11 in. Ventinox VFT Stainless Steel Chimney Liner

Ventinox® VFT is a complete lining system for wood or pellet burning appliances, fireplaces, fireplace inserts and Category l natural gas, propane, or oil appliances.

Ventinox® is a premium quality liner that’s lightweight and easy to use. But don’t let its weight fool you! It’s made of heat resistant 316Ti stainless steel for better high temperature and mechanical strength. It’s formed from a single strip of steel with one continuous weld, so it’s gas and moisture tight. The weld acts like a backbone making the liner strong and workable. VFT won’t pull apart or kink when you make tight, low radius bends!

  • Fastclamp Connect System — Ventinox features the Fastclamp connecting system. No more holes to drill, no more screws or rivets. Simply slide the desired part onto the liner and tighten Fastclamp with a standard screwdriver or socket wrench. Fast and easy to install and ULC Listed. Plus VFT components are made from 316 stainless steel.
  • Zero-Clearance Listed — Ventinox VFT can be insulated with either TherMix or approved ceramic blanket insulation for zero-clearance applications. TherMix is a lightweight masonry insulation that is mixed with water and poured between the liner and the chimney shell. Each UPSable boxed bag makes 3.25 cubic feet of material. Most chimneys require 2 to 3 bags. The ¼" foil face blanket rates 1" clearance to combustibles. Double wrap ¼" or use ½" for zero clearance. Consult manufacturer’s installation instructions for details.
  • Limited Lifetime Warranty — VFT comes with a limited lifetime warranty when used to vent UL listed residential wood stoves, wood-burning fireplaces, pellet stoves, oil-burning heating equipment, and oil-burning water heaters.
