This study investigates the result of thermal stress analysis on burning plate by classes at outdoor gas boiler. In the analysis results at the steady state, the maximum stress and deformations are 666,8MPa at A type and 0.20476mm at B type respectively. The deformation becomes larger as the field goes on from the center to the outside at burning plate. As there are 8 types in the order of maximum stress and deformation, F and C type have safest among 8 types respectively. Therefore, F type becomes most excellent on strength and safety among 8 types. By using the analysis result of burning plate model at gas boiler, it is possible to design the model applied practically at the safe component parameters of boiler system.
