WARNING

At the time of manufacture this water heater was provided with a
combination temperature-pressures relief valve certified by a
nationally recognized testing laboratory that maintains periodic
inspection of production of listed equipment or materials, as
meeting the requirements for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, and the current
edition of ANSI Z21.22 • CSA 4.4 and the code requirements of
ASME. If replaced, the valve must meet the requirements of local
codes, but not less than a combination temperature and pressure
relief valve certified as meeting the requirements for Relief Valves
and Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22 • CSA 4.4 by a nationally recognized testing
laboratory that maintains periodic inspection of production of
listed equipment or materials.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 lbs./sq. in.) and a discharge capacity not less than the
water heater input rate as shown on the model rating plate.
(Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr.
rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying with ANSI Z21.22 •
CSA 4.4 and ASME, may require a valve model different from the
one furnished with the water heater.
Compliance with such local requirements must be satisfied by the
installer or end user of the water heater with a locally prescribed
temperature-pressure relief valve installed in the designated
opening in the water heater in place of the factory furnished valve.
For safe operation of the water heater, the relief valve must not be
removed from it’s designated opening or plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designated for the relief valve.
Position the valve downward and provide tubing so that any
discharge will exit only within 6 inches above, or at any distance
below the structural floor. Be certain that no contact is made with
any live electrical part. The discharge opening must not be
blocked or reduced in size under any circumstances. Excessive
length, over 30 feet, or use of more than four elbows can cause
restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
drain unless a 6” air gap is provided. To prevent bodily injury,
hazard to life, or property damage, the relief valve must be
allowed to discharge water in quantities should circumstances
demand. If the discharge pipe is not connected to a drain or other
suitable means, the water flow may cause property damage.
The Discharge Pipe:

• Must not be smaller in size than the outlet pipe size of the valve,

or have any reducing couplings or other restrictions.

• Must not be plugged or blocked.
• Must be of material listed for hot water distribution.
• Must be installed so as to allow complete drainage of both the

temperature-pressure relief valve, and the discharge pipe.

• Must terminate at an adequate drain.
• Must not have any valve between the relief valve and tank.

WARNING

Improper installation, adjustment, alteration, service or
maintenance can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. Refer to this manual

WARNING

HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a
temperature which will satisfy clothes washing, dish
washing, and other sanitizing needs can scald and
permanently injure you upon contact. Some people are
more likely to be permanently injured by hot water than
others. These include the elderly, children, the infirm, or
physically/mentally handicapped. If anyone using hot
water in your home fits into one of these groups or if
there is a local code or state law requiring a certain
temperature water at the hot water tap, then you must
take special precautions. In addition to using the lowest
possible temperature setting that satisfies your hot water
needs, a means such as a mixing valve, should be used
at the hot water taps used by these people or at the water
heater. Mixing valves are available at plumbing supply or
hardware stores. Follow manufacturers instructions for
installation of the valves. Before changing the factory
setting on the thermostat, read the “Temperature
Regulation” section in this manual.

WARNING

Do not use this appliance if any part of it has been under
water. An electrical short or malfunction could occur.
The water heater should be replaced.

WARNING

INSULATING JACKETS: When installing an external water
heater insulation jacket on an electric water heater:

• DO NOT cover the temperature-pressure relief valve.
• DO NOT put insulation over the access covers or any

access areas.

• DO NOT remove operating instructions, and safety

related warning labels and materials affixed to the water
heater.

• DO obtain new warning and instruction labels from Maytag for

placement on the jacket directly over the existing labels.

Safety Instructions

WARNING

HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure
the electrical supply to the water heater is turned “OFF”.
Failure to do this could result in DEATH, SERIOUS
BODILY INJURY, OR PROPERTY DAMAGE.
