VICTRIX X 12 2 I

Wall-hung, sealed, condensing boiler for cen-

tral heating only, can be coupled to a separates 

Storage tank unit.

VICTRIX X 12 2 I

VICTRIX X 12 2 I is a wall-hung sealed boiler (type C) with 

useful heat output of 12 kW (10,320 kcal/h) for central heating 

only, prepared thanks to a relevant kit (

optional

),  for coupling 

to a separate 80, 105, 120, 200 litre Storage tank unit.

Thanks to condensing technology, the boiler distinguishes itself 

due to its high efficiency and large field of modulation (

from 

15 % to 100 % of the nominal heat output

).

The boiler has a total premix combustion system that gua-

rantees particularly reduced pollutant emissions and allows 

functioning with natural gas or LPG.

The VICTRIX X 12 2 I range are type-approved for installation 

outside the building in a partially protected place.

N.B.: 

A partially protected location is one in which the appliance 

is not exposed to the direct action of the weather (rain, snow, 

hail, etc..

).

They are also characterised for the assembly inside a relevant 

universal  frame  (

Omni  Container

)  with  small  dimensions 

(H=1190 x L=566 x D=254), which allows it to be housed in 

the walls of the home.

Adjustment and control of the appliance are entrusted to a 

P.C.B. with micro processor with continuous flame modu-

lation, which using a back-lit display shows the boiler fun-

ctioning  status  (

temperatures,  safety  devices,  etc.

)  and  allows 

connection (

optional

) to the Comando Amico Remoto remote 

control, which allows to easily manage and control the boiler 

at a distance, the external probe, the zone control unit and the 

DIM 

(multi-system distribution manifold).

The boiler uses a new condensation module; 

its inside part is 

  General features.

realised in a stainless steel coil shape and makes up the sealed 

combustion chamber and the condensation chamber, while 

the external part (

casing

) is made in composite material and 

also encloses the flue hood.

As  well  as  the  new  condensation  model

  (

water  gas  heat 

exchanger

the hydraulic circuit is also made up from the 

hydraulic unit in composite material

.

Along with the pump, this unit houses the electric 3-way valve 

and the hydraulic circuit control devices (

3 bar safety valve, 

automatic system by-pass, etc..

.).

A system flow switch controlling the correct circulation of water 

in the boiler allows the activation of the boiler every time there 

is a central heating or anti-freeze request.

The boiler has 

anti-freeze safety device as per standard

 that 

protects it to a minimum temperature of 

-

5°C

 (optional to 

-15°C).

The VICTRIX X 12 2 I boiler must be installed using the 

intake/exhaust kits or the ducting systems (

Ø 60 mm rigid, 

Ø 80 mm rigid and Ø 80 mm flexible

) realised in plastic and 

designed expressly for Immergas condensing boilers.
