The Flue Damper helps to reduce the up-draught within the chimney.
A flue damper is a butterfly valve encased in the pipe length. The more air that goes in a stove, and the more draw through the flue - the hotter it burns.
A damper allows you to reduce the draw through the stove and therefore reduce the heat output.
It is not essential unless you have problems of excessive flue draft.
For use on solid fuel and gas/oil appliances. eg: wood burning stoves, gas, coal effect fires, oil boilers, solid fuel appliances. Insulation: compressed rockwool, all parts fully welded. Distance to combustibles is 60mm. (e.g. wood, plaster board).
