Flow Through Humidifier On Down Flow Furnace?
I've been asked to install a flow through humidifier on a down flow furnace. The furnace is on the main floor, the return comes from the attic, and the supply is below in a crawl space just below the furnace. I've never seen this setup. Can it be done and if so should it be on the supply or return side. Thanks for any input.
