Overview
The Forever Flex 6" Appliance Connector Kit is a complete stainless steel chimney liner system for relining a masonry chimney. It's made from 316Ti titanium-stabilized stainless steel, the alloy rated for wood, oil and gas, so one liner covers wood stoves, fireplace inserts, oil furnaces, gas furnaces and water heaters. Buy it from StoveSource and pay no sales tax in any state.
Use it where the appliance or fireplace insert connects straight up into the liner (top connection). The appliance connector joins the liner to the flue collar.
Available in 15, 20, 25, 30, 35 ft lengths. Measure from the top of the chimney crown down to the appliance connection, then add about a foot for trimming.

Sizing tip
Match the liner diameter to your stove or appliance flue collar, and never go smaller than the collar.
Many codes and stove manuals require the liner to be insulated for wood-burning appliances. Check your appliance manual and local code, or choose the pre-insulated version.
Need just the liner? The Forever Flex 6" pre-cut chimney liner comes in more lengths and alloys, sold without the kit hardware.
Insulating your liner? Add the All Fabrications Super Wrap insulation kit in 6". It wraps the liner in a 1/2" insulation blanket before it goes down the chimney, or choose the Forever Flex 6" pre-insulated kit instead.
