The air supply port 10 of the instrument main body 9 is communicated with the air supply window 17 through a duct 19 made up of 9b, so that air supply and exhaust are performed on the passage 2 side.

(Function) To explain its operation, when the gas appliance 13 is operated, predetermined air supply and exhaust is performed between the gas appliance 13 and the passage 2 side. That is, the air supply port 10 and the exhaust port 11 on the side surface of the appliance main body 9 accommodated in the space 3, which cannot be opened directly to the passage 2 side, are connected to the duct portion 19a on the gas appliance 13 side. The air supply window 17 or the exhaust window 19 provided in the cover body 16 is communicated with the air supply window 17 or exhaust window 19 provided in the cover body 16 through the duct 19, which is composed of a duct portion 19b on the side of the cover body 16 where the air supply cannot be opened directly to the passage 2 side. The port 10 or the exhaust port 11 can be opened to communicate with the passage 2 side, and both supply and exhaust can be performed on the passage 2 side.

In other words, there is no possibility that the exhaust air will be directly guided into the piping space 3 and fill the space 3, or that the supply air will be further guided from within the space 3 and cause an air supply failure.

(Effects of the invention) According to the present invention, even if a gas appliance installed in a recess such as a recessed piping space on a wall has an air supply/exhaust opening on a surface other than the front surface, the opening can be connected to the front surface of the recess through a duct. It can communicate with the supply/exhaust window formed in the lid that covers the lid, and the supply and exhaust can be performed between the outside of the lid and the inconvenience of having to do this inside the piping space, making it possible to use ordinary gas appliances. It can be easily installed in recesses such as piping spaces,
Moreover, since the duct is divided into the duct part on the gas appliance side and the duct part on the lid side, which can be freely inserted and removed in the front-rear direction, when the lid is removed forward, the duct part on the lid side is connected to the gas appliance side. The lid can be removed from the duct part of the lid, so it does not interfere with the work of attaching and removing the lid.In fact, when the lid is attached, the lid can be held in place by fitting both duct parts, and when screwing the lid, the lid can be held in place. It is not necessary to hold the body with your hands, which improves the workability of attaching the lid.Furthermore, since the duct is not exposed on the front of the lid, it looks good, and the distance between the gas appliance and the lid can be reduced. Even if there is variation, the variation is absorbed in the fitting portion of both duct parts, and there is an effect that the window of the lid body and the opening of the gas appliance can be reliably communicated through the duct.
