E93.9950EN CB Cascade manual
1. Introduction
This Cascade manual is intended for the wall-hung high efficiency central heating boilers from the CB boiler
series as manufactured by ECO Heating Systems.
The boilers can be combined in one cascade configuration. This ensures that the required power can always be
achieved. Since several boilers are combined this allows for a deeper modulation range and for more precisely
achieving the required level.
Furthermore the cascade configuration offers an increased reliability: should one boiler go into error, the
cascade configuration will continue to operate.
ECO Heating Systems can supply standard cascade systems with mounting frame, piping and low loss headers
for up to six boilers depending on the range. Larger amounts of boilers in a cascade combination are possible
but require a dedicated system which must be designed separately.
The software allows for combining of up to 16 CB-boilers in a single cascade installation.
This document will offer you a general procedure for the complete installation of a cascade configuration.
For specific details regarding connections, parameters, venting, etc. see
the Installation & Service Manual of the
boilers.
