e modular boilers, i.e. appliances comprised of multiple
modules set up by the manufacturer to operate in cascade
(set) with an original Immergas hydraulic manifold kit, must
be considered a unique generator, which assumes the serial
number (factory number) of the thermal module nearest to
the INAIL safety devices. It is therefore possible to ank up to
5 modules, with a unique INAIL safety kit.
With outdoor installation it needs to be protected using the
IPX4D protection box kit for set boiler conguration INAIL
safety devices, code 3.024038, or nonetheless protected from
the elements based on its electrical protection rating.
Immergas S.p.a. declines all liability whenever the installer does
not use the devices and INAIL-approved Immergas original kits
or uses them improperly.
e sensitive elements of the INAIL safety devices must be set
up as described in the installation instructions, in compliance
with the provisions set forth in the ''R'' collection.
For INAIL design purposes, by installing the Immergas safety
Immergas, there are already the following type-approved
INAIL devices: Manometer-holder cock, manometer, ther-
mometer, manual reset thermostat, manual reset maximum
pressure switch, and manual reset minimum pressure switch
(the boiler is already equipped as per standard with 4-bar safety
valve and standard draining funnel).
ere is a tting for an expansion vessel on the ow and return
stub pipes.
N.B.: e gure illustrates the INAIL safety device kit instal-
lation with the outlet on the right side, however, it is also to
install the kit with the outlet on the le side.
