Wiring
Follow the wiring instructions furnished by the appliance manufacturer,
if available, or use the general instructions provided below. When these
instructions differ from the appliance manufacturer, follow the appliance
manufacturer instructions. Make sure wiring insulation does not get cut by
sharp edges.
NOTE:
All wiring must comply with applicable electrical codes
and ordinances.
Connect control circuit to the water heater control using the connections
shown in Fig. 5.
Fill Tank
Refer to the appliance manufacturer’s instructions to fill the tank with water.
Pilot Gas and Lighting Procedure
1. Start by turning the device knob to PILOT, push the knob down and hold in
position. (The pilot valve opens and allows gas to flow into the pilot burner.)
NOTE:
If the gas pipe is full of air (new installation), it takes a long time to
purge the air through the pilot before the pilot will light. Approximately
5 minutes of purge time is required for every 10 feet of 1/2 in. pipe
with 5 in. w.c. pressure.
2. Depress the piezo igniter to light the pilot flame and hold the knob in until
the status indicator starts to blink (approximately 30 seconds), indicating
pilot now being held by electronics.
NOTE:
LED should blink once every three seconds. If not, check the error
codes in Table 3.
3. Release the knob and turn to the desired temperature setting. The burner
will come on if water temperature is significantly below the temperature set
point and the LED should continue to blink once every three seconds.
Turn on Main Burner
Follow the instructions provided by the manufacturer or turn up the
temperature at the set point knob.
WARNING
Scalding Hazard.
Can cause burns, severe injury or death.
Never move the set point knob past the Hot setting unless extremely
hot water is desired. Always check water temperature at the faucet
and readjust until comfortably warm to the touch. Consider the ages
and health of all who will come in contact with heated water.
