The Sol Air furnace in my 76 Palm Beach had five 3 1/2" ducts and one 2" duct.
Two ducts going forward to registers under the sofa- one for heat and one for return air.
Two ducts going rearward supplied heat to registers below the closet and drawer bank.
One duct going rearward that terminates in the void behind the generator box. I assume it was also a return air duct.
The 2" duct goes to the bathroom- there is a booster fan in that line behind the stove. If I can make the fan work is it effective in getting heat to the bath? I assume the fan is supposed to run when the furnace blower runs. I never checked it before removing the Sol Air.
The reconditioned Suburban furnace has 2 round duct knockouts on each side (which have all been removed) and one rectangular knockout on the bottom.
It doesn't use ducts to get the return air.
I think I can use the 2 openings on the front side to supply heat to the 2 registers below the couch.
I can't use the openings on the rear because the cabinet is in the way. So I will have to build a plenum to fit under the furnace and use the rectangular opening to supply heat to the two rear registers.
Any reason to NOT connect the third rearward duct to the plenum and have another register discharge out of the back wall under the bed?
Have any of you that installed Suburban furnaces been successful in getting heat to the bathroom? Or is that a lost cause? Did you use the in line booster blower?
All suggestions will be appreciated.
