Cascade installation
Special cascade units (accessories) have been developed
to enable this boiler to be installed in a cascade system.
Every cascade unit includes an installation frame, horizontal
headers, connection pipes for the boiler, main gas pipe and
a vertical low loss header.
Cascade units are available for installing the boilers inline or
back-to-back. These cascade units make installing a
cascade system easier and less labor intensive.
