General features.
VICTRIX Plus is a condensation type wall-hung room sealed
fan-assisted boiler for central heating only, designed to work
with a Plus storage tank with an 80, 105, 120 or 200-litre
capacity.
anks to the condensation technology this boiler stands out
for its high performance and wide modulation range (from
20% to 100% of nominal heat power).
ere are two versions in the range with working outputs of
23.5 kW (20210 kcal/h) and 32.0 kW (27520 kcal/h) and
both models feature an innovative total premix combustion
system that ensures minimal pollution emissions. ey can
run on natural gas or LPG.
anks to their excellent energy performance, these boilers
bear the 4-star mark (´´´´) in conformity with the P.D.
660/96.
e appliance is regulated and controlled by means of a printed
microprocessor control board which, via a display, shows the
state of boiler operation (temperatures, safety devices, etc.) and
enables it to be connected (optional) to the Remote Control,
to the external probe, to the zone control unit and to the
Multisystem Distribution Manifold.
e hydraulic circuit features a water-gas coil exchanger in
stainless steel, a 3-way hydraulic diverter valve and an adjustable
by-pass on the system.
All boilers are fitted with an antifreeze device for temperatures
of -5 °C.
e VICTRIX Plus boiler has to be installed using the suc-
tion/exhaust kit or the ducting systems (60 mm Ø rigid and
80 mm Ø flexible) made of plastic and expressly conceived for
the Immergas condensation boilers.
e AISI 316L stainless steel storage tanks are supplied with
an anode and domestic hot water expansion vessel as standard
features and can be connected to the recirculation system by
means of a specific kit (optional).

e primary circuit with relevant control and safety devices is
triggered each time there is a request for central heating or
domestic hot water.
Operation.
e heat contained in the products of combustion is absorbed
by the pipes of the coil water-gas exchanger fitted in the con-
densation module (14) which, in turn, transfers it to the water
circulating inside thanks to the boiler pump (26).
When the boiler is working only in the central heating mode,
the water is transferred directly into the system while if it is
coupled to the storage tank it can be diverted to inside the
storage tank coil.
is depends on the position of the electric 3-way diverter valve
(5) which, depending on the request, permits flow through the
system delivery (M) and return (R) pipes, or it diverts the flow
to the storage tank coil.
Flow-head graph.
e trend of the curve that represents the flow-head ratio,
depends on how the system by-pass is adjusted. Depending
on the position, it provides the system with a higher or smaller
head. Circulator.
e circulator works on the primary circuit return and is
located on the brass assembly.
It is connected to the enbloc by means of a threaded connec-
tion while the condensation module and the expansion vessel
are connected by means of coupling pipes (2) and an O ring
(3), locked by special forks (1).
Primary exchanger (see VICTRIX).
