Co-Axial to Co-Linear Appliance Adapter

The Co-Axial To Co-Linear Appliance Adapter is used to transition a direct vent gas fireplace with a 4" inner and 6 5/8" outer exhaust hole to a co-linear 3" exhaust and 3" air intake venting system. This is great for when you want to install a direct vent gas fireplace inside a masonry fireplace. Co-linear venting is essential when using a direct vent gas fireplace as a fireplace insert. Oftentimes the chimney for a fireplace makes a bend around the damper and smoke shelf which makes it difficult installing the solid direct vent pipes. Transitioning to co-linear venting allows you to install two 3" flexible liners for the exhaust and the fresh air intake. Note: You must first check with the direct vent fireplace installation instruction to determine if the co-linear chimney venting is approved with your direct vent fireplace.
