1.2 BURNER SEQUENCING
When initiating a start sequence, the BMS will open the pilot and energize the igniter for the trial for
ignition period and wait for the flame sensor to confirm a flame. Upon flame verification, the unit will
then go into “Normal Operation”. At this point, the BMS will energize the main burner and the flame
status output(s). The temperature control option will also become enabled (if configured).
Set points and the associated password protected timers are configurable in the BMS menu. Other
configurable options:
• Purge and Pre-purge
• Auto Relight on Flame Fail
• Auto Relight on Power Fail (unit will relight when power is restored)
