GENERAL SAFETY INFORMATION
CAUTION
TEXT PRINTED OR OUTLINED IN RED CONTAINS INFORMATION
RELATIVE TO YOUR SAFETY. PLEASE READ THOROUGHLY
BEFORE INSTALLING AND USING THIS APPLIANCE.
EXTERNAL DAMAGE
Do not operate the water heater until it has been fully checked out
by a qualified service technician, if the water heater:
•
Has been exposed to fire or damage.
•
Produces steam or unusually hot water.
If the water heater has been subject to flooding, it must be replaced.
INSULATION BLANKETS
Insulation blankets available to the general public for external use on electric
water heaters are not approved for use on your A. O. Smith water heater.
The purpose of an insulation blanket is to reduce the standby heat loss
encountered with storage tank water heaters. Your A. O. Smith water
heater meets or exceeds the National Appliance Energy Conservation 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 Figure 1 for identification of components
mentioned below). Failure to follow these instructions can result in fire,
asphyxiation, serious personal injury or death.
•
Do not cover the temperature & pressure relief (T&P) valve.
•
Do not cover the instruction manual. Keep it on the side of the water
heater or nearby for future reference.
•
Do obtain new warning and instruction labels from A.O. Smith for
placement on the blanket directly over the existing labels.
EXTENDED NON-USE PERIODS
WARNING
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 the 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 OPEN.
