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 latest edition of ANSI Z21.22 and the code require-
&WARNING

If replaced,
the not
valve
must meet
the
nation 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 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 Ibs./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 3415 equal
BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the
use of a temperature-pressure relief valve complying
with ANSI Z21.22 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 rehef 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.Excessivelength, 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 provic[ed. 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 notbe 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.
|WATER HEATERS EQUIPPED FOR ONE TYPE GAS
|ONLY: This water heater is equipped for one type
gas only. Check the model rating plate near the gas
control valve for the correct gas. DO NOT USE THIS
WATER HEATER WITH ANY GAS OTHER THAN THE
ONE SHOWN ON THE MODEL RATING PLATE. Failure
to use the correct gas can cause problems which can
result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts
consult your gas supplier or local utility,
AWARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELYTO BE PRESENTOR STORED
(GARAGES, STORAGE, AND UTILITY AREAS, ETC):
I Flammable liquids (such as gasoline, solvents, propane
(LP) or butane, etc.), all of which emit flammable
vapors, may be improperly stored or used in such
areas. The gas water heater pilot light or main burner
can ignite such vapors, The resulting flashback and fire
can cause death or serious burns to anyone in the
area, as well as property damage,
If installation in such areas is your only option, then
the installation must be accomplished in a way that
the pilot flame and main burner flame are elevated
from the floor at least 18 inches, While this may reduce
the chances of flammable vapors from a floor spill
being ignited, gasoline and other flammable substances should never be stored or used in the same
room or area containing a gas water heater or other
open flame or spark producing appliance,
NOTE: Flammable vapors may be drawn by air currents
from other areas of the structure to the appliance,
AWARNING
If this water heater will be used in beauty shops,
barber shops, cleaning establishments, or self-service laundries with dry cleaning equipment,
it is
imperative that the water heater or water heaters
be installed so that combustion and ventilation air
be taken from outside these areas. Refer to the
"Locating The New Water Heater" section of this
manual and also the latest edition of the National
Fuel Gas Code, ANSI Z223.1, also referred to as NFPA
54 for specifics provided concerning air required,

Safety Instructions
AWARNING
AWARNING
A gas water heater cannot operate properly without
the correct amount of air for combustion. Do not
install in a confined area such a closet, unless you
provide air as shown in the "Locating The New
Water Heater" section. Never obstruct the flow of
ventilation air. If you have any doubts or questions
at all, call your gas company. Failure to provide the
proper amount of combustion air can result in a fire
or explosion and can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTYDAMAGE.
This water heater must not be installed directly on
carpeting. Carpeting must be protected by a metal
or wood panel beneath the appliance extending
beyond the full width and depth of the appliance by
at least 3 inches (76.2mm) in any direction, or if the
appliance is installed in an alcove or closet, the
entire floor must be covered by the panel. Failure to
heed this warning may result in a fire hazard.
AWARNING
VENT DAMPERS - Any vent damper, whether it is
operated thermally or otherwise must be removed if
its use inhibits proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80%
may produce a relatively low flue gas temperature.
Such temperatures may not be high enough to properly open thermally operated vent dampers. This
would cause spillage of flue gases and may cause
carbon monoxide poisoning.
Vent dampers must bear evidence of certification as
complying with the latest edition of American
National Standard ANSI Z21.68 (ANSI Z21.66 & 67,
respectively, cover electrically and mechanically actuated vent dampers). Before installation of any vent
damper, consult your local gas utility for further
information.
AWARNING
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.
AWARNING
* The appliance and its individual shutoff valve must
be disconnected from the gas supply piping system
during any pressure testing of the gas system at
test pressures in excess ofl/2 pound per square
inch (3,5kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal or
less than 1/2 pound per square inch (3.SkPa).
AWARNING
Soot build-up indicates a problem that requires correction before further use. Turn "off" gas to water
heater and leave "off" until repairs are made,
because failure to correct the cause of the sooting
can result in a fire or explosion causing DEATH, SERIOUS BODILY INJURY, OR PROPERTYDAMAGE.
AWARNING
AWARNING
Chemical vapor corrosion of the flue and vent system may occur if air for combustion contains certain
chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants,
swimming pool chemicals, calcium and sodium chloride, waxes, bleach, and process chemicals are typJcal compounds which are potentially corrosive,
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (L.R) gas is heavier than air.
Should there be a leak in the system, the gas will settie near the ground. Basements, crawl spaces, skirted
areas under manufactured (mobile) homes (even
when ventilated), closets and areas below ground
level will serve as pockets for the accumulation of this
gas. Before attempting to light or relight the water
eater's pilot or turning on a nearby electrical light
switch, be absolutely sure there is no accumulated
ground level in the vicinit_ of the appliance. If odor is
detected,

Safety Instructions continued on page 4.
Safety Instructions
_,WARNING
The water heater with draft hood installed must be
properly vented to a chimney which terminates outdoors. Never operate the water heater unless it is
vented to the outdoors and has adequate air supply
to avoid risks of improper operation, explosion or
asphyxiation.
AWARNING
Minimum clearances between the water heater and
combustible and noncombustible construction are 1'p
at the sides and rear, 4" at the front, and 6" from the
vent pipe. Clearance from the top of the jacket is 18"
on most models. Note that a lesser dimension may be
allowed on some models. Refer to the label on the
water heater adjacent to the gas control valve for all
clearances.
AWARNING
Flood damage to a water heater may not be readily
visible or immediately detectible. However, over a
period of time a flooded water heater will create
dangerous conditions which can cause DEATH, SERIOUS BODILY INJURY OR PROPERTY DAMAGE.
Contact the Maytag dealer from whom the appliance was purchased or call Maytag Customer Service
at 1-800-788-8899
for an authorized servicer to
replace a flooded water heater, Do not attempt to
repair the unit! It must be replaced!
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in
a hot water system that has not been used for a
long period of time (generally two weeks or more).
Hydrogen gas is extremely flammable and explosive.
To prevent the possibility of injury under these conditions, we recommend the hot water faucet be
opened for several minutes at the kitchen sink
before any electrical appliances which are connected
to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is
present, there will probably be an unusual sound
similar to air escaping through the pipe as the hot
water faucet is opened. There must be no smoking
or open flame near the faucet at the time it is open.
_WARNING
INSULATING JACKETS; When installing an external
water heater insulation jacket on a gas water heater:
• DO NOT cover the temperature-pressure relief valve.
• DO NOT put insulation over any part of the top of
the gas water heater.
• DO NOT put insulation over the gas control valve or
gas control valve/burner cover, or any access areas
to the burner.
• DO NOT let insulation around the gas water heater
to get within 8 inches of the floor (air must get to
the burner).
• DO NOT cover or remove operating instructions,
and safety related warning labels and materials
affixed to the water heater.
Failure to heed this will result in the possibility of a
fire or explosion.
ACAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplished in such a
manner that if the tank or any connections should
leak, the flow of water will not cause damage to
the structure. For this reason, it is not advisable to
install the water heater in an attic or upper floor.
When such locations cannot be avoided, a suitable
drain pan should be installed under the water
heater. Drain pans are available at your local hardware store. Such a drain pan must be not greater
than 1½ inches deep, have a minimum length and
width of at least 2 inches greater than the water
heater dimensions and must be piped to an adequate drain. The pan must not restrict combustion
air flow. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.

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 settingthat
satisfies your hot water

for the most economical use of the appliance. This water
heater is not for use in manufactured (mobile) homes or outdoorinstaUation,
heed this warning may result in a fire hazard.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
AWARNING
[

are
1" at the sides and rear, 4" at the front, and 6 from
the vent pipe. Clearance from the top of the jacket [
is 18" on most models. Note that a lesser dimension
may be allowed on some models. Refer to the label
The location selected should be indoors as close as practical to
the gas vent or chimney to which the water heater vent is going
to be connected, and as centralized with the water piping system
as possible. The water heater, as all water heaters, will eventually
leak. Do not install without adequate drainage provisions where

&CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplished in such a
manner that if the tank or any connections should
leak, the flow of water will not cause damage to
the structure. For this reason, it is not advisable to
install the water heater in an attic or upper floor.
When such locations cannot be avoided, a suitable
drain pan should be installed under the water
heater, Drain pans are available at your local hardware store. Such a drain pan must be not greater
than 1'/2 inches deep, have a minimum length and
width of at least 2 inches greater than the water
heater dimensions and must be piped to an adequate drain. The pan must not restrict combustion
air flow. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.
