THE AUTHORISED DEALER
•Installation and connection must be carried out by qualified staff in compliance with local regulations, national and European standards (UNI 10683 in
Italy) and with the annexed installation instructions. Furthermore, these operations must be performed by personnel who are authorised and professionally
trained for the task in question.
•The combustion of waste, especially of plastic materials, damages the stove and the flue pipe. Moreover, it is forbidden by the law against the emission
of harmful substances.
•Do not use alcohol, petrol or other highly inflammable liquids to light the fire or poke it during operation.
•Do not introduce into the stove an amount of fuel greater than that recommended in this booklet.
•Do not modify the product.
•It is forbidden to use the appliance with the door open or the glass broken.
•Do not use the appliance as, for example, a clothes drying rack, a bearing surface or step etc.
•Do not install the stove in bedrooms or bathrooms if not certified as watertight.
The wood to be used is as follows:
The wood log should have maximum 330mm in length and a maximum moisture content of 8%;
Dry wood produces more usable heat than wet wood as it produces less smoke, less soot and less carbon dioxide. Dry wood is the correct choice that allows you
to get the most out of your stove. Always remember to split the firewood to make it dry quicker: the higher its moisture content, the greater the amount of heat
necessary for it to ignite - heat subtracted from your well-being.
Based on the weight in kg of a cubic metre of material, the wood can be classified into “softwood” and “hardwood”.
"Softwood" (300-350 kg/m3 such as spruce, pine, poplar, alder, chestnut, willow) burns rapidly, producing a stronger heat; therefore, it is great for starting a fire but
to use it as fuel would require frequent refilling of the stove. “Softwood” can also produce more creosote, meaning that the chimney will require more frequent
cleaning.
“Hardwood” instead (350- 400 kg/m3 such as elm, oak, beech, ash) burns at a slower rate, resulting in sustained heat output and making this type of wood ideal
for domestic heating.
In terms of heating output, firewood can be divided into:
• Excellent quality: oak, ash, beech, maple.
• Fair quality: chestnut, birch and alder
• Acceptable quantity: lime, poplar and willow
THE CALORIFIC VALUE:
The calorific value depends therefore, on the density of the wood (that varies based on its type) and on its moisture content. The heat output of the stoves is directly
affected by this factors. Depending on its moisture content, it can be indicated in:
% of humidity
Calorific heat output kcal/kg
15%
3490
20%
3250
25%
3010
30%
2780
35%
2450
40%
2300
On average, a well seasoned wood has a calorific value of 3200 kcal/kg.
Eva Stampaggi S.r.l. declines any criminal and/or third party liability for any damage to persons or property arising from the failure to comply with the points
mentioned in this manual and from non-compliant product installation.

03.2 FLUE PIPE
STOVE CHARACTERISTICS FOR SIZING OF THE FLUE PIPE
The stoves have the following characteristics:
Chimney flue draught: 12 Pa
Fume temperature: 190 °C
Flue gas mass flow: 15.3 g/s
The flue pipe is one of the key features for guaranteeing the proper functioning of the stove. Thanks to the quality of the materials, the strength, the durability, the
easy cleaning and maintenance, the best flue pipes are made of steel, either stainless steel or aluminised.
•Use telescopic joint connections to facilitate connection to the steel rigid flue pipe and counterbalance the thermal expansion of both the firebox and the
flue pipe.
•Seal the flue pipe joint connection with high temperature silicone sealant (1,000°C). Should the existing flue opening not be perfectly perpendicular to
the firebox fume outlet, use an elbow to connect them. Inclination must never exceed 45°, with respect to the vertical axis.
•No constrictions. Use 10cm-thick insulating thimbles if pipe vent passes through floors.
•The flue pipe must be insulated along its entire length. Thanks to the flue pipe insulation fume temperature will remain high optimising draught, preventing
condensation and reducing build-up of barely ignited particles along the flue pipe walls. Use proper insulating materials (glass wool, ceramic fibre, Class
A1 non-combustible materials).
•The flue pipe must be weather-proof and as linear as possible.
•Flexible and length-adjustable metal pipes may not be used.
EXISTING FLUE PIPE (TRADITIONAL)

Types of flue pipe
Examples of flue pipe:
INCORRECT INSTALLATION
Exhaust pipes must never be fitted pointing downwards or horizontally so that fumes are discharged directly through the external wall.
03.3 CHIMNEY
A properly installed chimney cowl ensures optimum stove functioning. The anti-downdraught chimney cowl consists of a number of components whose outlet
section sum always doubles the flue pipe section. Make sure the chimney cowl is at least 150cm above the roof rise so that it is fully exposed to the wind.
The chimney cowls must:
•have useful outlet section that is at least twice that of the flue pipe.
•be made in such a way as to prevent the penetration of rain or snow.
•be constructed in such a way as to ensure, in the event of winds coming from any direction, the evacuation of combustion products.
•be free of mechanical intake auxiliaries.

03.4 DRAUGHT
Fumes heat up during combustion, increasing their volume. Their density is therefore lower than the one of the surrounding colder air.
This difference between the inside and outside temperatures of the chimney results in a negative pressure which increases proportionally to the flue pipe length
and the temperature.
The draught must be stronger than the fume circulation resistance so that all exhaust fumes generated during combustion inside the stove are drawn upwards
through the outlet and the flue pipe. Many weather conditions affect the flue pipe functioning, such as rain, fog, snow, altitude, and wind being the most important
as it can create both negative pressure and dynamic loading.
The wind action varies depending on whether it is ascending, descending or horizontal.
•Ascending wind always results in an increased negative pressure and draught.
•Horizontal wind results in an increased negative pressure as long as the chimney cowl was properly installed.
•Descending wind always diminishes the negative pressure, sometimes inverting it.
Excess draught causes an increase in the combustion temperature and consequently a loss in stove efficiency.
A part of the combustion fumes is drawn up through the flue pipe together with small wood particles before combustion reducing stove efficiency, increasing fuel
consumption and resulting in the emission of polluting fumes.
At the same time the high fuel temperature, due to an excess amount of oxygen, wears down the combustion chamber sooner than expected.
On the other hand, poor draught slows down combustion resulting in a decrease in the stove temperature, fume spillage inside the room, a loss of stove efficiency
and dangerous build-up in the flue pipe.
In order to avoid excessive draught it is appropriate to use:
-damper -draught regulator
12

03.5 STOVE EFFICIENCY
Highly efficient stoves may pose difficulties for fume extraction.
In order for a flue pipe to work properly its internal temperature must increase as a consequence of the fumes generated during combustion.
Importantly, the efficiency of a heater is determined by its ability to transfer most of the heat produced to the environment to be heated: consequently, the greater
the efficiency of the stove, the "colder" the residual fumes of combustion, and consequently, the lower the "draft".
A traditional chimney flue, with a rough design and insulation, is more efficient if used with a traditional open fireplace or a poor-quality stove where most of the
heat is lost with the fumes.
Therefore, purchasing a quality stove often entails modifying the existing chimney flue to obtain a better insulation, even when it already works properly with old
appliances. Poor draught results in the stove not operating when hot or in smoke spillage.
Connecting the stove pipe to an existing chimney flue that has already been used with an old appliance is a common mistake. In this way two solid-fuel appliances
share the same chimney flue, which is wrong and dangerous.
If the two appliances are used simultaneously, the fume load might exceed the existing chimney flue capacity resulting in downdraught. If only one appliance is
used, the fume heat will facilitate draught but the cold air coming from the other appliance not in use will cool down exhaust fume temperature again blocking the
draught.
Besides the problems described so far, if the two appliances are placed on different levels the communicating vessel principle might be interfered with, causing
combustion fumes to be drawn in an irregular and unforeseeable way.
03.6 INSTALLATION
Follow the instructions below before installing your stove.
Select the position where the stove is to be installed and:
•Arrange the connection to the flue pipe for fume extraction.
•Provide the external air intake (combustion air) and check for its presence: it must be drawn from a free space (not spaces where extractor fans exist or
without ventilation) or from outside.
•Arrange a discharge pipe for the condensate resulting from boiling.
•If possible, install it near the hydraulic manifold or however, in a suitable position so that you can easily connect it to the hydraulic system.
•Place the stove on the floor in a convenient position for the connection to the flue pipe and close to the combustion air intake.
•The appliance must be installed on a floor with an adequate loading-bearing capacity. Should the existing floor not comply with the requirement above, proper
measurements must be taken (for instance, the installation of a load distribution plate).
•All the structures which could catch fire if exposed to excessive heat must be protected. Floors made from wood or inflammable materials must be protected
using non-combustible materials (e.g. 4mm-thick sheet metal or ceramic glass).
•The appliance installation must ensure easy access for cleaning the stove, exhaust pipes and flue pipe.
•This appliance is not suitable to be installed on a shared flue pipe.
•During normal operation, the stove draws air from the room where it is installed. Therefore, an external air intake must be positioned at the same height of
the pipe located on the stove back. When it is operational, the stove can cause a negative pressure in the room where it is installed. Therefore there should
not be other naked flame devices in the same room.
•If the stove is to be installed in rooms where it is surrounded by combustible materials (e.g. furniture, wood cladding, etc.), the following minimum clearances
must be complied with:
SAFETY DISTANCE FROM COMBUSTIBLE
MATERIALS:
REAR WALL C = 0 mm
INSULATION THICKNESS C = 80 mm
SIDE WALL = 600 mm
RECESS B= 5 mm
FRONT R = 1000 mm
13

•Besides complying with the minimum clearances set above, we also recommend installing heat-resistant fireproof insulating panels (rock wool, cellular
concrete, etc.)
The following is recommended
Promasil 1000
Classification temperature: 1000 °C
Density: 245 kg/m3
Shrinkage at reference temperature, 12 h: 1.3/1000°C %
Cold crushing strength: 1.4 MPa
Bending strength: 0.5 MPa
Reversible thermal expansion: 5.4x10-6 m/mK
Specific heat capacity: 1.03 kJ/kg K
Thermal conductivity λ:
200 °C 0.07 W/mK
400 °C 0.10 W/mK
600 °C 0.14 W/mK
800 °C 0.17 W/mK
Thickness: 40 mm
•When it is operational, the stove can cause a negative pressure in the room where it is installed. Therefore there should not be in the same room other
naked flame devices, with the exception only of type c stoves (airtight).
•Make sure that the stove can draw the necessary quantity of combustion air: this must be from an open space (i.e. a space without exhaust blowers or
providing adequate ventilation) or directly from outside.
•Do not install the stove in bedrooms or bathrooms.
•Unpack the stove: be careful not to damage the product at the time of unpacking.
•Check the stove's legs and adjust them so that the stove is stable.
•Place the stove so that the door and any window openings are not against the walls.
•Join the coupling device to the flue pipe.
•The exhaust fume pipes must be suitable for wood-burning stoves and must therefore be made from coated steel or stainless steel, with a diameter of
150 mm and fitted with adequate seals.

Diagram 4 - Wood-burning stove with puffer and various heating sources.
In this case the stove will be connected to various sources of heat. You must install a contact or a sensor to control the various heating appliances or any valves
or pumps.
HYDRAULIC CONNECTION
The hydraulic connection of the stove must be carried out by qualified staff, who must ensure the conformity of the entire system.
Particular attention should be paid when installing the stove in an existing system (see hydraulic diagram) to make sure that it will operate in perfect safety, in
compliance with the regulation in force.
The interior of the hydraulic system must be washed before connecting the stove. You need to install a expansion tank suitable for the system and adequate safety
valves.
ATTENTION: the average flow temperature is 55°C: take this value into consideration when choosing the heating system. The maximum operating pressure is 1.5
bar.
Upstream of the hydraulic connections of the stove you should provide some gate valves so that you can disconnect it from the system if necessary.
The condensate resulting from boiling must be suitably conveyed and collected to protect the floor.
If the KIT for the production of Domestic Hot Water is installed, the water used should have suitable characteristics so as to prevent the formation of limestone
inside the exchanger; water hardness > 25° French degrees, appropriate water softener.
The manufacturer declines any liability for any damage to persons or property arising from non-compliant product installation.
ELECTRICAL CONNECTION
The electrical connection must be performed by qualified personnel who install circuit breakers upstream of the appliance.
Special attention should be paid when the stove is parts of the system and all equipment must operate as planned.
Avoid installations with electric cables that run close to fume pipes or hot components that are suitably insulated.
The voltage is 230 V while the frequency is 50 Hz.
The electrical system where it is connected must be fitted with a conductor as required by the Regulations 73/23 EEC and 93/98 EEC.

-Technical menu: the technical menu is reserved for the cooker stove installer.
-Alarms: in this section of the menus is displayed any ongoing alarm. The alarm can be disabled by pressing the buttons P1 and P4. Alarm deletion is confirmed
by a long beep. The alarms are:
•Sensor 1 open: the sensor is not connected.
•Sensor 1 short-circuit: the sensor is damaged.
•Sensor 2 open: the sensor is not connected.
•Sensor 2 short-circuit: the sensor is damaged.
•H2O level sensor failure: if the sensor does not switch off within a given period of time T after the tank is fed with water, due to boiling or any other reason,
the stove enters the H2O level sensor failure alarm condition.
•Hot water: the temperature of the water inside the boiler exceeded the maximum threshold.
Installation with Contact (external thermostat):
For the version with contact (valid for diagram 2,3,4): the display shows the temperature of the boiler. When the contact opens, the display shows T OFF and output
V2 is powered. When the contact closes, the display shows T ON.
EXAMPLE:
When the contact opens because the boiler requires hot water, the three-way valve switches towards the boiler and the display shows T OFF. Once the stove
meets the water requirement, the contact closes and the display shows T ON.
Installation with Probe:
For the version with sensor (valid for diagram 2,3,4): the display shows the boiler temperature and the measured temperature alternately. The sensor is adjusted
by T3. Therefore, if the temperature measured by the sensor is below T3, output V2 is enabled. If the temperature measured by the sensor is above T3, the 3-way
valve returns to its stand-by position.
EXAMPLE:
If the temperature measured by the sensor is lower than T3, a 3-way valve is enabled and it switches towards the boiler. If the temperature measured by the sensor
is above T3, the 3-way valve returns to its stand-by position.
04.2 IGNITION
CHECKS BEFORE START-UP
After connecting the stove to the hydraulic system and the electrical system you need to:
•Fill the system slowly, with the cap of the automatic release valve open. The system must be filled slowly so as to allow any air bubbles to come out of
the stove exchangers.
•If necessary, bleed the radiators.
•Fill the boiler tank: you can use a container or wait for it to be filled by means of the automatic fill valve (after 5 minutes of operation of the automatic
valve, the display might show the H2O LEVEL SENSOR FAULT alarm. Reset the alarm by pressing buttons P1 and P4 at the same time).
•The water should cover the exchangers but it should not exceed the limit of the discharge pipe.
•Do not start the stove if the tank is empty: you will not be able to heat your home and you also might damage the stove.
To light the cooking stove, small (dry) logs and possibly ecological fire-lighters are required. Open the primary air register located on the front of the ash drawer
and place the wood logs. After positioning the logs, place the fire starters below the wood and light them up. Close the door and wait for the flame to reach all the
wood logs. Good ignition depends very much on the draught of your flue pipe: if the ignition is difficult, the flue pipe will not have the recommended draught due to
the fact that it is cold and the stove will require more time to reach the intended operating conditions. In this case, we recommend that you open the ash drawer or
keep the fire door slightly open. Make sure the internal fume diverter/register (if provided) is open (turn counter-clockwise).
CAUTION:
Never use flammable liquids to ignite the wood logs. Also, after turning the stove on, keep in mind to close the primary air register. If you fail to close it, the stove
might overheat and might get damaged. Also, the paint might still be fresh and it might release intense odours. Therefore, you should make sure that the room is
properly ventilated before igniting the stove for the first time. Open the doors and windows to remove any odours from the room. The product might also suffer
slight deformations as its structure is made of steel; therefore you might hear slight noises or crunches. This is absolutely normal and should not be considered a
defect.
The display is off during the ignition phase. It will turn on once the temperature of the water inside the boiler exceeds 30°C.

Do not introduce into the stove an amount of fuel greater than that recommended in this manual.
When reloading the wood it would be advisable to open the primary air adjustment device or even the ash drawer, slightly open the door so that the stove takes
in oxygen, load the wood and close the firebox door
CAUTION:
•Do not introduce into the stove an amount of fuel greater than that recommended in this manual.
•Don't smother the fire by closing the air vents.
•Do not leave the primary air register open during normal operation to prevent the device and the water inside the boiler from overheating, subsequently
deforming the stove.
•Do not leave the firebox door open.
•Use proper protective equipment during refuelling: the firebox door handle and the registers might be very hot when the stove is running.
•If the coals are extinguished, light them up with new wood shims to start the fire.
•It’s your job to find the perfect combination between ignition and amount of air (by adjusting the register) so that your stove functions properly, according
to the characteristics of the chimney flue and of the wood.
•The top plate has been treated with food grade Vaseline. It’s role is to protect the material against oxidation. This product is non-toxic and it will evaporate
on his own at the first ignition.
The pump starts once the water inside the boiler reaches 55 °C and makes the water circulate inside the hydraulic system through the immersed coils. We
recommend that you never set T1 at a value below 55°C to prevent the formation of condensate inside the boiler. The oven is heated by the fumes surrounding it.
After the fire is properly started, if you want to increase the temperature inside the oven you have to rotate the lever installed above the plate clockwise and close
the internal fumes diverter so that they can circulate around the oven, increasing the temperature inside it.
04.4 PRODUCTION OF DHW PLUS
The models with built-in water heating system can produce domestic hot water instantaneously. Press the P3 button if you want to use all the power of the stove
to heat water. This way, the pump will be locked for 15 minutes to prevent it from changing the heating circuit. That period may be interrupted by pressing the same
button for 5 seconds. The pump restarts automatically when the water inside the boiler exceeds 85°C.

04.5 ICE ANTI-BLOCK FUNCTION
The pump cycles start automatically to ensure the perfect efficiency of the stove at any time, preventing its deterioration and any possible malfunction. When the
temperature inside the boiler drops below 6°C, the system starts the pump to prevent the formation of ice.
04.6 AUTOMATIC FILLING VALVE
Inside the stove is installed an automatic fill valve. It is enabled in the following cases:
•Low water level: the level sensor detects when there is very little water inside the boiler due to evaporation. The sensor sends a signal to the control unit
which controls the solenoid valve.
•Thermal safety: it keeps the temperature inside the boiler under control in case of overheating.
05 CLEANING AND MAINTENANCE
05.1 INTRODUCTION
The stove requires a simple yet constant cleaning to guarantee top efficiency and proper functioning.
Constant maintenance by a qualified technician is recommended.
The stove should be cleaned before the cold season because it can sometimes get clogged during the summer (by nests for example) preventing exhaust fumes
to flow regularly.
At the beginning of the season and in case of wind, a build-up of residue in the pipe may lead to fires. Should this happen, find below a few pieces of advice to
follow:
•Block air supply to the pipe immediately;
•Throw sand or kitchen salt, and not water, to extinguish fire and coals;
•Keep objects and furniture away from the burning pipe.
ALSO TO PREVENT THIS TYPE OF FAULT YEARLY CLEANING OF THE FLUE PIPE IS ESSENTIAL, REMOVING DEPOSITS OR ANY POCKETS OR
OBSTRUCTIONS.
05.2 DAILY CLEANING
Any cleaning operation must be performed when the stove is completely cold:
•Empty the ash drawer: vacuum it out or dispose of the ashes in a waste bin.
•Vacuum the combustion chamber: check that there are no embers that may still be lit. In this case your dust vacuum cleaner will catch fire.
•Remove the ash inside firebox and on door.
•Clean the glass with a damp cloth or with a ball of damp newspaper dipped in ash. If the operation is performed with the stove hot there is a risk of the
glass exploding.
CAUTION: USE A DRY CLOTH TO CLEAN THE STOVE EXTERNALLY. DO NOT USE ABRASIVE MATERIALS OR PRODUCTS THAT COULD CORRODE
OR WHITEN THE SURFACES.
05.3 MANUFACTURER’S RESPONSIBILIES
The manufacturer shall not be held liable against any direct and/or indirect, criminal and/or third party liability arising from:
•failure to abide by the instructions contained herein.
•non authorised repair operations or changes.
•use not compliant with safety rules.
•installation not compliant with national current regulations and safety rules.
•insufficient maintenance.
•the use of spare parts that are not original or which are not specific to the stove model.
06 TROUBLE-SHOOTING
•The stove does not heat: the wood is too wet or of poor quality; insufficient chimney flue draught.
•The stove heats too: excessive chimney flue draught; door or drawer gaskets replacement.
•Bottom grate locked: check the grate and make sure there are no nails or wood pieces stuck in it.
•Blackened glass: wood too wet or of poor quality, poor draught, insufficient combustion air, register closed too quick.
