Question

Hello, I have a bad downdraft in my wood-burning fireplace chimney, so bad that I need to seal up the glass enclosure in the winter. There's a flue closure that doesn't close tightly, but even if that was repaired I don't believe it would solve the problem. which I've been told is due to the height of the chimney and the cold outside wall. I'm considering making this a gas burning fireplace, which I'm assuming will involve some sealing up of the flue? Will this solve my downdraft problem?  !

Answer

You need to solve the problem of negative pressure in your home.

Do NOT install gas logs without solving this issue. If you do, you might have a serious CO problem.

I recommend you contact a local CSIA Certified Chimney Sweep who is trained in solving negative pressure issues to do some on-site diagnosis of your problem and to offer some solutions.

You can find a CSIA Certified Chimney Sweep at www.csia.org.
