Definitions

  • the combustion air duct and the exhaust duct are arranged one above the other and are connected by a wall box accommodated in a wall opening to a box cover provided on the outside of the room wall in one structural unit.
  • the exhaust gas duct is extended into the box space and the exhaust gas outlet opening formed in a base plate of the box cover is surrounded by frame walls of this box cover and a partition wall to the inlet area. so that the exit opening is largely shielded from the entrance opening even outside the room wall.
  • cover plate in front of the exhaust gas outlet opening, which covers the surface of the exhaust gas and thus prevents gusts of wind from entering the exhaust gas duct.
  • this cover plate is connected to the upper frame wall and at the bottom to the partition, while laterally free side openings, each of which has at least the area size of the exhaust gas outlet opening, are provided towards the side walls of the deflector frame.
  • the combustion air box room which is completely open to the outside, is spanned by a protective grille, particularly against stone chipping.
  • the actual inlet opening for the combustion air is set back in this box room and at least the size of the exhaust gas outlet opening.
  • the grid protective cage and the cover plate are arranged on the same level on the box cover which is formed as a component.
  • the inventive design of an outer wall box for a combustion air and exhaust gas duct ensures trouble-free operation of the connecting devices even if they are equipped with an atmospheric burner system.
  • the outer wall box shown comprises a wall box 8 inserted into a wall opening 4 of a room wall 3, which consists of a peripheral wall 12 and a box bottom 9.
  • An intermediate wall 13 divides this wall box into an upper exhaust gas chamber 5 and a lower combustion air chamber 6.
  • the exhaust and combustion air connection openings 10 and 11 are provided.
  • the wall box is closed by a base plate 14 which is attached to the wall of the room.
  • an outlet opening 15 for the exhaust gases is formed in this base plate.
  • a nozzle rim 16 of a few, for example five to ten millimeters in height, surrounds this outlet opening.
  • In the area of the combustion air chamber 6 there is an inlet opening 20 which is also provided with a nozzle edge 21.
  • the exhaust gas outlet opening 15 is markedly larger than the combustion air inlet opening 20.
  • a diameter ratio of 1.09 to 1.4 to 1 has been found to be advantageous.
  • the enlarged outlet opening 15 not only enables easier exhaust gas discharge due to its large passage area, but also contributes to external wind influences on the outlet opening to prevent backflow in the exhaust gas duct due to greater possibilities for the exhaust gas flow to escape.
  • Holes 23 are used to fasten the base plate to the wall of the room.
  • a box cover 25 can be placed on the base plate and inserted via the eyelets 45 aligned with holes 23 by fastening screws (not shown).
  • the box cover is surrounded by a deflector frame 26, which is formed by an upper frame wall 27, the side walls 28 and a partition wall 29.
  • the side walls 28 have a sloping edge 30 sloping in the direction of the partition wall.
  • the beveling of the side walls expediently begins only after a corner projection 31.
  • the beveling of the side walls is between 3 ° and 6 °, advantageously 4 °, compared to the base plate.
  • the partition wall 29 connecting the lower ends of the tapered side walls is therefore noticeably lower than the upper frame wall 27 and separates the exhaust gas area from the combustion air area outside the base plate.
  • a narrow gap 32 in this partition serves to equalize the pressure between these two areas.
  • a cover plate 33 is provided which completely covers the outlet opening and which merges into the upper frame wall 27 at the top and into the partition wall 29 below. In this way, the cover plate also takes an inclined position. As a result, a negative pressure is generated by a gust of wind, regardless of the wind direction, in the exhaust gas outlet area between the cover plate 33 and the side walls 28 to the outlet opening 15, so that the flow through the connected device is additionally supported. It has proven to be expedient here if the cover plate lifts out in the direction of the upper frame wall 27 slightly above the connecting plane through the inclined edges 30.
  • the base plate is spanned in the area of the combustion air inlet by a grille protective basket 39, which is connected to the partition by struts 38 stands and rests on the base plate by means of a web frame 40.
  • a cover housing 42 for a condensate drain pipe (not visible).
  • the box cover 25 designed as a molded part expediently also has a circumferential fold 44 through which the box cover can be placed on the base plate in a secured and fixed arrangement.
