Š CHECK FOR THE PRESENCE OF ANY OBSTRUCTIONS BEFORE SWITCHING THE APPLIANCE ON FOLLOWING
A PROLONGED PERIOD OF INACTIVITY.
Š THE GENERATOR HAS BEEN DESIGNED TO FUNCTION IN ANY CLIMATIC CONDITION. IN PARTICULARLY
ADVERSE CONDITIONS (STRONG WIND, FREEZING) SAFETY SYSTEMS MAY INTERVENE THAT SWITCH THE
GENERATOR OFF. IF THIS OCCURS, CONTACT THE TECHNICAL AFTER-SALES SERVICE AND ALWAYS DISABLE
THE SAFETY SYSTEMS.
Š IN THE EVENT THE FLUE CATCHES FIRE, USE SUITABLE SYSTEMS FOR SUFFOCATING THE FLAMES OR
REQUEST HELP FROM THE FIRE BRIGADE.
Š THIS APPLIANCE MUST NOT BE USED TO BURN WASTE
Š DO NOT USE ANY FLAMMABLE LIQUIDS FOR IGNITION

pUrposE of UsE

The ecological water-cooled boilers are structured to heat homes, chalets, country houses and other similar buildings. The boilers are suitable
to heat buildings having heat dispersion between 15 and 40 kW. The recommended type of combustion is dry wood having a diameter of
80 – 150 mm and log length of 500 mm. The boiler is not built to burn sawdust or small scraps of wood. These can only be used in minimum
amounts (maximum 10%) together with larger pieces of wood.

IMporTANT rULEs for CorrECT opErATIoN AND DUrATIoN of THE boILEr.

Boiler installation and testing must be carried out by an authorised company, which must also complete the INSTALLATION
DECLARATION OF THE BOILER, as requested by the standard in force in this regard, UNI 10683.
1. fuel tar and condensation (acids) can develop inside the combustion chamber. Therefore, in order to maintain minimum water return
temperature in the boiler (60°) and prevent deposit of the aforesaid harmful elements, you must install an anti-condensation mixing
valve at 60°C, or an adequate anti-condensation system.
1. When the system has reduced absorption (for example, for summer production of domestic water), the boiler must be switched on when
required, loading the amount of wood strictly necessary to fulfil the request. You must then leave it to extinguish.
2. We recommend you install the boiler with storage tanks and a thermostatic mixing valve at 60°C, which guarantee fuel savings of 20-30%,
a longer duration of the boiler and the flue, as well as more comfortable management.
3. The wood used must contain a moisture percentage below 15-20%. A higher moisture percentage reduces the boiler's power and
increases consumption. A lower percentage generates irregular gas distribution, which makes it more or less impossible to
control.
ATTENTIoN – Failure to comply with the essential rules of installation and use significantly shortens the life-span of the boiler's
structure and ceramic profiles as a result of the effect of low temperature corrosion. The boiler's structure can be subject to the
effects of corrosion even within 2 years.

MANAgEMENT AND MoNITorINg

• It is forbidden to leave children unattended next to the boiler when in operation.
• It is forbidden to use flammable liquids to ignite the boiler with solid fuel. Also, during operation, it is forbidden to increase the nominal
power (overheating) in any way.
• It is forbidden to throw flammable objects into the boiler or next to the infeed opening and ash drawers, and it is compulsory to
only empty the ashes in non-flammable containers equipped with a cover.
• The boilers must be supervised by the operator from time to time during operation.
• During operation, check the seal of the doors and the cleaning openings, which must always be secured well.
• The user is not authorised to intervene on the structure and electrical system of the boilers.
• The boiler must always be perfectly clean in a timely manner in order to ensure good flow of all draughts.
• The infeed doors and ash drawer must always be closed properly.
According to Italian Legislative Decree 412/93 and subsequent updates, the people in charge of the system are different and are characterised
according to the system's power.
