9. LIGHTING

WARNING: 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. It must be ensured, in any case, a good ventilation of the environment. Upon the
first ignition we suggest loading a reduced quantity of fuel and slightly increasing the calorific value of the equipment
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.
5. During the first starts, no object should be leaned on the appliance and in detail on enameled surfaces. Enameled 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.
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.
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 appliance. The warranty does not cover the damages
due to overheating of the equipment.
Never switch on the device when there are combustible gases in the room.

9.1. 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.
For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for removing
the ashes, while during the operation and the rest, the door of the hearth must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under supervision.
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 controls positioned on the front of the appliance it is possible to adjust the heat emission of the hearth. 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 (see the hourly wood load in the table here below). Too much fuel and too much air for the combustion may
cause overheating and then damage the stove. You should always use the appliance with the door closed in order to avoid damages due
to overheating (forge effect). The inobservance of this rule makes the warranty expire.
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 12 Pa 1,2mm of column of
water) is the following one: see chapter TECHNICAL DESCRIPTION.
The appliance works as an intermittent operating 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).
