in at that point. Wa-ay too much gas will be created. Avoid
this by blocking the air entry hole and opening one under
the grate, just below the upper right end. The area of the

<br>
The primary air hole should be 30x120mm? With a valve so its
adjustable?<br>

<br>
You mean the 'throat' from hopper (A) to combustion area (B). Third
of the hopper width would be about 7cm. 7x7 then?<br>

Yes I was thinking of having a window in the door into the
combustion area.<br>
