hydro level CG450 ???

Looking for opinions on this control, I really don't like the fact that it drops the burner out every 10 minutes for 90 secs.for an intermittent water level check, do you think it affects the steam making process? I've installed a couple of Peerless boilers with these on them for a fuel oil co. and today the owner calls and tells me he's going to back charge me for having to send his service guy out to adjust the pressuretrol, I had it set at 2 with a 1 diff., his guy bumps it up to 5 what gives??? Do ya think maybe the air vents need looking at? Plugged returns? What? This is a 4 section steam boiler in an older 2 story house. Any comments are appreciated. Thank you for your knowledge,
Frankie
