SYSTEM OPERATION
Automatic ignition controller for po-
wer burners (see fig. 3 and 4)
When thermostat calls for heat, fan is
energized if air proven switch is in the
no air position.
When sufficient air flow is proven by the
air proving switch, a prepurge period
(T
p
) elapses before the optional built--in
spark igniter or the external ignition
transformer and the pilot gas valve (V
1
)
is energized in case of intermittent pilot
ignition or both gas valves (V
1
and V
2
)
are energized in case of direct burner
ignition.
The ignition spark ignites the gas and
the resulting flame is detected by the
flame rod.
Ignition is switched off immediately
after flame is established.
If flame is not established within the
safety time (T
s
), the automatic ignition
controller locks out.
If air flow is not proven by the air
proving switch, the automatic ignition
controller will lockout after T
p +
T
s
.
If flame is lost during normal run, the
automatic ignition controller repeats the
start sequence.
Lockout reset
The auto ignition controller will be reset
by depressing the reset button.
Press the button completely down.
If a first reset is not succesful wait at
least 15 seconds before making
another attempt.
