How do I get the manifold pipe loose from the gas valve on a empire 215 direct vent propane heater?

John Mac here...the solution was that we had shut the pilot off for the summer, and birds had made a nest inside the heat exchanger...coming in through the direct vent. Cleaned out the nest, and it works perfectly. My technician recommends that I leave the pilot buring through the summer to prevent this in the future.

Yes, the design of the combustion chamber is limited at how much fresh air and combustion air can enter it. If you lengthen the venting, you will be causing more restriction and there will not be enough natural air movement to make it work. It will start, run for a minute or two and poof out. Not to mention you will be circumventing it's UL rating and if you sell your home with it installed, you are liable for any fatality or damage. Do you want to risk that? Don't even think of doing it! There are "Box" heaters out there sized from about 5,000 Btu's on up to 100,000 Btu's. Check the web.
