I've removed the furnace and the combustion box is rusty, as is the air intake tube. I can patch with foil tape. The installation manual suggest blowing compressed air through the combustion chamber. Is this worth doing? I would need to work out how to get the combustion chamber out of the cabinet.
Has anyone replaced their furnace with another unit? Expensive I expect. I am in the UK so would probably want to find a replacement here. ?
Any thoughts gratefully received.
