INSTRUCTIONS FOR INSTALLATION
Removing the Old Water Heater
FIGURE 1.
1. Turn “OFF” the gas supply to the
water heater.
If the main gas line Shut-off valve
serving all gas appliances is
used, also shut “OFF” the gas at
each appliance. Leave all gas
appliances shut “OFF” until the
water heater installation is
completed, see Figures 1 and 2.
2. Turn “OFF” the water supply to the
water heater at the water shut off
valve or water meter. Some
installations require that the water
be turned off to the entire house,
see Figures 1 and 3.
3. Check again to make sure the gas supply is “OFF” to the
water heater. Then disconnect the gas supply connection
from the gas control valve.
FIGURE 2.
FIGURE 3.
4. Attach a hose to the water heater
drain valve and put the other end
in a floor drain or outdoors. Open
the water heater drain valve
(behind outer door). Open a nearby
hot water faucet which will relieve
pressure in the water heater and
speed draining. The water passing
out of the drain valve may be
extremely hot. To avoid being
scalded, make sure all
connections are tight and that the
water flow is directed away from
any person, see Figures 1 and 4.
5. Disconnect the vent pipe from the draft hood where they
connect to the water heater. In most installations the vent
pipe can be lifted off after any screw or other attached devices
are removed. Dispose of the draft hood. The new water
heater has the draft hood which must be used for proper
operation.
6. If you have copper piping to the water heater, the two copper
water pipes can be cut with a hacksaw approximately four
inches away from where they connect to the water heater.
This will avoid cutting off pipes too short. Additional cuts can
be made later if necessary. Disconnect the temperaturepressure relief valve drain line. When the water heater is
drained, disconnect the hose from the drain valve. Close the
drain valve. The water heater is now completely disconnected
and ready to be removed, see Figure 5.
FIGURE 5.
If you have galvanized pipe to the water heater, loosen the
two galvanized pipes with a pipe wrench at the union in each
line. Also disconnect the piping remaining to the water heater .
These pieces should be saved since they may be needed
when reconnecting the new water heater. Disconnect the
temperate-pressure relief valve drain line. When the water
heater is drained, disconnect the hose from the drain valve.
Close the drain valve. The water heater is now completely
disconnected and ready to be removed. Mineral buildup or
sediment may have accumulated in the old water heater.
This causes the water heater to be much heavier than normal
and this residue, if spilled out, could cause staining, see
Figure 6.

TYPICAL INSTALLATION
MIXING V ALVE USAGE
FIGURE 8.
This appliance has been design certified as complying with
American National Standard/CSA Standard for water heaters
and is considered suitable for:
Water (Potable) Heating: All models are considered suitable
for water (potable) heating.
HOTTER WA TER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, 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, shall 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. See Figure 8. Valves for reducing point of use temperature
by mixing cold and hot water are also available. Consult Maytag
Customer Service (1-800-788-8899). Follow mixing valve
manufacturer’s instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual, see Figures
22 and 23 on page 20.

LOCATING THE NEW WATER HEATER
Facts to Consider About the Location
Carefully choose an indoor location for the new water heater,
because the placement is a very important consideration for
the safety of the occupants in the building and for the most
economical use of the appliance. This water heater is not for
use in manufactured (mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater
in a new location, the following critical points must be observed:
• Select a location 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.
• Selected location must provide adequate clearances for
servicing and proper operation of the water heater.
Installation of the water heater must be accomplished in such a
manner that if the tank or any connections should leak, the flow
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
have a minimum length and width of at least 2 inches (51 mm)
greater that the water heater dimensions and must be piped to
an adequate drain. The pan must not restrict combustion air
flow.
• Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.
INST ALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED
(GARAGES, STORAGE AND UTILITY AREAS, ETC.):
Flammable liquids (such as gasoline, solvents, propane [LP or
butane, etc.] and other substances such as adhesives, etc.)
emit flammable vapors which can be ignited by a gas water
heater’s pilot light or main burner. The resulting flashback and
fire can cause death or serious burns to anyone in the area.
Even though this water heater is a flammable vapors ignition
resistant water heater and is designed to reduce the chances
of flammable vapors being ignited, gasoline and other
flammable substances should never be stored or used in the
same vicinity or area containing a gas water heater or other
open flame or spark producing appliance.
Also, the water heater must be located and/or protected so it is
not subject to physical damage by a moving vehicle.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage
may result in property damage, even with the use of a drain pan
piped to a drain. However, unanticipated damage can be reduced
or prevented by a leak detector or water shut-off device used in
conjunction with a piped drain pan. These devices are available
from some plumbing supply wholesalers and retailers, and
detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or
turn off the incoming water to the water heater when leakage
is detected.
• Sensors mounted in the drain pan that turn off the water
supply to the entire home when water is detected in the drain
pan.
• Water supply shut-off devices that activate based on the
water pressure differential between the cold water and hot
water pipes connected to the water heater.
This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath
the appliance extending beyond the full width and depth of the
appliance by at least 3 inches (76.2 mm) 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.
