Napoleon GDI-325KT Fireplace Venting Kit Liner-Inlet and Exhaust

Complete 25-Foot Flex Venting Solution

The Napoleon GDI-325KT Fireplace Venting Kit is a specialized dual-liner system designed specifically for the installation of direct vent gas fireplace inserts into existing masonry chimneys. This comprehensive kit provides two separate 25-foot flexible aluminum liners, one to handle the intake of fresh combustion air and the other to safely exhaust flue gases. The 25-foot length offers ample reach for most standard two-story residential chimney runs, ensuring a continuous, unbroken path for air exchange.

Engineered for High-Efficiency Inserts

As a factory-authorized accessory, the GDI-325KT is precision-engineered to maintain the pressure balance required for Napoleon’s high-efficiency gas inserts. The flexible nature of the liners allows them to navigate the bends and offsets common in older masonry chimneys without the need for complex rigid elbows. By using this genuine Napoleon kit, you ensure that your insert operates at its rated efficiency while adhering to strict safety codes for sealed combustion systems.
