weil mclain pump pressure

The nozzle is a delavan 1.25x80 deg.B set at 100 PSI.The reason I am changing is the new one has a delay valve.The older unit had after run on shutdown, Also transformer seems weak. I wanted to upgrade to the new type ignitor and the new psc motor.Also the interrupted ignition. Just thought that they would run it at a higher pressure to achieve better atomization and run cleaner.

W-M setup

Hello
I have a 12 year old Weil-MClain Gold Series Wgo4.I just bought a new Beckett B2007 AFG to update it. I was wondering if the pump pressure needs to be changed from 100psi to 140psi or so with a smaller nozzle.Would like to set it to the latest specs.

thanks

Why did you change the burner?

And at what pressure and firing rate (stamped on the nozzle) was the old one?

As long as you do not (combined nozzle firing rate + the added output at something above 100 p.s.i.) exceed the boiler plate BTU rated input - you are fine!

Of course, this assumes the burner head is designed to be in the firing rate you ordered/installed on the new Beckett. If it's not within range, problem # 1 becomes: Change the end cone to match the firing rate you need/want. Unless your home is very large, the boiler might be well served by downfiring the new burner.

too bad,...

You could have had a Riello....

you need to do the math on that. wisdom would say follow proper setup for the burner and boiler flue configurations while taking into account what is what around you while you are setting the burner up to function....

best leave it in the hands of someone who understands what to look for when ...

if you would like some more info just for personal understanding on the minor technicalities, Google Oil Tech Talks......look about on the site a bit..

FireDragons site has some of the instruments on sale to check these details....

Big question....

Does the new burner have the SAME fixed head as the old AFG?

If it has an L or V head...it's a whole different animal, all together.(IN UNISON EVERYONE!) It needs to be set up to BECKETT instructions, and fine tuned with the HELP of the W/M manual.

The nozzle selection is far different for both head types...as is the tuning and head measurements.

BTW, Good for you! The PSC motor and pre and post purge control is a smart idea, and you will save a bit on electricity...as well as having a longer ignitor life. It also seems to have helped stop the dreaded "cold soak" that used to happen to the AFG's in that boiler.
