Do I need a masonry chimney for a zero clearance fireplace?

No, you do not need a masonry chimney for a zero clearance fireplace. These fireplaces are designed to be used with a Class A insulated or air-colled chimney system, which safely vents high-temperature exhaust through the roof. This makes zero clearance fireplaces a flexible and cost-effective alternative to traditional masonry fireplaces that require heavy, labor-intensive chimney construction.
