SAFETY

The aluminium boilers in the range Multidea Evo are condensing heat generators, designed to heat rooms, and in
combination with a storage tank, for the production of domestic hot water.
They comprise:
- a steel heat exchanger, with low water content and generously sized exchange surface to optimise energy efficiency and
heating output;
- a full pre-mix microflame burner in stainless steel, to guarantee high modulation ratios, combustion stability and low
pollutant emissions (NOx Class = 5);
- a variable speed blower, required for air/gas modulation and mixing;
- a combustion circuit, which can be “type C” (room-sealed) or “type B” (open-flued), with respect to the installation
environment, and on the basis of the flue exhaust configuration on site;
- command-control electronics, which if equipped with outside sensor enables adjustment of the supply temperature on
the basis of the outside temperature. The appliance thus only provides the heat effectively needed by the utility, avoiding
energy waste. The unit is fitted with self-diagnostics with a display of the error codes and operating parameters at the
time of the fault, thereby simplifying tasks for the Technical Services department.
Also, during periods of prolonged disuse or holidays, the appliance remains protected by the Anti-freeze Function, which is
activated automatically when the supply temperature falls to 5°C and shuts off when it returns to 15°C. Obviously the gas
and electrical mains supplies must be active during these periods.
The design phase adopted specific solutions to:
- obtain a constantly optimal air/gas mix;
- minimise dispersions;
- reduce noise levels to a minimum.
The Multidea Evo boilers are designed for connection to 0-10 V DC controls and for operation in cascade, in sets of up
to 6 units, and can be equipped with various system accessories, such as the mix bottle or water shut-off valve, and the
INAIL unit, which all simplify the work of the installer and comply with compulsory italian legal requirements.
DESCRIPTION
Multidea Evo appliances are equipped with the following safety, control and adjustment devices:
- Sensor on the appliance heat exchanger, to ensure thermal cut-out when the temperature reading exceeds the maximum
admissible value. This is reset manually via the DSP keypad.
- Water pressure sensor: this intervenes when the hydraulic circuit pressure falls below 0.8 bar.
- Flue safety sensor: this intervenes when the flue temperature is too high.
- Hydraulic circuit diagnostics to protect the boiler against:
 - temperatureoverload,bycheckingthedifferenceintemperaturesonsupplyandreturn(ΔT);
- inadequate water circulation in the heat exchanger, checking the difference in temperatures between the heat
exchanger sensor and supply sensor.
bWARNING
•If a safety devices trips, this means that there is a potentially hazardous appliance malfunction. In this case contact
Technical Services as soon as possible for assistance.

HANDLING
After removing the packaging, the appliance can be
handled manually by tilting it and lifting it from the points
indicated in the figure.
b Never use the boiler casing as a lifting point;
always use "solid" parts such as the base or
rear structure.
b ALWAYS use suitable accident protection equip-
ment.
a It is strictly prohibited to dispose of packaging into
the environment or leave in the reach of children as
this constitutes a potential source of danger. It must
therefore be disposed of in accordance with current
legislation in the place of use.
INSTALLATION ROOM
The installation room must always comply with current
technical standards and legislation in the country of use.
The room must be fitted with suitably sized ventilation
outlets in the case of "TYPE B23P" installations.
The installation room must exclusively be for this
purpose and comply with current technical standards and
legislation in the country of use.
MULTIDEA EVO appliances may also be installed
outdoors, under a canopy, i.e. with adequate protection
from atmospheric agents.
INDICATIVE SAFETY ZONES
bWARNINGS
•Take into account the clearances required for
accessibility to the safety/adjustment devices and for
maintenance purposes.

INSTALLATION

When the appliance is installed on systems that are old or to be updated, ensure that:
- The flue duct, if re-used, is suitable for the new condensing boiler, and that it is calculated and constructed in compliance
with current standards, as straight as possible, airtight, insulated and free of any obstructions or narrowed sections.
- The flue is fitted with an outlet for removal of condensate.
- The electrical system complies with the relevant standards and is set up by professionally qualified personnel.
- The fuel intake line and tank (if fitted) is produced according to the specific standards and is fitted with a gas meter.
- The expansion vessel ensures total absorption of fluid expansion in the system.
- The system is washed, removing all sludge and deposits and that all hydraulic seals are efficient.
- A supply water treatment/replenishment system is fitted, as described in the next chapter.
- Efficient systems are fitted for the elimination of air and impurities up to 5 μm (e.g. Y filters, micro-impurity
separators and micro air bubble separators).
- if an automatic filling system is fitted, a litre counter is installed in order for a precise check on the entity of any leaks.
- Water must never be drained from the system during routine maintenance, even in apparently insignificant quantities. For
example when cleaning filters, ensure that the system has specific shut-off valves for this purpose.
bWARNINGS
The manufacturer declines all liability for possible damage caused by incorrect installation or design of the
flue or constant replenishment of the boiler water.
Before installing the appliance, thoroughly clean all pipelines and heating elements.
PROPERTIES OF WATER TO BE USED WHEN FILLING THE SYSTEM
The following type of water must be used to fill the system:
pH : from 6.5 to 9
Ca+++ Mg++ : less than 0.5°f
OH-+ 1/2 Ca3- : from 5 to 15°f
P2O5 : from 10 to 30 mg/l
Na2SO3 : from 20 to 50 mg/l
If the system water also comes into contact with aluminium, a pH factor of less than 8.5 is required.
If the analysis of a sample of the water to be used for filling the system shows values other than those above, a suitable
inhibitor must be used. This will prevent the formation of scale, which could impair correct operation of the boiler unit.
In the case of systems at low temperatures only, a product must be used to inhibit the spread of bacteria.
Water treatment in civil heating systems: see standard UNI 8065 of 1989.
REPAIRS AND PARTS REPLACED DUE TO THE FORMATION OF SCALE ARE NOT COVERED BY THE WARRANTY.
CAUTION: both on new systems or replacements, the system must be fitted with efficient systems that eliminate the air
andimpuritiesupto5μm(e.g.Yfilters,microimpurityseparatorsandmicroairbubbleseparators).

bWARNINGS
•Never soften water using the ion exchange principle.
•Never fill the system using distilled or demineralised water, as these cause serious corrosion of the heat exchanger. The
system must be filled and replenished with softened water to reduce overall hardness. The water must also be treated
to maintain the pH factor within the envisaged range, to avoid the risk of corrosion.
•On a register, note the quantity of filling water, top-up water, water quality readings and water treatment used.
•Install a meter to control the quantity of filling and top-up water.
•The conductivity of the untreated water in the system must NEVER exceed 600 µs/cm.
•If the system water is treated, strictly observe the instructions of the manufacturer of the product used, and ensure that
conductivity NEVER exceeds 2000 µs/cm.
•Intheeventofgeneratorreplacement,itisCOMPULSORYtowashtheentiresystem.
NOTE: If conductivity exceeds the values specified above, drain the system, flush it and fill with clean and treated tap water.
bWARNINGS
•The boiler is delivered with a check valve as part of
the standard supply. Ensure that the check valve is
inserted in the return connection (RI) only in the case
of cascade configurations.

bWARNINGS
•Fill the condensate drain syphon (2) to a sufficient level and route the condensate drain hose correctly. Envisage suitable
condensate treatment systems.
•The safety valve drain must be connected to a suitable disposal system. The manufacturer is not responsible for
possible flooding caused by intervention of the safety valve.
•Systems charged with anti-freeze require the compulsory use of water shut-off devices.
•The selection and installation of the system components is the task of the installer, who must observe all current
legislation and professional technical practices.
•The expansion vessel of the heating circuit must ensure total absorption of the fluid expansion in the system.
