Multiline Cascade Flue System

For multiple boiler installations M&G has Multiline. It is the most versatile PP-flue system for cascade. The even grey and robust Multiline system is easily applicable for any cascade set-up of condensing appliances.

The modular system consists of a limited number of components, to build a reliable PP cascade flue system in no-time.

The benefits of PP material

  • Fast: PP pipes are lightweight, simply made-to-fit and easy to install.
  • Safe: no sharp metal edges that could damage or hurt you.
  • Clean: no corrosion of aluminium, so less pollution in the high efficiency boiler.
  • Sustainable: the high-grade Twinline material is condensate-resistant and tested for long-life. With CE and ULC approval.

Five unique benefits

  • All-round system, applicable to any cascade
    • For line set-ups, back to back set-ups and double line set-ups.
    • For overpressure and under pressure systems.
    • Standard in three collector pipe diameters: 130, 150 and 200 mm (Another diameter? Ask for the possibilities).
    • Standard applicable for two to eight appliances, can be extended to bigger configurations.
    • Apart from the concentric 100/150 mm connection on the appliance, a parallel 100-100 mm connection is also possible.
  • Optiflow-quality, best flue discharge
    Multiline is a modular system of high-quality injection moulded parts. This leaves the inner wall completely smooth and the flue discharge will be optimal, because it is unhampered by edges from the welding. The fact that the parts are not welded is also a guarantee for their perfect dimensional stability.
  • Smart elbows, extra sustainable
    Multiline elbows do not only have a perfectly smooth inner wall, but they have been constructed in such a way that condensate cannot remain behind. All elbows are fitted with a clever discharge flume. Influence of condensate is thus prevented, which is favourable for the sustainability.
  • Eccentric reduction, robust construction
    A Multiline flue system has an excentric reduction which adjusts the distance to the back of the boiler. This simplifies the installation. In addition, the fact that there are less parts makes the construction more robust.
  • Easy kit, quick and easy to install
    A robust even grey Multiline flue system can be put together quickly. The practical basic and extension kits make ordering the necessary kit unbelievable easy.

Note: First consult boiler manufacturer specifications for the correct diameters and lengths.
