Universal Ignition Control Uni-Kit
  • When The Thermostat Calls For Heat, The 780-845 Control Simultaneously Initiates Ignition Sparking and Opens The Pilot Valve Portion Of The Gas Valve. Pilot Flame Recognition Stops Ignition Sparking and Opens The Main Valve Portion Of The Gas Valve.
  • Pilot Burner Flame Is Continuously Monitored At A Synchronous Frequency For The Duration Of The Heating Cycle. Should The Pilot Flame Fail During The Heating Cycle, The Control Will Shut Off The Main Valve Until The Pilot Flame Is Established.
  • The 780-845 Lockout Ignition Control Provides 90 Seconds Of Spark, Followed By A 6 Minute Time Delay (Purge) Between Ignition Attempts. After Three Tries, If No Pilot Flame Is Sensed, The Control Goes Into A One-Hour Lockout Period. At The End Of The Lockout Period, If The Demand For Heat Is Still Present, The Unit Will Repeat The Three Tries For Ignition.
