          Most poorly made appliance I ever bought
          The fit and finish in this heater is abysmal. The jacket doesn't line up with the tank. The draft hood had to be hammered on. And my 14 yr. old could have made better welds, with less splatter. Over-priced junk. Hopefully, it will actually work.
