Installing the water heater.
WARNING: If local
codes require external
application of insulation
blanket kits the
manufacturer's
instructions included
with the kit must be
carefully followed.
NOTICE: If pipe
insulation is used,
ensure that the
thickness does not
exceed ½". Insulation
thicker than ½" can
interfere with the

Insulation Blankets

Insulation blankets, available to the
general public, for external use on gas
water heaters are not necessary. The
purpose of an insulation blanket is to
reduce the standby heat loss encountered
with storage tank heaters. This 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.
The manufacturer's warranty does not
cover any damage or defect caused by
installation, attachment or use of
any type of energy saving or other
unapproved devices (other than those
authorized by the manufacturer) into,
onto or in conjunction with the water
heater. The use of unauthorized energy
saving devices may shorten the life of the
water heater and may endanger life and
property.
The manufacturer disclaims any
responsibility for such loss or injury
resulting from the use of such
unauthorized devices.
Hot and Cold Pipe Insulation Installation
Typical vertical piping arrangement
For increased energy efficiency, some
water heaters have been supplied with
two 24" sections of pipe insulation.
CAUTION: If local codes require
the application of an external
insulation blanket to this water
heater, pay careful attention to the
following so as not to restrict the
proper function and operation of
the water heater:
Do not cover the operating or warning
●
labels attached to the water heater
or attempt to relocate them on the
exterior of insulation blanket.
Do not apply insulation to the top

of the water heater. This will interfere
with the safe operation of the blower
assembly.
Do not cover the burner access door,

jacket door, gas control (thermostat)/
gas valve or pressure and temperature
relief valve.
 Do not apply insulation to the bottom
of the water heater or the area where
the combustion air inlet openings and
Flammable Vapor Sensor are located.
This area must be unobstructed so as
not to restrict combustion air flow to
the burner or operation of the sensor.
Inspect the insulation blanket frequently

making certain it has not sagged
and it is not restricting the air flow
to the combustion air inlet openings
(perforation holes) or the Flammable
Vapor sensor located around the lower
perimeter of the water heater jacket.
This could result in an unsafe operating
condition.
