CASCADE CONNECTION PARAMETERS
When the appliance is installed in sequence/cascade (modular
system with several generators) it is necessary to set on all the
boilers the following INST PAR parameters:
PAR 15 =
0 for the first boiler (MASTER)
1 .... 7 for the other boilers (SLAVE)
(Avoid assigning the same number
to SLAVE boilers)
Boiler connected to a common(cascade) flue. whether working in
cascade or independently must have PAR1 reset
PAR 1 =
8 (for NATURAL GAS boilers)
16 (for PROPANE boilers)
In addition, when the number of boilers in cascade is more than
two, configure the parameters OEM A1 of the MASTER boiler.
(See 2.2.2)
