Vaillant Flue Extension 0.5 m, Ø 200 mm

Product detailed description

Flue extension 0.5 m Ø 200 mm is the shortest straight section available in the range of extensions for the Vaillant DN 200 PP flue system. It is used wherever the exact length of the flue route needs to be fine-tuned - for example as the last short section before the outlet, between two elbows, or to bridge a small distance where a longer 1.0 or 2.0 m section would be unnecessarily oversized.

The Vaillant DN 200 PP flue system is an original component system for discharging flue gases from high-capacity condensing boilers of the ecoCRAFT exclusiv series (and, in some projects, also from cascade arrangements of several Vaillant condensing boilers connected to a common flue collector). It is a single-wall plastic pipe made of durable polypropylene (PP), which - given the low flue gas temperature typical of condensing technology (usually up to approx. 80 °C) - is a fully adequate and more cost-effective alternative to metal stainless-steel flues used with older atmospheric or low-efficiency heat sources. Extensions in three lengths (0.5 m, 1.0 m and 2.0 m) allow the flue route to be assembled precisely to the required height or distance by combining a suitable number of individual sections, instead of cutting longer pipes to size, which could compromise the tightness of the joint or the system's certification.

Technical characteristics

• Length - 0.5 m, the shortest section available in the range of extensions
• 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 - 0020095549
• Joint type - socket connection with sealing ring at both ends
• Typical use - fine-tuning the exact length of the route, short bridging between elbows

Installation and use in the flue route

The 0.5 m extension is used in the route to fine-tune the exact total length of the flue when the sum of longer sections (1.0 m and 2.0 m) does not reach exactly the required distance between the boiler and the connection or outlet point. It is installed with a socket connection with a sealing ring at both ends, the same as other straight sections of the DN 200 PP system. The exact combination of lengths of individual extensions for your specific route is determined by the flue route design project; installation should only be carried out by a professionally qualified company authorised to install flue systems for condensing boilers. During installation, it is also necessary to observe the prescribed slope of horizontal sections towards the condensate drain, so that accumulated condensate can flow freely and does not remain standing in the pipe.

Compatibility and system integration

This section is fully compatible with the other components of the DN 200 PP system listed in the overview table below - elbows of all angles, inspection elements and spacer brackets. When a larger distance needs to be bridged, it is more advantageous in terms of the number of joints to use a smaller number of longer sections (1.0 m or 2.0 m) and use the 0.5 m extension only to fine-tune the remaining difference in length.

How to design the exact route length by combining extensions

The Vaillant DN 200 PP flue system offers extensions in three standard lengths - 0.5 m, 1.0 m and 2.0 m - which can be combined as needed so that the sum of the lengths exactly matches the required distance between the boiler, elbows, inspection elements and the connection or outlet point of the route. Instead of cutting a single long pipe to the exact size on site (a common practice with some cheaper or non-original systems, which carries the risk of damaging the socket joint), the exact length is achieved solely by combining original certified sections.

When designing the exact composition of the route, the designer usually starts from the total measured distance, subtracts the lengths of all elbows and inspection elements used (these have their own installation length stated in the manufacturer's technical documentation), and covers the remaining difference with a combination of extensions. In most cases, a combination of one or two longer sections (1.0 m or 2.0 m) supplemented by one shorter 0.5 m extension is enough to fine-tune the exact remainder.

A practical recommendation is to allow a slight reserve when ordering material - if the calculation comes out right on the boundary between two possible length combinations, it is generally better to order an extra 0.5 m extension as a reserve than to risk being just a few centimetres short of the required route length on site.

We will gladly prepare an exact calculation of the required combination of extensions for your specific building based on the measured height or route length, and the type and number of elbows and inspection elements used - simply contact us with this information before ordering the material.

In cascade boiler rooms, where each connected boiler has its own branch leading to a common flue collector, the length of individual branches usually differs depending on the physical location of the boilers in the boiler room - this is where the possibility of combining three different extension lengths is most useful, since each branch may require a different exact length without the need to order specially manufactured non-standard pipe lengths.

The short 0.5 m extension has also proven useful in practice as a handy reserve during service interventions, when part of the route needs to be temporarily extended while replacing another damaged section - given its low price and small size, it is worth always having at least one piece on hand in the service company's warehouse.

Maintenance, service and inspection

Straight extensions do not require separate maintenance; their condition is checked during the annual inspection of the flue route through the nearest inspection access points along the route. Due to its short length, this extension is the least demanding straight section in the range in terms of mechanical stress and risk of sagging, but for longer assembled sections it is still necessary to observe the prescribed spacing of spacer brackets along the entire length of the route, including this section.

Why choose an original Vaillant part

Thanks to the range of three different extension lengths (0.5 m, 1.0 m and 2.0 m), the route can be assembled precisely to size without the need to cut pipe on site, which could compromise the quality of the joint and the system's certification. The original Vaillant part has a precisely defined diameter and wall thickness corresponding to the certification of the entire ecoCRAFT exclusiv system, which guarantees the tightness of joints as well as maintaining the warranty on the boiler and flue route. As a verified supplier of original Vaillant parts (WINTNER s.r.o.), we can guarantee the origin and quality of every piece supplied.
