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.

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.
