When my Heat Pump was installed a few years ago we just pulled the old fuel oil furnace over to the side. I'm going to make a run to the scrap metal place next week so I decided to take the old furnace too.
I had to take it out of the basement by myself so I decided to disassemble it and remove it piece by piece. It was incredibly easy. I took a bucket in the basement with me to throw all the screws in but the thang only had a hand full of screws holding it together.
The combustion chamber was too heavy for me to lift but I have an outside entrance (Bilco Door) to the basement so I pulled it over to the steps and laid on the steps against a plank and ran a chain out to the yard and hooked it to the garden tractor and pulled that heavy assed thing right up the stairs.
More room in that little ole basement now.
