ES AND SS NOZZLES FOR RIELLO?

anthony_7

Have a riello F5. When it is serviced wondering what would be the correct nozzle to use (es , ss or ???). Currently running 1.10 GPH and 60 degrees. Burner is connected to a Peerless wbv-04.
Is there a major difference on using the ES or SS? If neither of these are correct what should be used in servicing.

Like Ed said,

But let me give this a different spin.

If the boiler is attached to a chimney, go up and listen to it with the person who spends the most time in the same room. My experience with Riello burners is that they do roar in a chimney flue. My parents home as an example...I have to go over to the boiler to make sure the burner is running. When I'm talking to Mom in the living room, with the flue running paralell with the fireplace, I can hear it.

I've played the nozzle game front to back, and I'm gonna say....it depends on the situation. I particularly like the 60°W as an all around "feel good" nozzle. Playing with my Moms boiler, I found that a Hago 60°SS nozzle was a bit quieter. (given the room in a firebox and the choice of chimney,power venter or D.V. unit I chose the chimney.)

The advice I will give is, that the total of the package is the determining factor.The factory recommendations are but the first step.Knowledge and "time in the field/numbers received from your testing instruments" will be the deciding factors.The more you work with them, the more your feelings direct you.

Sounds vauge, but I state the truth.This is a personal thing and will be more obvious the longer you work with it.(Jimmy,Alan,George,Dave, Joe, Mark,Ed or anyone affiliated with Riello, did I miss anything? Chris
