Figure 7.4.xiv Draft Control Alarms
16. The draft control alarms will appear in the Expansion Alarm log. Draft pressure sensor alarms
can be configured so that they either lockout the burner, or keep the burner running with the
draft servomotor position returned to its commissioned position along the firing curve. Any
servomotor errors will result in a burner shutdown which will not permit the burner to be
restarted until rectified.
