To set the combustion curve, the burner must be on. If all conditions to start the boiler have been met, the
<Burner Start> pushbutton will appear on the Combustion Setup screen. Press <Burner Start>; the purge
sequence will run and the actuators will return to the lightoff position. Press <Lightoff>. The Flame Safeguard
will sequence through pilot trial and main flame and the burner will ignite. The actuators can now be
positioned for the first point.
• 8 points minimum must be stored for a valid curve (16 maximum allowed)
• Points can not be skipped
• Values for Air and Fuel Actuator 1 must be greater than previous values for a valid point to be stored.
• Pressing <New Profile> at any time will erase the current curve.
• When the combustion curve is complete (8 valid points are stored) the <Firing Rate> button will appear,
replacing the <Main> button.
• Pressing <Pt Adv Enable> will allow stepping through the combustion curve using <Next> and <Prev>.
With Points Advance disabled, the actuators will not move when <Next> or <Prev> is pushed.
