Fireplace and Cement Board (picture included)

jburr827April 10, 2009

Hey Everyone,

I am trying to install a new gas fireplace and could use a little help. My specific question is: How does the cement board connect to the fireplace itself?

As you can see in the image, it is clear the cement board has to pass over the nailing strips and butt up against the protruding trim (or at least the tile does anyway). On the sides, can I just put a screw through the cement board and nailing strip into the metal stud? I was told that you should not directly connect the cement board to the fireplace due to the contracting of the unit when it heats up (could eventually crack the tile), but I don't see a way to avoid that here.

Also, how would you handle the top of the fireplace where the stud is set back away from the fireplace itself and the nailing strip is much smaller?

Thank you.

I would add metal studs close in on each side and across the top. Screw the cement board to these additional studs and then let the cement board edges overlap the fireplace flanges without connecting to them. Since the overlap wouldn't be more than a few inches it'll be rigid enough to tile over. There are a few ways to piece in the metal studs. If you need help with that let me know.

We did exactly as you suggested and it worked out perfectly. I often have the confidence to do it, but I just don't know how to do it!

I love this forum and greatly appreciate all of the help I have received from you and others.

Thanks again.
