I have a kitchenaid superba gas stove, the flame is too low on three burners, and very high on the 4th burner, is there an adjustment screw?
Model: Superba Gas Stove
nothing, just getting frustrated with the low flame output, makes cooking difficult
There is no adjustment screw for what you are complaining about. I am answering exactly what you asked.
What is causing the change in flame height?
Gas flows thru the valves and the orifices, so the issue is within either of those areas.
I understand how gas flows thru valves and orifices. The question is what are possible causes for changes in flame height. Gas flows thur the orifice and is ignited by a spark, understood. How can one adjust the gas output?
