I have a Riello Mectron 5M on my New Yorker boiler. I have been unable to find a service/installation manual online, does anyone have one?
This year I changed from 1.0 USGAL nozzle to a 0.85 USGAL, I have looked at the manual for the Riello F5 and wonder if it is close enough to the 5M design that I can use it as a guide to rough in the initial air and turbulator settings for the new nozzle as detailed in the boiler manual.
I have a combustion analyzer and will make the final adjustments using it. What Stack temp, CO2 and excess air numbers should I aim for?
