Anyone know of a conversion formula to determine manifold gas pressure?
I ran into an old firetube boiler the other day that started it's life in 1962 as oil fired, converted to LP gas in the late 90's. Customer recently switched gas providers and now they can't get it to run right, so they called us. I found several problems with the fuel supply which is being addressed by the gas company before I return.
There is a burner manual onsite from the gas conversion but all numbers are for natural gas. So knowing the design manifold pressure @ design cfh of nat. gas can I covert that to LP gas, so that I will have an estimate manifold pressure at high fire, when I return to setup the burner?
Don't see many commercial LP gas burners around these parts!!
