1. PURPOSE
e stove is purposed to heat domestic and public premises by the means of pellets. e stove is
equipped with a steel water jacket designed for heating systems with water temperature up to 90º
C at a maximum super pressure up to 0,15 Mpa. Tests are run at pressure of 0,3 Mpa.
e stove is designed and manufactured to work with A-class pellets only
( DIN plus 51731 ) with the following characteristics:
• Material 100% pure conifer or broad-leaf wood;
• Diameter 6/8 mm;
• Length 20-30mm;
• Calorie capacity 5.2 kW/kg;
• Ash content < 8%;
e use of pellets with characteristics dierent from the recommended may result in power de-
crease, unstable and inconsistent work of the stove.
What are the pellets.
e pellets are produced by compressed wooden waste le from the production of various furni-
ture, sawmills and others. is type of fuel is environmentally friendly because in the production
process no agglutinate agents (glues, resins and others) are added. Actually, the integrity of the
pellets is guaranteed by the lignite – a natural ingredient contained in the wood itself. While the
wood has a calorie capacity of 4.4 kW/kg (15% humidity at 18 months drying), the pellets have
5.2 kW/kg.
Info: To ensure the proper work of the stove the pellets must be stored in a dry place!
Recharging of pellets can be done during work, with the following sequence:
1. Open the bunker (located at the top rear of the product);
2. Fill the hopper, using non-combustible container;
3. Close the lid of the bunker;
Attention!!! Use gloves! Beware of hot surfaces!

3. ASSEMBLY
3.1 General conditions.
For ensuring the proper and safe work of the stove the observation of the following prescriptions
is required:
e assembly of the stove and the related equipment must be performed by authorized personnel
only.
e foundation upon which the stove is going to be placed must be even and horizontal, made
out of non-ammable materials with a dimension of at least 40 cm. in front of the stove and not
less than 20 cm from both sides and the rear side.
If ammable materials or constructions are present, the distance between them and the stove
must be at least 80 cm.
When assembling the stove make sure that the joints between the separate pipes and the chimney
socket are well insulated.
A smell on rst start-up of the stove is due to the burning of the paint.
e stove is painted with thermal resistant paint which reaches its nal resistance aer a couple
start-ups and warm ups. THAT IS WHY THE OUTER SURFACES MUST NOT BE TOUCHED
in order to avoid damage to the casing.
e periodic cleaning of the ash tray must be done only when the stove is cold.

3.2 Basic rules and prescriptions.
e stove with water jacket operates on water heating stove principle.
e advantage of this type of heating system is the maximum utilization of the heat that is pro-
duced during the combustion process. With this method the heat from the combustion chamber
is taken to remote and hard to reach for a normal heat exchange premises in order to maintain an
even temperature and warmth comfort.
• Ensure that every branch and element of the installation is airtight at every single moment of its
exploitation.
• All elements of the installation must be protected from freezing, especially if the enlarging pot or
other parts are situated in non-heated premises.
• e circulation pump can be chosen by the capacity required by using the following formula:
G=0,043. P , (m³/h), in which:
P, kW is the heat output of the water jacket. e circulation pump can be turned on and o
by the means of a thermostat in combination with an electric switch
• e rst service cleaning of the pump’s lter must be done immediately aer testing the installation.
• If an old installation is going to be used it must be washed several times to ensure the removal of any
accumulated dirt on the surfaces of the water jacket.
• Do not drain the circulating water of the installation during the non-heated season.
• Chemical treatment of the circulating water is not recommended.
Chart 1 is a basic combined chart for heating with solid fuel stove, electrical stove equipped with water
serpentine and a solar panel. For economy and eciency of the system and a constant availability of
cheap hot water a qualied assembly of the automatic shier controlling the thermal ows to and out
of the solar panel and the stove is required.
Chart 2 shows a one storey heating with a compulsory circulation. e advantage of this chart is that
the water-conducting elements can be hidden.
e enlarging pot must have a direct atmosphere connection which means that it must be placed on the
highest spot in the system. Its capacity can be determined as 0,1 part of the total capacity of the system.
e lling or unloading of the system is done via a hose through a facet mounted in the lowest area.
Mounting a membrane enlarging pot is permitted when constructing a closed type system.
During the initial 3-4 start-ups a condensation on the surfaces of the water jacket may occur which de-
pending on the fuel’s humidity and the temperature of the incoming water may reach 0,3 litr on a single
start-up. e accumulating char reduces the temperature dierence and the condensation.
• “FERROLI” provides a warranty and out of warranty service and replacement of the water jackets.
• e warranty is not valid in case of a stove with a swollen water jacket which is a result of pressure
increase in the system and improper connecting.
• e water jackets are tested under pressure of 400 kPa (4 bar).
It is recommended that the assembly is performed by an authorized specialist.

3.3 Assembly of the duct components.
Duct components and pipes
For the assembly of the duct pipes the use of non-ammable materials, resistant to the ammable
products and condensation is obligatory. e assembly must be performed in such a manner so
it guarantees the airtight sealing and prevents condensation. If possible, avoid adding horizontal
sections. Direction shi is done by using knee joints with a max angle of 45˚.
For heating devices equipped with a smoke ventilator, i.e all of the “Ferroli” stoves, the following
instructions must be observed:
• Horizontal sections must have a minimum incline of 3° upwards;
• e length of the horizontal sections must be as short as possible, but without exceeding 3
m;
• More than four direction shis are forbidden, including the cases where a T-shaped element
is used;
• e duct components must be airtight and to be insulated if extending outside the premises
in which the replace is installed;
• e duct components must allow a soot cleaning;
• e duct components must have a constant section. A section change is allowed only in the
chimney joint;
Chimney
e chimney or the duct component must conform with the following requirements: to be air-
tight, waterproof and properly insulated, to be constructed with materials resistant to the normal
mechanical wear and to the heat coming from the combustion products and condensation.
• To be kept away from ammable materials.
e recommended chimney dra at work - from 12-20 Pa.
Attention!!! In case of a re hazard turn o the product from the display. is will stop the oxy-
gen ow to the product.
v
3.4 Air intake
Suction pipe or air intake is placed in the back
and has a circular section with a diameter of
48-60 mm.
e combustion air can be aspirated:
• From the camera, as long as it is near an
air intake communicating with the out-
side wall having a minimum area of 100
cm2, properly positioned and protected
by a grid.
• Or by connecting directly outside with a
suitable tubing having an inner diameter
of 48-60 mm and a maximum length of
1.5 M.2

4. Cleaning
Cleaning the replace should be done only when cold. e cleaning of the combustion chamber
must be carried out daily. For this purpose, make sure the replace has ceased operation and is
completely cold. Pull up the combustion pot and remove it from the stove and then clean it from
soot. When removed fuel pot at the bottom of the combustion chamber opens a hole designed for
the accumulated ash. Collect ashes in the ashtray and return fuel pot in place and then close the
door. e replace is ready for operation.
Cleaning of ues and chimneys are conducted once every 1.5 tons of fuel used
Once clean audits and close the cleaning lid. Check that the bolts are tightened well. Every time
you open check for violations of the isolation seal. If this happens do not use the product until the
isolation seal is repaired.

5 Safety and unexpected risks
Terms of danger may arise in the following cases:
• Automated pellet stove is used incorrectly;
• e unit is installed by unqualied personnel;
• e safety instructions described in this management are not met;
Unforeseen risks:
Pellet replace “FERROLI” has been designed and manufactured in accordance with the safety
requirements on the national, regional and European levels. Although considered possible risks
arising from improper use, you may experience the following risks:
• Risks of spreading combustion outside replace - opening the door of the chamber of the
replace may fall hot / burning particles (as hot ash and small particles burning coal), which
could lead to a re in the heated room. It is therefore necessary that the product always works
with a tightly closed door. It can only be opened when the product has completely cooled
down;
• Risks of burns caused by high temperatures as a result of the combustion process in the
combustion chamber and / or access to the door of this burn chamber when the product is
not completely cool;
In case of re hazard the product should be stopped by the controller and power supply until the
cause of the problem is determined.
