the under
fridge area had a 4" and a 2" heat duct laying on the floor and crossing one over the other....totally useless space
I decided to dig into the situation.....taking the floor of the closet out (to expose the furnace) I found that the
propane line access hole (through the floor) had never been sealed.....the floor was BLACK from a dozen or so years of road grime making it's way into the space
I took the three heat ducts off the
furnace, cleaned up the floor. I sealed the hole from the outside....then I rerouted the heat ducts so they would be out of the way as much as possible and reconnected them.
extra space.....always a "good thing"....
