Connects 100mm (4 inch) flue liner to 80mm (3 inch) black stove pipe at the bottom of the chimney stack.
Made from 316 grade stainless steel, it has an integral drain hole which allows condensates to flow back into the flue.
Connect the bottom of the flue liner to the twin wall section of the adaptor, using stainless steel self tapping screws. Seal the joint with either fire cement or high temperature silicone sealant. You can now connect the adaptor to your connecting stove pipe using fire cement or high temperature silicone sealant.
