>>>The higher BTU gas will cause a few problems, but most of it can still be used.<<<

Yes, I remember when that happened a few years ago. I was using what was originally a coal furnace, installed in 1923, which at that point had a gas conversion burner. The furnace began to sound like a jet plane taking off. As I recall, when it first ignited it sort of half-exploded, though it never blew the flue pipe apart, maybe because the flue pipe was already rotten. Now I have an up-to-date gas steam boiler, though not the extra-high-efficiency. To get that last 10% would have cost about $3,000 extra and would have saved only about $50 a year--$120 maybe with present gas prices. I guess a 4% tax-free return wouldn't be so bad.
