Vaillant Flue Extension 2.0 m, Ø 200 mm

Product detailed description

Flue extension 2.0 m Ø 200 mm is the longest straight section available in the range of Vaillant DN 200 PP flue extraction system extensions. It is used to bridge longer distances - for example, the height of several floors in a vertical run, or longer horizontal sections towards a common flue gas collector - with as few joints as possible.

The Vaillant DN 200 PP flue extraction system is an original component system for removing flue gases from large-capacity condensing boilers of the ecoCRAFT exclusiv series (and in some projects also from cascade assemblies of several Vaillant condensing boilers connected to a common flue gas collector). It is single-wall plastic piping made of durable polypropylene (PP), which - given the low flue gas temperature of condensing technology (typically up to approx. 80 °C) - is a fully adequate and more cost-effective alternative to stainless steel flue pipes used with older atmospheric or low-efficiency heat sources. On long runs in multi-storey shafts or in larger cascade boiler rooms, using this longest section brings a noticeable reduction in the number of joints compared to using multiple shorter 0.5 m or 1.0 m sections to achieve the same total length.

Technical characteristics

• Length - 2.0 m, the longest section in the extension range
• Material - polypropylene (PP), resistant to flue gas condensate
• Nominal diameter - DN 200, for the ecoCRAFT exclusiv system
• Design - straight section without inspection opening
• Manufacturer order number - 0020095551
• Joint type - socket connection with sealing ring on both ends
• Typical use - long vertical sections in multi-storey shafts, long horizontal runs

Installation and use in the flue run

The 2.0 m extension is used mainly for longer vertical sections in multi-storey shafts or for longer horizontal runs towards a common flue gas collector in cascade assemblies. It is installed using a socket connection with a sealing ring on both ends, just like the other straight sections of the DN 200 PP system. Due to the greater length and weight of the section, more demanding handling should be expected during installation, especially in confined shaft spaces - we therefore recommend always entrusting the handling to an experienced installation company with a sufficient number of workers for safely lifting and inserting the section into the joint. On horizontal sections, it is essential to maintain the prescribed slope towards condensate drainage along the entire length of the section.

Compatibility and system integration

The section 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 brackets. On long runs, several 2.0 m sections are usually combined with shorter 1.0 m or 0.5 m sections to precisely fine-tune the remaining length according to the flue gas path design. Like the other sections in this range, the extension is not interchangeable with sections of other diameters of Vaillant flue extraction systems, such as DN 110/160 mm or DN 130 mm - always verify the exact diameter of your boiler's flue run before ordering.

When a longer section is worthwhile, and what to consider for transport and handling

The decision between using a single longer 2.0 m section and combining several shorter sections for the same total length should not be based on material cost alone, but also on the practical aspects of the specific installation. A longer section means fewer joints, which is an advantage in terms of installation speed and the number of points that need to be checked during future inspections - on the other hand, it requires more demanding handling, especially in confined shaft spaces or when working at height.

When transporting material to the site, keep in mind that a 2-metre-long section will not fit into a standard passenger vehicle and requires either a van with a sufficiently long cargo area, or delivery directly to the installation site by the supplier. When ordering via atria.sk, it is therefore advisable to consider transport options to the installation site in advance, especially when combined with other bulky sections such as elbows or inspection elements.

When installing into a vertical shaft, we recommend lowering the section from top to bottom with the assistance of at least two workers to avoid damaging the socket end by knocking it against the shaft wall or against sections already installed further down the run. For horizontal runs, it is necessary to continuously check that the prescribed slope is maintained along the entire length of the section during installation, since with such a long piece even a small deviation in slope at one end results in a larger height difference at the other end.

Despite the more demanding handling, using a 2.0 m section on long runs is worthwhile in most cases - fewer joints mean faster installation, fewer points to check during future inspections, and usually lower overall labour costs for the installation company compared to installing the same length of run from a larger number of shorter sections.

When ordering material for larger installations with long runs, we recommend consulting our team in advance about transport as well - when ordering several 2.0 m sections together with other bulky material (elbows, inspection elements, spacer brackets), we can help plan delivery so that the complete material is available on site for a single continuous installation visit without unnecessary downtime.

Finally, even with this longest section, it remains an original certified component directly from the manufacturer Vaillant - its material properties, wall thickness, and the quality of the socket joint are identical to the shorter sections of the DN 200 PP range, only the length differs. By using original sections along the entire run, you retain full warranty coverage for the ecoCRAFT exclusiv boiler as well as for the flue gas path itself.

Maintenance, service, and inspection

Straight extensions do not require separate maintenance; their condition is verified during the annual inspection of the flue gas path via the nearest inspection access points along the run. Given the greater length of this section, it is especially important to maintain the prescribed spacing of spacer brackets along its entire length, to prevent sagging caused by the pipe's own weight and accumulated condensate. If replacement is necessary, the section is simply pulled out of the socket joints on both sides - due to its length, we recommend carrying out the replacement with the assistance of at least two workers.

Why choose an original Vaillant section

On long runs, using this longest section reduces the total number of joints, which simplifies both installation and subsequent inspections and reduces the number of points where tightness needs to be verified during inspection. The original Vaillant section has a precisely defined diameter and wall thickness corresponding to the certification of the entire ecoCRAFT exclusiv system, which guarantees joint tightness and preserves the warranty on the boiler and the 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.
