Kenmore 153.33443 - Manual (Page 13)

This water heater shall not be connected to any heating systenns
or component(s) used with a non-potable water heating
appliance.
All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall
not be introduced into this system.
Water supply systems may, because of such events as high
line pressure, frequent cut-offs or the effects of water hammer
among others, have installed devices such as pressure reducing
valves, check valves, back flow preventers, etc. to control these
types of problems. When these devices are not equipped with
an interna! by-pass, and no other measures are taken, the
devices cause the water system to be closed. As water Is heated,
it expands (thermal expansion) and closed systems do not allow
for the expansion of heated water.
The water within the water heater tank expands as it is heated
and increases the pressure of the water system. If the relieving
point of the water heater's temperature-pressure relief valve Is
reached, the valve will relieve the excess pressure. The
temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This is an unacceptable
condition and must be corrected. It is recommended that any
devices installed which could create a closed system have a
by-pass and/or the system have an expansion tank to relieve
the pressure built by thermal expansion in the water system.
Refer to the Thermal Expansion section under Troubleshooting
Guide or contact local plumbing authority or local Sears Service
Center on how to control this situation.
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. * •
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 Sears Service Center.
Figure 15 shows the typical attachment of the water piping to
the water heater. The water heater Is equipped with 3/4” NPT
water connections.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the cold water inlet
connection. Do not solder the cold water supply line directly
to the cold water inlet, it will harm the dip tube and damage
the tank.
• Look at the top cover of the water heater. The 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” NPT threaded nipple. Using
flexible connectors, connect the hot water pipe to the hot
water outlet on the water heater.
Look at the top 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” NPT threaded nipple. Using
flexible connectors, connect the cold water pipe to the cold
water inlet of the water heater.
NOTE: This water heater is super 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.
