ELECTRONIC PILOT & MAIN BURNER IGNITION SEQUENCE
FIRST STAGE - TRIAL FOR PILOT IGNITION
On every call for heat (system start), the S86 performs an internal safe-start check shows that a flame-simulating
condition is present. During a normal start, the S86 opens the pilot valve in the gas control. This allows gas to flow to
the pilot burner. Simultaneously, the electronic spark generator in the S86 produces a 15,000 volt spark pulse output.
This voltage produces a spark at the pilot burner ignitor/sensor rod, igniting the gas flowing around the electrode. If
the pilot flame is not detected during the trial for pilot ignition, the S86H contains a safety lockout timer (90 Seconds) to
limit the trial for pilot ignition period.
SECOND STAGE - MAIN BURNER OPERATION
When the pilot flame is established, a flame rectification circuit is completed to the burner ground. The S86 flame
sensing circuit detects the flame current and shuts the spark generator off. At the same time, the second operator
(main gas valve) is opened in the gas control, allowing gas flow to the main burners. The pilot flame ignites the main
burner conventionally.
