressure tested, the water heater must be disconnected from the water piping system. Failure to disconnect the water heater during air pressure testing of the water piping system could result IN DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
