nozzle question

Can you replace a (B)nozzle with a (W)nozzle.

Nozzle

Under some circumstances possibly. Why do you want to do this??

I heard some techs like this nozzle better for cleaner light offs and better co readings.Just looking any opinions on this.

That really depends on

the burner spec. What unit are we taking about?

Going the other way I would stay with a W if it was 'spec', but several good alternatives to that are a Monarch or Delavan AR and an AB from Danfoss

Firedragon the boiler in question is a penscotti with a reillo burner.I installed this nozzle on a pm visit last June. The homeowner does have an indirect so it has lite off this summer.He was having lockout issues so another tech replaced wit a b nozzle.The homeowner has not had any more problems.Im not sure if just the nozzle was defective or if because it was a w.I have installed w nozzles in many other apllications with very good combustion readings.I do perform testo digital readingson all calls.Just looking for any helpful input.Thanks

In my Riello

Handbook I state that I prefer a Delavan W or the AB from Danfoss in a Riello/Pensotti combo. That's what has been keeping me warm for 24 years, FACT!

However, in the smaller firing rates the newer (since 2000) F-40's seem to have some great success with hollow types. It's a different head and spinner design.

I do have your handbook.Where in there is the info on the pesnscotti boiler with the w nozzle.The penscotti I was talking about had the reillo mectron(redbox) burner.Thanks for your help.
