Crown Mount Co-Linear Chimney Caps are the best option for venting a gas or pellet fireplace insert or stove in a masonry chimney. This unique chimney cap can accommodate the exhaust as well as the fresh air intake. No need to cut a hole in the side of the home, utilize the chimney for all your fresh air needs. The cap separates the exhaust and fresh air intake to ensure that the exhaust gas doesn't get pulled down the intake line. The Crown Mount Co-Linear Chimney Cap is fixed on a 17" x 17" plate and is available in either a 3" exhaust with 3" air intake OR 4" exhaust with 3" air intake. The Co-Linear Chimney Caps are constructed from 304L stainless steel and equipped with quick-connect collars to easily attach the liners to the chimney cap.
