Removing the Old Water Heater
4. Attach a hose to the water heater drain
valve and put the other end in a floor
drain or outdoors. Open the water
heater 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,
see Figures 2 and 5.
Disconnect the vent pipe from the blower assembly where it connects
to the water heater. In most installations the vent pipe can be lifted off
after any screw or other attached devices are removed. Make sure
existing vent complies with maximum and minimum vent lengths on
page 17.
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, see Figures. This will
avoid cutting off 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.
1. Turn “OFF” the gas supply to the water
heater.
If the main gas line Shut-off valve
serving all gas appliances is used, also
shut “OFF” the gas at each appliance.
Leave all gas appliances shut “OFF”
until the water heater installation is
completed, see Figures 2 and 3.
2. Turn “OFF" the water supply to the
water heater at the water shut off
valve or water meter. Some
installations require that the water be
turned off to the entire house, see
Figures 2 and 4.
Check again to make sure the gas supply is “OFF” to the water
heater. Then disconnect the gas supply connection from the gas
control valve.
FIGURE 6.
If you have galvanized pipes 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, see Figure 7.
These pieces should be saved since they may be needed when
reconnecting the new water heater. Disconnect the temperaturepressure 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. 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, if spilled out, could cause staining.
FIGURE?.
FACTS TO CONSIDER ABOUT THE LOCATION
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 for use in manufactured (mobile) homes
or outdoor installation.
Whether replacing an old water heater or putting the water heater in a
new location, the following critical points must be observed:
1, Select a location indoors as close as practical to the vent terminal or
location to which the water heater vent piping is going to be connected,
and as centralized with the water piping system as possible.
2. Selected location must provide adequate clearances for servicing
and proper operation of the water heater.
CAUTIO
Property Damage Hazard
• Allwaterheaterseventuallyleak,
• Do not install without adequate drainage.
installation of the water heater must be accomplished in such a manner
that if the tank or any connections should leak, the flow will not cause
damage to the structure. For this reason, it is not advisable to install the
wafer heater in an attic or upper floor. When such locations cannot be
avoided, a suitable drain pan should be installed under the water heater.
Drain pans are available at your local hardware store. Such a drain pan
must have a minimum length and width of at least 2" (5.1 cm) greater than
the water heater dimensions and must be piped to an adequate drain.
The pan must not restrict combustion air flow.

Awarnin
Fire or Explosion Hazard I
Do not store or use gasoline or other flammable vapors and
liquids In the vicinity of this or any other appliance.
Avoid all ignition sources if you smell LPgaa.
Do not expose water heater control to excessive gas
pressure.
Use only gas shown on rating plate.
Maintain required clearances to combustibles.
Keep ignition sources away from faucets after extended
period of non-use.
Read instruction manual before
installing, using or servicing
water heater.
Also, the water heater must be located and/or protected so it is not
subject to physical damage by a moving vehicle.
w
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 wafer 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 differentia! between the cold water and hot wafer pipes
connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater while at
the same time shutting off its water supply.
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS)
ARE LIKELYTO BE PRESENT OR STORED (GARAGES, STORAGEAND
UTILITY AREAS, ETC.): Flammable liquids (such as gasoline, solvents,
propane (LP or butane, etc.) and other substances (such as adhesives,
etc.) emit flammable vapors which can be ignited by a gas water heater's
hot surface igniter or main burner. The resulting flashback and fire can
cause death or serious burns to anyone in the area. This water heater is
equipped with a FV sensor for detecting the presence of flammable
vapors, see Figure 8. When the sensor detects those vapors, the unit
will shut down and not operate. Should this happen, please refer to the
troubleshooting guide on pages 29-30. Even though this water heater is
a flammable vapors ignition resistant water heater and is designed to
reduce the chances of flammable vapors being ignited, gasoline and
other flammable substances should never be stored or used in the same
vicinity or area containing a gas water heater or other open flame or
spark producing appliance.
AWARNING
Fire Hazard
For continued protection against
riskoffire:
• Do not install water heater on
carpeted floor,
• Do not operate water heater if
flood damaged.
This wafer heater must not be installed directly on carpeting. Carpeting
must be protected by metal or wood panel beneath the appliance extending
beyond the full width and depth of the appliance by at least 3" (7,6 cm) in
any direction, or if the appliance is installed in an alcove or closet, the
entire floor must be covered by the panel. Failure to heed this warning
may result in a fire hazard.
Awarnin
Fire or Explosion Hazard
Read instruction manual before installing,
using or servicing water heater.
• Improper use may result in fire or
explosion,
• Maintain required clearances to
è
Minimum clearances between the water heater and combustible
construction are 0 inch at the sides and rear, 5" (12.7 cm) from the front
combustibles.
and 12" (30.5 cm) from the fop. (Standard clearance.) If clearances
stated on the heater differ from standard clearances, instaii water heater
according to clearances stated on the heater.
Adequate clearance for servicing this appliance should be considered
before installation, such as changing the anodes, etc.
A minimum clearance of 5" (12.7 cm) must be allowed for access to
replaceable parts such as the thermostats, drain valve and relief valve.
When installing the heater, consideration must be given to proper location.
Location selected should be as dose to the wall as practicable and as
centralized with the water piping system as possible.
A WARNING
flammable in many cases, will also react to form corrosive hydrochloric
acid when exposed to the combustion products of the water heater.
The results can be hazardous, and also cause product failure.
INSULATION BLANKETS
Insulation blankets are available to the general publicfor external use
on gas water heaters but are not necessary with Kenmore products.
The purpose of an insulation blanket is to reduce the standby heat loss
encountered with storage tank heaters. Your Kenmore wafer heater
meets or exceeds the National Appliance Energy Conservation Act
standards with respect to insulation and standby loss requirements,
making an insulation blanket unnecessary.
AWARNIN
Breathing Hazard - Carbon Monoxide Gas
• Do not obstruct water heater air intake
with insulating blanket.
• Gas and carbon monoxide detectors
are available.
• Install water heater in accordance with
the instruction manual.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Breathing Hazard - Carbon Monoxide Gas
• Install wafer heater in accordance with
the instruction manual and NFPA54.
mmmr
• To avoid injury, combustion and
ventilation air must be taken from
outdoors.
»«N
• Do not place chemical vapor emitting
products near water heater.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
A gas water heater cannot operate properly without the correct amount
of air for combustion. Do not install in a confined area such as a closet,
unless you provide air as shown in the “Facts to Consider About the
Location” section. Never obstruct the flow of ventilation air. If you
have any doubts or questions at all, calf your gas supplier. Failure to
provide the proper amount of combustion air can result in a fire or
explosion and cause death, serious bodily injury, or property damage.
Should you choose to apply an insulation blanket to this heater, you
should follow these instructions (For identification of components
mentioned below, see Figure 1). Failure to follow these instructions
can restrict the air flow required for proper combustion, potentially
resulting in fire, asphyxiation, serious personal injury or death.
• Do not apply insulation to the top of the water heater, as this will
interfere with safe operation of the blower assembly.
• Do not cover the outer door, thermostat or temperature & pressure
relief valve.
• Do not allow insulation to come within 2" (5.1 cm) of the floor to
prevent blockage of combustion air flow to the burner,
• 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 from Sears
for placement on the blanket directly over the existing labels.
• Do inspect the insulation blanket frequently to make certain it
does not sag, thereby obstructing combustion airflow.

in unconfined spaces in buildings, infiitration maybe adequate to provide
air for combustion, ventilation and dilution of flue gases. However, in
buildings of tight construction (for example, weather stripping, heavily
insulated, caulked, vapor barrier, etc.), additional air may need to be
provided using the methods described in “Combustion Air and Ventilation
for Appliances Located in Confined Spaces.”
If this water heater will be used in beauty shops, barber shops, cleaning
establishments, or self-service laundries with dry cleaning equipment,
it is imperative that the water heater or water heaters be installed so
that combustion and ventilation air be taken from outside these areas.
