開口している。 The combustion chamber 1 is housed in a casing consisting of a front-open box-shaped rear case 16 that can be separated into two parts, front and rear, and a flat box-shaped front case 17 that overlaps the opening. The combustion chamber 1 is fixed to the rear case 16, and the passage formed between the side wall of the rear case 16 and the side wall of the combustion chamber 1 serves as an air supply passage 31 within the appliance. An air supply opening 32 that is concentric with the opening 13 is opened in the upper part of the air supply passage 31 facing the opening 13 .
従つて、後ケース１６を壁面Ｗに固定すると、
器具全体が壁面Ｗに取付けられることとなる。 Therefore, when the rear case 16 is fixed to the wall surface W,
The entire fixture will be attached to the wall surface W.

が連通することとなる。 Next, the structure of the air supply/exhaust pipe is such that the exhaust pipe 2 and the air supply pipe 3 loosely fitted concentrically with the exhaust pipe 2 are connected as a unit to the air supply/exhaust opening of the appliance. As shown in FIG. 7, a sleeve S was inserted into the through hole formed in the wall surface W, and the combination of the exhaust pipe 2 and the air supply pipe 3 was inserted into the sleeve S and attached to the rear case 16. Bracket 5
As a result, the instrument is installed in a state where the sleeve S is properly positioned in relation to the opening 13 and the air supply opening 32. Thereafter, the flange portion at the upstream end of the exhaust pipe 2 is fixed to the periphery of the opening 13, and the flange portion at the downstream end of the air supply pipe 3 is pressed into contact with the opening periphery of the air supply opening 32. The gap between the combustion chamber 1 and the exhaust pipe 2 communicates with the air supply passage 31, and the inside of the combustion chamber 1 and the inside of the exhaust pipe 2 communicate with each other, so that an air supply and exhaust circuit via the combustion chamber 1 communicates with each other.
ところが、この従来のものでは、器具設置の際

る。 This is because, in the above conventional system, when installing the unit consisting of the exhaust pipe 2 and the air supply pipe 3, the front case 17 is removed from the rear case 16, and the rear case 16 is installed on the wall surface W, and at the same time, the cover plate 14 is attached. This is because the flange portion of the exhaust pipe 2 is screwed to the periphery of the opening 13 using thumbscrews, and after the connection of the unit is completed, the cover plate 1 is removed.
This is because if the front case 17 is attached with the front case 17 forgotten to be closed, a part of the exhaust exhaust circuit from the combustion chamber 1 to the exhaust pipe 2 will be opened to the indoor side through the working opening 15. Furthermore, a similar situation may occur if the cover plate 14 is incompletely attached.

前記作業が容易なものとなる。 Next, when the peripheral edge of the air supply opening 32 and the flange portion F are screwed together via a gasket using wing screws N, N, the first intake pipe 3a and the air supply box 33 are airtightly connected. After the connection is completed, the cover plate 14
When the front case 17 is attached to the rear case 16, the installation of the instrument is completed. Here, as shown in FIG. 5, the working opening 15 is set large enough to allow tightening of the wing screws N, N.
This makes the work easier.
