The dial on the right goes round about once for 10 minutes of gas to
heat up the oven. However the digits don't advance.

The printing below the maind numbers shows the max flow rate of 212
cubic feet per hour and the amount of gas per revolution of the dial
0.071 cubic feet.

I have no idea how to interpret the meter's reading. I think the pic
above shows "9612.90" cubic feet. Is that right? Maybe the dial has to
rotate 100 times to move this to "9613.00".

14 times (more or less) 1/0.071 = 14.084.
