This adjustable length of 316 grade stainless steel twin wall flue may also be referred to as a telescopic length. The adjustable length is designed to connect to vitreous flue pipe via a single to twin adaptor or directly to the stove itself. It is ideal for use where a standard 330mm length or a 500mm does not suit your desired structure and you need something in the middle. The length can be easily adjusted to any length measurement between 320mm and 490mm. Made from 316 grade stainless steel. 30mm high grade insulation promotes efficient performance and protects against the build up of condensates within the flue system. All twin wall flue components are CE approved. There is only a 50mm clearance from combustible materials needed when using our twin wall flue. Every twin wall flue component is supplied as standard in stainless steel however we do offer a powder coating service to RAL colours for an additional cost, which allows the components to be supplied to you in a range of different colours to better suit your property. Please contact us for more information regarding this service.
