PROBLEM TO BE SOLVED: To provide a sealed combustion type gas stove capable of enhancing efficiency of energy consumption by setting the quantity of combustion air in standard air supply/exhaust connection to an optimum quantity with simple structure to reduce the quantity of energy in combustion exhaust gas exhausted outdoors. SOLUTION: A connecting air supply connection joint (obtuse angle type) 28 for standard air supply/exhaust is provided with a passage resistance increasing means composed of an internal surface orifice part 29, and the supply quantity of combustion air in the standard air supply/exhaust connection is set to the same degree as the supply quantity of combustion air in extended air supply/exhaust connection in maximum allowable conditions. The connecting air supply connection joint (obtuse angle type) 28 for standard air supply/exhaust, and an air supply connection joint (right-angled type) 26 can be easily identified in appearance because of different shape.
