Nordyne Announces Changes to CMF Miller Furnace

Starting December 1st 2006 a new style heat exchanger will be installed in the CMF model furnace. The new heat exchanger will utilize a round heat exchanger with tubular pipes. The old style used a square heat exchanger with a rectangle tube. The new heat exchanger will raise the AFUE ratings and will do away with the chance of a boomer heat exchanger which could happen with the square heat exchanger.
