Comfortmaker model number breakdown

[Tom Cissell]

Does anyone known how to break down a Comfortmaker furnace model number? I would like to know the BTUs. Model number is N9MSB1002116C1. Thanks in advance.

I think it is a 90 something % efficient at 100,000 BTU.
First number "9" is efficiency models. them
First numbers after 3 letter sequence is BTU.

Call a dealer and they can tell you the exact rating.
