Dear Customer,
We wish to thank you for choosing a CSTHERMOS stove and welcome you into our pellet/biomass/sized chip
heating world.
We remind you that our products are manufactured wholly in Italy with superb quality materials and are accurately
tested in compliance with the provisions of the safety regulations in force.
Great innovation and sophisticated design are added to this guarantee of quality and comfort.
These stove models can be tted with a traditional type pellet boiler that would use only best quality wood pellets
complying with the ISO EN 17225-2 reference standards and their updates, or with an innovative and patented
biomass boiler capable of burning not only any kind of wood pellets (for instance consisting of bark and branches)
but also biomass from agricultural waste such as maize, grapeseed, almond-walnut-hazelnut-pine nut shells, olive
stones, vine runners, etc.
An automatic cleaning system is managed by an electronic board that keeps the burner always clean, obtaining
great eciency and reliability of use.The modulating operation varies according to the set ambient temperature and
therefore allows optimal room heating. During the initial ignition phase (about 10 minutes), the burner automatically
lls with fuel, while resistors, heating up, trigger the ame. Once the ame has been detected by the combustion
fume detector, normal operation begins that, thanks to the microprocessor, allows changing the supply of fuel,
obtaining therefore ame modulation.
The electronic board checks the temperature sensors, electrical motors and safety devices continuously and, in
case of an anomaly, stops their operation and shows this on the display (see alarm code paragraph). The heating
of the environment is guaranteed by an air ow that varies according to the operating power going through the
combustion smoke pipes.
Models with biomass burner: do not exceed 60% corn in the mixture with the wooden pellets. Other chopped
fuels (i.e.: olive stones, shells, etc.) can be used "unmixed" with the wooden pellets, but they must have a minimum
diameter of 4mm.

4 - TRANSPORT AND HANDLING
The apparatus must be lifted with a winch tted with a hook (A) and handled with a transpallet or forklift
truck of suitable capacity.
The area of movement must be free from objects or people not involved in the transport operation.
If the equipment is handled using a winch, it is necessary to use some spreader bars (C) between the
lifting ropes, to prevent the unit from being damaged and ensure no excessive pressure is applied to the
packaging or machine itself.
Lifting with a winch tted with a hook
Use hooks of capacity and material suitable to the weight to be lifted. Ensure the safety lock (D) is in the
correct position while lifting.
Do NOT move the equipment if the eld of vision is
poor or if there other other obstacles along the way (i.e.
electrical cables, lintels, etc.). The range of action of the
lifting equipment must be kept free from people when
the loads are lifted.
Shifting must always be vertical. Use steel hooks, chains
or cables in perfect condition, of a suitable material and
capacity and without any joints or extensions (E). Carry
out periodic checks to guarantee eciency.
To anchor the unit, pass the ropes or chains through
the pallet holes (B), paying attention it is kept perfectly
level.
Check the atness of the ground where the lifting
equipment is standing, making sure it is stable and not
prone to subsidence.
Do not move the lifting equipment during the
operation.
Before starting lifting, check correct anchoring to the
mentioned points and the centre of gravity, then slowly
lift the packaged equipment to the minimum height
required and move it carefully to avoid dangerous vibrations.
Take care of the control panel that must undergo no impacts or be exposed to the weather (rain,
humidity): any damage may aect its operation.
Avoid sudden stops of the lifting or descending movement, in order to avoid dangerous oscillations.

There are numerous types and qualities of wooden pellets on the market, so it is important to choose one that con-
tains no glue, resins or chemicals and may cause early clogging of the smoke discharge, the formation of corrosive
gases, loss of eciency and the emission of polluting substances into the atmosphere. The pertinent regulations
state that the products working with this fuel must use good quality, compact and not very oury pellets. Please ask
your retailer for a suitable type of pellets, complying with ISO 17225-2 standard.
The characteristics of the wooden pellets to use are as follows: 6÷8 mm in diameter, about 5÷20 mm in length, 8%
humidity and 18200 kJ/kg caloric value.
The Manufacturer accepts no responsibility for the use of FUELS OTHER THAN AS STATED or the
possible malfunction of the unit.
Stack the fuel bags at at least 1 metre from the equipment.
Using biomass (corn, grapeseed, other) as fuel, it is important to ensure that the mixture is correct
for the stove to operate correctly. Do not exceed 60% corn in the mixture with the wooden pellets.
Other chopped fuels (i.e.: olive stones, shells, etc.) can be used "unmixed" with the wooden pellets,
but they must have a minimum diameter of 4mm. To get a correct mixture, weigh each fuel with a
set of scales having a 100g precision factor and mix them together in a container outside and not
inside the stove container, since it is not possible to obtain the necessary homogeneity inside.
7.1 Setting the fuel
Before switching the unit on, select the type of fuel to use from the display menu, following the procedure described
below:
- Select "Fuel 1" to use certied wooden pellets (ISO EN 17225-2) or good quality pellets with little humidity (<13%)
and low ash content.
- Select "Fuel 2" to use wooden pellets with a high degree of humidity (>13%) and high ash content.
- Select "Fuel 3" to use corn (max humidity 15%) mixed with wooden pellets
- Select "Fuel 4" to use biomass with humidity lower than 15%, such as chopped or whole olive stones (Ø 4mm
minimum), almond-hazelnut-pine nut shells (Ø 4mm minimum), pelletized vine shoots, cherry stones (Ø 4mm
minimum), miscanthus pellets, agripellets.
- "Fuel 5" is at the technician's/dealer's discretion for settings to be used with unsuitable fuels or fuels that have
not been mentioned previously.
For the stove to work correctly and performance to be high, it will therefore be necessary to change
the list of fuels, selecting the most suitable.
Do not exceed 60% corn in the mixture with the wooden pellets. Other chopped fuels (i.e.: olive
stones, shells, etc.) can be used "unmixed" with the wooden pellets, but they must have a minimum
diameter of 4mm.
