Abstract

Gasbeheizter Wassererhitzer mit einer geschlossenen Verbrennungs­ kammer (10) und einer geschlossenen Frischluftkammer (20), die über einen Anschlußkrümmer (30), der aus einem Abgasrohr (32) und einem dieses umgebenden Frischluftrohr (34) besteht, mit einem weiter­ führenden Doppelrohr (40) verbunden sind. Zum Verbinden des Abgas­ rohres (32) mit einem Abgasstutzen (16) am Wassererhitzer ist eine Manschette (36) vorgesehen, die auf dem Anschlußstutzen (16) soweit nach unten verschiebbar ist, daß der Anschlußkrümmer (30) von vorn über den Abgasstutzen (16) und die Manschette (36) geschoben bzw. geschwenkt werden kann. Eine Frischluftöffnung (22) der Frischluft­ kammer (20) ist von einem Kragen (24) umgeben, dessen hintere Ring­ hälfte (56) das Frischluftrohr (34) umfaßt und dessen vordere Ring­ hälfte (54) axial so tief ausgespart ist, daß sie das Aufschieben bzw. Aufschwenken des Anschlußkrümmers (30) auf den Anschlußstutzen (16) nicht behindert. Das Frischluftrohr (34) wird danach durch eine Schelle (38) am Kragen (24) festgespannt. Dadurch ergibt sich eine einfache Montage der Teile, bei welcher nur eine Manschette (36) verschoben und eine Schelle (38) aufgesetzt werden muß. Gas-fired water heater with a closed combustion chamber (10) and a closed fresh air chamber (20), which a manifold (30) consisting of an exhaust pipe (32) and a this surrounding fresh air pipe (34) exists with a further leading double tube (40) are connected. For connecting the exhaust gas Pipe (32) with an exhaust pipe (16) on the water heater is one Cuff (36) provided, as far as on the connecting piece (16) can be moved downwards that the connection elbow (30) from the front pushed over the exhaust pipe (16) and the sleeve (36) or can be pivoted. A fresh air opening (22) of the fresh air Chamber (20) is surrounded by a collar (24), the rear ring half (56) comprises the fresh air pipe (34) and its front ring half (54) is axially recessed so deep that it can be pushed open or pivoting the connection elbow (30) onto the connection piece (16) not hindered. The fresh air pipe (34) is then replaced by a Clamp (38) clamped to the collar (24). This results in a simple assembly of the parts, in which only one sleeve (36) moved and a clamp (38) must be put on.
