Installation

Position the components as indicated by the arrow stamped on the label and shown on the piece.
When using T200_P1_W, place the sealing ring in the appropriate seat located in the female socket.
The sealing ring must be positioned with the three lips facing towards the inside of the pipe.
To prevent damage and facilitate insertion, talc or soap must be used.
For use at T600_N1_D, use the product without the sealing ring.
After connecting the components, fit and tighten the appropriate locking clamp at each joint.
Respect compression loads and non-vertical installation requirements.
Avoid the accumulation of condensate or soot, which may cause corrosion. Also avoid horizontal sections and, in any case, install the elements with the longitudinal weld facing upwards (3% slope).

Scheduled maintenance carried out by qualified personnel:

Unless otherwise required by regulations or agreed with users, the following maintenance intervals are recommended:
- Gaseous fuels: once per year;
- Liquid fuels: once every 6 months;
- Solid fuels: once per month.
Cleaning using a soft plastic brush or sponge of the flue pipe, the technical compartment for air supply and ventilation of the ducts, the inspection connection, the chimney cap; checking the free flow of flue gases and condensate, etc.
