Viessman oil to gas

ScottSecor

Have a good friend that is a plumber (does very little with heat). He has an excellent customer with a roughly eight year old Viessman oil fired boiler that was installed before he moved in. This is a very large house I gather. The local utility company is installing gas lines in the street and this guy wants to convert his boiler from oil to gas.

I am awaiting on the boiler model number, but I am certain the existing oil burner is a Riello 40 F10 rated to fire between 1.45 and 2.95gph. Plumber will run the gas line, do the air test etc. If time permits we will clean the boiler, install the new gas burner and the double acting damper with sensor, wire it in and finally dial it in.

Over the years, we have installed Beckett, Powerflame, Carlin, Industrial Combustion and Midco gas burners. I am not familiar with Riello as we basically went away from oil when they started to get popular. I am looking for a suggestion in a replacement gas power burner and any tips. Thank you,

We are awaiting the boiler model information. I suspect it is a Viteron rated at 245,000, will confirm shortly.

Carlin has setup specs for their EZ-Gas Pro for Vitoronds up to the VR1-245. This would be my choice. Go here and scroll almost all the way down:

Thank you Frank. I was fearful it was an odd sized burner tube. Makes things much easier.

I prefer Riello burners, but if the manufacturer has a direct replacement and specs for the Viessmann boiler, it's safe to use.

Just learned that boiler was built in 2000. Boiler is a Vitorond 200, model VR2-63. The current Carlin guides do not show this model boiler, I suspect because of the age?
