Fireplace inserts are designed to be installed into an existing masonry opening or into zero-clearance fireboxes. As a result, the vent system must be run horizontal. They are not designed for new construction or remodels that you would frame around the unit. However, some of them can offer a clean-burning, more efficient source of heat and even better heating capacity than traditional fireplaces. Our inserts feature compatibility with electric, natural gas, wood and even pellets, so whatever fuel source you prefer or your local area requires, we can provide.
