Ok so I got a new blower from an HVAC guy in town. Its a monster though 1/3 hp instead of the 1/5 that I used to throttle down with a reostat.
So I was going through all the pages on blowers and I noticed that a baffle is recomended instead of a reostat.
So in order to choke down the intake should I put sheet metal over the sides of the cage? I have it "missing" part of the arch intake right now but its creating some windy side effects in the sugar house and I need to reduce it a bit further.
