9. PERMISSIBLE/NON-PERMISSIBLE FUEL
Monoblocco 400 Piano – 500 / 800 Angolo
Logs are the permitted fuel. You should only use dry logs (max water content 20%). Logs should be about 30 cm in
length and 30 cm in circumference.
Compressed non-resinated logs must be used with caution to avoid overheating that may damage the device,
as this type of wood features high heating value.
Wood used as fuel must features less than 20% humidity content and be stored in a dry place. Damp wood does not
burn well as a greater quantity of energy is required to make the water evaporate. Water content is also inconvenient
insofar that, when temperature lowers, water condensates initially in the hearth and then in the stack, causing a
considerable amount of soot to coat the stack and the potential risk of it catching fire.
Fresh wood contains about 60% of H2O and is therefore unsuitable for burning.
This wood should be kept in a dry ventilated place (e.g. under a shelter) for at least two years before use.
A non-exhaustive list of non-permissible fuel: coal, trimmings, waste bark and panels, wet wood or wood
treated with paints, plastics; use of this fuel will forfeit the device’s warranty.
Paper and cardboard should be used to light the fire only.
It is FORBIDDEN to burn waste as this can damage the device and flue, present a risk to health and, as it can
produce a foul smell, lead to complaints by neighbours.
Wood is not a long-lasting fuel so continuous heating throughout the night is not possible.
Continuous and protracted use of wood particularly rich in aromatic oils (e.g. eucalyptus, myrtle, etc.) causes
rapid wear (cleavage) of the cast iron components in the product.
10. LIGHTING
An unpleasant smell will invariably be produced when you light a fire in the hearth for the first time (due to drying of
the sealant glue or protective lacquering), but this will soon wear off. You should however make sure the room is well
ventilated.
To light the fire we recommend you use small pieces of wood and paper or similar material available in the shops.
It is FORBIDDEN to use any liquid agents such as alcohol, gasoline, oil and similar.
Put in a small amount of fuel and open the (primary and secondary) comburent air vents.
When the wood starts to burn, you can add more by opening the door slowly to prevent smoke from entering the
room, close the primary air vent and control secondary air for combustion, following the instructions in Chapter 0.
The hearth must be supervised during this entire phase.
Do not light a fire in the hearth if there are combustible gases in the room.
You should take the following notes into account when lighting a fire for the first time in a device treated with lacquers
for high temperatures:
• These products are built using non-homogenous materials such as cast iron, steel, refractory material and
majolica;
• The body of the product is subjected to non-homogenous temperature: temperatures can range from 300 to
500°C according to its various parts;
• There may be periods when fires are lit and extinguished on a regular basis, periods of intense use, or periods
when the hearth isn’t used at all due to the season;
• Several fires have to be lit in the hearth to allow all the device’s materials and lacquering to adjust to elastic
stress and allow the device to be properly seasoned;
• When you use the hearth for the first time, you will note the characteristic smell of the metal parts having to
withstand extreme thermal stress and fresh lacquer. Although this lacquer is baked at 250° for several hours
during the construction phase, it has to be brought up to 350° several times and for a good while for it to properly
adhere to the metal surfaces.
It is therefore important to take these small steps when lighting a fire:
1) Make sure there is good air exchange in the room where the device is installed.
2) At first, do not put too much fuel in the combustion chamber (about half the amount indicated in the instruction
manual) and keep the fire continuously alight for at least 6 to 10 hours, and with the air regulators less open than
indicated in the instruction manual.
3) Repeat this procedure 4-5 times, or more if possible.
4) Gradually use more wood at a time (still following the instructions on maximum capacity in the instruction
manual) and keep the fire burning for long periods of time. Avoid, if possible – at least during initial use – fires of
short duration.
5) Do not lean anything against the device and especially not against lacquered surfaces during initial use.
Do not touch the lacquered surfaces during the heating process.
6) Once the device’s “break-in” phase has ended, use it as you would a car’s engine, avoiding abrupt heating by
putting in too much fuel.
