• Bring the flue gas register to the oven position.
When the wood starts to burn, it is possible to load other fuel, close the primary air register and check combustion using secondary air
following the instructions in paragraph 9.1. During this phase, never leave the cooker unsupervised.
CAUTION: when lighting for the first few times, it is possible to find consistent flue gas condensation with slight leakage of water
from the thermocooker; this is a phenomenon which should disappear in a very short time. If it results as persistent, it will be
necessary to have the flue draught checked.
Never overload the thermocooker. Too much fuel and too much air for combustion can cause overheating and therefore damage the
thermocooker. The damage caused by overheating is not covered by the warranty.

9.1. NORMAL OPERATION

WARNING: For no reason turn on the fire before the system has been completely filled with water; doing so could cause serious damage
to the entire structure.
The appliances with automatic door closing (type 1 - type A1), must operate, for safety reasons, with the furnace door closed (with the
exception of the fuel loading phase or any ash removal).
Appliances with non-automatic door closing (type 2), must be connected to their own flue. Operation with the door open is only allowed
under supervision.
IMPORTANT: For safety reasons, the furnace door must only be open during the ignition phase and for loading wood whilst
during operation and periods of non-use it must remain closed.
The nominal calorific power of the thermocooker is reached with a minimum draught (depression) of 17-20 Pa (=1.7-2 mm of water
column).
It is therefore necessary to always use the thermocooker with the door closed to prevent the "forge" effect. The thermocooker must never
be overloaded. Too much fuel and too much air for combustion can cause overheating and therefore damage the thermocooker. The
damage caused by overheating is not covered by the warranty.
The emission of heat from the furnace is adjusted with the registers placed on the front of the thermocooker. These must be open according
to calorific need. The best combustion (minimum emissions) is reached when, loading wood, most air for combustion passes through the
secondary air register.
IMPORTANT: during normal cooker operation, the register lever,
inwards on the cooker). In this way, excessive fuel consumption is avoided (register closed).
The register regulation necessary in order to obtain nominal calorific output is the following :
Fuel
Wood (length 30cm, circumference 30 cm's)
n 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.
The intensity of combustion and therefore the calorific output of your thermocooker are influenced by the chimney. Good chimney draught
requires less regulation of the quantity of combustion air, while insufficient draught requires a larger quantity.
IMPORTANT: to check that combustion is taking place correctly, verify that the smoke which comes out of the chimney is transparent. If
it is white, it means that the thermocooker is not regulated correctly or the wood is too wet; if, on the other hand, the smoke is grey or
black, this means that combustion is not complete (a greater quantity of secondary air is necessary).
REFUELLING : If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke emission can occur.
Refuelling must be carried out onto a sufficient quantity of glowing embers and ash that the new fuel charge will ignite. If the fire bed is
too low or cool, suitable kindling must be use to re-light fires.

9.2. OVEN USE (if present)

After having cleaned the furnace grill, load the fuel. Thanks to the supply of air for combustion, the oven temperature can be influenced
slightly. Sufficient chimney draught and very clean channels for the flow of scorching flue gas around the oven are essential for a good
cooking result. (Chapter 5 - Flue register).
The oven pan can be placed on various levels. Thick cakes and large roasts should be inserted at the lowest level. Thin cakes and biscuits
go on a medium level. The highest level can be used for heating or browning.
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.

9.3. 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.
