Facing material over direct vent fireplace
We have a Marquis Infinite, 33,000 BTU direct vent gas fireplace inserted a few months ago, as part of a big renovation. There's a TV above the fireplace, and we have been taking our time deciding what to face the wall with.
We finally turned the fireplace on the other day, and after about an hour, the area immediately above the fireplace (which is cement board right now), got so hot, we could barely touch it. We definitely know that the fireplace has been properly installed.
We recently ordered textured glass which the contractor has said he will make tempered, however, he can't guarantee that it wont brake due to the heat.
Help!!! Has anyone faced their fireplace with tempered glass products or had any concerns with overheating right above the fireplace?
