temperature-pressurereliefvalve is not intended for the

constant relief of thermal expansion. This is an unacceptable

condition and must be corrected. It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expansion tank to relieve

the pressure built by thermal expansion in the water system. Refer to the Thermal Expansion section under Troubleshooting Guide or contact local plumbing authority or local Sears Service Center on how to control this situation.

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.

Property Damage Hazard

• Avoid water heater damage.

-Install thermal expansion tank if necessary.

• Do not apply heat to cold water inlet.

• Contact qualified installer or Sears Service Center.

Figure 15 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4" NPT water connections.

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.

NOTE: If using copper tubing, solder tubing to an adapter

before attaching the adapter 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.

Look at the top cover of the water heater. The 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 both ends of the 3/4" NPT threaded nipple. Using

flexible connectors, connect the hot water pipe to the hot water outlet on the water heater.

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.
