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 .
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.
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 .
10. 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 17-20 Pa 1,7-2 mm of column
of water) is the following one: see chapter 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).
10.1. USE OF THE OVEN (If present)
Thanks to the air flow for the combustion, the temperature of the oven may become remarkably affected. A sufficient flue of the chimney
and of the channels, well cleaned for the flow of burning smokes around the oven are fundamental for a good cooking result. The oven pan
may be located on different plans. Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and biscuits must reach
the medium level. The upper level may be used to heat or grill.
The thermocooker is equipped with a cast iron furnace grill which can be removed using a specific handle. The upper position optimises
the use of the hotplate while the lower one optimises water and oven heating Picture 9 at page 55 .
10.2. 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.
1. Raise the moveable furnace grill (if present ) to the highest level in order to reduce the exchange surface exposed to the heat of the
flame.
2. Close the primary and secondary air registers in addition to turning the thermostat to 0 ( if present).
3. Open the oven door (if present) in order to favour the elimination of the internal heat.
4. Open the flue gas register ; in this way, it will deviate the residual heat still produced towards the chimney.
10.3. OPERATION IN TRANSITION PERIODS
During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that the
combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the air
for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the flames) and the stabilization
of the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tigh.
In case of doubt, do not operate the product.
