Abstract: A gas-fired clothes dryer, where a mounting base is disposed in a housing, a gas-fired heating device is connected to a mounting frame, and the mounting frame is detachably connected to the mounting base; and the housing is provided with a maintenance port, the maintenance port directly faces the mounting base, and the maintenance port is arranged to allow the gas-fired heating device and the mounting frame to pass through. Through the above arrangement, for replacing a burner, the mounting frame is detached from the mounting base through the maintenance port, and then the gas-fired heating device and the mounting frame are moved out of the housing from the maintenance port, so as to replace the burner on the gas-fired heating device, making the whole process convenient and fast, saving the maintenance time and reducing the maintenance cost.
