Definitions

  • the invention relates to a horizontal roof or exterior wall passage having substantially concentric pipes.
  • the invention further relates to a connection portion for a horizontal roof or exterior wall passage.
  • Concentric exterior wall passages are provided with an inner pipe for forming a first passage for the discharge of flue gasses and an outer pipe that surrounds the inner pipe for forming a substantially annular passage between the inner pipe and the outer pipe for the supply of air.
  • the first passage has to be placed at a slope for discharging condense water to the appliance.
  • a slope can be realised by means of an inclined set-up of the inner pipe with respect to the outer pipe, wherein the outer pipe is usually placed horizontally in the wall.
  • the inner pipe is placed centrically at the side facing the boiler, the inner side, for a good connection to the boiler pipe.
  • the inner pipe at the outside of the exterior wall passage is placed eccentrically with respect to the outer pipe.
  • a drawback of the eccentric placement of the inner pipe at the outside is that at the inflow side of the annular passage a significant difference of pressure may arise in case there is question of a difference pressure plane between the inner pipe and the outer pipe, for instance due to a fall wind or a rise wind.
  • a horizontal roof or exterior wall passage comprising a pipe assembly having an inner pipe for forming a first passage and an outer pipe surrounding the inner pipe for forming a substantially annular passage between the inner pipe and the outer pipe, wherein the inner pipe at both ends of the outer pipe is placed centrically within the outer pipe, wherein a centre line of the inner pipe and a centre line of the outer pipe diverge from each other from a first end towards a second end of the outer pipe, and wherein the pipe assembly comprises adapting means for bringing the centre lines of the inner pipe and the outer pipe towards each other at the second end.
  • the centre lines of the inner pipe and the outer pipe coincide or intersect at the first end of the outer pipe, as a result of which the inner pipe is centrically placed within the outer pipe at that location. Furthermore because from the first end of the outer pipe the centre line of the inner pipe diverges with respect to the centre line of the outer pipe, the inner pipe is placed inclined with respect to the outer pipe at that location. This inclined position ensures the desired slope of the inner pipe in a substantially horizontally placed outer pipe of the horizontal roof or exterior wall passage.
  • the adapting means of the pipe assembly ensure a change in direction of at least one of the said centre lines so that the centre lines of the inner pipe and the outer pipe coincide or intersect at the second end of the outer pipe.
  • the outer pipe comprises a first and a second outer pipe portion having first and second centre lines, respectively, wherein the first centre line of the first outer pipe portion and the centre line of the inner pipe, at least the part of the inner pipe that is surrounded by the first outer pipe portion, are substantially straight and intersect at the first end of the outer pipe, and wherein the second outer pipe portion comprises adapting means for at that location at least partially bringing the second centre line of the second outer pipe portion out of line with the first centre line of the first outer pipe portion, wherein the centre lines of the inner pipe and the second outer pipe portion intersect at the second end of the outer pipe.
  • the outer pipe particularly the second outer pipe portion, is provided with adapting means.
  • the adapting means of the second pipe portion ensure, at least partially, the correct spatial placement of the inner pipe with respect to the outer pipe.
  • the adapting means of the second outer pipe portion comprise a twin elbow.
  • the centre line of the second pipe portion is saltatorily shifted or tilted with respect to the first outer pipe portion. Because of the twin elbow the centre lines of the outer pipe portions are placed staggered with respect to each other or receded.
  • the adapting means of the second outer pipe portion comprise a reducer, preferably an eccentric reducer.
  • This reducer forms a further means for more or less smoothly shifting the centre line of the second outer pipe portion with respect to the first outer pipe portion.
  • the inner pipe comprises a first and a second inner pipe portion, wherein a centre line of the first inner pipe portion and a centre line of the outer pipe, at least the portion of the outer pipe that surrounds the first inner pipe portion, are substantially straight and intersect at the first end of the outer pipe, and wherein the second inner pipe portion comprises adapting means for at that location at least partially bringing the centre line of the second inner pipe portion out of line with the centre line of the first inner pipe portion, wherein the centre lines of the outer pipe and the second inner pipe portion intersect at the second end of the outer pipe.
  • the inner pipe particularly the second inner pipe portion, is provided with adapting means.
  • the adapting means of the second inner pipe portion ensure, at least partially, the correct spatial placement of the inner pipe with respect to the outer pipe.
  • both the inner pipe and the outer pipe may comprise a first and second pipe portion.
  • Both the second outer pipe portion and the second inner pipe portion may comprise adapting means here.
  • Preferably the first and second inner pipe portion are surrounded by the first and second outer pipe portion, respectively.
  • the adapting means of the first inner pipe portion comprise a twin elbow.
  • the adapting means for the first connection portion comprise a reducer, preferably an eccentric reducer.
  • the adapting means of the second outer pipe portion and of the second inner pipe portion comprise a bend.
  • the second end of the pipe assembly can be placed at an angle to the first end of the pipe assembly.
  • the second outer pipe portion comprises a substantially squared bend.
  • the boiler can easily be connected to a roof or exterior wall passage that is placed immediately above or adjacent to the boiler.
  • first outer pipe portion and the second outer pipe portion are formed as separate pipe members, wherein the first and/or the second outer pipe portion comprise coupling means for coupling the first and second outer pipe portion to each other.
  • first and second outer pipe portions are logistically advantageous: the available straight outer pipes of the known concentric wall or exterior wall passages can be used for the horizontal roof or exterior wall passage according to the invention, as the first outer pipe portion.
  • the second outer pipe portion at a side oriented towards the first outer pipe portion comprises a pipe member that can be slid fittingly in or around the first outer pipe portion.
  • This pipe member offers a simple coupling means.
  • the length of the outer pipe can be adjusted by means of this pipe member to the thickness of the exterior wall or to the thickness of the roof structure.
  • first inner pipe portion and the second inner pipe portion may also be formed as separate pipe members, wherein the first and/or the second inner pipe portion comprise coupling means for coupling the first and second inner pipe portion to each other.
