F. Joint assembly
Working quickly, insert the pipe into the fitting socket bottom
and give the pipe or fitting a 1/4" turn to evenly distribute the
cement. Do not continue to rotate the pipe after it has hit the
bottom of the fitting socket. A good joint will have sufficient
cement to make a bead all the way around the outside of the
fitting hub. The fitting will have a tendency to slide back while
the cement is still wet so hold the joint together for about 15
seconds.
STEP G
G. Cleanup and joint movement
Remove all excess cement from around the pipe and fitting
with a dry cotton rag. This must be done while the cement is
still soft.
The joint should not be disturbed immediately after the
cementing procedure, and sufficient time should be allowed
for proper curing of the joint. Exact drying time is difficult to
predict because it depends on variables such as temperature,
humidity and cement integrity. For more specific information,
you should contact your solvent cement manufacturer.
T & P VALVE and PIPE INSULATION (On Selected Models)
Remove insulation for T & P
Valve and pipe connections
from carton.
Fit pipe insulation over the in-
coming cold water line and the
hot water line. Make sure that
the insulation is against the
top cover of the heater.
Fit T & P valve insulation over
valve. Make sure that the
insulation does not interfere
with the lever of the T & P
valve.
Secure all insulation using tape.
OPERATION
WARNING
NEVER OPERATE THE HEATER WITHOUT FIRST BEING
CERTAIN IT IS FILLED WITH WATER AND A TEMPERATURE
AND PRESSURE RELIEF VALVE IS INSTALLED IN THE RELIEF
VALVE OPENING OF THE HEATER. DO NOT ATTEMPT TO
OPERATE HEATER WITH COLD WATER INLET VALVE
CLOSED.
TO OPERATE THE WATER HEATER
FILLING
1. Close the heater drain valve by turning handle clockwise .
Fig. 1 (T)
2. Open a nearby hot water faucet to permit the air in the system
to escape.
3. Fully open the cold water inlet pipe valve (allowing the heater
and piping to be filled. Fig. 1(M)
4. Close the hot water faucet as water starts to flow from the
faucet.
5. The heater is ready to be operated.
TEMPERATURE REGULATION
WARNING
THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE
THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT
WATER TEMPERATURES REQUIRED FOR AUTOMATIC
DISHWASHER AND LAUNDRY USE CAN CAUSE PAINFUL
SCALDING WITH POSSIBLE SERIOUS AND PERMANENT
INJURY. THE TEMPERATURE AT WHICH INJURY OCCURS
VARIES WITH THE PERSON'S AGE AND THE TIME OF
EXPOSURE. THE SLOWER RESPONSE TIME OF CHILDREN,
AGED OR DISABLED PERSONS INCREASES THE HAZARDS
TO THEM. NEVER ALLOW SMALL CHILDREN TO USE A HOT
WATER TAP OR TO DRAW THEIR OWN BATH WATER. NEVER
LEAVE A CHILD OR DISABLED PERSON UNATTENDED IN A
BATHTUB OR SHOWER.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA
WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS.
IF A SUITABLE AREA IS NOT AVAILABLE, A COVER SHOULD
BE INSTALLED OVER THE THERMOSTAT TO PREVENT
TAMPERING.
Suitable covers are available through A.O. Smith
Water Products Company, 5621 W. 115th Street, Alsip, IL 60803.
It is recommended that lower water temperatures be used to avoid
the risk of scalding. It is further recommended, in all cases, that
the water temperature dial be set for the lowest temperature which
satisfies your hot water needs. This will also provide the most
energy efficient operation of the water heater. The water
temperature adjusting dial was factory set at the lowest
temperature; Turning the dial counterclockwise
decreases
temperature, and clockwise
increases temperature.
SETTING THE WATER HEATER TEMPERATURE AT 120°F
(APPROX. "HOT" MARK ON TEMPERATURE SETTING DIAL
OF GAS VALVE) WILL REDUCE THE RISK OF SCALDS
. Some
states require settings at specific lower temperatures.
Figure 9 shows the approximate water temperatures produced at
various thermostat dial settings. Short repeated heating cycles
caused by small hot water uses can cause temperatures at the
point of use to exceed the thermostat setting by up to 30°F. If you
experience this type of use you should consider using lower
temperature settings to reduce scald hazards.
