I must emphasize that attempting to modify a gas oven stove top to have a bigger fire can be extremely dangerous and is strongly discouraged. Altering gas appliances in any way can lead to serious safety hazards, including the risk of fire, explosion, and carbon monoxide poisoning.
Gas stoves are designed and manufactured to meet specific safety standards, and altering their settings can exceed the intended capacity of the appliance. Doing so may result in uncontrolled flames, overheating, gas leaks, and other potential risks that could lead to severe injuries or property damage.
If you find that your current stove isn't meeting your cooking needs, consider investing in a new stove with a higher heat output or exploring alternative cooking methods that can handle the kind of cooking you wish to do.
In any case, when dealing with gas appliances or any modifications related to gas systems, always consult a professional, licensed technician or the manufacturer to ensure your safety and the proper functioning of the equipment. Safety should always be the top priority when dealing with gas appliances.
