THE USER WILL FIND FURTHER INFORMATIONS ABOUT OPERATING AND USE RESTRICTIONS, IN THE SECOND SECTION OF THIS MANUAL. WE HIGHLY COMMEND TO READ IT.

CAREFULLY KEEP THIS MANUAL FOR FUTURE REFERENCE.

1) GENERAL INTRODUCTION

The equipment must be installed in compliance with the regulations in force, following the manufacturer’s instructions, by qualified personnel.

Qualified personnel means those having technical knowledge in the field of components for civil or industrial heating systems, sanitary hot water generation and particularly service centres authorised by the manufacturer.

Improper installation may cause injury to people and animals, or damage to property, for which the manufacturer cannot be held liable.

* Remove all packaging material and inspect the equipment for integrity.

In case of any doubt, do not use the unit - contact the supplier.

The packaging materials (wooden crate, nails, fastening devices, plastic bags, foamed polystyrene, etc), should not be left within the reach of children, as they may prove harmful.

*Before any cleaning or servicing operation, disconnect the unit from the mains by turning the master switch OFF, and/or through the cut-outdevices that are provided.

*Make sure that inlet or exhaust grilles are unobstructed.

*In case of breakdown and/or defective unit operation, disconnect the unit. Make no attempt to repair the unit or take any direct action.

Contact qualified personnel only.

Units shall be repaired exclusively by a servicing centre, duly authorised by the manufacturer, with original spare parts.

Failure to comply with the above instructions is likely to impair the unit’s safety.

To ensure equipment efficiency and proper operation, it is essential that maintenance operations are performed by qualified personnel at regular intervals, following the manufacturer’s instructions.

*When a decision is made to discontinue the use of the equipment, those parts likely to constitute sources of danger shall be made harmless.

*In case the equipment is to be sold or transferred to another user, or in case the original user should move and leave the unit behind, make sure that these instructions accompany the equipment at all times so that they can be consulted by the new owner and/or the installer.

*For all the units that have been modified or have options fitted then original accessory equipment only shall be used.

*This unit shall be employed exclusively for the use for which it is meant. Any other use shall be considered as improper and, therefore, dangerous.

The manufacturer shall not be held liable, by agreement or otherwise, for damages resulting from improper installation, use and failure to comply with the instructions supplied by the manufacturer.

2) SPECIAL INSTRUCTIONS FOR BURNERS

*The burner should be installed in a suitable room, with ventilation openings complying with the requirements of the regulations in force, and sufficient for good combustion.

*Only burners designed according to the regulations in force should be used.

*This burner should be employed exclusively for the use for which it was designed.

*Before connecting the burner, make sure that the unit rating is the same as delivery mains (electricity, gas oil, or other fuel).

*Observe caution with hot burner components. These are, usually, near to the flame and the fuel pre-heatingsystem, they become hot during the unit operation and will remain hot for some time after the burner has stopped.

* When the decision is made to discontinue the use of the burner, the user shall have qualified personnel carry out the following operations:

a)Remove the power supply by disconnecting the power cord from the mains.

b)Disconnect the fuel supply by means of the hand-operatedshut-offvalve and remove the control handwheels from their spindles.

Special warnings

*Make sure that the burner has, on installation, been firmly secured to the appliance, so that the flame is generated inside the appliance firebox.

*Before the burner is started and, thereafter, at least once a year, have qualified personnel perform the following operations:

a)set the burner fuel flow rate depending on the heat input of the appliance;

b)set the flow rate of the combustion-supportingair to obtain a combustion efficiency level at least equal to the lower level required by the regulations in force;

c)check the unit operation for proper combustion, to avoid any harmful or polluting unburnt gases in excess of the limits permitted by the regulations in force;

d)make sure that control and safety devices are operating properly;

e)make sure that exhaust ducts intended to discharge the products of combustion are operating properly;

f)on completion of setting and adjustment operations, make sure that all mechanical locking devices of controls have been duly tightened;

g)make sure that a copy of the burner use and maintenance instructions is available in the boiler room.

*In case of repeated burner shut-downs,do not continue resetting the unit manually. Contact qualified personnel to take care of such defects.

*The unit shall be operated and serviced by qualified personnel only, in compliance with the regulations in force.

3) GENERAL INSTRUCTIONS DEPENDING ON FUEL USED

3A) ELECTRICAL CONNECTION

*For safety reasons the unit must be efficiently earthed and installed as required by current safety regulations.

*It is vital that all saftey requirements are met. In case of any doubt, ask for an accurate inspection of electrics by qualified personnel, since the manufacturer cannot be held liable for damages that may be caused by failure to correctly earth the equipment.

*Qualified personnel must inspect the system to make sure that it is adequate to take the maximum power used by the equipment shown on the equipment rating plate. In particular, make sure that the system cable cross section is adequate for the power absorbed by the unit.

*No adaptors, multiple outlet sockets and/or extension cables are permitted to connect the unit to the electric mains.

An omnipolar switch shall be provided for connection to mains, as required by the current safety regulations.

The use of any power-operatedcomponent implies observance of a few basic rules, for example:

-do not touch the unit with wet or damp parts of the body and/ or with bare feet;

-do not pull electric cables;

-do not leave the equipment exposed to weather (rain, sun, etc.) unless expressly required to do so;

-do not allow children or inexperienced persons to use equipment;

* The unit input cable shall not be replaced by the user.

In case of damage to the cable, switch off the unit and contact qualified personnel to replace.

* When the unit is out of use for some time the electric switch supplying all the power-drivencomponents in the system (i.e. pumps, burner, etc.) should be switched off.

3B) FIRING WITH GAS, GASOIL OR OTHER FUELS

GENERAL

*The burner shall be installed by qualified personnel and in compliance with regulations and provisions in force; wrong installation can cause injuries to people and animals, or damage to property, for which the manufacturer cannot be held liable.

*Before installation, it is recommended that all the fuel supply system pipes be carefully cleaned inside, to remove foreign matter that might impair the burner operation.

*Before the burner is commissioned, qualified personnel should inspect the following:

a)the fuel supply system, for proper sealing;

b)the fuel flow rate, to make sure that it has been set based on the firing rate required of the burner;

c)the burner firing system, to make sure that it is supplied for the designed fuel type;

d)the fuel supply pressure, to make sure that it is included in the range shown on the rating plate;

e)the fuel supply system, to make sure that the system dimensions are adequate to the burner firing rate, and that the system is equipped with all the safety and control devices required by the regulations in force.

* When the burner is to remain idle for some time, the fuel supply tap or taps should be closed.

SPECIAL INSTRUCTIONS FOR USING GAS

* Have qualified personnel inspect the installation to ensure that:

a)the gas delivery line and train are in compliance with the regulations and provisions in force;

b)all gas connections are tight;

c)the boiler room ventilation openings are such that they ensure the air supply flow required by the current regulations, and in any case are sufficient for proper combustion.

*Do not use gas pipes to earth electrical equipment.

*Never leave the burner connected when not in use. Always shut the gas valve off.

*In case of prolonged absence of the user, the main gas delivery valve to the burner should be shut off.

Precautions if you can smell gas

a)do not operate electric switches, the telephone, or any other item likely to generate sparks;

b)immediately open doors and windows to create an air flow to purge the room;

c)close the gas valves;

d)contact qualified personnel.

* Do not obstruct the ventilation openings of the room where gas appliances are installed, to avoid dangerous conditions such as the development of toxic or explosive mixtures.

SETTINGS

Burners G18SP - PG25SP

These burners are fitted with a double-regulationpump. The flame control device, atwin-stageone, after thepre-purguestage, energized the valve EV1 and the burner starts up.

After few seconds, the intervention of the second stage caused the energizing of the valve EV2, so the burner is feeded with a maximum pressure of about 18 bar.

Burner PG30TN

Before carry out the settings, start-upthe light oil pump proceeding as follows:

- start up the burner, light the photoresistor after the solenoid valve opening and leak the air from the manometer gauge. Before starting up the burner, be sure that the return pipe to the tank is not obstructed; any obstruction would cause the pump seal to break.

Light oil flow rate setting

The light oil rate is adjusted by chosing a nozzle with appropriate dimensions and setting the inlet pump pressure; to chose the nozzle, refer to the tables below.

LIGHT OIL PUMP SETTINGS

Burners G18SP - PG25SP

Adjust the pump for the ingnition, to a pressure value of about 8-10bar (see fig. 7).

After 10”, the safety device drives the second stage; set the pump to a pressure value of 18 bar, by means of the regulation screw.

Burner PG30TN

Set the pump to a pressure value from 10 to 14 bar, depending by the nozzle fitted (see table 2).

COMBUSTION HEAD ADJUSTMENT

Burner G18SP

Loose the screw VBS and rotate the air damper in the desired position, to set the air flow.

At the end of settings, tight the screw VBS.

Burners PG25SP - PG30TN

Loose the screw VBS and set the air flow, working directly on the air damper.

At the end of settings, tight the screw VBS.

The burner is factory-adjustedwith the combustion head in the “max” position (maximum output). Move back the combustion head towards the “MIN” position, turning the screw VRT clockwise.
