Yes, you can use an existing chimney with a wood-burning stove if it meets specific requirements. The stove’s vent pipe size must be compatible with the size of your chimney flue. Your contractor can tell you whether your chimney is suitable for installation.

Well-seasoned hardwoods like oak, maple, hickory, and ash are the cleanest woods to burn in a fireplace. When properly dried, these woods have low moisture content, allowing them to burn hotter and produce less smoke, which minimizes creosote buildup. Ensure the wood is seasoned for at least six months for optimal burning.

When your wood stove catalyst goes bad, it can cause your stove to produce less heat or run slower than normal. You might also notice thick black smoke coming out of your chimney. If you notice any of these signs, contact a professional who installs wood-burning stoves and repairs them for an inspection and fix.

In addition to flashing, a roof cricket can help divert water around your chimney so that it drains properly off your roof. It’s shaped like a double triangle and is installed behind the chimney so that falling water spills evenly down each side. This helps prevent water from accumulating behind your chimney, which can increase water damage and the risk of leaks. 

The International Building Code (IBC) requires cricket installation if a chimney built after 2012 measures over 30 inches in width. Chimneys constructed before that date are typically grandfathered in and aren’t required to have crickets installed.
