VICTRIX 24 kW
Condensation wall hung room-sealed boiler for
central heating and the instant production of
domestic hot water.
VICTRIX 24 kW
VICTRIX 24 kW is an instantaneous wall-hung room-sealed
(type C) boiler with a nominal heating input of 24 kW (20640
kcal/h) for central heating and 26 kW (22337 kcal/h) for do-
mestic hot water which, thanks to the condensation technology,
stands out for its particularly high performance and ample
modulation range (from 20% to 100 % of the rated output).
e boiler is equipped with a total premix combustion system
that guarantees minimal polluting emissions and it can run on
either natural gas or L.P.G.
e VICTRIX 24 kW series of boilers is type-approved for in-
stallation outside the building in a partly sheltered location.
Note: By a partly sheltered location we mean a place where the
appliance is not exposed directly to the weather (rain, snow, hail,
etc.).
e boiler is adjusted and controlled by a microprocessor
controlled p.c.b. with continuous 2-sensor ame modulation
(d.h.w. and central heating), which, by means of a backlit dis-
play, shows boiler operating status (temperatures, safety devices,
etc.) and it also allows connection (optional) to the Remote
Control, to the external probe, to the zone control unit and
to the Multi-system Distribution Manifold.
e hydraulic circuit is equipped with a water-gas exchanger
with stainless steel heating coil and uses the new hydraulic unit
made in a composite material on which the devices to control
the hydraulic circuit are housed (the system’s absolute pressure
switch, 3-bar safety valve, automatic system by-pass, etc.), besides
the circulator and 3-way electric valve which allows, according
to requirements, the circulation of boiler water in the central

heating system or in a stainless steel plate exchanger for the
instant production of domestic hot water.
One of the boiler’s standard features is an antifreeze device
that protects against temperatures down to a minimum -5°C
(optional down to -15°C).
e VICTRIX 24 kW boiler must be installed using the intake/
outlet kits or ducting systems (60 mm Ø rigid, 80 mm Ø rigid
and 80 mm Ø exible) made of plastic and expressly conceived
and designed for Immergas condensation boilers.

VICTRIX 24 kW X
Condensation wall-hung boiler for central
heating only which can be connected to a sepa-

VICTRIX 24 kW X
VICTRIX 24 kW X is a wall-hung room-sealed (type C) boiler
with a nominal heating input of 24 kW (20640 kcal/h) for
central heating only and designed, thanks to a kit (optional)
to be connected to a separate Storage tank with an 80, 105,
