The Screw Fix adaptor is a threaded metal connector which allows connection to our Multi Fuel Liner by screwing on to the Flex, giving a gas tight seal. The other end allows connection to single wall pipe at the base of the stack.
Connects our 150mm (6 inch) Multi Flue Liner to 150mm (6 inch) Black Pipe / Vitreous Enamel / 1mm Stainless / Single Wall flue at the bottom of the chimney stack.
Made from 316 grade stainless steel, it has a pressed thread that allows it to be screwed to our Multi Fuel Flue Liner giving a gas tight seal. It has integral drain holes to let the condensates flow back into the flue.
1. Connect the bottom of the Flue Liner to the adaptors twin wall section by screwing the adaptor on to the Flue Liner as you would an ordinary nut and bolt, you can apply a small amount of High Temperature Silicone Sealant to ensure a gas tight connection.
2. You can now conect the Adaptor using Fire Cement or High Temperature Silicone Sealant to either your appliance (if the appliance is a solid fuel appliance then you must have a least 600mm of flue pipe before this connection) or Black Pipe / Vitreous Enamel / Single Wall Stove Pipe. If the gap is large between the Adaptor and the pipe you can seal using a combination of Fire Cement / Silicone and Fire Rope.
