Description

La présente invention à trait au domaine général de la fumisterie.
Elle concerne plus particulièrement un dispositif d'habillage pour un conduit assurant le raccordement entre un appareil de chauffage (type poêle ou cuisinière) et un conduit d'évacuation de fumée aboutissant à une cheminée ; elle concerne encore le procédé de mise en ouvre d'un tel dispositif d'habillage.The present invention relates to the general field of fumistery.
It relates more particularly to a cladding device for a conduit providing the connection between a heater (type stove or stove) and a smoke evacuation conduit leading to a chimney; it also relates to the method of implementing such a cladding device.

Les appareils de chauffage du genre poêle ou cuisinière génèrent des fumées qu'il est nécessaire de canaliser en vue de leur évacuation à l'extérieur de l'habitation équipée.
De manière classique, lors de la construction de l'habitation, un conduit d'évacuation de fumée peut être posé entre le plafond (ou le faux plafond) de la pièce dans laquelle l'appareil de chauffage est prévu, et une sortie extérieure, généralement une cheminée sortant de la toiture.
L'extrémité inférieure de ce conduit d'évacuation dépasse de quelques centimètres sous le niveau du plafond de la pièce équipée ; cette extrémité inférieure est destinée à être raccordée à l'appareil de chauffage par un conduit de raccordement adapté, apparent.
Comme décrit dans le document EP-1 795 804 , ce conduit de raccordement peut être revêtu d'un dispositif d'habillage formé d'une enveloppe extérieure, concentrique, ménageant un espace cylindrique ouvert en partie supérieure et en partie inférieure, au sein duquel l'air peut circuler.
Cet espace cylindrique ventilé, qui s'étend sur pratiquement toute la hauteur du conduit de raccordement, constitue une chambre d'isolation permettant d'abaisser sensiblement la température au niveau de la surface externe de l'enveloppe d'habillage.
Le conduit de raccordement « habillé » est ici constitué par emboitement de différentes parties préparées à l'avance, chaque partie étant formée d'un tronçon de conduit, proprement dit, assemblé avec un tronçon d'enveloppe externe.
Le pré-assemblage correspondant est réalisé au moyen d'organes de liaison en forme de couronnes-entretoises munies d'évidements pour permettre la circulation de l'air et d'une pluralité de pattes, régulièrement réparties, équipées d'orifices pour la solidarisation de l'ensemble au moyen de vis.
Mais l'assemblage en question est relativement complexe et il peut difficilement être réalisé sur le site.
Pour cette raison, en pratique, les différentes parties « habillées » de conduit sont préparées en usine. Il est donc difficile d'équiper d'un tel habillage un conduit de raccordement existant.
D'autre part, cet assemblage nécessite le perçage du conduit de raccordement pour la fixation des couronnes-entretoises.Heating appliances of the stove or stove type generate fumes that must be channeled for disposal outside the equipped dwelling.
In a conventional manner, during the construction of the dwelling, a smoke evacuation duct may be placed between the ceiling (or the false ceiling) of the room in which the heating apparatus is provided, and an external outlet, usually a chimney coming out of the roof.
The lower end of this exhaust duct protrudes a few centimeters below the level of the ceiling of the equipped room; this lower end is intended to be connected to the heater by a suitable, visible connection duct.
As described in the document EP-1 795 804 this connecting duct may be covered with a covering device consisting of an outer casing, concentric, providing a cylindrical space open at the top and bottom, in which the air can circulate.
This ventilated cylindrical space, which extends over substantially the entire height of the connecting pipe, is an insulation chamber for substantially lowering the temperature at the outer surface of the casing.
The "dressed" connection duct here consists of interlocking different parts prepared in advance, each part being formed of a pipe section, itself, assembled with an outer casing section.
The corresponding pre-assembly is achieved by means of connecting members in the form of spacer rings provided with recesses to allow the circulation of air and a plurality of legs, regularly distributed, equipped with orifices for the joining together of the assembly by means of screws.
But the assembly in question is relatively complex and it can hardly be done on the site.
For this reason, in practice, the different "dressed" parts of the duct are prepared in the factory. It is therefore difficult to equip such an enclosure with an existing connection conduit.
On the other hand, this assembly requires the drilling of the connecting duct for fixing the spacer rings.

Le document US-4 865 013 décrit de son côté un dispositif d'habillage pour conduit de fumée de structure relativement complexe, constitué de deux éléments télescopiques, l'un supérieur équipé d'une plaque de fixation, et l'autre inférieur comportant un collier venant en butée contre des oreilles fixées audit conduit de fumée.The document U.S. 4,865,013 describes on its side a device for smoke duct of relatively complex structure structure, consisting of two telescopic elements, one upper equipped with a fixing plate, and the other lower having a collar abutting against ears attached to said flue.

La présente invention à pour but de remédier à ces inconvénients en proposant un dispositif d'habillage de structure simple, qui peut être très facilement associé tant à un conduit de raccordement existant, qu'à un tel conduit au moment de la pose de l'appareil de chauffage.The present invention aims to remedy these disadvantages by proposing a simple structure dressing device, which can be very easily associated both to an existing connecting conduit, to such a conduit at the time of installation of the heating appliance.

Pour cela, le dispositif d'habillage conforme à l'invention comprend une enveloppe constituée de deux éléments télescopiques, l'un inférieur et l'autre supérieur. En outre, les moyens de solidarisation entre cette enveloppe et le conduit de raccordement consistent, d'une part,

  • en un premier collier apte à venir se fixer par serrage sur une zone de la partie inférieure dudit conduit de raccordement, lequel premier collier de serrage est muni de moyens de centrage destinés à coopérer avec la face interne de l'élément inférieur de ladite enveloppe et, d'autre part
  • en un second collier apte à venir se fixer par serrage sur une zone de la partie supérieure dudit conduit de raccordement, lequel second collier de serrage est muni de moyens de centrage destinés à coopérer avec la face interne de l'élément supérieur de ladite enveloppe cylindrique.
De plus, le dispositif d'habillage en question comporte des moyens pour solidariser de manière amovible ledit élément supérieur d'enveloppe avec ledit second collier de serrage.For this, the dressing device according to the invention comprises an envelope consisting of two telescopic elements, one lower and the other upper. In addition, the securing means between this casing and the connection duct consist, on the one hand,
  • in a first collar adapted to be fixed by clamping on an area of the lower part of said connecting duct, which first clamping collar is provided with centering means intended to cooperate with the inner face of the lower element of said envelope and , on the other hand
  • in a second collar adapted to be fixed by clamping on an area of the upper part of said connecting pipe, which second clamping collar is provided with centering means intended to cooperate with the inner face of the upper element of said cylindrical envelope .
In addition, the covering device in question comprises means for releasably securing said upper shell member with said second clamp.

Selon une forme de réalisation particulière, les moyens pour solidariser de manière amovible l'élément supérieur d'enveloppe avec le second collier de serrage consistent en au moins un écrou solidaire dudit collier, associé à une vis de fixation passant au travers d'un orifice ménagé dans la partie supérieure dudit élément supérieur d'enveloppe.According to a particular embodiment, the means for releasably securing the upper casing element with the second clamping collar consist of at least one integral nut of said collar, associated with a fastening screw passing through an orifice formed in the upper part of said upper shell element.

De préférence, la bordure inférieure de l'élément inférieur d'enveloppe comporte une ouverture qui s'étend sur une partie de sa circonférence (avantageusement sur un secteur angulaire compris entre le quart et la moitié de sa circonférence).
D'autre part, la bordure supérieure de l'élément supérieur d'enveloppe comporte également une ouverture qui s'étend sur une partie de sa circonférence (avantageusement aussi sur un secteur angulaire compris entre le quart et la moitié de sa circonférence).Preferably, the lower edge of the lower casing element has an opening that extends over a portion of its circumference (preferably on an angular sector between one quarter and one half of its circumference).
On the other hand, the upper edge of the upper casing member also has an opening which extends over a portion of its circumference (advantageously also on an angular sector between one quarter and one half of its circumference).

Selon encore une autre particularité, la zone inférieure de la face interne de l'élément inférieur d'enveloppe comporte des moyens formant butée, agencés pour venir prendre appui contre les moyens de centrage du premier collier de serrage, de manière à assurer le positionnement dudit élément inférieur d'enveloppe.
Ces moyens formant butée sont avantageusement constitués par une virole rapportée, fixée contre la face interne de l'élément inférieur d'enveloppe, laquelle virole comporte - une partie supérieure dont le diamètre externe correspond, au jeu près, au diamètre interne dudit élément inférieur d'enveloppe, et - une partie inférieure, de diamètre plus petit, reliée à ladite première partie par un tronçon de réduction, la bordure inférieure de ladite partie inferieure de virole constituant ladite butée proprement dite.According to yet another feature, the lower zone of the inner face of the lower casing element comprises means forming a stop, arranged to come bear against the centering means of the first clamp, so as to ensure the positioning of said lower casing element.
These means forming a stop are advantageously constituted by an attached ferrule, fixed against the inner face of the lower casing element, which ferrule comprises an upper part whose external diameter corresponds, with the clearance, to the internal diameter of said lower element of the casing. envelope, and - a lower part, of smaller diameter, connected to said first part by a reduction section, the lower edge of said lower ferrule constituting said stopper itself.

L'invention concerne également un procédé de mise en oeuvre d'un tel dispositif d'habillage, ce procédé consistant :

  • à positionner la partie inférieure du conduit de raccordement sur l'appareil de chauffage,
  • à fixer le premier collier sur ladite partie inférieure du conduit de raccordement,
  • à mettre en place l'enveloppe du dispositif d'habillage, en position au moins partiellement rétractée, sur ladite partie inférieure du conduit de raccordement, avec son extrémité inférieure en appui contre ledit premier collier,
  • à terminer le montage dudit conduit de raccordement,
  • à fixer le second collier sur la partie supérieure dudit conduit de raccordement,
  • à déployer l'enveloppe dudit dispositif d'habillage télescopique pour que son élément supérieur atteigne ledit second collier, et
  • à solidariser ledit élément supérieur d'enveloppe avec ledit second collier.
The invention also relates to a method for implementing such a dressing device, this method consisting of:
  • positioning the lower part of the connection duct on the heater,
  • to fix the first collar on said lower part of the connection duct,
  • setting up the casing of the casing device, in at least partially retracted position, on said lower part of the connecting duct, with its lower end bearing against said first collar,
  • to complete the mounting of said connecting pipe,
  • attaching the second collar to the upper part of said connecting duct,
  • deploying the envelope of said telescopic wrapping device so that its upper member reaches said second collar, and
  • to secure said upper shell member with said second collar.

Pour obtenir un fonctionnement optimal, si elles sont présentes, les ouvertures inférieure et supérieure des deux éléments télescopiques sont orientées du coté de la face avant de l'appareil de chauffage.For optimal operation, if present, the lower and upper openings of the two telescopic elements are oriented on the side of the front face of the heater.

Le dispositif conforme à l'invention est adapté pour « habiller » un conduit vertical qui raccorde un appareil de chauffage et un conduit d'évacuation de fumée dont l'extrémité inférieure s'étend en saillie de quelques centimètres sous le plafond de la pièce équipée et dont l'extrémité supérieure aboutit à une cheminée.The device according to the invention is suitable for "dressing" a vertical duct which connects a heating device and a smoke evacuation duct whose lower end projects a few centimeters below the ceiling of the equipped room. and whose upper end leads to a chimney.

Comme illustrée sur les figures 1 à 7, le conduit de raccordement 1 en question est associé au dispositif d'habillage 2 qui comprend : une enveloppe cylindrique 3 constituée de deux éléments télescopique 4, 5, et deux colliers de fixation/entretoise : un premier inférieur 6 et un second supérieur 7.
Le conduit de raccordement 1, classique, est constitué de plusieurs tronçons cylindriques juxtaposés qui s'emboitent les uns dans les autres (par exemple deux tronçons). Son extrémité inférieure 1' est adaptée pour venir s'emboiter sur une sortie ménagée au niveau de l'appareil de chauffage et son extrémité supérieure 1 " est adaptée pour coopérer avec l'extrémité inférieure du conduit d'évacuation de fumée en légère saillie du plafond, vers le bas. La longueur totale du conduit 1 peut être comprise entre 800 et 3000 mm ; son diamètre peut être compris entre 80 et 200 mm.As illustrated on Figures 1 to 7 , the connection duct 1 in question is associated with the cladding device 2 which comprises: a cylindrical envelope 3 consisting of two telescopic elements 4, 5, and two clamps / spacer: a lower first 6 and a second upper 7.
The connecting pipe 1, conventional, consists of several cylindrical sections juxtaposed which fit into each other (for example two sections). Its lower end 1 'is adapted to fit on an outlet provided at the heater and its upper end 1 "is adapted to cooperate with the lower end of the smoke evacuation pipe slightly protruding from the The entire length of the duct 1 may be between 800 and 3000 mm and its diameter may be between 80 and 200 mm.

Les deux éléments télescopiques 4 et 5 formant l'enveloppe cylindrique 3 sont adaptés en longueur pour couvrir pratiquement totalement le conduit de raccordement 1, avec un recouvrement partiel entre eux. Chaque élément 4 et 5 peut ainsi avoir une longueur de 600 à 800 mm ; leur diamètre est adapté pour être supérieur à celui du conduit de raccordement 1, de manière à préserver un espace annulaire périphérique E, par exemple de 1 à 3 cm de large (préférentiellement voisin de 2 cm), lorsque l'enveloppe 3 recouvre le conduit 1.The two telescopic elements 4 and 5 forming the cylindrical envelope 3 are adapted in length to cover substantially completely the connecting pipe 1, with a partial overlap between them. Each element 4 and 5 can thus have a length of 600 to 800 mm; their diameter is adapted to be greater than that of the connecting duct 1, so as to preserve a peripheral annular space E , for example 1 to 3 cm wide (preferably close to 2 cm), when the casing 3 covers the duct 1.

Dans l'exemple de réalisation illustré, c'est l'élément supérieur 5 de l'enveloppe 3 qui coulisse dans l'élément inférieur 4. Ainsi, l'élément inférieur 4 (situé du côté de l'extrémité inférieure 1' du conduit de raccordement 1) a un diamètre interne qui correspond, au jeu près, au diamètre externe de l'élément supérieur 5 (situé du coté de l'extrémité supérieur 1 " du conduit 1).
Les deux éléments 4 et 5 de l'enveloppe 3 peuvent être réalisés en acier inoxydable, à partir d'une tôle dont l'épaisseur est de l'ordre de 0,4 à 1 mm.In the exemplary embodiment illustrated, it is the upper element 5 of the casing 3 which slides in the lower element 4. Thus, the lower element 4 (located on the side of the lower end 1 'of the duct 1) has an internal diameter which corresponds, with the clearance, to the outer diameter of the upper element 5 (located on the side of the upper end 1 "of the duct 1).
The two elements 4 and 5 of the casing 3 can be made of stainless steel, from a sheet whose thickness is of the order of 0.4 to 1 mm.

Sur les figures 1 et 2 on remarque que la bordure inférieure 4' de l'élément inférieur d'enveloppe 4 et que la bordure supérieure 5' de l'élément supérieur d'enveloppe 5 comportent chacune une ouverture, respectivement 8 et 9, en forme d'échancrure.
Ces échancrures 8 et 9 s'étendent sur un secteur angulaire de l'ordre de 180° et sur une hauteur de l'ordre de 2 à 3 cm.On the Figures 1 and 2 it is noted that the lower edge 4 'of the lower casing element 4 and the upper edge 5' of the upper casing element 5 each comprise an opening, 8 and 9 respectively, in the form of notch.
These notches 8 and 9 extend over an angular sector of the order of 180 ° and a height of about 2 to 3 cm.

Comme on peut le voir sur les figures 4 et 5, la zone inférieure de la face interne de l'élément inférieur d'enveloppe 4 reçoit une virole rapportée 10, solidarisée par soudage, dont la bordure inférieure 11 constitue un élément de butée interne destinée, comme expliqué plus loin, à venir prendre appui sur le collier de fixation inférieur 6, pour assurer le positionnement correct de l'enveloppe 3 sur le conduit 1.
Cette virole 10, par exemple réalisée en tôle d'acier inoxydable, comprend une partie supérieure cylindrique 12 et une partie inférieure cylindrique 13, reliées par un tronçon tronconique de raccordement 14.
Le diamètre externe de la partie supérieure 12 de la virole 10 correspond, au jeu près, au diamètre interne de l'élément inférieur d'enveloppe 4, pour assurer l'assemblage par soudage des deux éléments entre eux. D'autre part, la partie inférieure 13 de la virole 10 à un diamètre inférieur à celui de la partie supérieure 12, mais supérieur au diamètre externe du conduit 1. La différence de diamètre entre les parties supérieure 12 et inférieure 13 de la virole 10 peut être de l'ordre de 5 à 10 mm ; le tronçon de raccordement 14 assure la fonction de réducteur de diamètre.As can be seen on the Figures 4 and 5 , the lower zone of the inner face of the lower casing element 4 receives an attached ferrule 10, secured by welding, whose lower edge 11 constitutes an internal abutment element intended, as explained below, to come to bear on the lower fixing collar 6, to ensure the correct positioning of the casing 3 on the duct 1.
This ferrule 10, for example made of stainless steel sheet, comprises a cylindrical upper portion 12 and a cylindrical lower portion 13, connected by a frustoconical connecting portion 14.
The outer diameter of the upper portion 12 of the ferrule 10 corresponds, with the clearance, to the inner diameter of the lower casing element 4, to ensure the assembly by welding the two elements together. On the other hand, the lower portion 13 of the shell 10 to a diameter smaller than that of the upper portion 12, but greater than the outer diameter of the pipe 1. The difference in diameter between the upper 12 and lower 13 parts of the shell 10 can be of the order of 5 to 10 mm; the connection section 14 performs the function of diameter reducer.

La bordure inférieure 11 de la partie inférieure 13 de virole s'étend à l'intérieur de l'élément inférieur d'enveloppe 4, en deçà du niveau du fond de l'ouverture 8.The lower edge 11 of the lower part 13 of ferrule extends inside the lower element of envelope 4, below the level of the bottom of the opening 8.

Les deux éléments télescopiques 4 et 5 sont montés et maintenus sur le conduit de raccordement 1 au moyen des deux colliers rapportés 6 et 7 précités.The two telescopic elements 4 and 5 are mounted and held on the connecting pipe 1 by means of the two reported collars 6 and 7 above.

Le premier collier 6 consiste en un collier de serrage de type feuillard métallique équipé d'un système de serrage à vis/écrou 15. Ce collier 6 est monté sur le conduit de raccordement 1, au niveau d'une zone de la partie inférieure de ce conduit située à quelques centimètres au dessus de son extrémité inférieure.
Ce collier de serrage inférieur 6 comporte une structure de retour externe à l'équerre 16, dont l'extrémité extérieure constitue des moyens de centrage destinés à coopérer avec la face interne de l'enveloppe cylindrique 3, et en particulier de son élément inférieur 4.
D'autre part, la face supérieure de cette structure 16 forme une surface d'appui destinée à coopérer avec la bordure inférieure 11 de la virole 10, comme expliqué plus loin.The first collar 6 consists of a metal strip type clamping collar equipped with a screw / nut clamping system 15. This collar 6 is mounted on the connecting pipe 1, at a zone of the lower part of the this conduit located a few centimeters above its lower end.
This lower clamping collar 6 comprises a return structure external to the bracket 16, the outer end of which constitutes centering means intended to cooperate with the internal face of the cylindrical envelope 3, and in particular of its lower element 4. .
On the other hand, the upper face of this structure 16 forms a bearing surface intended to cooperate with the lower edge 11 of the shell 10, as explained below.

Cette structure de retour à l'équerre 16 peut être constituée d'une pluralité d'ailettes radiales, régulièrement espacées pour permettre la circulation de l'air dans l'espace annulaire E entre le conduit 1 et l'enveloppe 3.This square return structure 16 may consist of a plurality of radial fins, regularly spaced to allow the circulation of air in the annular space E between the duct 1 and the casing 3.

Le second collier 7 consiste aussi en un collier de serrage du type feuillard métallique équipé d'un système de serrage vis/écrou 17. Ce second collier 7 est monté sur le conduit de raccordement 1, au niveau d'une zone de la partie supérieure de ce conduit 1 située à quelques centimètres en dessous de son extrémité supérieure.
Ce collier de serrage supérieur 7 comporte une structure de retour externe à l'équerre 18 dont l'extrémité extérieure constitue des moyens de centrage destinés à coopérer avec la face interne de l'enveloppe cylindrique 3 et en particulier de son élément supérieur 5.
Ici encore, cette structure de retour à l'équerre 18 peut être constituée d'une pluralité d'ailettes radiales, régulièrement espacées, pour permettre la circulation de l'air dans l'espace E entre le conduit 1 et l'enveloppe 3.The second collar 7 also consists of a clamping collar of the metal strip type equipped with a screw / nut clamping system 17. This second collar 7 is mounted on the connecting pipe 1, at a zone of the upper part. this duct 1 located a few centimeters below its upper end.
This upper clamping collar 7 comprises a return structure external to the bracket 18, the outer end of which constitutes centering means intended to cooperate with the internal face of the cylindrical envelope 3 and in particular of its upper element 5.
Here again, this return-to-square structure 18 may consist of a plurality of radial fins, regularly spaced, to allow the circulation of air in the space E between the duct 1 and the casing 3.

D'autre part, le collier supérieur 7 comporte une structure d'écrou 19 (figures 6 et 7) apte à coopérer avec une vis 20 passant au travers d'un orifice 21 ménagé dans l'élément supérieur 5 de l'enveloppe 3, pour assurer la solidarisation entre ladite enveloppe 3 et le conduit de raccordement 1. Cet écrou 19 est avantageusement maintenu prisonnier dans une structure de réception adaptée ménagée sur le collier 7.On the other hand, the upper collar 7 comprises a nut structure 19 ( Figures 6 and 7 ) adapted to cooperate with a screw 20 passing through an orifice 21 formed in the upper member 5 of the casing 3, to ensure the connection between said casing 3 and the connecting duct 1. This nut 19 is advantageously maintained prisoner in a suitable receiving structure provided on the collar 7.

Dans une variante de réalisation, plusieurs systèmes vis/écrou 19,20 peuvent être ménagés sur la périphérie du collier 7.In an alternative embodiment, several screw / nut systems 19, 20 may be provided on the periphery of the collar 7.

L'installation du dispositif d'habillage ventilé 2 sur le conduit de raccordement 1 équipant un poêle à bois est illustré sur les figures 8 à 12.
Sur la figure 8, on a représenté le poêle à bois 22 muni de son manchon de sortie vertical 23, disposé à l'aplomb ou sensiblement à l'aplomb du conduit d'évacuation de fumée 24 qui dépasse sous le plafond 25 et qui est raccordé à une cheminée (non visible).
On a aussi représenté le conduit de raccordement 1, en deux tronçons emboitable 1a et 1b, non encore installé.
Comme illustré sur la figue 9, la première opération de montage consiste à positionner le collier de fixation inférieur 6 sur le tronçon inférieur 1a du conduit de raccordement 1 et à mettre en place ce dernier verticalement, dans le prolongement de la sortie 23 du poêle 22. Le collier 6 doit alors être positionné à quelques centimètres (par exemple à 6 cm) au-dessus de la face supérieure du poêle 22.
Ensuite (figure 10), l'enveloppe cylindrique 3, constituée des deux éléments télescopiques 4 et 5 en position au moins partiellement rétracté, est emmanchée sur ce premier tronçon de conduit 1a, l'élément inférieur 4 de l'habillage venant reposer sur l'extension 16 du collier inférieur 6 par l'intermédiaire de la bordure inférieure 11 de sa virole intégrée 10 (comme illustré sur les figures 4 et 5). On règle alors le dispositif d'habillage ventilé 2 en orientation de sorte à placer l'échancrure basse 8 du coté de la face avant de l'appareil 22.
L'opérateur poursuit le montage du raccordement 1 en installant son tronçon 1b jusqu'au conduit d'évacuation 24. Il positionne le collier supérieur 7 au niveau de la partie supérieur de ce tronçon de conduit 1b (figure 11), en respectant une distance de quelques centimètres (par exemple 6 cm) entre ledit collier 7 et la finition plafond 25.
L'élément supérieur 5 de l'enveloppe 3 est alors remonté (en coulissant dans l'élément inférieur 4) et il est fixé sur le collier supérieur 7 par l'intermédiaire de la vis 20 (qui passe dans l'orifice 21 ménagé dans l'élément d'enveloppe 5 et qui vient se loger dans l'écrou 19 prisonnier du collier 7).
L'échancrure 9 ménagée dans l'élément supérieur d'enveloppe 5 est également orientée du coté de la face avant du poêle 22.The installation of the ventilated covering device 2 on the connecting pipe 1 equipping a wood stove is illustrated on the Figures 8 to 12 .
On the figure 8 there is shown the wood stove 22 provided with its vertical outlet sleeve 23, disposed vertically or substantially vertically above the smoke outlet duct 24 which projects below the ceiling 25 and which is connected to a chimney (non visible).
It also represented the connecting pipe 1, nestable into two sections 1a and 1b, not yet installed.
As illustrated in FIG. 9, the first mounting operation consists in positioning the lower fixing collar 6 on the lower section 1 a of the connecting duct 1 and putting it in place vertically, in the extension of the outlet 23 of the stove. 22. The collar 6 must then be positioned a few centimeters (for example 6 cm) above the upper face of the stove 22.
Then ( figure 10 ), The cylindrical casing 3, consisting of two telescopic elements 4 and 5 in position at least partially retracted, is fitted on this first duct section 1a, the bottom 4 of the covering element resting on the extension 16 of the lower collar 6 via the lower edge 11 of its integrated ferrule 10 (as shown in FIGS. Figures 4 and 5 ). The ventilated cladding device 2 is then adjusted in orientation so as to place the lower recess 8 on the side of the front face of the appliance 22.
The operator continues to mount the connection 1 by installing its section 1b to the exhaust duct 24. It positions the upper collar 7 at the upper part of this duct section 1b ( figure 11 ), respecting a distance of a few centimeters (for example 6 cm) between said collar 7 and the ceiling finish 25.
The upper element 5 of the envelope 3 is then raised (by sliding in the lower element 4) and it is fixed on the upper collar 7 by means of the screw 20 (which passes into the orifice 21 formed in the casing element 5 and which is housed in the nut 19 prisoner of the collar 7).
The notch 9 formed in the upper shell member 5 is also oriented on the side of the front face of the stove 22.

L'enveloppe cylindrique 3 est alors correctement maintenue de manière concentrique par rapport au conduit de raccordement 1. Cette concentricité est obtenue par les moyens de centrage 16,18 ; la vis de fixation 20 assure la tenue mécanique de l'élément d'enveloppe supérieur 5 ; la virole 10 qui coopère avec le collier inférieur 6 permet à l'élément d'enveloppe inférieur 4 de ne pas venir en appui direct contre le poêle 22.The cylindrical casing 3 is then correctly held concentrically with respect to the connecting duct 1. This concentricity is obtained by the centering means 16, 18; the fixing screw 20 ensures the mechanical strength of the upper casing element 5; the ferrule 10 which cooperates with the lower collar 6 allows the lower casing element 4 not to bear directly against the stove 22.

Par la ventilation réalisée entre les deux parois 1 et 3 la température sur la paroi externe 3 est très fortement abaissée ce qui diminue le risque de brûlure pour l'utilisateur en cas de contact direct avec le raccordement, et ce qui permet de réduire la distance de sécurité minimale entre le raccordement et le mur le plus proche (distance minimum de 1 D).By the ventilation made between the two walls 1 and 3 the temperature on the outer wall 3 is very strongly lowered which reduces the risk of burning for the user in case of direct contact with the connection, and which reduces the distance minimum security between the connection and the nearest wall (minimum distance of 1 D).

L'aspect télescopique de l'enveloppe 3 facilite sensiblement la pose du dispositif d'habillage, et la présence des deux colliers de fixation serrant 6 et 7 permet d'éviter tout perçage dans le conduit de raccordement 1.
On comprend aussi qu'un tel dispositif d'habillage ventilé peut être installé sur un nouveau conduit de raccordement, au moment de la première installation de l'appareil de chauffage, mais aussi sur tout conduit de raccordement préexistant (après démontage de ce dernier).The telescopic appearance of the casing 3 substantially facilitates the installation of the cladding device, and the presence of two clamping fastening clamps 6 and 7 prevents any drilling in the connecting duct 1.
It is also understood that such a ventilated cladding device can be installed on a new connecting duct, at the time of the first installation of the heater, but also on any pre-existing duct connection (after disassembly of the latter) .

L'enveloppe 3 peut être proposée en plusieurs finitions ou coloris ; elle peut aussi être repeinte dans la couleur souhaitée, sur le chantier.
On notera encore qu'on peut envisager de concevoir des formes d'enveloppe 3 autres que cylindrique (section ovale, polygonale...) sans que cela change le principe de réalisation et de pose de l'habillage ventilé conforme à l'invention.The envelope 3 can be proposed in several finishes or colors; it can also be repainted in the desired color on the site.
It will also be noted that it is conceivable to design envelope shapes 3 other than cylindrical (oval section, polygonal section) without this changing the principle of making and fitting the ventilated covering according to the invention.
