Furnace BTU size

[Stephen W. Stanczyk]

There was a large crate of machine parts in front of the furnace access. I was able to get the Model Number and Serial number with my extension mirror but could not get the angle right to get the BTU's. Searched the internet but can't find a listing of the BTU's.

York Diamond 80 High Effeciency Gas Fired Furnace converted to Propane.
Model = P3DND20N10401D
Serial = EEHM611744

Appreciate the help.

In addition to Preston's Guide, I've found the Technical Reference Guide just as valuable, or more so. Read about it at About Homes.
