IGNITION CONTROL MODULE
The ignition control module is energized when 24 volts is applied between terminals 5 & 6.
The module outputs 24 volts from terminals 2 & 3 to the pilot valve coil (PV) on the gas combination valve,
allowing gas flow to the pilot burner.
At the same time, the module generates a spark voltage output of approximately 13K at terminal 9 to begin
sparking at the ignitor/flame sense electrode.
The sparking will continue until an adequate pilot flame sense current is sensed by the module or for a maximum
of 90 seconds.
NOTE: If pilot is not established within the 90 second ignition trial time, the ignition module locks out by removing
power to the gas combination valve. The system remains locked out until the on/off switch is cycled to reset the
system and re-start the ignition trial cycle.
With the pilot burner lit, a flame sense current in DC micro amps is rectified thru the ignitor cable back to
terminal 9.
When the module senses a sufficient pilot flame current, the module outputs 24 volts from terminal 1 & 2 to
energize the main valve coil (MV) on the gas combination valve, allowing gas flow to the runner tube and main
burners.
When power to the ignition control module is removed, the output voltages are also removed. The pilot valve coil
(PV) and the main valve coil (MV) on the gas combination valve are de-energized and close. Gas flow to the pilot
burner, runner tube and main burners stop and all burners go out.
