Property
Damage
Hazard
° Avoid water
heater damage.
o Install thermal
expansion
tank or device
if necessary.
o Contact
qualified
installer
or service
agency.
NOTE:
Expansion
tanks
are preocharged
with
a 40 psi air
charge.
Bfthe inlet water
pressure
is higher
than
40 psi, the
expansion
tank's
air pressure
must
be adjusted
to match
that pressure,
but must
not be higher
than
80 psi.
Water
supply
systems
may,
because
of such
events
as high
line pressure,
frequent
cut-offs,
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 internal
by-pass,
and no other measures
are
taken,
the devices
cause
the water
system
to be close&
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
wil!
relieve
the
excess
pressure.
The
temperatureopressure
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.
Thermal
expansion
tanks
are
available
from
Sears
stores
and through
the Sears
Service
Centers.
Contact
the local
plumbing
inspector,
water
supplier
and/or
the Sears
Service
Center
for assistance
in controlling
these
situations.

In each
glass-lined
water
heater
there
is installed
one anode
rod (see
parts
section)
for corrosion
protection
of the tank.
Certain
water
conditions
will cause
a reaction
between
this
rod and the water.
The
most
common
complaint
associated
with the anode
rod is one of a "rotten
egg smell'L
This odor
is
derived
from hydrogen
sulfide
gas dissolved
in the wateE
The
smell
is the result of four factors
which
must
all be present
for
the odor to develop:
A A concentration
of sulfate
in the supply
water.
B. Little or no dissolved
oxygen
in the water.
*Highest
recorded
inlet water
pressure
in a 24 hour period
or
regulated
water
pressure.
C. A sulfate
reducing
bacteria
within
the water
heater.
(This
harmless
bacteria
is nomtoxic
to humans.)
