XL - F / cascade installation
Cascade
In principle, any combination is possible depending on the installation requirements. The selection of the models can
be different outputs. Including boilers with common outputs assists with sharing the load and run times of individual ap-
pliance.
The capacity of the hydraulic pipes, gas line, and low loss header are adjusted to the selected overall demand.
When installing the a single XL - F boiler or cascade XL - F boilers, the use of a low loss header adjusted to the set de-
mand is strongly suggested. ATAG Heating Solutions offer optional matched low - velocity mixing headers suitable for
heat outputs up - to 1600kW.
