    Filter/drier in a hot gas line? Muffler in a liquid line? I've never seen either of those... There shouldn't be any confusion if you know which line you're looking at right?

    Why the condensate trap on the positive side of the fan? Is that code where you are? Also, is that the furnace power plugged into the wall outlet?
