Installation, start-up, adjustments and maintenance must be

performed by a competent person only in accordance with the Gas

Safety (Installation & Use) Regulations (1984) and the instructions

provided. Improper installation may cause damage or injury to

individuals, animals and personal property, for which the

manufacturer will not be held liable.

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 exits on the appliance, it must

not be used until 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 pres-

sure guage “O”, make sure that the pressure is

between 1.0 and 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 effi-

ciency 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.

WINTER AND SUMMER OPERATING MODES

(FOR ALL MODELS)

The boiler is fitted with a selector knob “C” which

allows you to switch between winter <>and

summer <>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).

B003

START-UP PROCEDURE

LIGHTING

(FOR ALL MODELS )

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.

TURNING ON THE BOILER

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 <>;

- 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 re-

mains in

operation.

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 tempera-

ture setting.

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

Therefore, it runs until the ambient temperature has reached the tempe-

rature setting on the thermostat.At that point, the main burner will turn off

and the circulation pump will stop.

TURNING OFF THE BOILER

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.

B003

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

(FOR ALL MODELS)

- Turn on the power to the boiler by pressing the

On/Off switch “L”;

- With these settings, the boiler is already ready for use,

regardless of the position of the “C” selector knob.

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

36°C and about 56°C depending on the flow rate of the water).

ADJUSTING THE TEMPERATURE OF

WATER FOR DOMESTIC USE

(FOR ALL MODELS)

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
