  • System 1 Single Wall Flue Systems

    Single-Wall Stainless Steel Chimney System

    The System 1 Flue System is an economic single wall chimney system suitable for non-condensing gas and oil fired industrial warm air heating equipment where the flue gas temperature will not exceed 300°C and where there is no risk of accidental human contact or proximity of combustible materials. Available from 100mm to 350mm

    System 1 Single Wall Flue Systems - Single-Wall Stainless Steel Chimney System

System 1 flue is an economy single-wall pre-fabricated chimney system which has been designed to service gas and oil fired industrial and commercial warm air heating equipment installed predominantly in industrial units. System 1 flue is designed to operate under negative draught and dry conditions.  As this is a single wall industrial product, it is designed to be installed where there is no risk of accidential human contact or in close proximity to combustible materials.  System 1 should be installed at least 3xDia to an adjacent combustible material.  Where the above conditions cannot be achieved then a suitable twin wall product should be used.

System 1 is available in a range of diameters covering 100mm to 350mm internal diameter.
