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 province 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
V alve, 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. 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
“T emperature Regulation” section in this manual, see Figure 26.

INSTALLATION INSTRUCTIONS
Removing the Old Water Heater
4. Att ach 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. 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. T o
avoid being scalded, make sure all
connections are tight and that the water
flow is directed away from any person,
see Figures 3 and 6.
5. Disconnect the vent pipe from the blower assembly where it connects
to the water heater. In most inst allations the vent pipe can be lifted off
after any screw or other attached devices are removed. Make sure
existing vent complies with maximum and minimum vent lengths on
page 18.
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, see Figure 7. This will
avoid cutting off pipes too short. Additional cuts can be made later if
necessary. Disconnect the temperature-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.
FIGURE 6.
FIGURE 3.
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 3 and 4.
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 3 and 5.
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 4.
FIGURE 5.
FIGURE 7.
If you have galvanized pipes 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, see Figure 8.
These pieces should be saved since they may be needed when
reconnecting the new water heater. 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. 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.

FIGURE 8.
FACTS TO CONSIDER ABOUT THE LOCA TION
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:
1. Select a location indoors as close as practical to the vent terminal or
location to which the water heater vent piping is going to be connected,
and as centralized with the water piping system as possible.
2. 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" (5.1 cm) greater than
the water heater dimensions and must be piped to an adequate drain.
The pan must not restrict combustion air flow.
INSTALLA TIONS 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 hot surface igniter or main burner. The resulting flashback
and fire can cause death or serious burns to anyone in the area. This
water heater is equipped with a FV sensor for detecting the presence
of flammable vapors, see Figure 9. When the sensor detects those
vapors, the unit will shut down and not operate. Should this happen,
please refer to the troubleshooting guide on pages 33-34. 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.
FIGURE 9.
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.
• Devices that will turn off the gas supply to a gas water heater while at
the same time shutting off its water supply .
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" (7.6 cm) 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.
Minimum clearances between the water heater and combustible
construction are 0 inch at the sides and rear, 5" (12.7 cm) from the front
