High Altitude; Insulation Blankets - Rheem Residential 40 Gallon Use & Care Manual

WARNING: If local
codes require external
application of insulation
blanket kits the
manufacturer's instructions
included with the kit must
be carefully followed.
Pressure Testing the Gas Supply System
The water heater and its manual gas
shut-off valve must be disconnected from
the gas supply piping system during any
pressure testing of that system at
pressures in excess of 1/2 psi (14" w.c.).

High Altitude

Ratings of gas appliances are based
on sea level operation. This water heater
is suitable and certified for use at high
altitudes. Refer to the altitude label on
the water heater for maximum allowable
installation altitude Please contact your
local distributor or place of purchase for a
high altitude model.

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.
The water heater must be isolated from
the gas piping system by closing the
manual gas shut-off valve during any
pressure testing of the gas supply piping
at pressures equal to or less than
1/2 psi (14" w.c.).
WARNING: Failure to install a
water heater suitable for the altitude at
the location it is intended to serve, can
result in improper operation of the
appliance resulting in property damage
and/or, producing carbon monoxide
gas, which could result in personal
injury, or death.
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. as this will interfere with
the safe operation of the water heater
and venting system.
Do not cover the burner access door,

jacket door, gas control (thermostat)/gas
valve or pressure and temperature relief
valve.
