Before installing your water heater,
ensure that it will be located:
• Indoors in an area with adequate
air supply.
• In an area that will not freeze.
• As close as possible to a chimney
or vent.
• In a metal drain pan piped to an
adequate drain.
• In an area suitable for ver
cal
installa on.
• In an area with adequate space
(clearances) for periodic servicing
(there must be a minimum of 24
inches of front clearance).
• In an area that allows a minimum
clearance from combus ble sur-
faces as stated on the data plate.
• On a fl
oor that can support the
weight of a water heater full of
water.
You will also want to follow these
guidelines while considering an appro-
priate loca on:
• Do not install near air-moving
devices such as exhaust fans,
ven la on systems, or clothes
dryers.
• Do not obtain ven
la ng air for
the furnace/air handler from the
same space as the water heater.
Ensure that any return air ducts
near the water heater are sealed.
• If the water heater is located
in an area subject to lint, dust,
or oily vapors, at least annually
check and clean the air
fi lter. See
Maintenance sec on for steps on
cleaning the air
fi
lter.
• Do not install in a bathroom,
bedroom, or any occupied room
normally kept closed.
• If the water heater is installed di-
rectly on carpe ng, it shall be in-
stalled on a metal or wood panel
extending beyond the full width

by at least 3 in (76.2mm) in any
direc on. If the water heater is
installed in an alcove or closet,
the en re
fl

quakes, use special straps as
required by local building codes.
NOTICE:

In a garage, install a vehicle stop to
avoid water heater damage.
• Avoid loca
ons such as a cs, up-
per

damage the structure or furnish-
ings. Due to the normal corrosive
ac on of water, the tank will
eventually leak. To minimize prop-
erty damage from leaks, inspect
and maintain your water heater

instruc ons. Install a metal drain
pan under the water heater piped
to an adequate drain. Inspect the
drain pan, pipes, and surrounding
