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:
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 clearance of
at least 1.0” (2.5cm) greater than any point on the water heater’s
outer jacket and must be piped to an adequate drain. The pan must
not restrict combustion air flow. For example, if a circular pan is
used, it must be a minimum of 27” (69cm) in diameter. See Figure 1.
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 building 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.
INSTALLATIONS 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.
Also, the water heater must be located and/or protected so it is not
subject to physical damage by a moving vehicle.
locatInG the new 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” (7.6 cm) in any direction, or if the appliance is installed
