Where is the filter on my Trane XL80?
Okay, please don't laugh. I've read the owner's manual and the Trane site a couple times now. It's totally gobbledygook to me. So here are my more than silly questions:
--The manual talks about upflow, upflow installed horizontally, and downflow. Can someone please give me a simple explanation so I can understand what I have and which part of the manual applies?
--Assuming I have an upflow furnace, I just can't find the two latches on the blower door where the filter supposedly it. (Sheesh--what's a blower door?) Can anyone help me find it?
I do have an electronic air cleaner that sits on top of the furnace. And someone told me that that's the only filter I have. Could that be true?
I would really appreciate any help. Thanks so much.
