    I don't like drains run in front of furnaces from a service standpoint, but that setup will drain just fine.

    That is a very restrictive return air drop and filter connection. I would want that redone if it was mine.

    I always take fresh air from the outside

    You are using old filters in a new unit? Please get new ones
    Unless the house is hermetically sealed at every joint, I don't think a 50cfm ID fan will be able to create that much suction. I don't see many houses being that ultra tight... especially if they have operable windows.

    But yes, it will make the home slightly negative.

    The installation company said they could do it for me, but gave me this warning -

    Furnaces with fresh air intake from outside sometimes get junk (leaves and yard wastes) sucked from the outside and this problem is not covered by the warranty...

    It seldom happens, however, I put a "extended" hardware cloth screen on my intake because the exhaust and intake go out where my wall ivy is. I've never had a prob.

    Really? So combustion principles for furnaces are different than automotive? Maybe I remember a post on this in the Pro section.
    I would say cleaner, in my comparisons, with outside air. No chemicals, household dust, lint debris to be sucked in as combustion air and burned onto the flame sensor.

    That's true but not an issue if you dont let leaves build up. The intake and exhaust should be at least 12" above the ground,or above normal snow levels.

    I think cleaner burning might be in reference to either the fuel air ratio changing due to colder denser air. IT also might be expressing how much longer the HE will take to warm up if cold outside air is able to cool it off. I could see this causing some sooting as well as possibly causing some initial condensation in the primary heat exchanger.

    the drain gentleman will possibly spew water out where the humidifier is tied in due to the fact that it is tee-d in at the same height as the coil without a trap, Air pushes past the water at the humidifier.. The humidifier drain shoud be tied in at the floor. Trust me . Ive come back to fix this from my installers a bunch of times. Water all over the floor.

    tell the appliance delivery people, installers, thats a chance youre willing to take for fresh outside air for combustion
