Therefore, if necessary, either one more or less wide gap between the plaster surface and the Heater to be accepted, or the distance dimensions of the The mounting plate must be matched to the plaster thickness. This problem does not occur if the Guiding approaches on the mounting plate by water-carrying connection pieces themselves are formed, the when sliding the heater telescopically in or over appropriately trained connection elements of the heater to grab. The water-bearing connections between The mounting plate and heater can be expediently fitted with O-rings be sealed on the connecting piece of the Mounting plate or the heater are clamped and on come into contact with the inner walls of the counter sockets.

Die Gasverbindung zwischen den Teilen kann zweckmäßig durch eine Schneidringverschraubung hergestellt sein. Es wird vorgeschlagen, daß die geräteseitigen Anschlußstutzen der Montageplatte in Achsrichtung so bemessen und auf die korrespondierenden Anschlüsse des Heizgerätes abgestimmt sind, daß erst die Anschlußelemente der Gasleitung und erst danach die Anschlußelemente der Wasserführungen miteinander in Eingriff kommen.The gas connection between the parts can be conveniently by a cutting ring fitting can be made. It will proposed that the device-side connecting piece of Dimension the mounting plate in the axial direction and on the Corresponding connections of the heater matched are that only the connecting elements of the gas line and only then the connecting elements of the water channels with each other come into engagement.

Eine einfache und fertigungsgerechte Ausführung der Montageplatte ergibt sich, wenn ihr tragendes Bauelement ein einstückig geformtes Blechteil ist, das einen die Anschlüsse und gegebenenfalls weitere Funktionselemente tragenden mittleren Stegteil und zwei einstückig damit verbundene, mit den Auflageflächen und Gegenhaltern versehene, an der Wand befestigbare Konsolteile hat, die das Stegteil im Abstand von der Wand halten.A simple and production-oriented execution of the Mounting plate arises when its load-bearing component is a one-piece molded sheet metal part, the one the connections and possibly carrying further functional elements middle web part and two integrally connected, with the support surfaces and counter supports on the wall has attachable bracket parts that the web part at a distance hold away from the wall.

Bei der Montage des Heizgerätes wird dieses von vorn auf die Auflageflächen 26 der Konsolteile 12, 14 aufgeschoben, wobei diese das Heizgerät seitlich führen und nach unten abstützen. Die Auflageflächen 26 und die Schlitze 34 sind so lang bemessen, daß das Heizgerät bereits kippsicher auf der Montageplatte aufliegt, wenn die Anschlüsse für Wasser und Gas an der Montageplatte und am Heizgerät aneinander herangeführt sind. Die beiderseitigen Anschlüsse sind nun so bemessen, daß zuerst das Gasrohr am Heizgerät in die Gasarmatur 70 eintritt und sich erst danach die wasserführenden Anschlußstutzen 36, 38, 40, 42 der Montageplatte teleskopartig und abgedichtet in die korrespondierenden Anschlußelemente des Heizgerätes schieben. Dabei ist der Installateur vom Gewicht des Heizgerätes entlastet, so daß auch eine Einmannmontage möglich ist. Das Heizgerät kann bis zur Anlage an der Putzoberfläche der Wand vorgeschoben werden, wodurch unterschiedliche Putzstärken, beispielsweise bis zu 35 mm ausgeglichen werden. Durch die Anordnung der Dreiwegeventile ist eine getrennte Entleerung von Anlage und Heizgerät möglich.When installing the heater, this is from the front on the Support surfaces 26 of the console parts 12, 14 pushed on these guide the heater sideways and down support. The contact surfaces 26 and the slots 34 are so long dimensioned that the heater is already tilt-proof on the Mounting plate rests when the connections for water and Gas together on the mounting plate and on the heater are introduced. The connections on both sides are now like this dimension that first the gas pipe on the heater into the Gas fitting 70 occurs and only then the water-carrying connection piece 36, 38, 40, 42 of Mounting plate telescopic and sealed in the corresponding connection elements of the heater slide. The installer is by the weight of the Relieved heater, so that also a one-man installation is possible. The heater can be connected to the system Plaster surface of the wall are pushed forward, whereby different plaster thicknesses, for example up to 35 mm be balanced. Due to the arrangement of the three-way valves is a separate emptying of the system and the heater possible.
