8.  If the Flame Sensor does not detect a strong enough flame, the 

Ignition Control shuts off the Gas Valve and allows the blower to 

purge the unit for 30 seconds.  At that time, the Ignition Control 

restarts with step 6. It will try and ignite the main burners 2 more 

times.  If the unit does not light, the Ignition Control will wait 15 

minutes and then restart at step 6. This cycle will continue until 

the unit lights or the power is shutoff to the unit.

9.  If the Flame Sensor detects a strong flame, the Ignition Control 

will allow the unit to operate until the thermostat is satisfied.

10. Once the unit is satisfied, the Thermostat will shut off the blower, 

Gas Valve and Ignition Control and the unit will be in standby 

mode until another call for heat is initiated by the thermostat.

See the flow chart on page 27 for more detailed information.
