Step by step:


1) Cut the four angle brackets to size using a hacksaw or angle grinder/disc cutter.

2) Secure the angle brackets into the four inside walls of the chimney using suitable screws/fixings. Aim to have the plate sat just above the opening height of the chimney, so that it is just out of sight but not too high.

3) Cut the plate to size using a hacksaw/disc cutter. Whether you trim some from the back edge or the front or a bit of both will determine how far the stove sits forward/back in the chimney.

4) If you are not fitting a flue liner, it is a good idea at this stage to either cut a square access hole in the plate to one side of the centre, retaining the cut out section to use as a door. Alternatively the plate can be cut in half from front to back so that the plate is in two equal halves and can be lifted out independently when cleaning access is required up the chimney.

5) Move your stove into position lining its flue outlet up with the hole in the plate above. Push the plate up the chimney further so it is out of the way, or if you have cut it in half, simply remove the two halves.

6) Put the pipe into your stove collar. Drop the plate back down and over the pipe, to rest on its brackets.

7) Use the rope gasket to press between the pipe and the hole in the plate to close the gap.
