Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

The filter size isn't in the specs for your model. It is ndcated that an external filter rack is recommended. Do you have a slot on the side (at the bottom)of the furnace where the return duct connects? It may have a narrow cover over it.
