Ignition State - ProFire PF3100 Product Manual

13.8 IGNITION STATE

The controller transitions to the Ignition state to initiate pilot light off for all connected pilot cards. The Ignition state
is a fuel state that energizes the pilot valve outputs and ignition outputs but holds all main valve outputs de-
energized. Successful pilot ignition is required for the controller to transition into any other fuel state.
