Vaillant Flue Extension 1.0 m, Ø 200 mm

Product detailed description

Flue extension 1.0 m Ø 200 mm is a medium-length, most universally used straight component from the range of Vaillant DN 200 PP flue extraction system extensions. Thanks to its length, it represents a practical basic building module for spanning the typical height of one floor or a medium distance in the horizontal section of the route.

The Vaillant DN 200 PP flue extraction system is an original component system for removing flue gases from high-capacity condensing boilers of the ecoCRAFT exclusiv range (and in some projects also from cascade assemblies of several Vaillant condensing boilers connected to a common flue gas collector). It is a single-wall plastic pipe made of durable polypropylene (PP), which, due to the low temperature of flue gases from condensing technology (typically up to approx. 80 °C), is a fully-fledged and more cost-effective alternative to metal stainless steel flues used in older atmospheric or low-efficiency heat sources. The 1.0 m length is in practice the most frequently ordered extension from the entire range, as it corresponds well to the typical floor-to-floor height in family houses and smaller commercial buildings, while also allowing faster installation with fewer joints than repeated use of shorter 0.5 m components. For greater heights or route lengths, this component is commonly combined with the longer 2.0 m extension.

Technical characteristics

• Length - 1.0 m, the most universal length in the range of extensions
• Material - polypropylene (PP), resistant to flue gas condensate
• Nominal diameter - DN 200, for the ecoCRAFT exclusiv system
• Design - straight component without inspection opening
• Manufacturer's order number - 0020095550
• Joint type - socket connection with sealing ring at both ends
• Typical use - spanning floor height, medium-length horizontal sections of the route

Installation and use in the flue route

The 1.0 m extension is most commonly used in practice to span the typical height of one floor in a vertical section of the route, or as a medium-length building module in a horizontal run to the boiler or to a common flue gas collector. It is installed with a socket connection with a sealing ring at both ends, the same as other straight components of the DN 200 PP system. The exact combination of lengths for your specific route is determined by the flue gas path project; installation should only be carried out by a professionally qualified company with authorization to install flue gas systems. On horizontal sections, the prescribed slope toward condensate drainage must be maintained. On vertical runs, it is recommended to continuously check the verticality of the route with a level after each installed component before continuing to the next section, so that any inaccuracy does not accumulate over a greater height.

Compatibility and system integration

The component is fully compatible with other components of the DN 200 PP system listed in the overview table below - elbows of all angles, inspection elements, and spacer holders. For greater heights or distances, the 1.0 m extension is combined with the longer 2.0 m component and the shorter 0.5 m component to precisely fine-tune the total route length according to the project. Like other components of this range, the extension is not interchangeable with components of other diameters of Vaillant flue extraction systems, such as DN 110/160 mm or DN 130 mm.

Number of joints versus component length - impact on tightness and costs

When designing the combination of extensions for a specific route, it is important to consider not only the total required length but also the number of resulting joints between individual components. Each socket joint with a sealing ring is structurally safe and certified for the given operation; nevertheless, the general principle applies that fewer joints for the same total route length means a somewhat lower theoretical risk of leakage over many years of operation, since each joint is a point where a visual tightness check is later performed.

The 1.0 m extension represents a reasonable compromise in this respect between the short 0.5 m component (more joints for the same length, but greater flexibility in fine-tuning the exact measurement) and the long 2.0 m component (fewer joints, but less flexibility and more difficult handling during installation in confined shaft spaces). That is precisely why the 1.0 m component is in practice the most commonly used basic building module when assembling the route.

From an economic point of view, the price of the individual extension lengths roughly corresponds to the amount of material used, so the choice between several shorter or fewer longer components for the same total route length does not have a significant impact on the total material cost - the decisive criterion should therefore primarily be the practicality of installation and minimizing the number of joints, especially in hard-to-reach places along the route.

When combining several lengths, we also recommend taking into account the handling options at the specific construction site - in narrow or hard-to-reach shafts, handling the longer 2.0 m component may be more difficult than the shorter 1.0 m or 0.5 m component, which may be another reason to choose shorter components even where a longer component would theoretically mean fewer joints.

When ordering material at atria.sk, we recommend always specifying the total planned height or length of the route and the boiler type - based on this information, we will be happy to suggest the optimal combination of extension lengths, taking into account both the number of joints and the practicality of handling at the specific construction site.

The 1.0 m extension is also a component worth keeping in stock by service companies as a standard reserve in case it is necessary to replace a damaged part of the route during a service intervention - its universal length covers most common situations without the need for a special custom order.

Maintenance, service and inspection

Straight extensions do not require separate maintenance; their condition is verified during the annual inspection of the flue gas path through the nearest inspection access points along the route. For longer assembled sections, it is necessary to maintain the prescribed spacing of spacer holders along the entire length of the route, including this component, to prevent sagging of the pipe between individual mounting points. If replacement is necessary, the component is simply pulled out of the socket joints on both sides and replaced with a new original piece of the same length and diameter.

Why choose an original Vaillant component

Thanks to its universal length, the 1.0 m extension is the most frequently ordered component from the entire range of extensions - it corresponds well to the typical floor height and reduces the number of joints needed compared to repeated use of shorter components. The original Vaillant component has a precisely defined diameter and wall thickness corresponding to the certification of the entire ecoCRAFT exclusiv system, which guarantees the tightness of the joints as well as the preservation of the warranty on the boiler and flue gas path. As a verified supplier of original Vaillant components (WINTNER s.r.o.), we can guarantee the origin and quality of every piece supplied.
