Natural gas conversion, Riello or Carlin EZ
I know this question has been asked before and opinions seem to be both manufacturers make burners that are very good for nat gas conversion. All contractors that bid on this job recommend either carlin or riello. The two bids/contractors I like best are very close in price with difference of burner only. I am leaning towards riello since they seem to be more expensive/ better quality but if ez is just as good for less $, that is good too. Any idea if one burner is quieter or superior to the other? These will be on running on a 205k btu steam boiler.
