Napoleon GDI-320KT 20ft Flex Vent Kit, 3"

Efficient Venting for Standard Masonry Chimneys

The Napoleon GDI-320KT Flex Vent Kit is a comprehensive venting solution designed for the installation of gas fireplace inserts into standard-height masonry chimneys. This kit provides 20 feet of flexible aluminum liner, offering a continuous run from the fireplace appliance to the chimney termination point. By establishing a dedicated path for combustion, this kit ensures that your fireplace insert operates safely and achieves its maximum rated efficiency.

Dual-Liner System for Direct Vent Technology

This kit utilizes a two-liner system, consisting of two separate 3-inch diameter flexible pipes. One liner is dedicated to drawing fresh outdoor combustion air into the firebox, while the second safely vents exhaust gases out of the home. This direct vent configuration is highly efficient because it does not deplete heated room air for combustion. The flexible aluminum construction allows the liners to easily navigate offsets or tight transitions within an existing chimney flue that would be impossible for rigid piping.
