Abstract:
To provide a combustion apparatus capable of efficiently guiding air from a fan to a combustion casing while suppressing an increase in production cost.SOLUTION: A relay casing 14 of a water heater 1 includes: a top plate 14a having a first opening 14g; a first side plate 14c having a second opening 14h; and a fourth side plate 14f crossing the top plate 14a and the first side plate 14c. A width of the first opening 14g in a third direction D3 is larger than a width of the second opening 14h. The fourth side plate 14f is inclined so that a width of an inner space of the relay casing 14 in the third direction D3 increases as it approaches the second opening 14h in an axial direction of the first opening 14g.SELECTED DRAWING: Figure 9
