Locating the Water Heater continued-
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.
1. Minimum clearance to combustible material is 0 inches for the Top,
Sides, Front, and Rear of this water heater. However, it is
recommended that at least 18 inches (45.7 cm) from the Top, and
24 inches (61 cm) from the Front. Clearance for servicing may be
reduced down to minimum clearance to combustible material, but
service time and effort may be greatly increased.
2. Increase distances to provide clearances for servicing.
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.
