Burdurs G115-4 w/ Carlin EZ1

ThatKidChris

Hi everyone I’ve been dealing with a G115-4 with a Carlin EZ1 and a SS2 powerventer for the last few weeks, before I cleaned it the customer was having troubles with it tripping off. Even after I cleaned it, it’s still tripping off. I’ve replaced the fuel pump, burner cupling and also fixed the draft control put it back to a .05. Every 4ish days it will trip off now and I’ve called Carlin they are stuck as well the rep keeps telling me to bump up the fuel pressure to prevent the flame coming off the head

What are your combustion #s??

I think we need a little more detail. What specifically did you do during the cleaning? Nozzle/filter/strainer? Combustion test? Brush heat exchanger?

Spark quality? Cad cell readings?

What is your nozzle/pump pressure combo now? What does buderus call for?

sounds like a cad cell or primary issue, or need to purge the oil line

Is the G215 approved by Buderus for power venting?
News to me, it being a positive pressure boiler.

A G 115WS/4 with a Carlin EZ-1 calls for a .75 x 60° B nozzle at 160 PSI oil pressure with the head set at 0.75 and the breech draft set to -0.03" w.c.
A G 115/28 with a Carlin EZ-1 calls for a Delavan .65 x 70° A or a Hago .65 x 60° ES at 150 PSI oil pressure with the head set at .60/.65 and the breech draft set to -0.03" w.c.

Both models are the same boiler, they ship with different firing rates to suit the customer's needs.
