eventually leak after a nextended period o ftime. Also any extemal
plumbing leak, i ncluding those fromimproper installation, may
cause e arly f ailure o fthetank due tocorrosion ifnotrepaired. If
the homeowner isuncomfortable with making therepair aqualified
technician should b econtacted. Asuitable metal drain pan should
beinstalled under the water heater asshown b elow, tohelp protect

climates, it isrecommended that t hedrain pipe beterminated at

CAUTION: When making pilot holes in the water
heater itself, ensure that you drill only the outer jacket.
Also, to prevent leaks in the metal drain pan, seal each drill
location with a heavy bead of silicone sealant.
Secure the top of the water heater with the provided bracket
and screws or install other acceptable means of support
(e.g., support strap).

Water heater life depends upon water quality, water usage,
water temperature 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 metal 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 metal 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 metal drain pan that trigger an
alarm or turn off the incoming water to the water heater
when water is detected.
• Sensors mounted in the metal 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.
• Devices that wilt turn off the gas supply to a gas water
heater while at the same time shutting off its water supply.
Securing Water Heater to Floor and Wall
The water heater must be secured to the floor and to the wall
of the enclosure as described below. See also "Enclosure
Installation."
After properly locating the water heater, fasten it to the
floor with the brackets and screws that were provided
(Figure 9). Simply pre-dritt each screw location in the
metal drain pan and water heater jacket with a 118" drill bit.
Because of installation variances, these brackets can be
located at any points around the circumference of the jacket.
However, they should be spaced apart at equal distances.
Insulation blankets available to the general public for external
use on gas water heaters are not necessary with Kenmore
products. The purpose of an insulation blanket is to reduce the
standby heat toss encountered with storage tank heaters. Your
Kenmore water heater meets or exceeds the National Appliance
Energy Conservation Act standards with respect to insulation
and standby loss requirements, making an insulation blanket
unnecessary.

Breathing Hazard - Carbon Monoxide Gas
•= _':'1:°_:- oo
I
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
• 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.
'_ WARNING
Should you choose to apply an insulation blanket to this
heater, you should follow these instructions. (See Figure 1
for identification of components mentioned below). 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 draft hood.
Do not cover the outer door, thermostat or temperature &
pressure relief valve.
• Do not allow insulation to come within 2" (50.8 mm) 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.
