is appropriate
WARNING! Do not store or use 
fl ammable materials, vapors, or 
liquids in the same loca on where this 
water heater is installed.
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 
and depth of the water heater 
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 oor shall be covered 
by the aforestated panel.
•   If your area is prone to earth-
quakes, use special straps as 
required by local building codes.
NOTICE: The state of California re-
quires bracing, anchoring, or strap-
ping the water heater to avoid its 
moving during an earthquake. Contact 
local u li es for code requirements in 
your area, visit h p://www.dsa.dgs.
ca.gov, or call 1-916-445-8100 and 
request instruc ons. Other loca ons 
may have similar requirements. Check

•   Avoid loca ons such as a cs, up-
per fl oors, or where a leak might 
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 
in accordance with this manual’s 
instruc ons. Install a metal drain 
pan under the water heater piped 
to an adequate drain. Inspect the 
drain pan, pipes, and surrounding
