7.2. PELLET

Pellets are realised by subjecting wood shavings i.e. the rejects of pure wood (without paint) sawmill, carpenter
products and products from other activities connected to working and transforming wood, to very high pressures.
This type of fuel is absolutely ecological as no glues are used to hold it together. In fact, the compactness of the
pellets is guaranteed through time by a natural substance that is found in wood: lignite
As well as being an ecological fuel, as wood residues are made the most of, the pellet also has technical advantages.
While wood has a calorific value of 4.4 kW/kg (with 15% humidity, therefore after about 18 months seasoning), that of
the pellet is 4.9 kW/kg.
Pellet density is about 650 kg/m
have to be seasoned in order to obtain a sufficiently adequate heat yield.
The pellet used must comply with the features described by the Standard:
La NORDICA recommends the use of pellets with a diameter of 6mm with its products.
The use of expired pellets or any other material, damages the functions of your stove and can determine the
invalidity of the warranty and the annexed responsibility of the manufacturer.
PELLET STORAGE
To guarantee combustion without problems, the pellets must be kept in a dry place.

FLOW OF AIR IN THE PLACE OF INSTALLATION DURING COMBUSTION

Because the wood burning stoves obtain their combustion air from the installation room, it is essential that the place
itself is supplied with a sufficient amount of air. If windows and doors are sealed, (e.g. houses built with the energy
saving criterion) it is possible that the entry of fresh air is no longer guaranteed and this could compromise the
draught of the appliance, your well-being and safety. Additional fresh air must therefore be guaranteed via external air
vents positioned in the vicinity of the appliance or by laying a pipe for the combustion air hat goes towards the outside
or a nearby aired room, with exception of the boiler room or garage (PROHIBITED).
This appliance has a connection fitting (D.150mm) to a flexible pipe for the external combustion air, which is placed at
the rear. The connection pipe must be smooth with a minimum diameter of 150 mm, must have a maximum length of
4 m and have no more than 3 bends. Whenever this is connected directly with the outside, it must be supplied with a
relevant wind protection.
The entry of air into the place of installation for combustion must not be closed during stove functioning. It is
absolutely necessary that as much air that is required for combustion is introduced, i.e. up to 20m³/hour, into the
environments where the stoves are made to function with natural draught
air must be guaranteed by some fixed apertures towards the outside, their size and stability by relative Standards on
the subject. Ask your local chimney sweep for information. The apertures must be protected by grills and must never
be blocked. An extraction hood (suction) installed in the same or adjoining room causes a depression in the
environment. This causes the burned gas to escape (thick smoke, odour) and therefore it is necessary to ensure a
greater flow of fresh air.
The depression of a suction hood can, in the worst case, transform the stove flue into an external air vent,
sucking the combustion gas back into the room with serious consequences for persons.

LIGHTING

IMPORTANT: on commissioning it is inevitable that an unpleasant odour is produced (due to the drying of glues in
the gasket seams or protective paints), which disappears after brief use. Good environment ventilation must be
assured. On commissioning, we recommend feeding a small amount of fuel and slowly increasing the calorific
yield of the appliance.
For correct commissioning of the products treated with high temperature paints, the following must be known:
• the construction materials of the products in question are not homogeneous. In fact, parts in cast iron, steel,
refractory material and majolica co-exist;
• the temperature to which the body of the product is subjected is not uniform: temperatures varying from 300° C to
500° C are recorded from area to area;
• during its life span, the product undergoes alternate switch-on and switch-off cycles during the same day and
intense cycles of use or rest on variation of the seasons;
• the new appliance, before being able to be described as seasoned, must be subjected to several start-up cycles in
order to allow all materials and paint to complete the various elastic stress;
