Add 1/4" for the outside diameter of the liner. This kit includes a Vertical Appliance Connector where the liner fits into the female side, utilizing the quick connect band. Use the Appliance Connector when you are connecting vertically to the top of a fireplace insert or appliance. A perfect round fit every time thanks to the smooth weld technology. A 13" x 13" Top Plate with a Quick Connect Collar is also included to secure the chimney liner from the top of the chimney. You can trim it to fit with a pair of snips and it's ready for installation. If you need a larger size or different style, please contact us for details. The Quick Connect Flue Cap with mesh screen will keep animals and debris out of the chimney. Fasten down the quick connect clamp to the collar of the Top Plate and you're done!
