How to Install a Twin Wall Flue System

Our Chimney flue truly is a 'Fitters Choice' as it comes in all the possible diameters required, with all the possible components for commercial and domestic applications and with the ability to increase flue size going up as necessary. It is a simple push fit joint system that is both fast and easy to install and comes fully welded to ensure a superior finished twin wall system (60mm to combustibles). Please ensure that the finished system is as vertically straight as possible. All domestic flue installations should be carried out by a HETAS approved installer. For condensing applications please order and fit and seals with each component.

The chimney should remain as straight as possible and be high enough to ensure sufficient draught to clear the products of combustion. The height necessary for this will depend upon the type of the appliance, the height of the building, and the number of offsets within the system. However, a minimum flue height of 4.5m should be achieved as recommended in the Building Regulations. All chimneys must comply with the Clean Air Act. The size of the chimney system should be as recommended by the appliance manufacturer and in most cases should not be smaller than the appliance outlet.

This is a modular single skin chimney system manufactured to BS EN1856-1, constructed from AISI 316L fully welded liner and is CE approved. It is suitable for gas, oil and solid fuels and for dry, condensing (wet) or non-condensing applications. We would recommend using our twin wall flue systems for Biomass flue installations.
