Replacing Oil Furnace With Gas
Posted: Mon Nov 08, 2010 1:09 pm
Hi, I am replacing my old oil furnace(approx. 1976 Coleman) with a gas furnace in my mobile home. Gas is now available. Will I have to worry about the BTU output of the new furnace. I am not sure yet as to the size of the duct. I was hoping to be able to put in a used unit with approx. 60,000 to 90,000 BTU downdraft.
Another question I have is about the venting. How can I use the old chimney from the old oil furnace as the vent for the new gas one. If I buy the correct gas unit will I be able to naturally vent. I am trying to avoid tearing the old one out and having to do roof repair. Maybe put the vent inside of the existing one?
