Ventinox®
Ventinox VFT, made from 316Ti stainless steel, can withstand high temperatures associated with solid fuel fired heaters, as well as the corrosive environments typical in gas or oil vents. Tested and listed for all-fuel, and can also be used for wood, gas, or oil-fired equipment.
Ventinox VG is the ultimate choice for venting gas fired appliances, where highly corrosive condensate formation (hydrochloric acid) within the flue is likely. The super-ferritic AL29-4C stainless steel alloy exhibits extreme resistance to chloride pitting, crevice, and stress corrosion and cracking.
Ventinox® components are made from either 316SS (VFT) or superferritic stainless steel (VG). Components feature an integral locking band, avoiding the use of pop rivets. Liners and components provide a penetration free top to bottom connection.
When venting solid fuel heaters, Ventinox VFT must be insulated with either TherMix or ProFoil blankets to meet UL 1777 requirements. For all other applications, insulation is highly recommended for increased efficiency and draft performance. See the end of the DuraFlex SS for the insulation section to find information on our offering: TherMix, ProFoil, AluFoil Tape and ProMesh.

Planning Your Installation:
| 1 | Verify the venting requirements of the appliance used. Choose the liner system appropriate for the appliance and installation. Note: VFT is recommended for all fuels and VG is the best choice for gas. |
| 2 | Refer to the Typical Installations for the type of liner installation similar to your situation. Identify the needed parts for installation. |
| 3 | Venting for a fireplace requires the correct liner size for proper drafting. The size of the liner should match the outlet size on the appliance. |
| 4 | Determined the length of the liner needed. |
| 5 | If connecting two or more appliances to a common vent, be sure to connect the higher BTU appliance below the lower BTU appliance. |
| 6 | Make sure of a proper fit for the top plate of the relining to provide a secure, leak-proof installation. |
| 7 | If a free standing appliance is used, select the vent or stovepipe pieces to connect from the appliance to the liner (refer to the appropriate Simpson Dura-Vent Catalog Section). |
| 8 | Important! Check to be sure the installation complies with all local and national code requirements, including clearances to combustibles. Contact the local building inspector for permit requirements. |
