A new type of furnace - The House-Burner-Downer!
This is a wall furnace. A-may-zing.
Wall furnace after I replaced it and ran a new thermostat line.
That little misaligned flap in the upper right has been driving me batty ever since I noticed it in the picture. Maybe I should head over and fix it. "Hello ma'am and sir, my OCD demands entrance into your property so I can make your furnace cover flaps perfectly aligned again."
