a/s only installs FFs with 1way switches, blowing OUT.
IF the ff has a 2 way switch, it (the switch) was installed after purchase.
it is possible someone simply reversed the wiring to blow IN only...
or that the 2way switch is kaputt.
if u don't have the install instructions they are downloadable,
and it might be worth fiddling with.
but i agree call the FF folks and they will make it right.
top notch customer service is what they really provide.
all of the true things that i am about to tell you are shameless lies. l.b.j.
we are here on earth to fart around. don't let anybody tell you any different. k.v.
