THE FUELTHE FUEL

THE FUELTHE FUEL

THE FUEL

Special attention must be given to the characteristics of the wood: like all biomass generators. The good
performance of the generator depends on the type of wood used and on its degree of seasoning.

The recommended fuel is normal wood having a moisture content of 10-20% and a thermal value of 2500-3500 Kcal/Kg. Using the right fuel, and
knowing which is in fact the most appropriate wood to use, is one of the most important aspects concerning the use of your central heating
cooker in order to prevent damaging it and the flue outlet.
All types of solid fuel are suitable but we recommend using only hard and well-seasoned wood.
We advise against using wet wood or wood that has been seasoned for less than 18/20 months, as it can cause malfunctions and the formation
of tarry deposits, as well as not giving the correct thermal performance. All woods have different heat outputs: for example, 1Kg of beech equals

1.15Kg of birch, 1.6 Kg of fir, 0.5 Kg of briquettes… The heat outputs can also vary considerably depending on the type of fuel used and on the
size of the piece of wood. Using pieces of wood that are too thick cannot guarantee the declared power yield. Do not burn generic waste or
plastic but above all never use petrol or other inflammable liquids. When using briquettes it is mandatory to halve the fuel consumption.

The use of fuel that does not conform to the specifications set out
above immediately invalidates the warranty on the central heating
cooker.

The central heating cookers series 25 - 30 - F25 - F30 - 60 - 65 - 90 - 95 can be supplied boiler body with vitrification
treatment. This treatment occurs at very high temperatures that permit the glass and steel to melt into an alloy
that is completely impervious to corrosion attack caused by acid combustion smoke. Vitrification protects the
boiler body from corrosion caused by acid smoke and condensation developed by the combustion of the wood
fuel. The presence of surface defects such as indents, scratches, etc..., do not affect the life or resistance of the
corrosion proofing treatment.

To install the safety heat exchanger remove the
vertical door, the left side together with its
insulation and the vertical upright that holds the
door together with its screws as indicated.
Slide in the heat exchanger (1) and secure it to
the boiler using the hardware (2) provided.
Close the hole with the plug (3). By installing a
thermal relief valve the excess heat is absorbed
as soon as the central heating cooker rises to
excessive temperature values due to external
causes. This function is called fast disconnection
phase.

A vital aspect to consider is that the flooring of the room in which the central
heating cooker is installed must be capable of bearing the weight of the
central heating cooker.
CAUTION: The room in which the central heating cooker is installed must be
adequately ventilated (1300 m3/h). Ensure that there is always a minimum

75mm safety gap between the central heating cooker and walls or
combustable materials. If inflammable items are positioned near the central

heating cooker (matchboarding, furniture, curtains, wall hangings, sofas,
etc...), this gap must be increased considerably. Adhere to the recommended
minimum distances illustrated in the drawing on the right. It is permissible to
install the heater near materials that are sensitive to heat as long as suitable
insulating protection is placed between the material and the heater (ref. UNI

10683).

For inset installations ensure that the top cast iron cornice is insulated from the surrounding
furnishings by means of lateral air spaces or compressed vermiculite insullation board

If you wish to integrate your central heating cooker with your kitchen furnishings or with a particular furnishing arrangement
remove the fold-away towel rack by undoing the 2 screws as illustrated in the figure below and then mount the enamelled
casing (only for models 25 - 30 - F25 - F30 ) . It is also advisable to apply 75mm spacers to the sides of the central heating
cooker to prevent the heat from the top cast iron cornice from damaging the adjacent furniture.
