FAQs
InnoFlue® Lite is a lightweight, CE EN 14471-certified polypropylene venting system designed for use with Category II and IV gas-fired appliances in the U.S. and for air intake applications only in Canada, as it does not meet ULC S636 requirements for exhaust venting.
Yes, InnoFlue® Lite is the perfect solution for air intake in Canada.
No InnoFlue® Lite does not meet ULC S636 requirements for exhaust venting. However, it can be used for air intake, being price comparible to PVC.
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. 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.
InnoFlue® Lite can be field cut to length using a hacksaw and miter box or equivalent. InnoFlue® Lite must be cut on the male end of the pipe, preserving the socketed (female) end. After making a cut, the end can be beveled at the contractor’s discretion. The end must be deburred using a standard deburring tool or sand paper.
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.
Yes, InnoFlue® Lite works seamlessly with standard InnoFlue® and InnoFlue® Flex components and accessories, including terminations.
Yes. Apply Centrocerin (water-based lubricant) or water to the male end to ease insertion into the female socket.
A rain cap is not required, but bird screens are recommended and may be mandated by local codes.
The polypropylene material has inherent insulating properties. For extreme cold outdoor environments, mineral wool and aluminum cladding may be used.
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.
No Solvents or Glues Required, Faster Installation Time, Superior Temperature Resistance, Environmentally Friendly & Safer, Lightweight & Durable, Flexible System Options.
InnoFlue® Lite is sold in effective lengths of 2′ and 3′, 6′. Effective length is the distance between the male end and the beginning of the female socket. Overall length includes the socket. When assembling/laying-out a system, always utilize the effective length.
The maximum continuous vertical vent length is 164’ (50m).
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.
In Canada, InnoFlue® Lite is only approved for air intake.
InnoFlue® Lite's gasket technology allows for the rapid installation of the system. InnoFlue® Lite can be installed without roughing in the system or penciling the elbow locations as InnoFlue® Lite components can be rotated in place and disassembled. The use of gasketed vent systems reduce installation time by up to 75% when compared to glued systems.
Heating appliances connected to InnoFlue® Lite can be fired upon completion of the vent system unlike glued systems which require a 24-hour curing period.
