Claims

[Claims for Utility Model Registration] 1. In a hot-air heater that discharges combustion gas heat-exchanged in a heat exchanger through an exhaust nozzle, the exhaust pipe is provided with a drain discharge pipe and a detection pipe for a wind pressure switch. A hot air heater characterized in that a single pipe body that also serves as a pipe is arranged through the pipe body, and a thank-you pressure detection part and a drain part are respectively provided in the part of the pipe body located in the exhaust pipe. 2. A utility model registration request characterized in that holes are formed in the upper and lower parts of the pipe body located inside the exhaust pipe, and the upper hole is used as a pressure detection part and the lower part is used as a drain part. A hot air heater as described in Scope 1. 3. A long hole having a long axis in the vertical direction is bored in the lower part of the pipe body located inside the exhaust pipe, and the upper half of this long hole is used as the pressure detection part, and the lower half is used as the drain part. A hot air heater according to claim 1 of the utility model registration claim.
