Firebird Popular 150

My first time working on one of these. Does this baffle information mean that those baffles should be removed for the 120 firing range?

The book says to remove the second row of baffles when the output is at lower half of range.Maybe the reason for this is the burner combustion head is different at the lower end.
if it were me,id be setting up the burner with the 4 baffles and see what flue gas reading i get,plus looking for a smooth burner start up

Thanks. The PDF that I have doesn't give that information. It does however show a head change at the 120,000 firing rate. And strangely, the same airbox at 150 and 120, but different on the firing rates in between. Also nozzle angle changes on anything below 150.

Not an original setup

I serviced the same boiler a few months back.The owner had bought the house a year previously but had intermittent lockouts on the burner.Burner was rdb2.2 t3 head.i serviced boiler but noticed the flame took a couple of seconds to establish.i change the combustion head to ld3 and burner started perfect.No lockouts since.
Looking at the S range firebird with a rdb2.2 burner ,the combustion head below 120kbtu is LD3,over 120kbtu combustion head T5.For output 125kbtu= 1.00 80s nozzle at 9bar with no mention of removing 2 baffles

Look at your FGA temp when flow is up near temp, will be a good indication of removal or not
