For increased energy efficiency, some
water heaters have been supplied with
two 24” sections of pipe insulation.
Please install the insulation, according
to the illustrations above, that best meets
your requirements.

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