I just took the grate off the furnace, it's right under the refrigerator. I turned on the heater. Their was so much hot air blowing out of the metal furnace enclosure. Their are 6 "Knockouts" for additional ducts? Only one out of the six has a duct connected to it, it's a 2" flex hose that appears to go down in the under belly. 3 of the other knock outs were loose with a lot of hot air blowing out right under the fridge. I got them all tight and sealed them with Flex Seal. Then the furnace pushes the heat to the door that I removed, it appears that when the air hits the door it's forced down into a duct that leads under the floor to the registers. When I reinstalled the door and turned the furnace on hot air was blowing out the door seams, so I sealed all the way around the door. Now their are no leaks around the furnace. It made the 2 registers down stairs blow even harder then before. The bedroom heat was increased slightly but not even close to the down stairs. Before I can start removing wall in the basement, I have to remove all our CRAP we have in their.
