SAFETY WARNINGS

CAUTION!

The appliance may only be used by adults after reading the installation and servicing

manual thoroughly.

Children must be supervised to prevent them from playing or tampering with the

appliance

CAUTION!

The appliance must be installed, adjusted and maintained by professionally qualied

personnel, in compliance with the standards and provisions in force. Incorrect instal-

lation can cause damage to persons, animals and objects for which the manufacturer

cannot be held responsible.

DANGER!

NEVER attempt performing maintenance or repairs on the appliance on your own

initiative.

Any work must be done by professionally qualied personnel. We recommend stip-

ulating a maintenance contract.

Insufcient or irregular maintenance can jeopardise the operating safety of the appli-

ance and cause damage to persons, animals and objects for which the manufacturer

cannot be held responsible.

ATTENTION!

Changes to the parts connected to the boiler (once the boiler installation is complete)

Do not modify the following parts:

- the boiler

- the gas, air, water and electricity supply lines

- the ue gas pipe, the safety valve and the exhaust pipe

- the construction parts which affect the operating safety of the appliance.

ATTENTION!

To tighten or loosen the screwed ttings, use only appropriate xed spanners.

Non-compliant use and/or inappropriate tools can cause damage (e.g. water or gas

leakage).

ATTENTION!

Indications for propane gas-red appliances

Make sure that the gas tank has been deaerated before installing the appliance.

For state-of-the-art tank venting, contact the LPG supplier or person qualied in

compliance with the law requirement.

If the tank has not been professionally deaerated, ignition problems could arise.

In that case, contact the supplier of the LPG tank.

DANGER! Smell of gas

Should a smell of gas be perceived, follow these safety guidelines:

- do not turn electric switches on or off

- do not smoke

- do not use the telephone

- close the gas shut-off valve

- air out the area where the gas leakage has occurred

- inform the gas supplier or a company specialised in installation and maintenance

of heating systems.

DANGER! Explosive and easily ammable substances

Do not use or store explosive or easily ammable materials (e.g. petrol, paints, paper)

in the room where the appliance is installed.

DANGER!

Do not use the appliance as a supporting base for objects.

In particular, do not place receptacles containing liquids (Bottles, Glasses, Jars or

Detergents) on top of the appliance.

If the appliance is installed inside a housing, do not insert or rest other objects inside

this housing.

The boiler has been built according to the current level of engineering and acknowledged

technical safety rules.

Nonetheless, if improperly used, dangers could arise for the safety and life of the user and

other persons or damage to the equipment or other objects.

The appliance is designed to work in heating systems, with hot water circulation, for the pro-

duction of domestic hot water.

Any other use is considered improper.

UNICAL AG S.p.A. will not be held liable for any damage resulting from improper use.

Use according to the intended purposes also includes strict compliance with the instructions

in this manual.

The user must be instructed concerning the use and operation of the heating system, in particular:

• Delivertheseinstructionstotheuser,aswellasotherdocumentsconcerningtheappliance

inserted in the envelope inside the packaging. The user must keep this documentation safe

for future consultation.

• Informtheuserabouttheimportanceoftheairventsandtheuegasexhaustsystem,high-

lighting their essential features and the absolute prohibition of modifying them.

• Informtheuserconcerningcontrollingthesystem'swaterpressureaswellasoperationsto

• Informtheuserconcerningcorrecttemperaturecontrol,controlunits/thermostatsandradiators

for saving energy.

• Rememberthatthesystemmustreceiveregularmaintenanceatleastonceayearandcom-

bustion analysis must be performed every two years (as per national law).

• Shouldtheappliancebesoldortransferredtoanewownerorifyoumoveandleavethe

appliance, always make sure that the instruction booklet accompanies it in order to be con-

sultedbythenewownerand/orinstaller.

The manufacturer will not be held liable in the event of damage to persons, animals or objects

resulting from failure to comply with the instructions contained in this manual.
