I have a Cummins Onan generator model#20ES, 13kW, Spec#57292F,

Resolved Question:

I have a Cummins Onan generator model#20ES, 13kW, Spec#57292F, and is set up for LP gas. I need to know how many BTU's/cfh this unit consumes so that I can calculate the proper size gas line that I need to run to the unit. All I need to know is the maximum BTU rating of the unit.

Hello, my name is XXXXX XXXXX i would like to help you with your question

Superiormowers :

Your unit should consume something very close to 150 cfh, at full load

Superiormowers :

That equates to roughly 4 gallons of gasoline, which goes to 500000 btus per hour (125,000 btu per gallon of gas). Hope this helps you with setting up your generator!
