Thank you for choosing our boilers.

Please read these installation and maintenance instructions with care.

Please note that the boiler must only be installed, repaired and serviced by qualified personnel.

General information for installers, service engineers and users

This INSTRUCTION MANUAL,

which is an integral and indispen-

sable part of the product, must be

handed over to the user by the

installer and must be kept in a

safe place for future reference. The

manual must accompany the boiler

should it be sold or moved.

This boiler must be used for the

purpose for which it has been

designed. Any other use is con-

sidered incorrect and therefore

dangerous.

The boiler must be installed in com-

pliance with applicable laws and

standards and according to the

manufacturer’s instructions given in

this manual. Incorrect installation

may cause injury or damage, for

which the manufacturer cannot be

held liable.

Damageorinjurycausedbyincorrect

installation or use or failure to obser-

ve the manufacturer’s instructions

shall relieve the Manufacturer of all

liability whether under a contract

or not. Before installing the boiler,

check that the specification meets

the requirements of the system in

which it is to be installed.

Check that the boiler is intact and

that it has not been damaged during

transport and handling.Do not install

equipment which is clearly damaged

or faulty.

Do not obstruct the air intake or heat

dissipation grates.

Only original accessories must be

used for all boilers supplied with

optionals or kits (including electri-

cal ones). All the packaging mate-

rials can be recycled and should be

sent to specific waste management

sites.

Keep the packaging out of the reach

of children as it constitutes a serious

hazard.

In the event of a malfunction, switch

off the boiler immediately. Do not

attempt to make any repairs and

contact a qualified technician.

Original parts must be used for all

repairs to the boiler. Failure to do

this may jeopardize the safety of the

boiler and create a serious hazard.

To guarantee efficiency and cor-

rect operation of the boiler, it is

legally binding to service the boi-

lers once a year according to the

schedule indicated in the relevant

section of this manual.

If the boiler is not used for a certain

length of time, switch off the electri-

city and fuel supply. Place some

calcium carbonate inside the com-

bustion chamber to absorb moisture.

Should there be a risk of freezing,

add anti-freeze. It is not advisable to

empty the system as this may result

in damage. Use a specific anti-free-

ze for multi-metal heating systems.

IMPORTANT

If there is a smell of gas, when

using a gas-fired boiler, always fol-

low these rules.

- Do not operate any electrical

switches or electrical appliances.

- Do not light any flames and do not

smoke.

- Close the main gas tap.

- Open all doors and windows wide.

- Contact a Service Centre, a quali-

fied installer or the gas supply com-

pany.

Never use a flame to detect a gas

leak.

WARNING

This boiler has been built for instal-

lation only in the country indicated

on the rating plate. Installation in

any other country may cause injury

or damage.

open and gas is being supplied,

for example by lighting a gas

ring.

* Press the burner reset button. If

the boiler does not start up after

two attempts, contact an authori-

sed Service Centre or a qualified

technician.

If the burner cuts out frequently,

this means there is a recurring

malfunction, so contact a quali-

fied technician or an authorised

Service Centre.

1.2.3 Shutdown due to overhea-

ting

If red light Dcomes on due to

overheating, it means the safety

thermostat has cut in due to a

recurrent malfunction. Contact an

authorised Service Centre or a

qualified technician.
