INSTALLATION INSTRUCTIONS

Flex-istruzioni

  • Position the elements as shown by the arrow printed on the piece.
  • For the connection of the Flex series with other series, the T200_P1_W designation is obtained by using the relevant accessories with seal of art.
  • 4954 (Coupling fitting with seal between screwed FLEX and a rigid single wall element). If T450_N1_D is used, use art.

ESSENTIAL FEATURES

Resistance to the wind load:

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

Compressive strength:

  • Linear elements’ maximum load: 15m

Note: these values refer to the worst conditions. For more info see (Mechanical Strength Table)

30m Tensile and bending strength (linear elements):

  • Maximum load at traction (element connection means and chimney connections): 15m
  • Non-vertical installations: max. 90°

Compressive strength :

  • 7,6 kg m

Note: these values refer to the worst conditions. For more info see (Mechanical Strength Table).

FLUE SYSTEM MAINTENANCE

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;
    • solid fuels:: 1 / month.
  • 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.
