I currently have a B vent fireplace. Can I replace it with a direct vent? Do I have to replace the pipe through the roof or use what is there?

Our Answer:

A B vent type of fireplace certainly can be replaced with a direct vent model. However, the venting system is different. A larger direct vent pipe, usually 7 inches in diameter, must be used. If you have a 9 inch by 9 inch area to contain the pipe, retrofitting to a direct vent fireplace would be fairly easy.
