I have a Ventinox SS liner in my chimney, and I understand that there are two types of Ventinox liners (maybe more?): VFT or the High Flex. I'm not able to see which model I have. I know that it is 6 inches in diameter, corrugated inside and out, and fairly firm. I have a small piece of the liner that was cut during installation, but I don't see any welds or anything. How do I know which one do I have? Thank you.

The two current product lines that are offered by Ventinox is VFT and VG. The VFT product is fairly rigid and is manufactured from 316Ti stainless steel. It is used for all fuels, including oil, wood, and pellet. VG is made from AL29-4C stainless steel and is more flexible. It is designed for gas applications.

Both products are corrugated and continuously welded, leaving no noticeable seam. If you have a wood, oil, or pellet appliance, you likely have VFT. A strong magnet should also stick to the VG, but will not stick to VFT.
