The control unit 60 is disposed inside a service window 10b provided on one side of the main body 10, and controls the drive of the combustor 20, oil pump 40, combustion blower 50, and the like.

The heat shielding chamber 70 is a box-shaped chamber made of a shielding plate 70a and the like for shielding heat generated from the combustor 20, and is located at the upper part of the main body 10 on the side opposite to the position of the exhaust pipe attachment port 31. It is provided. Further, a plurality of intake ports 71 are provided on the back side of the heat shielding chamber 70.
and communicates with the outside of the main body 10 via the intake port. Further, the heat shielding chamber 70 communicates with an exhaust passage 73 provided on the upper front side of the main body 10 via an exhaust port 72 provided on one side near the front side.
3 communicates with the outside of the main body 10 via an exhaust port 74 provided at the top of the main body 10. Furthermore, heat shielding plates 75 and 76 are disposed with a predetermined gap sufficient to allow air to flow from the inside surface of the main body 10 of the heat shielding chamber 70. A plurality of slits 75a are provided in the heat shielding plate 75, which is arranged parallel to the lower surface of the heat shielding chamber 70, and the heat shielding plate 75 is provided with a plurality of slits 75a.
A plurality of slits 76a are provided in the upper part of the heat shielding plate 76, which is arranged parallel to the side surface of one end, and the heat shielding chamber 70 and each of the heat shielding plates 75, 7 are provided with a plurality of slits 76a.

In addition, when performing a power outage combustion operation during a power outage, that is, an operation in which the combustion amount of the combustor 20 is minimized,
Although the cooling blower 80 is stopped, the conduction and radiation of heat to the operating section 90 is prevented by the heat shielding plate 75,
76 and a heat shield chamber 70. Also,
The rising air current generated inside the main body 10 flows into the air flow passage 77 through the slit 75a, and flows into the main body 10 through the slit 76a and the communication port 78.
By flowing out to the outside, the heat shielding chamber 70 is cooled. As a result, the temperature rise in the operating section 90 and the upper front surface of the main body is reduced.

Note that the cooling blower may be a small one having sufficient performance to cool the inside of the heat shielding chamber 70 and the operation section 90.
