Safety Device Kit G 2 1/2" For Boilers In Cascade Configuration Victrix Pro 35 1 I - 55 1 I - Immergas VICTRIX PRO 1 I Series Technical Sheet

17 SAFETY DEVICE KIT G 2 1/2" FOR BOILERS IN CASCADE CONFIGURATION
The modular boilers, i.e. appliances comprised of multiple boilers
set up by the manufacturer to operate in cascade (battery) with
an original Immergas hydraulic manifold kit, must be considered
a unique appliance, which assumes the serial number (factory
number) of the boiler nearest to the safety devices. It is therefore
possible to set up up to 5 modules side-by-side, with a single safe-
ty kit. With outdoor installation it needs to be protected using
the IPX4D protection box kit for cascade boiler configuration
safety devices, code 3.024038, or nonetheless protected from the
elements based on its electrical protection rating.
Immergas declines all liability whenever the installer does not
use original Immergas devices and kits, or uses them improperly.
The sensitive elements of the safety devices must be set up as
described in the installation instructions, in compliance with
the provisions cascade forth in the ''R'' collection.

manual reset minimum pressure switch (the boiler is already
equipped as per standard with 4-bar safety valve and standard
draining funnel).
There is a fitting for an expansion vessel on the flow and return
stub pipes.
N.B.: The figure illustrates safety device kit installation with the
outlet on the right side, however, it is also to install the kit with
the outlet on the left side.
