A fixing plate for the thermal insulation material is attached to the combustion plate flange part. The fixing plate is provided with pressing claws for pressing in position the thermal insulation material so as to press and prevent the thermal insulation material from getting released away from the fixing plate. And water passages are disposed in a manner to contact the pressing claws.
