HELPFUL SUGGESTIONS

To get the most out of your boiler, we have

provided you with some useful advice on

proper use and maintenance:

- Periodically check the system pressure

using the pressure gauge “J”, make sure

that the pressure is between 1.0 and 1.5

bar (the blue part on the gauge) when the

systemisoff and cool. Consultyour installer

for checking and refilling the system if the

pressure value isunder 1.0 bar.

- The outer panels of the units 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 polishesmust not be

used on the control panel surface or

knobs. Care must be taken in preventing

any liquid entering the appliance.

PRACTICAL TIPS

- If the water is very hard, it is

recommended that a scale reducer be

added to the system so as to reduce the

formation of limescale in the boiler heat

exchanger. This will ensure that the

efficiency of the unit remains the same

over time, reducing gas consumption

Ignition procedure

Push the button “A” the green L.E.D. “B”

will illuminate indicating that the boiler is

supplied with electricity.

Push the button “C” the green L.E.D. “D”

will illuminate indicating that the boiler is

operating for central heating production.

and maintenance costs.

- If the boiler should be out of use for a

prolonged period, it is recommended

that the electrical power supply be

disconnected and that the external gas

cock be closed. If low temperatures are

expected, the boiler and system pipe

work should be drained in order to

prevent frost damage.

- To improve comfort and take full

advantage of the heat produced by the

boiler, it is recommended that an

external (room) thermostat be installed.

- It is good practice to clean and service

the appliance and central heating

system every year.

Call an Authorised Service Centre.

UT013Ab

The centralised electronic control unit will

ignite the burner, without any manual

intervention but in response to the request

for heating. If, after approximately 10

seconds, the burner has not ignited, the

boiler safety devices will shut off the gas

and the red L.E.D. “F” illuminates. To reset

the ignition system, the reset button “E”

must be pressed and released. Should the

boiler fail to ignite a second time, check

that the external gas cock is open. If the

problem persists, contact an Authorised

Service Centre.

Adjusting the heating

It is possible to set the temperature of the

heating system by adjusting the knob “G”

between 1 and 5 until the stop on the

“ECO” position. This will vary temperature

from approximately 40˚C to about 65˚C.

To obtain a higher temperature it is

necessary to turn theEnergy Saving System

(ESS) screw “H” clockwise with a small

coin. The knob is now free to turn to the

MAX position,

which represents

a temperature of

about 80°C.
