Propane stoves typically require a lit pilot light or an open flame to ignite the propane gas and provide heat for cooking. However, some modern propane stoves may have electronic ignition systems that do not rely on a continuous pilot light. Instead, they use an electric spark or a glow plug to ignite the gas when you turn the knob to the "light" position.
If your propane stove has an electronic ignition system, you can turn it on without a lit pilot light or open flame. Simply turn the knob to the "light" position, and the electronic ignition will produce a spark or heat up the glow plug, igniting the propane gas.
On the other hand, if your propane stove does not have an electronic ignition system and relies on a pilot light, you cannot turn it on without a lit pilot light or open flame. Attempting to do so would be unsafe and could lead to a buildup of unburned propane gas, posing a potential fire hazard or risk of explosion.
Always consult your stove's user manual and follow the manufacturer's instructions for safe operation. If you are unsure about how to use your propane stove, it's best to seek guidance from a professional or the manufacturer.
