For increased energy efficiency,
some water heaters have been sup-
plied with
two 24 in. (61 cm) long sections of
pipe insulation.
Please install the insulation, accord-
ing to the illustrations above, that
best meets your requirements.

Hot and Cold Pipe Insulation Installation
Insulation Blankets
Insulation blankets, available to
the general public, for external use
on gas water heaters are not neces-
sary. 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 stand-
by 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 manufactur-
er) into, onto or in conjunction with
the water heater. The use of unau-
thorized 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 unau-
thorized 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 relo-
cate them on the exterior of insu-
lation blanket.

Do not apply insulation to the top
of the water heater. This will inter-
fere 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
area where the Flammable Vapor
Sensor is located. This area must
be unobstructed so as not to
restrict air flow to the sensor.

Inspect the insulation blanket fre-
quently making certain it has not
sagged and it is not restricting the
air flow to the Flammable Vapor
sensor located around the lower
perimeter of the water heater jack-
et. 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.
