It is also possible to have an independently installed cascade system con­
sisting of several units. You then determine the position of the boilers and
the piping for your specific situation. To make this easier to do, this chap­
ter provides a summary and description of the components to be used.
The components of the cascade systems are also available individually for
independent assembly. Boiler connection kits can be advantageous be­
cause of their reasonable price and fitting dimensions.
