I have a variable speed blower + 41K BTU output on 1st stage furnace.
The blower is set to 1000 CFM for 1st stage. Altitude about 100ft.
1000 cfm x 43.3F temperature rise * 1.08 = 46,764 BTU
That's roughly 14% higher than the plate rating. Is that within the margin of error given the accuracy of the inputs? Or could something need adjustment?
