A zero clearance fireplace is a factory-built unit tested to sit close to combustible framing, so it can be installed in a wood-framed wall where a masonry fireplace would not fit. That makes it the usual choice for new builds, additions and renovations. This page covers wood burning, direct vent gas and vent-free zero clearance models, with brands like Superior, Empire and Napoleon, plus Buck Stove zero clearance inserts. Compare fuel type, opening width, venting needs and the listed clearances. Always follow the manufacturer's installation manual and local code.

Zero clearance fireplace buying guide

Because the firebox is insulated and listed for combustible framing, it has strict rules about the chase, chimney or vent system, and the materials around the opening. Choose your fuel first. Wood models require a certified chimney system and a hearth extension. Gas models are either direct vent, with a sealed pipe, or vent-free, which has local restrictions. Measure the planned location and compare it with the rough-in dimensions for each model. Plan the finish early, including mantel height, face kits and non-combustible surround. Hire a qualified installer for gas lines and chimney connections.

What does zero clearance mean?

It means the fireplace is tested and listed for installation with very little clearance to combustible materials such as wood framing, when installed to the manual.

Can this kind of fireplace be installed upstairs?

Often yes, because it is a prefabricated, lightweight unit, but you must follow the manual for structural support, venting and chimney height.
