InnoFlue® Concentric
InnoFlue® concentric is a highly engineered vent system allowing for the movement of combustion air and combustion gas through a single vent system. The vent system can be integrated with InnoFlue® Single Wall and Flex where applicable. Concentric is available in 2”/4”, 3”/5” and 4”/6” diameters.
Polypropylene and Metal Construction
Laser welded vent lengths and fittings are air-tight eliminating leakage experienced by inferior crimped construction. InnoFlue® Concentric is the only metal/polymeric concentric vent system listed to the rigorous UL-1738 safety standard. Casted elbows and adaptors provide increased impact resistance. The exterior is powder coated which creates a beautiful aesthetic which is perfect for installation in high traffic areas. The polypropylene interior is highly corrosion resistant, making it suitable for both gas and oil fired appliances. The concentric design contains both combustion air and exhaust into one single part. This creates the ability for one single penetration through a roof or wall.
