I bought a generac xp8000e (8kw/12kw). I am converting it to tri fuel. It has a 410cc engine. I am trying to determine the btu or cubic feet of natural gas required to run this. This will allow me to determine the size of the pipe.
I am running a NG boiler on the inside of the wall where I want to place this but my heating guy feels if I tap off that line, it will starve the boiler. Any advice on how to calculate the btu or cubic ft of NG?

10k BTU / HP is a good rule of thumb. Check out the uscarb.com website for some very good information regarding pipe sizing.

You can easily convert cc to hp via google.

25cc per hp is also a pretty standard ratio to use for conversion so you are looking at 16 +\- hp and 160k BTU of demand.

Thank you that helps out . Hopefully I won't need to run a new line or I will have to cut out 40' of Sheetrock
