摘要： A method of installing an exhaust tube is implemented by inserting an exhaust tube into an exhaust pipe that leads from inside of a building to outside thereof. A support portion of an insertion jig is introduced into a through hole from a side of one end portion of the exhaust tube, and a projection of the support portion is engaged with a recess of the exhaust tube, so that the insertion jig is fixed to the exhaust tube. An end of the exhaust tube on the side of the one end portion having the insertion jig fixed thereto is inserted into the exhaust pipe, and the exhaust tube is pushed from inside of the building to outside thereof.

摘要： A conduit made of a synthetic resin, having an inner surface and an outer surface, having concave portions and convex portions alternately and continuously provided in the length direction. The conduit is bendable. The conduit includes outer wall parts extending with a first width in the length direction; inner wall parts positioned radially inside relative to the outer wall parts and extending with a second width in the length direction; and side wall parts joining the outer wall parts and the inner wall parts so that the outer wall parts and the inner wall parts are alternately and continuously provided in the length direction. The outer surfaces of the outer wall parts each have, at both ends in the length direction, protruding parts, which protrude in the radial direction.

摘要： A water heater is provided that can suppress backflow (entry) of drainage water into a fan from downstream of the fan in a path of a flow of combustion gas. The fan includes a fan case, an impeller housed within the fan case, a drive source attached to the fan case so as to drive the impeller, and a rotation shaft connecting the impeller and the drive source. An exhaust connection portion has a connection portion case and is provided with an exhaust port for emitting combustion gas delivered from the fan to outside of the water heater. The exhaust connection portion also has a drainage water discharge portion for discharging drainage water accumulated downstream of the fan in the path of the flow of combustion gas.
