Product Description
Simple, complete and installation-ready flue kits
Narvi Steel Chimney Flue Kit 15 D-125 (Diameter 125 mm) is a high-quality and safe choice for sauna heaters and other heating installations. This well designed, modular kit can be installed simply and easily. Particular attention has been paid with regard to fire-safety and insulation of the flue around the ceiling feed-through. The modular design of the steel flue enables the flue to be installed with a consideration for the specific conditions of a particular building.
The outer casing of the flue is made of zinc-coated steel finished with black heat-resistant paint. The external diameter of the flue is 255 mm. The main flue pipe is insulated with fire-resistant mineral wool. The inner tube with a diameter of 125 mm is made of stainless steel. The flue is also equipped with a permanently installed damper. The Steel Flue Kit is CE-marked confirming that the flue fulfills the requirements of the European fire safety class T600 regulations.
The kit includes all parts and accessories needed for installation and connection of the flue.
