Flexible Chimney Liner Kit 6 inch x 35 Ft with Tee Connector

What's in this kit

This is a complete tee-connection kit. Every part is matched to work together, so you do not have to source components separately.

• ◰ Flexible chimney liner (316Ti stainless steel) Runs through your masonry chimney and carries the exhaust safely to the top. Made in the USA and UL 1777 listed. 316Ti is a high-grade, corrosion-resistant alloy that expands when it heats up and contracts as it cools, which helps break loose creosote build-up. Inside-pipe thickness 0.005 in.
• ⊢ Tee connector with removable snout & clean-out cap Connects the liner to your stove or appliance from the side, or where it passes through a chimney thimble at a 90-degree angle. The liner runs straight up from the tee; the snout connects to the appliance. The snout is removable and can be cut shorter with a hacksaw if needed. The clean-out cap on the bottom lets you sweep and inspect the flue.
• □ No-sag / no-leak top plate Seals the top of the chimney and supports the liner. The sloped design lets rainwater run off instead of pooling and leaking into the flue. Strong enough to stand on without sagging.
• ▲ Rain cap with screen & wind guard Sits on top of the liner and keeps rain, snow, animals and debris out of the flue. The screen blocks sparks and nesting, the wind guard helps protect draft. Clamps onto the top plate collar with just a screwdriver.

Choosing the right size

The diameters listed are inside diameters (I.D.). Add roughly 1/4 in. for the outside diameter, and allow an extra 1/2 in. of clearance for the tee body when checking if it fits your flue. Match the liner diameter to your appliance's outlet.

How the installation works

1. Clear the chimney of any obstructions and old debris.
2. Open up enough brick and mortar at the base to give the tee snout access through the chimney wall.
3. Attach the tee to the liner and feed the assembly down the chimney until the tee rests at the base.
4. Fit the snout and the clean-out cap, then seal around the tee with furnace cement.
5. Slide the top plate over the liner at the top and center it to seal the flue.
6. Clamp the rain cap onto the top plate collar. Done.
