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 on page 9 for mixing valve usage.
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
NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the water inlet connection. Do not solder the water supply lines directly to the cold water inlet. It will harm the dip tube and damage the tank.
NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that
1.Look at the upper pipe nipple on the water heater. The water outlet is marked hot. Connect the hot water pipe to the hot water outlet of the water heater.
2.Look at the lower pipe nipple on the water heater. The cold water inlet is marked cold. Connect the cold water pipe to the cold water inlet of the water heater.
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.
FIGURE 9.
T & P Valve and Pipe Insulation
Remove insulation for T & P valve and pipe connections from carton.
Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the top cover of the heater.
Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
