A cascade control room is available on demand, allowing advanced management of the two<br />
shells inside the boiler. Each control room is capable of controlling a maximum of 5<br />
furnaces. As a consequence the number of control rooms being necessary for such<br />
operation changes depending on the number of REPLY N modules connected (see table on<br />
your right).<br />

sure that the header and flue diameter values correspond to those reported in the table below.<br />
Warning: The header shall feature a slope towards the<br />
condensation discharge amounting to at least 3°.<br />
