Technical Data

    The INCREASING ADAPTOR TO CHIMNEY LINER 5" TO 6" connects single wall stove pipe to a Flexible Flue Liner of a one inch increased internal diameter. This steel adaptor has a twin wall top end to accommodate the Flexible Liner which can be secured in place with a High Temperature Fire Cement and self-tapping screws (not supplied). Please note, this item will increase from a 125mm stove pipe to 150mm Flexible Liner. For a connection with the same internal diameter, please see our FLUE ADAPTOR TO CHIMNEY LINER.


    Vitreous Enamelled flue parts have a male connection to push fit inside the pipe or stove outlet below to ensure deposits within the pipes run down into the stove and do not escape. The male connection is always fitted facing downwards as pictured. It is advisable to seal all single wall joints with a suitable high temperature sealant. It is safe to cut single wall flue down to size for a perfect fit.


    Vitreous Enamelled flue is constructed from laser welded steel. These pipes are not insulated.


    All single wall flue supplied by Glowing Embers is fully CE approved for installation in compliance with UK building regulations.

    Flex Adaptor


    Designed for internal use, it is against regulations to pass single wall flue through any surfaces due to the heat emitted from the pipe. The safe clearance to combustibles is three times the diameter of the flue or one and a half times the diameter to non-combustibles. It is advised to limit a run of single wall flue to 2000mm to prevent the loss of heat through the pipe which can lead to flue gases dropping. Please see our Technical Information section for easy to understand guides for all the Building Regulations involved with stoves and flues.

    For further information on using Vitreous Enamelled flue in your system, please see our Chimney Installations page or Non-Chimney Installs section
