Zero clearance has two meanings. The first is whether or not the fireplace can be placed on a floor without footings. All of our fireplaces are classified as zero clearance, meaning they do not need special footings. The second meaning of zero clearance is if you are able to finish up to the face of the fireplace, so that no metal shows after installation is complete. There are several models on our website that are capable of this clean-faced, zero clearance finish. Check with your local dealer on which models are suitable for this type of installation.
