FAQ
InnoFlue Lite is a lightweight, CE EN 14471-certified polypropylene venting system designed for use with Category II and IV gas-fired appliances (U.S.) and Class II C appliances (Canada). It is suitable for residential, commercial, and industrial applications with flue gas temperatures up to 230°F (110°C) and maximum pressures of 0.725 psi (5000 Pa).
Yes. Use paints approved for polypropylene, such as Rust-Oleum or Krylon. Remove ink markings with acetone, apply an appropriate adhesion promoter, and reattach the product label once dry.
Use Centrotherm-supplied support brackets when possible. Horizontal runs must be supported every 39" (1 m); vertical runs must be supported every 78" (2 m). Directional changes (elbows/tees) should be supported within 12".
Yes, InnoFlue Lite is the perfect solution for air intake in both code and non-code markets.
Yes. All diameters of InnoFlue Lite SW Rigid components are UV stabilized and suitable for exterior installation. Optional black components are available in 2" and 3" for aesthetic preference or enhanced performance.
Not directly. For underground applications, InnoFlue Lite must be installed inside a larger diameter, direct-bury-rated pipe. The vent must be pitched, supported, and allowed to expand/contract inside the sleeve.
InnoFlue Lite is designed to withstand flue gas temperatures up to 230∘F (110∘C).
No Solvents or Glues Required, Faster Installation Time, Superior Temperature Resistance, Environmentally Friendly & Safer, Lightweight & Durable, Flexible System Options.
InnoFlue Lite is approved for gas-fired Category II and IV appliances and is suitable for vertical or horizontal venting in new or retrofit installations, including chimneys, chases, and through-wall terminations.
Yes, InnoFlue Lite works seamlessly with standard InnoFlue and InnoFlue Flex components and accessories including terminations.
The polypropylene material has inherent insulating properties. For extreme cold outdoor environments, mineral wool and aluminum cladding may be used.
A condensate drain should be installed as close to the appliance outlet as possible, especially for horizontal runs over 50 feet—unless the appliance manages condensate internally.
Yes, provided the chimney or B-vent is structurally sound and not shared with other appliances. Use base supports, spacers every 78", and avoid spray foam or mortar.
Yes. All components are factory-equipped with gaskets. If a gasket is damaged or missing, replace it with a genuine Centrotherm part. Clean gaskets and gasket beads before assembly.
Yes. Apply Centrocerin (water-based lubricant) or water to the male end to ease insertion into the female socket.
Horizontal runs must pitch back toward the appliance at a minimum of 1° or 1/4" per foot (2.1 cm/m) to ensure proper condensate drainage.
In exterior applications, a single stainless steel screw may be used to secure direction. Octo Clamps are required for 2" and 3" diameters under CE EN 14471 compliance.
The InnoFlue Lite Octo Clamp is engineered to provide enhanced support on all pipe fitting connections, reducing the risk of leaks and joint failures. It also integrates a 3/8 " threaded rod to support the weight of the vent system.
Maintain a minimum of 12" from the termination to grade or anticipated snow level. Do not extend more than 12" from the exterior wall. Follow local codes for specifics
A rain cap is not required, but bird screens are recommended and may be mandated by local codes.
Yes. For rooftop terminations, follow flashing and sealing instructions. Vertical terminations over 59” above the roof line must be supported with guy wires or braces.
