Technical Data

    The 1000mm Straight Length pipe is used to create the main run of your chimney system


    KW Pro Range

    The KW Pro system has been designed for use all solid fuel, wood, coal, gas, oil and pellet heating appliances. It has been tested to a maximum operating temperature of 600°C and comes with a 25 year warranty.

    KW Pro has exceptional thermal properties which have allowed it to be classified as G50. The 25mm high density mineral insulation is injected into the cavity of the chimney under high pressure; this improves the thermal efficiency of the system which in turn helps maintain constant and reliable flue performance.

    The KW Pro range has the largest selection of starting components of any chimney system available in the U.K. This enables you to complete the installation with the most aesthetically pleasing transition from stove to chimney possible.

    Locking bands are included with each component as required; the standard locking band will provide lateral support for up to 1.9 metres of pipe above the final wall support. Structural locking bands are available and allow an additional metre height.

    KW Pro is suitable for installation on both dry and condensing appliance applications. (Silicone seals are required for condensing appliances).

    The KW Pro range of flue products carries a 25 year warranty which covers manufacturing defects. Provided that the system has been correctly installed and used as per the installation instructions. As with all chimney systems it is imperative the flue is swept on an annual basis by an approved chimney sweep and a signed record of this is maintained. Where solid fuels are burned, these must only be fuels approved and specified by either the solid fuel association or HETAS. The use of any other fuel will invalidate the warranty, as will any evidence of a chimney fire. The powder coated surface of a coloured flue has a 2 year warranty
