SAFETY WARNINGS AND REGULATIONS
· After unpacking the appliance, ensure that all parts are intact and complete as per the supply specifications, and if any
non-conformities are found, contact the Representative that sold the appliance.
· The appliance must be installed by professionally qualified personnel, in conformity with current national and local
standards and the instructions in the manual supplied with the product.
· The appliance must only be used as envisaged in the design. The manufacturer declines all liability for physical injury
or damage to animals or objects caused by errors in installation, adjustments, maintenance or improper use of the appliance.
· In the event of water leakage, disconnect the appliance from the electric power mains, shut off the water supply and
promptly notify the Technical Services department or other professionally qualified personnel.
· Periodically check that the hydraulic system operating pressure, in cool conditions, is approx. 2 bar. Otherwise contact
the Technical Services department or other professionally qualified personnel.
· In the event of prolonged disuse of the appliance, the following procedure must be observed:
– Set the appliance switch H and the main system switch to “OFF”. – Shut off the fuel and mains water valves.
· This manual is an integral part of the appliance and consequently must ALWAYS accompany the appliance, also in the
event of sale to another Owner or User or transfer to another system. The manual must be kept with care and in the event of damage or loss, another copy may be requested from the Technical Services department.
· It is recommended to service the appliance at least once a year.
Pursuant to Directive 2012/19 / EU on waste electrical and electronic equipment (WEEE) “the crossed bin symbol on the appliance and on the packaging indicates that the gas boiler, at the time of its disposal, must be collected and disposed separately from other waste (see section End of life disposal).

DESCRIPTION
The aluminium boilers in the range MULTIPARVA 3.0 F 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 = 6); – 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 MULTIPARVA 3.0 F 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.
The MULTIPARVA 3.0 F boilers are equipped with 5 litres expansion vessel, safety drain valve and water pump. The MULTIPARVA 3.0 N boilers are without expansion vessel, safety drain valve and water pump.
DEVICES
MULTIPARVA 3.0 F 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 0.5 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 (T); – inadequate water circulation in the heat exchanger, checking the difference in temperatures between the heat
exchanger sensor and supply sensor. – Siphon pressure switch that turn off the burner when the pressure inside the combustion chamber overcome 700 Pa. – Air Pressure Switch (APS) (Only 150kW model) which checks the correct working of the combustion circuit before the
starting of the boiler.
b WARNING
· 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.

SCHEDULER SETTINGS
The system also envisages the option of setting time bands during which the boiler is set to operate, if there is a demand for heat, and those during which it remains off, or in ECO mode when fitted with an outside sensor. There is a maximum of 6 programmable time bands within 24 hours, each of which must be identified by a start time (ON), and end time (OFF). The minimum interval between each time is half an hour.
