ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the
cast iron parts (cleavage) of the product.
The declared technical data have been achieved by burning beech wood class "A1" according to the requirement UNI EN ISO 17225-
5 and wood moisture content less than 20%. By burning a different kind of wood the efficiency of the product itself could change and
some specific adjustments on the appliance could be needed.

LIGHTING

ATTENTION: never light for any reason if the installation is not completely full of water in order to avoid a serious
damage of the whole structure. IABSOLUTELY DO NOT LIGHT THE FIRE IN THE THERMO-FIREPLACE IN THE
TOTAL OR PARTIAL ABSENCE OF WATER (NOT EVEN FOR CHECKING), AS IT COULD BE IRREMEDIABLY RUINED.
IN SUCH CASE THE WARRANTY ON THE APPLIANCE IS VOIDED.
Before installing the facing and lighting the thermo-fireplace, it must be loaded and the system filled from the open expansion tank by
means of the natural fall of the water (see chapter. SYSTEM CONNECTION AND FILLING).
After ensuring that at least one radiator is always open, open the door and load a small quantity of wood.
To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting means.
It is FORBIDDEN to use any liquid substance as for ex. alcohol, gasoline, oil and similar. Never switch on the
device when there are combustible gases in the room.
The openings for air (primary and secondary) must be opened together (you must open the eventual Ignition control, and butterfly
valve placed on the pipe of smokes exhaust). When the wood starts burning, you may load other fuels and adjust the air for combustion
according to the instructions on paragraph TECHNICAL DESCRIPTION.
Please always be present during this phase. Never overload the appliance (see the technical table - max. quantity of fuel that
can be loaded / hourly consumption). Too much fuel and too much air for combustion can cause overheating and therefore
damage the same.
After the first ignition you can smell bad odours (owing to the drying of the glue used in the garnitures or of the paint) which disappear
after a brief using of the appliance. A good ventilation of the room should always be guaranteed.
ATTENTION: during the first lightings there could be a solid smokes condensation with a small escape of water
from the thermo-fireplace: this event will expire in a very short time but if it persists it will be necessary to check
the chimney draught.
To perform a correct first lighting of the products treated with paints for high temperature, it is necessary to know the following
information:
• the construction materials of the involved products are not homogeneous, in fact there are simultaneously parts in cast iron, steel,
refractory material and majolica;
• the temperature to which the body of the product is subject is not homogeneous: from area to area, variable temperatures within
the range of 300°C - 500°C are detected;
• during its life, the product is subject to alternated lighting and extinguishing cycles in the same day, as well as to cycles of intense
use or of absolute standstill when season changes;
• the new appliance, before being considered seasoned has to be subject to many start cycles to allow all materials and paints to
complete the various elastic stresses;
• in detail, initially it is possible to remark the emission of smells typical of metals subject to great thermal stress, as well as of wet
paint. This paint, although during the manufacture it is backed at 250 °C for some hours, must exceed many times and for a given
period of time the temperature of 350 °C before becoming completely embedded in the metallic surfaces.
Therefore, it is extremely relevant to take these easy steps during the lighting:
1. Make sure that a strong air change is assured in the room where the appliance is installed.
2. During the first starts, do not load excessively the combustion chamber (about half the quantity indicated in the instructions
manual) and keep the product continuously ON for at least 6-10 hours with the registers less open than the value indicated in
the instructions manual.
3. Repeat this operation for at least 4-5 or more times, according to your possibilities.
4. Then load more and more fuel (following in any case the provisions contained in the installation booklet concerning maximum
load) and, if possible, keep the lighting periods long avoiding, at least in this initial phase, short ON/OFF cycles.
