  • a common, flat, elastic pressure plate is provided in one part for sealing the bores for the passage of the tube of the thermoelectric pilot light fuse, the gas fitting and, if appropriate, further tubes, which is pressed onto the locking plate by means of a pressure frame.
  • the invention can also be characterized in that the upper shoulder of the nozzle holder tube at the upper end of the gas fitting for holding the pilot burner tube touches the lower surface of the locking plate or is in its immediate vicinity.
  • the gas-heated water boiler and instantaneous water heater according to the invention with a closed combustion chamber without an internal jacket has the following main advantages:
  • the separate box previously used to form the closed combustion chamber can be dispensed with, as a result the amount of material and working time required for production are significantly reduced;
  • the weight of the water boiler or instantaneous water heater (heating geiser) is also reduced by 4 to 5 kg.
  • the assembly or disassembly can be carried out in a few simple steps, which is why the working time required for checking, adjusting and replacing components is shorter.
  • the seal can not be damaged, the seal once used can be left unchanged for a very long time.
  • the construction is simple, not susceptible to faults and can be produced inexpensively.
  • a rear wall 1 shown in FIG. 1 in a front view is made from sheet metal material.
  • a recess 2 is used to carry out the wall duct, not shown, for supplying the combustion air and the duct part for the discharge of the combustion products.
  • the sheet material of the rear wall 1 is folded over vertically on both sides and above, and the folded parts are fastened to one another at their corners to form side sheets 3.
  • the outer parts of the side panels 3 are folded inwards parallel to the plane of the rear wall 1, and these parts form flanges 4.
  • a recess of a larger size is provided for the passage of pipelines, not shown, the edges of the recess being turned up on all three sides are.
  • These folded parts form a flange 5, the purpose of which is to prevent damage to the rear wall during assembly.
  • a lower locking plate 6 is fastened to the rear wall 1, approximately between the lower and the middle third, perpendicular to the rear wall, advantageously by welding.
  • the locking plate 6, as shown in Fig. 3, has a wedge shape and has on its edges flanges, the size of which corresponds to that of the flanges 4.
  • the rear wall 1 can be covered with a front jacket 7, which essentially consists of a front plate 8, side plates 9 connected to the two vertical edges and a second locking plate 10 fastened inside, advantageously by welding.
  • a front jacket 7 which essentially consists of a front plate 8, side plates 9 connected to the two vertical edges and a second locking plate 10 fastened inside, advantageously by welding.
  • the recess is continued at the lower part of the rear wall 1.
  • a flange 5 is also arranged around this part of the recess.
  • connection between the rear wall 1 and the front jacket 7 is designed such that the front jacket 7 can be removed and removed in a few simple steps from the rear wall 1 attached to a house wall or the like.
  • the connection is in 2 and 7.
  • the upper side plates 3 of the rear wall 1 are each attached to the two side plates 9 via a hanging plate 11, for example by welding, a hanging eye 12 being cut out of the part protruding beyond the side plate 3 is bent downwards at an angle of close to 90 °.
  • slots 13 are formed in each of the side plates, in which the suspension eyes 12 can be hung.
  • the hanging eyes 12 and the slot 13 are designed so that in the complete state the hanging eye 12 covers the slot 13 practically gas-tight.
