10 feet from the chimney or 10 inches? If it is 10' away, should I then put up two vents, equally spaced from the chimney, near the edge of the roof? Or does that matter if I only put up one near one edge?
Re: Side vents? Ya, I think there would definitely be a lot of work cutting that stuff out. Plus, I don't want to risk cracking it if I use too much pressure with the saw.
I will take a couple of pictures and post them up so that I am 100% clear. Thanks.
