Water Piping

HOTTER WATER CAN SCALD: Water heaters are intended 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 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, a means such as a mixing valve, shall 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 thermostat, read the “Temperature Regulation” section in this manual.

See Figure 8 for mixing valve usage.

meter with a check valve, etc... in the cold water supply; means must be provided to control thermal expansion. Contact the local utility or Sears Service Center on how to control this situation.

NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the water connections. Do not solder the water supply lines directly to the connections. It will harm the fittings on the water heater.

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.

1.Look at the side of the water heater. The hot water outlet is marked hot. Put two or three turns of teflon tape around the threaded end of the threaded-to-sweat coupling and around the 3/4” threaded nipple. Using flexible connectors, connect the hot water pipe to the hot water outlet of the water heater.

2.Look at the side of the water heater. The cold water inlet is marked cold. Put two or three turns of teflon tape around the threaded end of the threaded-to-sweat coupling and around the 3/4” threaded nipple. Using flexible connectors, connect the cold water pipe to the cold water inlet of the water heater.

Figure 9 shows the attachment of the water piping to the water heater. The water heater is equipped with 3/4” water connections.

If a water heater is installed in a closed water supply system; such as one having a back-flow preventer, check valve, water

NOTE: Your 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.
