CAUTION

Installation, start-up, adjustments and maintenance must be

performed by a competent person only, in accordance with the

current Gas Safety (Installation & Use) Regulations and the

instructions provided. Improper installation may cause damage or

injury to individuals, animals and personal property, for which the

To ensure efficient and safe operation it is recommended that the

boiler is serviced annually by a competent person.

If it is known or suspected that a fault exists on the appliance, it

must not be used until the fault has been corrected by a competent

person.

HELPFUL SUGGESTIONS

To get the most out of your boiler, we have provided you with some

useful advice on the proper use and maintenance:

- Periodically check the system pressure using the pressure guage

“O”, make sure that the pressure at 1.5 bar (the blue part on the

gauge) when the system is off and cool. The warning L.E.D. “D” will

indicate if the pressure is below the minimum recommended value.

Consult your installer for checking and refilling the system.

- The outer panels of the unit's case must only be cleaned with a damp

cloth. Do not use abrasive cleaners.The Control panel can be wiped

with either a damp or dry cloth. Spray polishes must not be used on

the control panel surface or knobs. Care must be taken in preventing

any liquid entering the appliance.

- If the water is exceptionally hard, install a water softener so that the

efficiency of the unit remains the same over time, as this will consume

less gas.

- To improve comfort and take full advantage of the heat produced by

the boiler, it is recommended that an external thermostat be installed.

- If the boiler is not going to be used for an extended period of time, turn

off the supply of electricity to the unit by pressing the On/Off switch

“L”.

- The green L.E.D.“I”will turn off.Then turn off the supply of gas to the

unit itself.

- It is good practice to clean and service the appliance and central

heating system every year.

- Call an Authorised Service Centre.

2. OPERATING

INSTRUCTIONS

START-UP PROCEDURE LIGHTING

Before starting the unit, check the following:

· The water pressure on the pressure gauge “O”;

· That the gas cock and the inlet for domestic water are

open.

These models are equipped with electronic ignition which utilises

contact ionisation.

To make the boiler operational, simply press the On/Off switch “L”.

The green L.E.D. “I” will then turn on.

At this point the boiler is ready for use: a centralised electronic control

unit will automatically light the main burner when needed. If the burner

does not light within the pre-set safety time limit, the red “B” L.E.D.will

light up. To reset the ignition system, the reset button “A” must be

pressed. Should the system fail to light a second time, check to make

sure that the gas cock is open. If the problem persists, contact one of

our Authorised Service Centres for assistance.

WINTER AND SUMMER OPERATING MODES

The boiler is fitted with a selector knob “C” which allows you to switch

between winter <>and summer <>and also heating only <

> operating modes and vice versa.When the knob is set to <

>, the boiler can serve the dual purpose of providing heat and/or hot

water for domestic use.

The supply of hot water for domestic use always takes precedence

over heating. When the knob is set to <>,the boiler cuts out the

heating system and only provides hot water for domestic use (when

needed).

TURNING ON THE CENTRAL HEATING

Installation without a room thermostat :

- Turn on the power supply to the boiler by pressing the

On/Off switch “L”; the green L.E.D. “I” will then turn on;

- Turn the “C” selector knob to <>or < > (in this position no

domestic hot water is produced);

- Regulate the temperature of the water in the boiler by turning the “H”

knob. The temperature can vary between 42°C and about 82°C;

- Check the boiler temperature on the thermometer with the yellow

L.E.D.s “F”. With this type of installation, the ambient temperature

does not influence the operation of the boiler and the circulation

pump always remains in operation.

UT008Ab

UT008Ac

403

Installation with a room thermostat:

- Turn the “C” selector knob to < >;

- Turn on the power supply to the boiler by pressing the On/Off switch

”L”; the green L.E.D. will then turn on;

- Turn the thermostat knob “H” to the highest temperature setting.

- With this type of installation, the boiler is controlled by a room

thermostat

. Therefore, it runs until the ambient temperature has reached the

temperature setting on the thermostat. At that point, the main burner

will turn off and the circulation pump will stop.

TURNING OFF THE CENTRAL HEATING

Installation without a room thermostat:

To turn off the heating, turn the “C” selector knob to < >.The boiler

will still provide hot water for domestic use.

ADJUSTING THE HEATING TEMPERATURE

To economise on consumption while achieving the highest level of

comfort, the temperature adjustment knob is designed with three

different heating zones based on the temperature outside the home.

Rotate the knob “H” as shown below.

PRODUCTION OF HOT WATER

FOR DOMESTIC USE

- Turn on the power to the boiler by pressing the On/Off switch “L”;

- Turn the “C” selector knob to <>or < > (in this position no

central heating is produced);

- Turn the “E” knob to select the temperature for the hot water

(between 40°C and about 70°C).

ADJUSTING THE TEMPERATURE OF

WATER FOR DOMESTIC USE

It is recommended that the temperature for the hot water should not be

set to high temperatures and then mixed with cold water. Setting the

thermostat to medium temperatures is preferable

4. USEFUL INFORMATION

AND TROUBLESHOOTING

BOILER SHUTDOWN

The boiler unit is equipped with safety devices which intervene in

certain situations to shutdown the boiler.

Some of these situations are signalled by the unit and can be corrected

by the user.

SHUTDOWN DUE TO THE FAILURE OF THE

BURNERTO LIGHT AUTOMATICALLY

This anomaly is indicated by the red “B”L.E.D.

To reset the unit, press and then release the “A”button.

At this point, the electronic ignition system will attempt to light the

burner again.

If lighting failure occurs repeatedly, it is recommended that you contact

one of our Authorised Service Centres.

SHUTDOWN DUE TO OVERHEATING

This anomaly is signalled by the red “G”L.E.D.

The boiler shuts off because the safety thermostat detected that the

boiler temperature has reached the temperature limit.

To reset the unit, wait until the boiler has cooled and then press the “A”

button.

If the safety thermostat shuts off the unit on a frequent basis, contact

one of our Authorised Service Centres for assistance.

SHUTDOWN DUE TO INSUFFICIENT

WATER CIRCULATION

This anomaly is indicated by the red “D”L.E.D.

One of the possible causes of this shutdown situation could be the lack

of water in the boiler or water circulation failure in the primary heating

circuit.

Check the system pressure on the pressure gauge “O”and, if it is less

than 0.5 bar, consult your installer for checking and refilling the system.

Then reset the unit by turning the boiler off and then back on with the

On/Off button “L”.

If this situation persists, contact one of our Authorised Service Centres.
