Removing the Old Water Heater
1. Turn "OFF" electrical supply to the water heater.
FIGURE!
2. Turn “OFF” the water supply to the water heater at the water shut-off valve or water meter.
FIGURE 2.
3. Attach a hose to the water heater drain valve and put the other end in a floor drain or outdoors. Open the water drain valve. Open a nearby hot water faucet which will relieve pressure in the water heater and speed draining.
The water passing out of the drain valve may be extremely hot.
To |
avoid |
being |
scalded, make |
sure all connections |
are tight |
and that the water flow is directed away from any person. |
|
||||
4. |
Check again to make sure the electrical supply |
is turned |
|||
|
“OFF” to the water heater. Then unplug the water heater |
||||
|
(cord |
set) |
or disconnect |
the electrical supply |
connection |
|
from the water heater junction box. |
|
|||
5a. If you have copper piping to the water heater, |
the two |
||
copper water pipes can be cut with |
a |
hacksaw |
|
approximately |
four inches away from where |
they |
connect |
to the water |
heater. This will avoid cutting off |
the pipes too |
|
short. Additional cuts can be made later if necessary. Disconnect the temperature-pressure relief valve drain line. When the water heater is drained, disconnect the hose from the drain valve. Close the drain valve. The water heater is now completely disconnected and ready to be removed.
5b. If you have galvanized pipe to the water heater, loosen the two galvanized pipes with a pipe wrench at the union in each line. Also disconnect the piping remaining to the water heater. These pieces should be saved since they may be needed when reconnecting the new water heater. Disconnect the temperature-pressure relief valve drain line. When the water heater is drained, disconnect the hose from the drain valve. Close the drain valve. The water heater is now completely disconnected and ready to be removed.
CAUTION
Mineral Buildup or Sediment May Accumulate
This causes the water heater to become much heavier than normal.
Ifspilled, could cause staining.
Mineral buildup or sediment may have accumulated in the old water heater. This causes the water heater to be much heavier than normal and this residue, ifspilled out, could cause staining.
Facts to Consider About the Location
You should carefully choose an indoor location for the new water heater, because the placement is a very important
consideration |
for |
the safety |
of the |
occupants in |
the building |
and for the |
most |
economical |
use of |
the appliance. |
This water |
heater is not intended for outdoor installation.
Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed.
• The location selected should be indoors as close to and as
centralized |
with the |
water piping system as possible. This |
|||
water |
heater, |
as well as all water heaters, will |
eventually |
||
leak. |
Do |
not |
install |
without adequate drainage |
provisions |
so water flow will not cause damage.
CAUTION
Property Damage Hazard
All water heaters eventually leak
Do not install without adequate drainage.
WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause
damage |
to |
the structure. When such locations cannot be |
avoided, |
a |
suitable drain pan should be installed under the |
water heater. Drain pans are available at your local Sears stores. Such drain pans must be piped to an adequate drain.
Water |
heater |
life depends upon |
water quality, |
water |
pressure |
and the environment in which |
the water heater is installed. |
||||
Water |
heaters |
are sometimes |
installed in |
locations |
where |
leakage may result in property damage, even with the use of a
drain pan piped |
to a drain. However, unanticipated damage |
can be reduced or |
prevented by a leak detector or water shut |
off device used in conjunction with a piped drain pan. These
devices are available from some plumbing |
supply wholesalers |
|
and retailers, and detect and react to leakage in various ways: |
||
• Sensors mounted in the drain pan that |
trigger |
an alarm or |
turn off the incoming water to the water |
heater |
when leakage |
is detected. |
|
|
Sensors mounted In the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater.
CAUTION
Installations in Residential Garages
Water heater must be located in a protective area.
INSTALLATION IN RESIDENTIAL GARAGES: The water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.
•The location selection must provide adequate clearances for servicing and proper operation of the water heater.
Insulation Blankets
Insulation |
blankets are |
available to |
the |
general |
public for |
external |
use on electric |
water heaters |
but |
are not |
necessary |
with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your water heater meets or exceeds the National Appliance Energy Conversation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions below. Failure |
to follow |
these instructions can result in fire, serious personal |
injury, or |
death. |
|
•Do not cover the temperature and pressure relief (T & P) valve with an insulation blanket.
•Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.
•Do obtain new warning and instruction labels for placement on the blanket directly over the existing labels.
Facts to Consider About the
Convertible Lower Element
The Upper Element (if a double element model) is a conventional 3800 watt element which only operates at its rated wattage on 240 volts. (See rating plate on the water heater).
The Lower Element of the water heater can be converted from operation at 3800 watts to 5500 watts on a 240 volt system.
Read and follow water heater warnings and instructions. If after reading these instructions in this manual, you do not understand any portion, call Sears Service Center.

or death.
Children, the elderly, and the physically or mentally disabled are at highest riskfor scald injury.
Feel water before bathing or showering.
Temperature limiting valves are available.
Read instruction manual for safe temperature setting.
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 |

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 |

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.
FIGURE?.
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 coid 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 ioss from the tank. Further reduction in heat ioss can be accompiished by insulating the hot water lines from the water heater.
FitT & 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.

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.
AWARNING
Explosion Hazard
Temperature-pressure relief valve must comply with ANSI 221.22 CSA4.4andASMEcode,
Properly sized temperature-relief valve must be installed in opening provided.
Can result in overheating and excessive tank pressure.
Can cause serious injury or death.
This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer.
The valve |
Is |
certified |
by a nationally recognized testing |
laboratory |
that |
maintains |
periodic inspection of production of |
listed equipment of materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21,22 • CSA 4.4, and the code requirements of ASME.
If replaced, |
the |
valve |
must meet |
the requirements of |
local |
|
codes, |
but |
not |
less |
than a combination temperature and |

paragraph.
The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (For electric heaters, watts x 3.412 equals Btu/hr input rate)
For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve.
