Hi, Folks!
Anyone run into a problem getting a big enough heat exchanger to fit their furnace? We have a Lennox Elite oil furnace with an A/C coil on top. The coil is almost to the top of the plenum. The heat ducting is only 12"x23" where it exits the plenum. That might be a little small. I could probably install at an angle to get a larger exchanger to fir there.
Another suggestion is to install the exchanger in the cold air run. Will a blower motor survive 180 deg. cooling air without overheating?
My B-I-L installed his on top ot the blower, but again, I have even less space there, unless I cut a relief in the bottom of the furnace.
Any thoughts?
