Attention Fireplace Experts! Question 4 U all....
We would like to do a total makeover on our fireplace.
We have 2 vents on either side of the fireplace box that we would like to cover over. They are not directly connected to the firebox, but they do convect heat from the cool air drawn into the bottom vent and will give off some heat through the top vents if the fire is hot enough. We typically only burn Duraflame type logs, not real wood, so they rarely get real hot, but I'd like to make sure it's safe for any kind of fire. See picture below.
My question is, how can I safely seal off these vents? Is there a way? I will be covering the lower vent with a wood surround and marble, and the upper vents will likely be covered with the mantel and sheet rock.
Can it be done????
