Locating The Water Heater continued-
DO NOT locate the water heater where water lines could be subjected
to freezing temperatures. Locate the water heater so that access
panels and drain valves are accessible. Some models are not equipped
with a drain valve. For those models, install a drain tee in the cold water inlet
as close as practical to the water heater.
Water heater corrosion and component failure can be caused by the heating
and breakdown of airborne chemical vapors. Examples of some typical
compounds that are potentially corrosive are: spray can propellants, cleaning
solvents, refrigerator and air conditioning refrigerants, swimming pool
chemicals, calcium or sodium chloride, waxes and process chemicals.
These materials are corrosive at very low concentration levels with little or no
odor to reveal their presence.
NOTE: DAMAGE TO THE WATER HEATER CAUSED BY EXPOSURE TO
CORROSIVE VAPORS IS NOT COVERED BY THE WARRANTY. DO
NOT OPERATE THE WATER HEATER IF EXPOSURE HAS OR WILL
OCCUR. DO NOT STORE ANY POTENTIALLY CORROSIVE
COMPOUNDS IN THE VICINITY OF THE WATER HEATER.
This water heater must be located in an area where leakage of the tank or
water line connections and the combination temperature and pressure relief
valve will not result in damage to the area adjacent to the water heater or to
lower floors of the structure. When such locations cannot be avoided, a
suitable drain pan must be installed under the water heater. The drain pan
must have a minimum length and width of at least 4 in. (10.2 cm) greater
than the diameter of the water heater. The drain pan, as described above,
can be purchased from your plumbing professional. The drain pan must be
piped to an adequate drain. The piping must be pitched for proper drainage.
To comply with NSF requirements this water heater is to be:
a) Sealed to the floor with sealant, in a smooth and easily cleanable
way, or
b) Installed with an optional leg kit that includes legs and/or extensions
that provide a minimum clearance of 6” beneath the water heater.
Note: For California installation this water heater must be braced,
anchored, or strapped to avoid falling or moving during an
earthquake. See instructions for correct installation procedures.
Instructions may be obtained from California Office of the State
Architect, 400 P Street, Sacramento, CA 95814.
