Abstract
A method of installing an exhaust tube is implemented by inserting an exhaust tube into an exhaust pipe that leads from the inside of a building to the outside thereof. Utilizing an already-placed exhaust pipe, a new exhaust tube is inserted into this exhaust pipe. The exhaust tube is installed according to a procedure of: performing, on the inside of the building, an operation of inserting a new exhaust tube into the already-placed exhaust pipe; performing, on the outside of the building, an operation of fixing the inserted exhaust tube to the exhaust pipe; and performing, on the inside of the building, an operation of connecting the fixed exhaust tube to an exhaust vent of a combustion apparatus.
Claims10
A method of installing an exhaust tube through which combustion gas produced in a combustion apparatus placed on an inside of a building is emitted to an outside of said building, said method comprising:
- a first inside step including the step of, by an operation on the inside of said building, inserting, from the inside of said building toward the outside thereof, an exhaust tube into an exhaust pipe already placed and leading from the inside of said building to the outside thereof;
- an outside step including the step of, by an operation on the outside of said building, fitting an exhaust adapter having an annular shape into a gap between an outer circumferential surface of said exhaust tube and an inner circumferential surface of said exhaust pipe to close said gap and fix said exhaust tube to said exhaust pipe;
- and
- a second inside step including the step of, by an operation on the inside of said building, connecting a rear end portion of said exhaust tube and an exhaust vent of said combustion apparatus,
- said first inside step, said outside step and said second inside step being performed in this order, wherein
- said first inside step further includes, after the step of inserting said exhaust tube into said exhaust pipe, the step of temporarily fixing said exhaust tube to said exhaust pipe by a fixing member so as to prevent said exhaust tube from slipping down by a self weight.
A method of installing an exhaust tube through which combustion gas produced in a combustion apparatus placed on an inside of a building is emitted to an outside of said building, said method comprising:
- a first inside step including the step of, by an operation on the inside of said building, inserting, from the inside of said building toward the outside thereof, an exhaust tube into an exhaust pipe already placed and leading from the inside of said building to the outside thereof;
- an outside step including the step of, by an operation on the outside of said building, fitting an exhaust adapter having an annular shape into a gap between an outer circumferential surface of said exhaust tube and an inner circumferential surface of said exhaust pipe to close said gap and fix said exhaust tube to said exhaust pipe;
- and
- a second inside step including the step of, by an operation on the inside of said building, connecting a rear end portion of said exhaust tube and an exhaust vent of said combustion apparatus,
- said first inside step, said outside step and said second inside step being performed in this order, wherein
- before said first inside step, an outside end portion of said exhaust pipe located on the outside of said building is provided with an exhaust terminal including at least an exhaust port through which said combustion gas is emitted to outside, and a ceiling wall, and
- said outside step further includes the steps of:
- removing said exhaust terminal from said exhaust pipe before the step of fixing said exhaust tube;
- and
- attaching said exhaust terminal to said outside end portion of said exhaust pipe after the step of fixing said exhaust tube.
A method of installing an exhaust tube through which combustion gas produced in a combustion apparatus placed on an inside of a building is emitted to an outside of said building, said method comprising:
- a first inside step including the step of, by an operation on the inside of said building, inserting, from the inside of said building toward the outside thereof, an exhaust tube into an exhaust pipe already placed and leading from the inside of said building to the outside thereof;
- an outside step including the step of, by an operation on the outside of said building, fitting an exhaust adapter having an annular shape into a gap between an outer circumferential surface of said exhaust tube and an inner circumferential surface of said exhaust pipe to close said gap and fix said exhaust tube to said exhaust pipe;
- and
- a second inside step including the step of, by an operation on the inside of said building, connecting a rear end portion of said exhaust tube and an exhaust vent of said combustion apparatus,
- said first inside step, said outside step and said second inside step being performed in this order, wherein
- before said first inside step, an outside end portion of said exhaust pipe located on the outside of said building is provided with an exhaust terminal including at least an exhaust port through which said combustion gas is emitted to outside, and a ceiling wall, and
- said outside step further includes, after the step of fixing said exhaust tube, the step of attaching, to said tip end portion of said exhaust tube, an exhaust straightening member including a circumferential wall portion having a cylindrical shape and a plurality of openings through which said combustion gas flows out toward said exhaust port of said exhaust terminal, and a cover portion that closes one end of said circumferential wall portion.
A method of installing an exhaust tube through which combustion gas produced in a combustion apparatus placed on an inside of a building is emitted to an outside of said building, said method comprising:
- a first inside step including the step of, by an operation on the inside of said building, inserting, from the inside of said building toward the outside thereof, an exhaust tube into an exhaust pipe already placed and leading from the inside of said building to the outside thereof;
- an outside step including the step of, by an operation on the outside of said building, fitting an exhaust adapter having an annular shape into a gap between an outer circumferential surface of said exhaust tube and an inner circumferential surface of said exhaust pipe to close said gap and fix said exhaust tube to said exhaust pipe;
- and
- a second inside step including the step of, by an operation on the inside of said building, connecting a rear end portion of said exhaust tube and an exhaust vent of said combustion apparatus,
- said first inside step, said outside step and said second inside step being performed in this order, wherein
- said second inside step further includes the step of attaching a protection tube for protecting at least a part of said exhaust tube extending from said exhaust pipe to said combustion apparatus.
A method of installing an exhaust tube through which combustion gas produced in a combustion apparatus placed on an inside of a building is emitted to an outside of said building, said method comprising:
- a first inside step including the step of, by an operation on the inside of said building, inserting, from the inside of said building toward the outside thereof, an exhaust tube into an exhaust pipe already placed and leading from the inside of said building to the outside thereof;
- an outside step including the step of, by an operation on the outside of said building, fitting an exhaust adapter having an annular shape into a gap between an outer circumferential surface of said exhaust tube and an inner circumferential surface of said exhaust pipe to close said gap and fix said exhaust tube to said exhaust pipe;
