PROBLEM TO BE SOLVED: To achieve the safe use by preventing direct touching on the high temperature part of the inspection window. SOLUTION: The inspection window 40 is provided with an outer window glass 41 and an inner window glass 42 both made up of a roughly rectangular transparent fireproof glass larger than the upper opening 31 of the grill and an aluminum die cast frame body 43 covering the outer circumference of the outer window glass 41 from above. In this manner, the inspection window 40 is made in a double structure of the outer and inner window glasses 41 and 42. In other words, the inner window glass 42 is placed inner than the surface of a front panel 20 and is covered with the outer window glass 41. This keeps the users from directly touching the inner window glass 42 the highest in temperature because of the direct contact with the combustion exhaust to prevent burns thereby achieving the safe use.
