Operation (T3)
After the ignition period, the operation period begins. It will last as
long as there is flame or until the heater is turned off.
During this period:
The fan runs.
The ignition transformer (TR) is OFF. There is no spark across the
electrodes.
The fuel solenoid (SV) is open and flame is self-sustaining. The
cad cell (PH) monitors the flame. If the flame is interrupted through
lack of fuel or lack of air, the machine will go through the prepurge
and ignition period in an attempt to re-establish the flame. If the
flame is not re-established, the aftercooling period begins.
Aftercooling (T5)
After the heater is turned OFF (or after flame re-establishment has
failed), the aftercooling period begins. It lasts approximately 1 minute
and 45 seconds.
During this period:
The power switch is OFF.
The fan runs. After approximately 1 minute and 45 seconds, the
fan stops.
The ignition transformer (TR) turns ON and remains ON. It pro-
duces a continuous spark across the electrodes so that any resid-
ual fuel is ignited and burned off.
Reset
To reset the heater:
1. Wait 30 seconds after the lockout condition has occurred.
2. Push the reset button.
