    90% vent booster ?

    I am working on 90% furnace vented with 2 inch pvc up about 35 feet through two other condos. Thing is the inducer fan can't build enough pressure to activate the pressure switch. Running new pipe is close in impossible. I was wondering if adding a booster fan is possible.

    How old is it.
    Did it work when first installed.

    How many times must one fix something before it is fixed?

    Since it worked most of the winter. Its probably not the inducer its self.

    May be some other restriction.

    What do the install instructions say about that vent length.

    It is a piss poor install.(NOT MINE) It is a super fast condo conversion flip in Chicago. The directions say a 20 foot max and it goes for well over thirty feet. The pipe is clear of nests and the like. I was just hoping the give a little boost.

    As far as I know, there is no draft booster for a 90% furnace.
