Pipe Insulation - Rheem PowerVent Series Use & Care Manual

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" (1.3 cm).
Insulation thicker than
½" (1.3 cm) can interfere
with the Blower Assembly
Dilution Air Holes.

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.

For increased energy efficiency, some
water heaters have been supplied with
two 24"(61 cm) 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 Vapour 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
Vapour sensor located around the lower
perimeter of the water heater jacket.
This could result in an unsafe operating
condition.
