Ventinox chimney liner is available in three different stainless steel alloys to meet all your relining needs. All are top quality stainless steel, and the liner is engineered with a continuous welded seam — the only flexible liner on the market with a welded seam, giving it maximum strength. Whether relining an unlined chimney or a chimney with a damaged liner, Ventinox Chimney Liner is the premium liner to use.
The VFT chimney liner is constructed of 316Ti stainless steel and can be used for all fuels. It is best suited to withstand the corrosive elements and temperatures typical for oil and gas venting systems. However, 316Ti stainless is also strong enough to withstand the high temperatures of woodburning. 316Ti is typically used in marine chemical environments, pressure vessels, chemical storage tanks and now, commonly, for chimney lining. Either TherMix or ProFoil insulation should be used according the installation instructions. VFT features a lifetime warranty for wood, wood pellets, oil and category I gas fuels. A 10-year warranty for coal is also offered.
The Hi-Flex, made of 321 stainless, is used for wood burning and wood pellet burning applications. It can withstand severe heating conditions and is warranted even after a chimney fire. This type 321 stainless steel resists intergranular corrosion at high temperatures and maintains its strength. This alloy is so heat resistant that it is typically use in aircraft afterburners. Either TherMix or ProFoil insulation should be used according the installation instructions. High-Flex offers a lifetime warranty when used to vent wood and wood pellet appliances.
VG, made of AL-29-4C stainless steel is designed to vent gas burning appliances. This type of stainless withstands the corrosive elements and condensates typical in gas flues. This stainless has extreme resistance to chloride pitting, crevice corrosion, stress corrosion and cracking. Insulation keeps the flue gases warmer which enhances draft. Refer to the installation instructions for specific requirements. This steel is typically used in power plant condensers and heat exchangers. VG features
These chimney liners offer the best balance of corrosion resistance, flexibility and cost. They incorporate the use of FasNClamp components, which makes relining chimneys quick and easy. Just use a screwdriver to tighten the clamps on the stainless steel tee, tee cover and rain cap. The top plate has a raised lip to prevent moisture from entering the chimney.
Ventinox Direct Connect Systems make the connection from the appliance to the chimney when the chimney is appropriately sized and passes code. Typically, a tee or insert boot, length of flex pipe and damper sealing kit make up the kits.
