Claims

[Scope of Claim for Utility Model Registration] 1. A combustion chamber that houses a plurality of burners, nozzles corresponding to each of these burners, a part of the manifold in which the nozzles are installed, and a damper, and that is located in the upper part of the burner chamber in which a blower is attached. In a combustion device in which a heat exchanger and an exhaust chamber are sequentially arranged, the burners are divided into a plurality of groups, and the position of the flame opening of the burner with respect to the height direction of the combustion chamber is changed for each burner group. 1. A burner structure for a combustion device, characterized in that the specifications of a nozzle and/or damper corresponding to each burner group are set so that the positions of the flame tips of all burners are substantially the same. 2. A water heater comprising the burner structure according to claim 1. 3. A bathtub with hot water supply, characterized by comprising the burner structure according to claim 1.
