metal chimneyMetal chimneys: are generally installed within wood chases (an enclosure that looks somewhat like a chimney). The chase is an enclosure which may or may not be required by some jurisdictions. The double or triple-wall chimney vent pipe may be entirely exposed to the weather. The pipe is almost always exposed in attics. The integrity of the metal chimney is very important since a direct vent "fireplace" vent cap terminates outside the same wall the unit is installed against. Separation at a seam or connection would almost certainly result in a fire within the wood chase or attic. Check with a mirror and flashlight often. If you're not sure of what you're looking at you are advised to contact a qualified chimney specialist before each season of use, or at least once per year. Termination requirements of metal chimneys are the same as for masonry chimneys. A simple vent pipe atop a wood stove qualifies as a metal chimney. These are often single-wall pipes prone to rust-out and other failures. These must be checked before each season of use and monthly thereafter.
