INTRODUCTION
1.0 EVOMAX CASCADE FLUE SYSTEM
1.1 INTRODUCTION
The Cascade Flue system enables Evomax boilers of ‘open
flue’ Type B23 to be connected via a common flue header.
The Cascade Header may be coupled to a bespoke flue outlet
system designed by a flue specialist (section 3).
To ensure safety of operation non-return valves are
incorporated to prevent back-flow of combustion products
through any individual boiler that is not firing.
The condensate produced within the flue drains through the
central trough of the header duct and exits via a siphon.
The maximum permissible system capacity is limited to
the value shown in Table 1.2; this is necessary to ensure
acceptable operation of any individual boiler operating at
its minimum output under the influence of the total system
pressure generated by the adjacent boilers.
There are optional system configurations that will provide
different characteristics, these options should be considered to
optimise the system performance. (Table 1.2).
1.2 SYSTEM CONFIGURATIONS
Choosing the most appropriate configuration to the required
application will influence the performance in the following ways;
•
System Capacity.
•
Number of Boilers
•
Turn-Down capability
•
Flue length capability
