OPERATION
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.
FILLING
1. Close the heater drain valve by turning handle clockwise,
Figure 1.
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, see Figure 1.
4. Close the hot water faucet as water starts to flow.
5. The heater is ready to be operated.
TEMPERATURE REGULATION
DANGER
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 THE
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.
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 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 setting was factory set at the lowest temperature;
Pressing the "COOLER" button decreases temperature and
pressing the "HOTTER" button increases the temperature.
SETTING THE WATER HEATER TEMPERATURE AT 120°F (49°C)
(APPROX. “
” MARK ON TEMPERATURE SETTING OF GAS
VALVE) WILL REDUCE THE RISK OF SCALDS.
Some states
require settings at specific lower temperatures.
Figure 28 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
(-1°C). If you experience this type of use you should consider
using lower temperature settings to reduce scald hazards.
Valves for reducing the
point of use temperature by mixing cold
and hot water are available, see Figure 2. Also available are
inexpensive devices that attach to faucets to limit hot water
temperatures.
Contact a licensed plumber or the local plumbing
authority.
To avoid any unintentional changes in water temperature
settings, the control has a tamper resistant feature for changing
the temperature setting. To change the temperature setting follow
these instructions:
1. "Wake Up" the temperature indicators by holding down both
"COOLER" and "HOTTER" temperature adjustment buttons
at the same time for one second, see Figure 28. One or two
of the temperature indicators will light up. These indicators
will only remain on for 30 seconds if no further buttons are
pressed. After 30 seconds the control will go back to "Sleep"
mode.
2. Release both of the temperature adjustment buttons.
A. To decrease the temperature press and release the
"COOLER" button until the desired setting is reached.
B. To increase the temperature press and release the
"HOTTER" button until the desired setting is reached.
NOTE: Holding down the button will not continue to lower or
raise the temperature setting. The button must be pressed and
released for each temperature change desired.
SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL
TO SHUT OFF, TURN OFF THE MAIN MANUAL GAS SHUTOFF
VALVE TO THE APPLIANCE, SEE FIGURE 1(G).
