3.0 Operation
Lighting Instructions
1. Rotate the heater’s valve knob to the “ON”
position.
2. Close electrical circuit (typically the thermostat).
3. If the heater fails to light, turn off gas, open
electrical circuit and wait 5 minutes before
repeating the above steps.
Shutdown Instructions
1. Open electrical circuit.
2. Rotate the heater’s valve knob to the “OFF”
position.
Upon satisfactory completion of the electrical supply
and purging of the gas supply line to the heater(s),
follow the lighting instructions on the heater’s rating
label to put the heater into operation.
Sequence of Operation
Starting Circuit: Upon a call for heat, voltage is
applied to L1 and Neutral. After a pre-purge, the spark
electrode is energized and the gas valve opens. The
trial for ignition is 15 seconds. If flame is not sensed,
the heater will attempt two more times to reignite.
Running Circuit: After ignition, the sensing electrode
monitors the burner flame. If sense of flame is lost,
the control immediately acts to reignite the gas-air
mixture. If flame sense is not established within 15
seconds, the heater will attempt two additional ignition
sequences before proceding to hard lockout. The
control can be reset by briefly interrupting the power
source.
