Can inserts by installed into factory-built fireplaces, or just masonry fireplaces?
Both. A Gas Fireplace Insert can be installed in an existing masonry fireplace or in a factory-built metal fireplace, or built-in like a conventional fireplace. (We offer a zero-clearance kit for this.) Q: Am I limited to a certain size of Gas Fireplace Insert? A: No. There are several sizes available in both natural vent and direct vent models. Two things determine the size: one is the dimensions of the fireplace itself, to make sure a specific insert will fit; the other is the heat output you desire.
