Bosch Gas Stove burner flames too high
Is your Bosch gas stove flame too high? The burner air mixture is the most likely cause. An improperly adjusted air shutter can allow too much gas or air, producing a high, lazy, or hissing flame, although many newer Bosch ranges use fixed air shutters. Next, check the burner cap. A cap that is tilted, warped, damaged, or not seated correctly on the burner base can make the flame higher on one side. Turn off the gas stove and let the cooktop cool before repositioning or inspecting the cap. If every burner has a high flame, the pressure regulator may be incorrectly adjusted, set for the wrong gas type, or failing. A qualified technician should test or replace the regulator. A wrong orifice, or a burner orifice drilled too large for the gas supply, can also cause a gas burner flame too high. Check the installation instructions and parts diagram before replacing it. Enter your Bosch range model number to find the exact pressure regulator, orifice, or surface burner cap for your appliance.
01 - Burner Air Mixture Not Adjusted Properly
Some burners have an adjustable air shutter just before the orifice. If the air shutter is not adjusted properly, the flame will hiss from too much air or too little air will result in a lazy high flame. Most newer ranges have fixed air shutters that are not adjustable.

02 - Burner cap not on properly
Since burner caps help distribute the gas evenly around the burner, a burner cap that is not positioned correctly on the burner base can cause the burner not to heat properly. Confirm the appliance is turned off and the stovetop is cool to the touch, then readjust the burner cap, if necessary, so it is seated properly on the burner base. If the cap is damaged or warped, the flame can be higher on one side than the other. Inspect the burner cap for damage; a damaged burner cap will likely need to be replaced.
Common
03 - Bosch Range/Stove/Oven Pressure Regulator
A pressure regulator is needed on a gas range to keep the pressure constant. If the pressure regulator is not adjusted properly, or is set for the wrong type of gas, the flames can be too high. This will affect all the burners. If you suspect the regulator is bad or not adjusted properly it is best to have a qualified technician check, adjust, or replace the regulator if needed.

04 - Wrong Orifice Installed
To work properly all burners need the correct orifice for the type of gas that is being used. If the burner flame is too high, either the gas pressure is too high or the orifice is too large. Check the parts diagram or the installation instructions for the proper burner orifice.
Common
05 - Bosch Range/Stove/Oven Orifice
All orifices are drilled and numbered according to the size of the hole. If the wrong orifice was installed in a burner, the flame can be too high. Make sure the correct orifice is installed in the burner.
Less Common
06 - Bosch Range/Stove/Oven Surface Burner Cap
A surface burner cap needs to be seated flat on the burner base for the flame to be evenly distributed. If a burner cap is tilted, the flames will be higher on one side than the other. If the cap is damaged, it will need to be replaced.
