The amount of gas used in a gas roasted sweet potato stove depends on many factors, such as the number, size and shape of the roasted sweet potatoes, the power of the stove, the calorific value of the gas, etc. Generally speaking, the greater the number of roasted sweet potatoes, the greater the amount of gas required. According to general experience, if you use a fully automatic gas-fired sweet potato oven, the gas consumption for each time you bake sweet potatoes is about 0.5 cubic meters, which is about 0.005 cubic feet. However, the specific dosage needs to be adjusted according to the actual situation to ensure the quality and safety of baked sweet potatoes. It is recommended that when using a gas-fired sweet potato oven, you should follow the manufacturer's instructions and safety tips, and perform regular maintenance and inspections on the gas-fired sweet potato oven to ensure effectiveness and safety.
