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
