Commissioning - IDEAL Evomax 30 Manual

4.0 COMMISSIONING

To accommodate the flue pressure generated by the
connection of multiple boilers to a common flue, the minimum
rate (equivalent to minimum fan speed) of each Evomax
appliance operating on the Multiline cascade system is
increased to offset the maximum back-pressure created.
Table 4.1 shows the revised performance of each Evomax
model where it differs from standard standalone operation as
shown in the Evomax Installation & Servicing instructions.
To convert Evomax operation with the Multiline flue as
described, the change is made by accessing the operating
parameters on the Evomax user interface control panel
following the procedure below. This change must be made to
each Evomax operating on the Multiline cascade system.
