VICTRIX PRO 1 I

VICTRIX PRO 1 I is the new range of wall-hung condensing

boilers for room heating only, set-up for independent function-

ing and for cascade conguration (up to 5 appliances), with the

advantage of guaranteeing higher overall output and reduced

running costs. All models can be installed indoors or outdoors

(in the open), on walls or on a new load-bearing frame, oering

exible solutions to professionals who need to size heating con-

trol units based on the buildings. e condensation technology

makes it possible to achieve particularly high outputs. e high

potential of VICTRIX PRO 1 I is ideal for central heating with

large domestic systems (duplexes, three-unit houses, condomin-

iums), as well as commercial and industrial applications, and is

therefore ideal for building energy upgrading.

e new combustion system connected to the boiler's elec-

tronics provides a broader eld of output modulation, between

10% and 100%, therefore streamlining boiler operation, also

through reduced heat load requests (for example during spring

and autumn or when the system is only partially used), which

translates into increased average seasonal output, and therefore

gas consumption savings.

e special ecological burner guarantees particularly reduced

polluting emissions (the boiler belongs to the most environ-

ment-friendly class envisioned by European Standards - class 5).

In case of installation of an individual boiler, and external 3-way

valve can be connected for coupling to a separate storage tank

unit for the production of D.W.H.. A hydraulic manifold can also

be connected in order to increase the circulation in the system

with consequent exibility and speed of installation.

With single or cascade installation, VICTRIX PRO 1 I can be

combined with IMMERGAS solar solutions for the production

of domestic hot water, especially with storage tank units of 200,

300, 500, 1000, 1500 and 2000 litres.

With cascade operation it is possible to hydraulically connect

up to 5 appliances, therefore making it extremely easy to provide

the required output size for the specic heat system.

VICTRIX PRO 1 I can also be installed on a specic modular

supporting frame which oers single or cascade installation

(up to 5 boilers), in linear set-up, or back-to-back for more

limited spaces.

e frame has supporting collars for the hydraulic manifolds

and can be attached to the wall or oor with plugs.

anks to a surface treatment, the frame is also type-approved

for outdoor installation, in the open.

boiler safety devices, code 3.024028.

Immergas S.p.a. declines all liability whenever the installer does

not use approved devices and Immergas original kits or uses

them improperly.

e 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.

For design purposes, by installing the Immergas safety device

kit, the following are already included: Manometer-holder cock,

manometer, thermometer, 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).

e kit is sized for single boiler operation or in combination

with a separate boiler for D.W.H. production. e output of the

boiler in domestic hot water operation must be set based on the

heat exchange output of the coil supplied with the storage tank.

e diverter valve (which is powered by 230 Vac) comes installed

on the ow pipe in combination with a blind manifold (3), re-

ducing the overall installation footprint.

e standard kit comes with a NTC probe which needs to be

applied to the external storage tank unit and connected to the

boiler card (see electrical diagram provided below), removing

any pre-installed temperature probe from the storage tank unit.

Kit installation requires the use of an ON-OFF chrono-thermo-

stat for boiler management.

Note: e boiler has an IPX5D electric insulation rating and

can also be installed outdoors without additional protections.

However, if installed outdoors, the outdoor piping should be

insulated and the kit protected from the elements based on its

electric protection rating.

e hydraulic separator (compensator) is a particularly signif-

icant part inside the hydraulic circuits.

It is an open manifold (2) which places system ow and return

in communication, creating 2 circuits: a primary circuit (boiler

- manifold) and a secondary circuit (manifold-system).

e former circulates by the boiler pump, while the latter runs

on the correct thermal gradient (and therefore the correct water

ow rate), as dened by the system's design.

It is advisable to include a hydraulic compensator (2) every time

the overall ow rate required by the system is greater than what

the boiler is able to supply. e maximum ow rate at the inlet

is the generally adopted sizing method.

The brass sludge collecting filter, with relative inspectable

stainless steel cartridge, protects the condensation module from

getting clogged with the sludge or build-up from the system.

Attention: e boiler has an IPX5D electric insulation rating

and can also be installed outdoors, without additional protec-

tions. However, if installed outdoors, the relevant piping should

be insulated.

is kit is composed of just two gaskets 44x34x2 (1) and two

insulated pipes (2), to compensate for the variation in the centre

distances between ow and return on VICTRIX PRO 35 1 I-55 1

I boilers, which is 300 mm in comparison to the centre distance

between ow and return on the previous range of high output

wall-hung boilers (ex. VICTRIX 50-75), which is 390 mm.

Accordingly, it is possible to install VICTRIX PRO 35 1 I-55

1 I models in place of the models from the previous range of

VICTRIX 50-75 wall-hung boilers in single conguration.

e elements illustrated in the gure and any safety kit for single

boilers must be installed according to the relative documents

of reference.

N.B.: In case of installation outside, the safety devices kit must be

protected using the IPX4D protection box kit for safety devices for

boilers in cascade conguration, code 3.024038.

Immergas declines all liability whenever the installer does not use

original Immergas devices and kits, or uses them improperly.

e 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.

For design purposes, by installing the Immergas safety kit, the

following devices are included: Manometer-holder cock, ma-

nometer, thermometer, 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.

e modular boilers, i.e. installed in cascade (battery) with an Im-

mergas original 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 (ve) modules side-by-side, with a single safety kit.

e hydraulic manifolds (optional) are equipped with non-return

valve positioned on the ow pipe and with system interception cocks

positioned on the ow and return pipes of every boiler (2-way on

return and 3-way on ow).
