5. During the first starts, no object should be leaned on the appliance and in detail on enamelled surfaces. Enamelled surfaces must
not be touched during heating.
6. Once the «break-in» has been completed, it is possible to use the product as the motor of a car, avoiding abrupt heating with
excessive loads.
After testing the proper working of the appliance, some days from the installation, it is possible to proceed with
the construction of its aesthetic covering.
WARNING: During the surround building operations it must kept in mind possible and subsequent electrical installed parts
maintenance (Fans, temperature probe, etc) and with hydraulic systems all parts connected to the thermo-fireplace.

LOW EMISSION fire lighting

Smokeless combustion is a way of lighting a fire able to significantly reduce the emission of harmful substances. The wood burns
gradually from the top downwards, so combustion is slower and more controlled. Burnt gases pass through the high temperatures of
the flame and therefore burn almost completely.
Place the logs in the hearth a certain distance apart as shown in the
at the top, or vertically in the case of tall narrow combustion chambers. Place the fire starter module on top of the pile, arranging the
first logs in the module at right angles to the pile of wood.
Fire STARTER MODULE. This fire starter module replaces a paper or cardboard starter. Prepare four logs, 20 cm long with a cross
section of 3 cm by 3 cm Picture
(wax impregnated wood fibre for example) in the middle. The fire can be lit with a match. If you want, you can use thinner pieces of
wood. In this case, you will need a larger quantity. Keep the flue gas exhaust valve and combustion air regulator open.
After lighting the fire, leave the combustion air regulator open in the position shown in the Picture.
IMPORTANT:
• do not add further wood between one complete load and the next;
• do not suffocate the fire by closing the air intakes;
• regular cleaning by a chimney sweep reduces fine particle emissions.

NORMAL OPERATION

After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous
stresses and deformations.
You should always use the product with the door closed in order to avoid damages due to overheating (forge
effect). The inobservance of this rule makes the warranty expire.
IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the fuel. The hearth
door must always remain closed during operation or rest.
With the registers located on the front of the device, it is possible to adjust the heat emission of the same. They have to be opened
according to the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most part of
the air for combustion flows through the secondary air register.
Never overload the appliance. Too much fuel and too much air for the combustion may cause overheating and then damage
the product. You should always use the appliance with the door closed in order to avoid damages due to overheating (forge effect).
The adjustment of the registers necessary to reach the rated calorific yield is the following one: see chap. TECHNICAL DESCRIPTION.
The appliance works as an intermittent operating appliance.
In the event that the water temperature exceeds the tripping temperature of the safety devices, immediately
suspend the feeding of wood, and make sure that the water temperature and the flame decrease, eliminating the
causes of the overheating (if necessary by closing the air register). If the water system is connected in the thermo-
fireplace, the hot water tap can be opened to speed up the cooling of the appliance.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of
the device is influenced by the stack. A good draught of the stack requires a stricter adjustment of air for combustion, while a poor
draught requires a more precise adjustment of air for combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals
that the combustion is not complete (it is necessary a greater quantity of secondary air).
WARNING: When fuel is added onto the embers in the absence of a flame, a considerable amount of fumes may develop.
Should this happen, an explosive mixture of gas and air may form, and in extreme cases an explosion may occur. For safety
reasons it is advisable to perform a new lighting procedure with the use of small strips.

ELECTRICAL POWER SUPPLY FAILURE

In the event of an unexpected electrical power supply failure during normal system operation, it will be necessary to carry out these
simple manoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack of pump operation.
