INSTALLATION AND OPERATING MANUAL
These models are tted with a circulation pump.
This silent-running high-head pump is suitable for use on any type of heating system.
The pump, mounted inside the appliance, is tted out for operation at maximum speed (III). Speed I should not be used
as ow rate/head performance does not satisfy normal operating conditions.
make sure the circuit pressure drops downline from the module are compatible with the supplied pump. In this case, the
column pump must only offset the circuit pressure losses upline from the module (a residue head is acceptable).
The circulating ow rate value is shown on the heat meter display (see §17).
A device for balancing the load circulating in the heating plant is located in the brass body of the hydraulic assem-
bly (figure 6). For these models, check that the lever of this device is wide open.
