MF - DOUBLE WALL INSULATED - STAINLESS STEEL CHIMNEY SYSTEM

Highlights

MF is a modular, double-walled and pre-insulated flue gas system and exhaust air system made of stainless steel with a special internal lip seal. It can be used universally at low and high temperatures with and without condensation in negative and positive pressure. MF is therefore suitable for a wide range of applications such as condensing boilers, low temperature and solid fuel fireplaces and is soot fire resistant. We have summarized all the advantages of the flue gas pipe for you:

Multi - Functional

MF is a modular, double-walled and pre-insulated flue gas/exhaust air system made of stainless steel with a special internal lip seal. It can be used universally at low and high temperatures with and without condensate accumulation in negative and positive pressure. The inner and outer walls are made of high-quality stainless steel.

Guaranteed quality

Only the highest quality materials and precision are used in the production of the MF chimney. Due to its proven quality, the MF flue gas and exhaust air system is guaranteed for 10 years.

Wide range of applications

MF is a flue gas and exhaust air system for almost all areas of application. The universally applicable system is suitable for ovens, industrial plants, tiled stoves, open fireplaces, condensing boilers, low-temperature and solid fuel fireplaces. In passive houses, the system can be combined with the Isoblock, a compact wall and ceiling penetration through combustible building materials. It can also be used as a supply and exhaust air system.

Variants

This system is available as a Standard edition and as a stylish Design edition for in-sight installation.

Standard edition

MF's standard edition is made of stainless steel with a high quality insulation and no thermal bridges.

Design edition

Since 2014 we provide Design edition chimneys in our product series AT, MF, US and UE. Design edition chimneys have an outer wall that is completely smooth and flat, without beats or locking bands. These design-edition chimney parts are suitable for in sight, vertical, installation inside, and not as a free-standing or a outside mounted chimney.

The system structure

The MF system has multiple system configuration possibilities due to its multifunctional application. MF can both be installed as the connecting chimney system, as well as the main chimney system. Generally the MF system is mounted on the wall or on the floor. This includes the inspection/cleaning door and all other components. After the wall duct to the respective heating system, the flue gas system is topped off with an outlet cone.
