DuraVent 46DVA-CL34KFB DirectVent Pro 3×4 Co-Linear Reline Kit Aluminum

DuraVent is the first manufacturer to have a UL-listed relining system for factory-built chimneys. Our co-linear direct vent relining system can be used when installing a direct vent insert into an existing factory-built chimney. When an insert is installed into an existing factory-built chimney or b vent, relining the existing chimney is critical for proper performance and safety.

Note: Plate must be larger than the current pipe or conduit (Bottom Plate Dimension 14″). Fold brackets into existing diameter to secure the high-wind termination cap in place. Flex does not need insulation!!!

Factory-Built Reline Kit includes:

High-Wind Termination Cap
Two pieces of Aluminum Flex Lengths (exhaust marked red)  (1) 3”x 35’ Length, (1) 4”x 35’ Length
4 hose clamps

Bottom Plate Dimension 14″
