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 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 thermostat,
read the Temperature Regulation section in this manual.
See Figure 7 (below) for mixing valve usage.

VALVE WATER HEATER
FIGURE 7.
Figure 8 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 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.
CAUTION
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 service agency.
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.
2. 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.
T & P Valve and Pipe Insulation______________
1. Locate the temperature and pressure relief valve on the water
heater (also known as a T&P relief valve). See Figure 9.
2. Locate the slit running the length of the T&P relief valve
insulation.
3. 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
