FOREWORD
Thank you for buying this energy efficient water heater from
State. We appreciate your confidence in our products. Detailed
installation diagrams are in this manual. These diagrams will
serve to provide the installer with a reference for the materials
and method of piping suggested. IT IS NECESSARY THAT ALL
WATER PIPING AND THE ELECTRICAL WIRING BE INSTALLED
AND CONNECTED AS SHOWN IN THE DIAGRAMS.
In addition to these instructions, the water heater must be
installed in accordance with local codes and the authority having
jurisdiction.
GENERAL SAFETY INSTRUCTIONS
BE SURE TO TURN OFF POWER WHEN WORKING ON OR
NEAR THE ELECTRICAL SYSTEM OF THE HEATER. NEVER
TOUCH ELECTRICAL COMPONENTS WITH WET HANDS OR
WHEN STANDING IN WATER. WHEN REPLACING FUSES
ALWAYS USE THE CORRECT SIZE FOR THE CIRCUIT.
The principal components of the heater are identified on page 6.
The model and rating plate on page 5 interprets certain markings
into useful information. Both of these references should be
used to identify the heater, its components and optional
equipment.
WARNING
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 AND PROCEDURES.
INSTRUCTIONS MAY BE OBTAINED FROM YOUR LOCAL
DEALER, WHOLESALER, PUBLIC UTILITIES OR CALIFORNIA’S
OFFICE OF STATE ARCHITECT, 400 P STREET, SACRAMENTO,
CALIFORNIA 95814.
INSULATION BLANKETS
Insulation blankets available to the general public for external
use on electric water heaters are not approved for use on your
State water heater. The purpose of an insulation blanket is to
reduce the standby heat loss encountered with storage tank
water heaters. Your State water heater meets or exceeds the
National Appliance Energy Act standards with respect to
insulation and standby loss requirements, making an insulation
blanket unnecessary.
WARNING
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions (See page 5 for identification
of components mentioned below). Failure to follow these
instructions can result in fire, serious personal injury or death.
•
Do not cover the temperature & pressure relief valve.
•
Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
•
Do obtain new labels from State Water Heaters for placement
on the blanket directly over the existing labels.
EXTENDED NON-USE PERIODS
CAUTION
HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER
SYSTEM SERVED BY THIS HEATER THAT HAS NOT BEEN USED
FOR A LONG PERIOD OF TIME (GENERALLY TWO WEEKS OR
MORE). HYDROGEN GAS IS EXTREMELY FLAMMABLE.
To
reduce the risk of injury under these conditions, it is recommended
that the hot water faucet be opened for several minutes at a nearby
kitchen sink before using any electrical appliance connected to
the hot water system. If hydrogen is present, there will probably
be an unusual sound such as air escaping through the pipe as
the water begins to flow.
THERE SHOULD BE NO SMOKING OR
OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPENED.
CAUTION
AN ELECTRICAL GROUND IS REQUIRED TO REDUCE RISK
OF ELECTRIC SHOCK OR POSSIBLE ELECTROCUTION. THE
GROUND SCREW AT THE JUNCTION BOX IS FOR BONDING
THE HEATER TO A GROUNDED SERVICE ENTRANCE
CONDUCTOR, A GROUNDED SERVICE ENTRANCE RACEWAY,
OR AN EARTH GROUNDING ELECTRODE CONDUCTOR.
WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING AND
ELECTRICAL WORK ARE REQUIRED.
GENERAL
The installation must conform to these instructions, the local
code authority having jurisdiction, and the requirements of the
power company. In the absence of code requirements follow
the current edition of NFPA-70, The National Electrical Code
which may be ordered from: National Fire Protection Association,
1 Batterymarch Park, Quincy, MA 02269.
LOCATION
The water heater should be located as close as possible to/or
centralized to the water piping system. The water heater should
be located in an area not subject to freezing temperatures.
The heater should be located in an area where leakage of the
tank or connections will not result in damage to the area adjacent
to the heater or to lower floors of the structure.
When such locations cannot be avoided, a suitable drain pan
should be installed under the heater.
Such pans should be at least two inches deep, have a minimum
length and width of at least two inches greater than the diameter
of the heater and should be piped to an adequate drain.
Drain pans suitable for these heaters are available from your
distributor or A.O. Smith Water Heater Parts Fulfillment, 125
Southeast Parkway, Franklin, TN 37068.
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.
