Ventinox VFT
Crafted from 316Ti stainless steel, Ventinox VFT is designed to endure the high temperatures generated by solid fuel heaters and the corrosive conditions common in gas or oil vents. It is tested and listed for all-fuel use, making it suitable for wood, gas, and oil-fired appliances.
Ventinox VG
The ideal solution for venting gas-fired appliances where the formation of highly corrosive condensates, such as hydrochloric acid, is expected. Made from super-ferritic AL29-4C stainless steel, this material provides exceptional resistance to chloride pitting, crevice corrosion, and stress-related cracking.
Ventinox components are constructed from either 316 stainless steel (VFT) or super-ferritic stainless steel (VG). Each component includes an integral locking band, eliminating the need for pop rivets and ensuring a secure, penetration-free connection from top to bottom. When venting solid fuel heaters, Ventinox VFT requires insulation with either TherMix or ProFoil blankets to meet UL 1777 standards. Insulation is also highly recommended for all other applications to enhance efficiency and draft performance.
Applications:
VFT flexible liners are used for upgrading or restoring masonry chimneys that vent Category I natural gas, propane or oil appliances, wood or pellet stoves, f ireplaces and fireplace inserts.
VG flexible liners are top performers when used to line masonry chimneys venting Category I gas-fired boilers, furnaces, space and water heaters.
