LIGHTING THE GCO4S AND GCO4D/GCO6D OVENS

Turn manual Gas Valve ON.  Turn Master  Switch ON and turn Thermostat to its maximum setting.  Both the ON
and HEAT lights should come on.  If  HEAT light is not on, make sure door is closed.

After 5 seconds, the spark ignition system  will start and the solenoid valve will open, allowing gas to flow to the
burner for 7 seconds.  This 5-second purge and 7-second ignition trial will repeat up to two more times if the
burner does not light within the first 7-second ignition trial.  During this 5-second prepurge, the red NO IGNITION
light will be lit.

When the burner gas ignites, a slight "roar" will be heard.  This "roar" is a normal condition of the power burner
and will become almost undetectable in the normal operating mode after warm-up.  The NO IGNITION light will
go off when ignition occurs.

If the burner fails to light, the red NO IGNITION light will be lit and remain on.  Turn Master Switch OFF.  Turn
manual Gas Valve OFF.  Wait for five minutes before repeating lighting sequence previously described.

If the burner does not light after three trials, turn off the manual Gas Valve and call a qualified servicer.
