Installation Simplicity

IL twin wall, air-insulated flue is suitable for gas appliances, typically in domestic or small commercial installations, with draught-hoods or with a flue gas temperature not exceeding 250°C and zero or negative pressure in the flue.

Lengths and fittings push and twist lock together positively to provide a strong rigid flue system and to ensure maximum ease of site assembly.



Jointing System

All lengths and fittings are designed to be installed with the male coupling uppermost. The female swaged coupling of the next component is simply pushed into place and twisted to provide a firm and secure connection.


Gas Flue Box

Designed to accommodate the installation of domestic gas fire and used in conjunction with a traditional or prefabricated chimney.


5 Year Warranty

The IL® range is backed up with a comprehensive 5-year product warranty. The 5-year warranty is a measure of our confidence in the quality and reliability of our flue systems and gives added peace of mind for any installation.
