Well I orderd my Alaska 140 furnace today! Fortuanely my supplier had the foresight to order quite a few in May. So maybe 3 weeks!!
Anyway here is my question. He the supplier recommended ducting the unit into the return air on my exsisting furnace, then use a relay to have both blowers come on at the same time. He also said to run a 8" round into the return air,of the exsisting furnace,. Use no dampers.
So, what do you guys, the experts!!, think?
