•
the construction materials of the involved product are not homogenous, in fact cast iron parts do exist at the
same time, in steel, in refractory material and in 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 ar e 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 device, 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 paint that is still wet. 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 device 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 device 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.
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.
11. NORMAL OPERATION
After having positioned the registers correctly, insert the indicated hourly wood load (see CHAP. 18) avoiding
overloads that cause anomalous stresses and deformations. You should always use the FOCOLARE with the
door closed in order to avoid damages due to overheating (forge effect). The inobservance of this rule makes
the warranty expire.
With the registers located on the front of the device (Picture 1), 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 (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 stove 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 with a depression at the stack of 13 Pa
(1.3 mm of column of water) is the following one:
FUEL
Wood (length 30cm, circumference 30 cm )
Max quantity in ( kg/h )
3,8
Primary air
Closed
Secondary Air
Opened
This is an appliance with intermittent operation.
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).
To avoid damages to the monoblock due to an excessive overheating of the same (forging effect), remember
to use it always with closed (lowered) door.
