Flue pipes for gas boilers

A wide range of flue pipes is available, for both non-condensing boilers with forced exhaust (turbo boilers) and condensing boilers as well. The flue pipes are intended for indoor installation only, with the only exception of stainless-steel façade flue pipes that are designed for outdoor installation.

Advantages:

  • easy, quick installation and inspection of flue pipes
  • high strength and tightness of slip-on parts
  • wide range of components in stock for various methods of flue gas exhaust
  • technical support in flue piping design

System components:

The range of products involves connecting flanges, single and twin wall extension pipes, terminals for air intake and flue exhaust, 45° and 90° elbows in single and twin wall versions, sections with inspection holes and taps, wall sealing collars, roof flashings, flue terminations, chimney spacers, sealing O-rings and connection fittings. The slip-on design is used together with special silicone lip seal O-rings, however it is advisable to apply silicone grease (e.g. SCIV-O-RING) on the O-rings for easier connection. Should the flue pipe go through a wall, an outer and inner collars shall be used. If the flue passes through a roof, the appropriate flat/pitched roof flashing shall be used, the pitched roof flashing being suitable for roofs of 18-44° slope. Extension parts can be cut to the desired length. The flue pipe system shall be installed in compliance with the appropriate EN standards, technical rules, boiler manufacturer’s instructions and installation manual.

Flue gas pipes for turbo boilers:

The flue pipes are designed for use with gas boilers of max. flue gas temperature of 200° C, under negative or positive operation pressure. Aluminum is used for flue exhaust. These flue pipes are condensate resistant.

This flue piping is designed either concentric or parallel. Concentric flue pipes are in diameters 60/100 mm or 80/125 mm, flue gas passes through the inner aluminum pipe (60 or 80mm diam.) and combustion air is sucked through the outer metal lacquered pipe (100 or 125 mm diam.). Aluminum twin (parallel) flue pipes for separate intake and exhaust are 80 mm in diameter. Further also single wall flue pipes are available, in diameters of 60 or 100 mm.

Flue pipes for turbo boilers are certified to EN 1856-1:2003.

Flue gas pipes for condensing boilers:

The flue pipes are designed for use with gas- or oil-fired (0.2% sulphur max.) low-temperature and condensing boilers of max. flue gas temperature of 120° C, under negative or positive operation pressure. Polypropylene is used for flue exhaust as it is condensate resistant and well shapeable into separate sections.

This flue piping is designed either concentric or parallel. Concentric flue pipes are in diameters 60/100 mm or 80/125 mm, flue gas passes through the inner polypropylene pipe (60 or 80mm diam.) and combustion air is sucked through the outer lacquered metal  pipe (100 or 125 mm diam.). Polypropylene twin (parallel) flue pipes for separate intake and exhaust are 80 mm in diameter. For outdoor use there is a concentric flue piping 80/125 mm diam. with inner PP pipe and outer in stainless steel. Further also single wall flue pipes are available, in diameters of 60 or 100 mm, and flue pipes for boiler cascades in diam. of 160 mm.

Flue pipes for condensing boilers are certified to EN 14471:2005.
