Performance required according to the designation
Temperature level T120 working with a nominal fumes temperature at less than 120°C
Pressure level P1



working with a positive and negative pressure up to 200Pa. Permitted loss less than 0.006 l/m2
working with a positive and negative pressure up to 5000Pa. Permitted loss less than 0.006l/sm2
Resistance to condensation W working with moist and dry fumes
Resistance to corrosion V2 working with Gas, LPG and Diesel oil with a sulphur content ≤ 0.2% in mass
Place of installation I only inside buildings
Reaction to fire D on a scale that goes from F (products that cannot be classified as fire resistant) to A1 (products that in no way contribute to any phases of a fire). Class D are products that can resist the action of a small flame for a short length of time with no substantial spreading of the fire.
Wall class L no external protection
Resistance to fire from inside O not fire resistant from inside
Distance from combustible materials (20) (20)=minimum 20mm;



  • Position the elements with the female socket facing up.
  • Use the sliding element for the male-female connection and always maintain a 3° slanting angle on horizontal installations.
  • Observe the compression loads and the non-vertical installations.


Resistance to the wind load:

  • Distance between wall brackets: NPD m
  • Free length from the last bracket: 3 m

Compressive strength:

  • Linear elements’ maximum load: 30m
  • Maximum load of a straight fitting at 90°: 30m
  • Maximum load of the wall chimney support

30m Tensile and bending strength (linear elements):

  • Maximum load at traction (element connection means and chimney connections): NPDm
  • Non-vertical installations: NPD
  • Non-vertical installations: distance between wall chimney supports = NPD

Traction and bending strength (non-linear elements):

  • Non-vertical installations: NPD


Scheduled maintenance carried out by qualified personnel:

  • Unless standards dictate otherwise or different agreements are reached with the user, the following maintenance schedule is advisable:
    • gaseous fuels: 1 / year;
    • liquid fuels: 1 / 6 months;
  • Clean the smoke duct with a soft plastic brush or sponge as well as the equipment compartment for pipe supply and ventilation, the inspection fitting and chimney and also make sure the smoke/fumes and condensates etc., are flowing freely.
