monitor parts interchangability

[rrob311]

I have a new burner pot for the m2200 heater. Will it work with a model 21 or 422?

I also have a new Combustion fan for a 2400. Will it work with a 441 or 41?

The burn pot or blower assy from the 2200 will not work on the 21 or 422
Acording to the service manual Parts list they have different part #s

Burn pot Part # for the 2200 is #6749
Burn pot Part # for the 422 is #6182

Blower assy Part # for the 422 is #6140
Comb Blower Assy for the 2200 is #6764

I have the service manuals for them both if you would like a copy. They include exploded views and key and part #'s
