I am refinishing my basement and having trouble meeting the 50 cf of open air / 1000 btu of input on my furnace. I have heard that some manufactures offer a direct vent system for air intake that would use standard piping. Any online sources for researching this. Tried Weil Mclain's web page unsucessfully. Trying to avoid venting entire room to outside w/ louvers.
