In this combustion inspection step, when the operation is performed for the purpose of combustion inspection, the carburetor is preheated by a carburetor heater provided in the combustion section, and when the ignition command temperature is detected by the carburetor temperature detection device, the ignition operation is started. If the flame current is normal, the process proceeds to the ignition limited combustion, and the maximum ignition limited combustion time B is set by previously shortening the ignition limited combustion time in the combustion inspection process from the time when the user normally uses it. When the maximum ignition limited combustion time B has elapsed, the ignition limited combustion is terminated, and the combustion shifts to the strong combustion set in the combustion inspection process.

Therefore, in the control operation of the above-described conventional combustion inspection process, the energization pattern of the carburetor heater is set by the same operation as when the user normally uses the energization pattern of the carburetor heater. Since the full-wave, half-wave during ignition, half-wave for ignition-limited combustion, and half-wave for strong combustion, even if the maximum ignition-limited combustion time B elapses, the control temperatures for strong combustion and ignition-limited combustion are equal beforehand. The ignition mode is switched to strong combustion without reaching the control temperature TH at the time of ignition-limited combustion set to the temperature, so that the ignition state can be confirmed in the actual use state, but the temperature of the carburetor is sufficient at the time of strong combustion to confirm combustion. It was difficult to distinguish between normal and abnormal combustion conditions, and it was difficult to maintain and stabilize the combustion performance of mass-produced products.

Also, during ignition limited combustion after ignition, the components such as a carburetor, a burner, a pump, and a duct constituting the combustion part are low in temperature and unstable in combustion because they are immediately after ignition.
It is meaningless to evaluate the combustion at this time, and the user cannot take much time to stabilize in the strong combustion of the rated calorific value to obtain a temperature condition close to the time of the ignition-limited combustion that operates at the time of normal use, For this reason, the inspection control does not increase the inspection accuracy and is inconvenient.

As described above, the control circuit 14 for controlling the combustion section 3 by an operation different from that used when the user normally uses the apparatus is limited to the combustion inspection step on the production line. It can be confirmed in the state. In addition, since the combustion test is performed under the condition of a stable combustion state in which the temperature of the carburetor 8 has sufficiently increased at the time of strong combustion for confirming combustion, it is easy to distinguish between normal and abnormal, and the combustion performance of mass-produced products The trouble of maintaining and stabilizing is solved.

Further, the time for sufficiently raising the temperature of the carburetor to the temperature condition of the carburetor close to the lapse of the time of the ignition-limited combustion which is operated when the user normally uses, and stabilizing the combustion in the strong combustion for obtaining the rated calorific value. Can be inspected in a stable combustion state at the time of strong combustion to confirm combustion, which makes it easy to distinguish between normal and abnormal,
Inspection accuracy is increased, and maintenance and stabilization of combustion performance of mass-produced products is facilitated.
