RegulusFLEX Flexible Flue Gas System

A modern flue gas exhaust system for condensing gas boilers.
The flexible pipe can be easily bent and cut anywhere. After cutting to the desired length, a socket is attached to one end and a rigid pipe section to the other. This prepares the flexible section for connection to any rigid flue component—elbows, tees, nipples, etc. Inside the chimney, the pipes are centered using centering parts, and at the outlet, they are terminated with a chimney cap and cover plate. This significantly simplifies flue installation and reduces the time required for installation.

The basic components of the system are the flexible pipe and the chimney kit. The chimney kit includes a chimney cap, a base elbow, and centering pieces. It also includes a flexible pipe end fitting set, which allows the flexible pipe to be connected to other system components.

As additional components, it is possible to add a tee with an inspection port to the system, or other parts commonly used for a simple 80 mm diameter system. To insert additional parts into the flexible pipe, you can order an additional set of fittings (1x socket, 1x pipe). Individual components of the chimney kit can also be ordered separately.
