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 top cover 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 both ends of the 3/4" threaded nipple. Using flexible
connectors, connect the hot water pipe to the hot water outlet
of the water heater.

Look at the top cover 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 both ends of the 3/4" threaded nipple. Using flexible
connectors, 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 8 shows the attachment of the water piping to the
water heater. The water heater is equipped with 3/4" water
connections.
Ifa water heater is installed in a closed water supply system; such
as one having a back-flow preventer, check valve, water 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 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.

& P Valve and Pipe Insulation
Locate the temperature and pressure relief valve on the water
heater (also known as a T&P relief valve). See Figure 9.
Locate the slit running the length of the T&P relief valve
insulation.
Spread the slit open and fit the insulation over the T&P relief
valve. See Figure 9. Apply gentle pressure to the insulation
to ensure that it is fully seated on the T&P Relief Valve. Once
seated, secure the insulation with duct tape, electrical tape, or
equivalent. IMPORTANT: The insulation and tape must not
