Frequently Asked Questions - Ecofire Marianne 9 air Palazzetti

What type of pellets should I use?

Use exclusively wood pellets class A1 (ISO 17225-2, ENplus A1, DIN Plus or equivalent). Pellets must be between 3 and 40 mm in length. Avoid moist or low-quality pellets which reduce efficiency and foul the brazier.

How to clean the glass?

Wait until the appliance is cold. Use a damp cloth or dampened paper dipped in the ashes. Rub gently until the glass is clean. Never use abrasive products, solvents or harsh detergents.

What is the safety distance from walls?

Observe the following minimum distances: 800 mm in front (X1), 100 mm on the sides and rear (X2, Y1, Y2), and 600 mm above (Z). For flue pipes, follow the indications on the rating plate.

What to do in case of malfunction or alarm?

If the appliance displays an alarm or operates abnormally, turn it off and unplug it. Contact an authorized Palazzetti technician. Do not attempt to repair internal components yourself. Common alarms (e.g. lack of pellets, low pressure) are described in the manual.

Can I use an external room thermostat?

Yes, the stove can be set to Configuration 2 with a room thermostat (not supplied). Connect it to terminals 1 and 2 of the terminal board and remove the shunt. The thermostat turns the appliance on and off according to the programmed temperature.

How to perform the first ignition?

The first ignition must be carried out by the installer. Fill the hopper with pellets, plug in the appliance and set the switch to position 'I'. A series of beeps and the screen lighting up indicate the appliance is ready. Follow the instructions in the display manual.

How often should the brazier be cleaned?

The brazier must be cleaned before each ignition or at least daily. Remove the ashes and check that all holes are free to ensure good combustion air circulation. A dirty brazier can cause explosions or malfunctions.

Can the stove operate without electricity?

No, the stove requires an electrical supply for the fan, ignition and control system. In case of a power cut, the appliance turns off and restarts automatically when power is restored (depending on the configuration).

How to optimize combustion?

After the first installation, you can adjust the combustion value via the 'Combustion' menu (function 14). If excessive residues appear in the brazier, increase the value in steps until a stable flame and little ash is obtained. Consult the manual for more details.

How to store pellets?

Store the pellet bags in a dry place, away from humidity and at moderate temperature. Do not store them within one meter of a heat source. Avoid fragmenting pellets as sawdust can block the feeding system.

It is prohibited to use the appliance if the door glass or gaskets are damaged.

Any type of unauthorised handling or replacement with non-original spare parts shall place the safety of the operator at risk and relieve the manufacturer of any civil and criminal liability.

It is prohibited to manually load pellets into the burn pot; this type of incorrect behaviour may generate an abnormal amount of unburned gas, giving rise to the risk of explosion inside the chamber.

Unburned pellet deposits in the burn pot after a failed ignition must be removed before making a new ignition attempt.

If the burn pot is not cleaned and regularly serviced, malfunctions and explosions may occur inside the appliance. Be sure to remove all traces of material and deposits from the holes of the burn pot and to clean them each time the ash is emptied or after each failed ignition attempt. Make sure the burn pot holes don't decrease in size as this may have a negative effect on the safe operation of the appliance.

Do not wash the product with water. Water may infiltrate the unit and damage the electrical insulation, causing electric shocks.

Do not sit/stand in front of the product in operation for long periods.

Incorrect use of the product or incorrect maintenance works may create a serious risk of explosion in the combustion chamber.

Only use the fuel recommended by the manufacturer. The product must never be used as an incinerator.

It is prohibited to use benzene, lamp fuel, kerosene, liquid firelighter for wood, ethyl alcohol or similar liquids to light or rekindle a flame in this appliance. Keep these liquids at a due distance from the appliance during operation.

It is prohibited to insert other types of fuels in the tank other than wood pellets.

Some tips to avoid corrosion phenomena:

• carry out routine cleaning operations to avoid the build-up of ash deposits;
• feed the appliance only with fuel having the characteristics described in the section "Fuel characteristics";
• Do not use solvents, acids, aggressive detergents or products to directly clean the glass or other components of the product;
• avoid leaving the product in unfavourable ambient conditions (humidity, airborne salinity, storms, etc.);
• if the appliance is not used for long periods (e.g. during the summer), disconnect the combustion air inlet pipe and place dessicant bags in the combustion chamber to absorb the humidity in the air, making sure to remove them when the product is re-ignited.

3 FUEL CHARACTERISTICS

3.1 Fuel characteristics

The pellet (Fig. 2) is a compound made from various types of wood pressed together with mechanical procedures in compliance with environment protection regulations, and it is the only fuel required for this type of appliance.

Pile of cylindrical wooden sticks, likely wood or rubber, with no visible text or symbols.

The efficiency and thermal potential of the appliance may vary according to the type and quality of the pellets used.

We recommend the use of class A1 pellets (ISO 17225-2 standard, ENplus A1, DIN Plus or NC 444 category "High Performance NF Pellets Biofuel Quality").

Use pellets with standard length between 3 and 40 mm.

Using poor quality pellets or pellets that do not comply with the manufacturer's indications may compromise the normal operation of the appliance, cause damage (including aesthetic damage) to the product and result in the warranty being voided.

It is prohibited to use the appliance as an incinerator to burn rubbish.

The appliance is equipped with a pellet storage tank having the capacity indicated in table "4.3 Technical features" on page 51.

The loading compartment is positioned at the top, it must always be open for loading of the pellets and must remain closed while the appliance is operating.

3.2 Pellet storage

Pellets must be kept in a dry place, not too cold and the bags must be kept sealed.

It is advisable to keep a number of bags of pellets in the room where the appliance is being used or in an adjacent room provided it is at the correct temperature and humidity and at a safe distance (at least one meter) away from heat sources.

Wet and/or cold pellets (5 °C) reduce the thermal potential of the fuel resulting in the need for more cleaning maintenance of the burn pot (unburned material) and of the fire box.

Pay particular attention to the storage and handling of pellet bags. Their crushing and the formation of sawdust must be avoided.

If sawdust is placed in the appliance tank it could cause the pellet loading system to block.

5 HANDLING AND TRANSPORTATION

The appliance is delivered complete with all the parts required.

Pay attention to the tendency for the appliance to become unbalanced.

The centre of gravity of the appliance is carried towards the front.

Bear in mind the above also when moving the appliance on the transport stand. It is advisable to unpack the appliance only when it has arrived at the installation site.

The product must be handled and unpacked using suitable means.

Make sure that children do not play with the packaging components (e.g. films and polystyrene):

Danger of suffocation!

During moving, lifting, and unpacking of the appliance the following is absolutely necessary:

• always keep it upright;
- never tip it over into a horizontal position;
- never tilt it on the front to avoid breaking the glass of the fire box door.

- Removal of the transport pallet

Disposal can be entrusted to a third party, provided only companies authorised for the recovery and elimination of the materials in question are used.

Always follow the regulations in force in the country in which the appliance is being used for disposal of materials and possibly for the disposal report.

To remove the appliance from the transport pallet:

• Unscrew the side fixing screws
• Remove the fixing brackets
• Lift the appliance
• Remove the transport pallet

5.1 Transportation

Make sure that the lifting carriage has a payload higher than the weight of the appliance to be lifted. The full responsibility of the lifting of loads lies with the person handling the lifting equipment.

Ensure wood or timber floors are properly protected in order to prevent the weight of the appliance from damaging them during movement.

During lifting, avoid jerking or abrupt movements.

Pay attention to overbalancing.

5.2 Checking the floor where the appliance will be placed

Check the load capacity of the floor slab.

If a floor is not suitable for supporting the weight of the appliance, install appropriate steel plates (A - Fig. 10) or concrete base (A - Fig. 11) equipped with 10x10x6 electro-welded mesh (B - Fig. 11) to distribute the weight.

For the dimensions of the plates and the concrete base, use a qualified technician.

6 PREPARING THE PLACE OF INSTALLATION

6.1 General considerations

The following sections contain some guidelines to be followed to obtain the maximum efficiency of the product purchased and to ensure safe operation. The following indications are however subject to compliance with any possible national, regional and municipal laws and regulations in force in the country where the appliance is installed.

For Italy, installation must be carried out by qualified personnel in compliance with the EN 10683 standard.

6.2 Safety Precautions

The operations for assembly and disassembly of the appliance are reserved for specialist technicians only.

It is recommended to be sure of their qualifications and their actual capacity.

For Italy, these technicians must be in possession of the letter "C" qualification issued by the chamber of commerce based on the Ministerial Decree. 37/08.

6.3 Place of installation

For the minimum distances that must be respected when positioning the appliance with respect to flammable materials and objects, refer to the instructions in Fig. 12.

Z Y2 X2 X1 Y1 Fig. 12

Model X1 X2 Y1 Y2 Z
MARIANNE	800	100	100	100	600	mm

Floors made of flammable material such as wood, parquet, linoleum, laminate or floors covered with carpets must be protected by a fireproof base under the appliance that also protects the front during cleaning from any falling burning residues.

The manufacturer declines all responsibility for any variations in the characteristics of the material constituting the floor under the protection.

Set up an accessible technical space for any maintenance work.

Remember to respect the minimum distance from flammable materials (X), shown on the identification plate of the pipes used to make the chimney (Fig. 13).

Pi = Flammable wall

Pp = Floor protection

Pi X Pi X1 Pp Fig. 13

Set up the electricity supply line to arrive near the appliance for the connection of the power cable.

6.4 Combustion air

The appliance, during its operation, requires combustion air.

The inflow of combustion air can be obtained in the following ways:

• it can come directly from outside with direct connection to the combustion chamber (Fig. 14 - Fig. 15).
• it can come from the installation room or suitable adjacent rooms (Fig. 16)

Extraction of combustion air from outside

In this case, a possible alternative may be:

• to channel the combustion air using a coaxial pipe to expel the flue gases and extract the air (Fig. 14 - A, B = Air inlet, C, D = Flue gas outlet); in this case it is not necessary to create a classic air intake in the room.
• to connect the combustion air inlet of the appliance to the air intake using a special pipe (Fig. 15).

D A A B C Fig. 14

Architectural cross-section diagram showing a vertical wall and brick wall with directional arrows indicating movement (no text or symbols)

Extraction of combustion air in the room

Create the air intake on the wall (Fig. 16 - PA = Air Intake), and leave the appliance to withdraw the room air, making sure to connect the section of corrugated pipe on the air inlet pipe, if supplied, fixing it with the strap and folding it slightly downwards to prevent any resonance effects.

PA Fig. 16

If the rear wall of the appliance is an external wall, make a hole for the intake of combustion air at a height of about 20-30 cm from the ground, observing the dimensions on the technical data sheet in section "4.3 Technical features" on page 51.

A non-closable permanent aeration grid must be placed externally; in areas that are particularly windy and exposed to weathering, provide rain and wind protection.

Ensure that the air intake is positioned so that it won't be accidentally obstructed.

If it is impossible to create an external air intake in the wall behind the appliance (non-perimeter wall), a hole must be made in an external wall of the room where the appliance is positioned.

If it is not possible to create the fresh air intake in the room, an external hole can be created in an adjacent room provided it is permanently interconnected by means of a transfer grille.

It is forbidden to take combustion air from garages, warehouses of combustible material or places with activities at risk of fire.

If there are other heating or extraction appliances in the installation room, combustion malfunctions may occur due to a lack of combustion air. The combustion air intakes must therefore be sized correctly, in order to ensure the necessary supply of air for the correct operation of all devices.

6.5 Flue gas fitting

The appliance works with the combustion chamber at negative pressure. It is therefore essential to make sure that the flue gas evacuation is airtight (this is the responsibility of the installer).

The appliance must be connected to its own flue gas duct, not shared, and which is suitable for ensuring adequate dispersion of the combustion products into the atmosphere, in accordance with the regulations in force in the country of installation.

The components making up the flue gas ducting system must be declared suitable for the specific operating conditions and provided with CE marking.

It is mandatory to create a first vertical section measuring at least 1.5 meters to guarantee correct expulsion of the flue gases.

It is advisable to make a maximum of 3 direction changes, in addition to that resulting from the rear connection of the appliance to the chimney, using 45 - 90° bends or Tee fittings (Fig. 17).

Always use a Tee fitting with inspection cap at each horizontal and vertical change of the flue gas route (Fig. 17).

The horizontal sections must have a maximum length of 2-3 m with an upward slope of 3-5% (Fig. 17).

Anchor the pipes with suitable collars to the wall.

The flue gas fitting MUST NOT BE connected:

• to a chimney used by other generators (boilers, stoves, fireplaces, etc. ...);
• to air extraction systems (hoods, vents etc. ...) even if "ducted".

It is forbidden to install shut-off and draught valves.

MAX 2 - 3 m C > 3 - 5% MIN 1,5 m B B Fig. 17

As an additional safety measure, a threaded coupling with "R" closing cap is provided in order to connect a condensate drain pipe (Fig. 18).

Fig. 18

6.6 Roof exhaust with traditional fireplace

The chimney for the evacuation of flue gases must be made by qualified personnel in compliance with standards UNI 10683- EN 1856-1-2- EN 1857-EN 1443- EN 13384-1-3- EN 12391-1 both in terms of the dimensions and the materials used in its construction.

The flue gases can be evacuated through a traditional chimney (Fig. 19) provided the good condition and proper maintenance of the chimney has been verified. In the case of an old chimney, it is advisable to renew it using ducting.

The flue gas exhaust must be on the roof.

1 2 3 Fig. 19

1) Wind-proof cowl
2) Seal
3) Inspect

If the chimney has a larger section, it must be "intubated" with a suitably insulated steel pipe (with diameter suitable for the route (Fig. 20).

Make sure that the connection to the brickwork chimney is properly sealed.

In case of pipes that pass through wooden roofs or walls, it is recommended to use special certified ducting kits commonly available on the market.

7 INSTALLATION

7.1 General considerations

In the following sections some indications are provided to be complied with in order to obtain the maximum performance from the purchased product.

The following indications are how- ever subject to compliance with any possible national, regional and mu- nicipal laws and regulations in force in the country where the appliance is installed.

7.2 Installation configurations

It is possible to install the stove in different ways according to personal requirements:

• Coaxial pipe
  · Single-wall pipe and air intake in room
  · Single wall pipe and outside air intake

7.2.1 Coaxial pipe

It is possible to use a coaxial pipe to expel the flue gases and simultaneously recover the combustion air since the stove has already a factory configuration for this type of installation.

To achieve this:

- Connect the coaxial pipe (A) (Fig. 21).

A Fig. 21

While it is understood that it is the technician's responsibility to properly size the chimney flue based on the installation situation and the product, it is nonetheless advisable not to exceed a length of 7 metres with an 8/13 cm coaxial pipe.

7.2.2 Single-wall pipe and air intake in room

In this case the combustion air will be taken from the room.

To achieve this:

• Insert the aesthetic ring support (A) and the ring (B) (supplied with and placed inside the combustion chamber during transport).
• Connect the flue gas outlet pipe (C) (Fig. 22).

A B C Fig. 22

7.2.3 Single wall pipe and outside air intake

In this case the combustion air is taken directly from outside, from the back of the stove.

• Remove the back panel of the stove (A)
• Disconnect the flexible combustion air hose (B) at the top and bottom.
• Insert the aesthetic ring support (C) and the ring (D) (supplied with and placed inside the combustion chamber during transport) (Fig. 23)

A B C D Fig. 23

• Fit the elbow (D) (Fig. 24)
- Remove the preform (G) on the back panel (A) and insert the flexible hose (B) to connect it to an outside air intake.
- Tighten the hose (B) with the previously loosened metal hose clamp (F)
- Refit the back panel (A)
- Connect the flue gas pipe (E).

7.3 Levelling of the appliance

The appliance must be levelled with the help of a spirit level, by regulating the adjustable feet (Fig. 25).

A = Spirit level.

A The image is purely indicative. Fig. 25

7.4 Room air circulation

The stove is designed for ductable rear hot air connection.

In order to function correctly, the PRO 2 and PRO 3 models must be ducted. In the event that ducting is not foreseen, it is necessary to:

• inhibit the operation of the fans by electrically disconnecting them and appropriately insulating their terminals to avoid possible contact with metal and/or hot parts

- close the unused outlets with the special cap supplied as an accessory.

To connect the stove to the ducted heating system, connect a pipe (B) to the rear fan (A) on one side and to the air distribution outlet (C) on the other side, securing it with a hose clamp.

When the stove is used to heat two or more adjacent rooms, it is essential to encourage recirculation of the ambient air to uniform the temperature in the various rooms.

For air ducting, preferably use smooth, internally insulated pipes.

7.4.1 PRO 2

C AT A B Fig. 26

Room thermostat for rear fan control (PRO 2)

Fig. 27

It is possible to connect a room thermostat to the terminal board of the stove so that the rear fan can be switched on and off according to the temperature set on the thermostat.

To use this function, rear fan ventilation must be

set to ON.

The thermostat that controls the rear fan must be connected to terminals 5 and 6 of the terminal board in place of the bridge.

7.5 Electrical connection

Simply connect the appliance to the electrical system using the supplied plug (Fig. 28).

The electrical connection (plug) must be easily accessible after appliance installation as well.

If the power supply cable is damaged it must be replaced by the technical assistance service or a qualified technician in order to prevent any risk.

Diagram showing a hand holding a pen near a screen with two circular objects, labeled Fig. 28 (no text or symbols on the diagram itself)

The system must be equipped with an earth connection and a differential switch in compliance with the laws in force.

The flue gas evacuation duct must be equipped with its own earth connection.

7.6 Fuel optimisation

Excellent fuel depends on different factors (type of installation, operating and maintenance conditions, type of pellets, etc.)

Upon first ignition, the stove can be regulated for optimum combustion performance.

Generally speaking, if at the end of combustion, there is a lot of residue in the burn pot, you should change the combustion configuration (by increasing the value) until you find the best solution.

Refer to function "(14) Combustion" of the use and functionality manual.

Depending on the type of installation it is necessary to set up the ideal configuration for correct operation of the appliance.

There are two possible configurations:

Description Configuration

Room probe (default) 1
Room thermostat 2

8.1 Configuration 1 - Room probe

Fig. 29

Configuration 1 is the default configuration for this appliance. In this case it is not necessary to make any changes.

The appliance leaves the factory with the room probe already connected to the terminals and positioned on the rear panel (Fig. 29).

It is possible to place the room probe in another place to detect the desired room temperature.

Set configuration 1 to switch the appliance on and off either manually or according to a program.

The appliance modulates the power according to the room temperature read by the room probe placed on the stove itself.

You can set the "Eco-mode" function to have the appliance switch off or on again according to the room temperature set.

The antifreeze function can also be set in this configuration.

It is important to check that the appliance is set to Configuration 1.

This configuration can also be used to switch the appliance on and off manually or in a programmed way (with the Timer function active).

8.2 Configuration 2 - Room thermostat

6 1 22.15 20.3 °C 6 5 4 3 2 1 Fig. 30

In configuration 2, the appliance is controlled by a external thermostat (or programmable thermostat) (not supplied), which switches the appliance on and off depending on the set temperature (Fig. 30).

When the temperature is satisfied, the thermostat opens the circuit and switches off the stove. The stove switches back on automatically when the temperature falls below the value set on the external thermostat (closed circuit).

This configuration can also be used to switch the appliance on and off manually or in a programmed way (with the Timer function active); to do this it is necessary to put the thermostat on terminals 1 and 2 and remove the bridge.

If the thermostat allows scheduled programming, to avoid overlapping operation time slots, it is advisable to deactivate the appliance timer by setting it to OFF.

In this configuration the appliance turns off when the external thermostat is satisfied, or it will modulate the power (to keep consumption to a minimum) when the set room temperature is reached.

9 FIRST IGNITION

The first ignition must be carried out by the installer.

9.1 Pellet loading

- Open the pellet loading hatch.

- Load the pellets.

Technical line drawing of a device interior with granular material being inserted, labeled as Fig. 32 (no text or symbols on the diagram itself)

- Close the hatch.

The appliance, which is the subject of this manual, is an indoor domestic heating stove, powered exclusively by wood pellets with automatic loading.

9.2 First start up

During the first ignition of the stove, make sure the rooms are properly ventilated as unpleasant odours or fumes may be generated due to the evaporation or drying of certain materials used. This phenomenon will gradually disappear.

Connect the appliance to the mains, operate the power switch on the back of the appliance by turning it to "I".

Fig. 33

If the connection is correct, the appliance emits a series of intermittent noises and the display lights up.

See the display manual.

10 CLEANING AND MAINTENANCE

Cleaning can be carried out by the user.

Maintenance operations must be performed by an authorised technical assistance centre.

Before performing any maintenance operation, take the following precautions:

• Ensure that all appliance parts are cold.
• Make sure that the ashes are completely extinguished.
• Use personal protective equipment provided for by Directive 89/391/EEC.
• Make sure that the general line switch is turned off.
• Make sure that the power supply cannot be accidentally reactivated. Remove the plug from the wall socket.
  • Always use appropriate equipment for maintenance.
• Once maintenance or repair operations have been completed, before putting the appliance back into service, reinstall all the safety guards and reactivate all the safety devices.

(*) At least once a year or every 4000 kg of pellets burned.

10.2 Routine cleaning

10.2.1 Cleaning the inside of the firebox

Daily or before each ignition, it is necessary to check that the burn pot is clean to ensure the free flow of combustion air from the holes of the burn pot itself.

Vacuum the ash accumulated in the burn pot (Fig. 35).

Remove the ash from the combustion chamber as the salts present cause corrosion of the metal. In addition, the ash could block the passage of air, varying the development of the flame which, if it approaches the glass, would increase corrosion.

After cleaning the burn pot, remove it from its housing and clean the space where it is contained

The image is purely indicative. Fig. 34

If necessary, remove the ash drawer and empty it, making sure to remove any residue in the compartment where it is contained (Fig. 36).

Using an ash vacuum can simplify the cleaning operations

The image is purely indicative. Fig. 35

10.2.2 Cleaning the glass

This is done with a damp cloth or damp paper towel passed through the ash (Fig. 37).

Rub until the glass is clean.

Do not clean the glass while the stove is on and do not use abrasive sponges.

Do not use solvents, acids or detergents, liquid detergents or aggressive products.

10.3.2 Door safety

In order to guarantee the correct and safe operation of the fire box door, it is necessary to lubricate the springs of the closing mechanism, which may be located at the hinges (A) or at the door closing latch (B).

A B Indicative image Fig. 38

10.3.3 Maintenance of the flue gas system

If there are horizontal sections, it is necessary to check and remove any deposits of ash and soot before they obstruct the passage of fumes.

The incrustations inside the flue affect the optimum forced draught. When they reach a thickness of 5-6 mm, with high temperatures and sparks, they can ignite with easily imaginable consequences both for the flue and for the house.

In the event of failure to clean or inadequate cleaning the appliance may have operating problems including:

• bad combustion;
• blackening of the glass;
• blockage of the burn pot with accumulation of ash and pellets;
• deposit of ash and excessive deposits on the exchanger with consequent poor performance.

10.3.4 Appliance maintenance

To be carried out at least once a year, or every time the appliance signals maintenance request.

During the maintenance operation, the technician must:

• clean the flue gas transit area thoroughly and completely;
• check the condition and tightness of all the seals;
• check the condition of all internal components and make sure they are clean;
• make sure the flue gas outlet connection is sealed and clean;
• remove any deposits of pellet residues in the tank;
• check that there are no pellets or pellet residues in the appliance installation space;
• check the correct operation of the appliance;
• reset any warnings or alarms.

The Ground Truth image displays a single, solid horizontal line, which is a stylistic or background element (like a rule line on paper). According to Rule 2, such lines must be ignored by the OCR result. The provided OCR content is "____", which consists of underscores. Underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. Outputting underscores for a solid line constitutes an error, as it misrepresents the visual element and violates the instruction to ignore stylistic lines. Therefore, the OCR result is inconsistent with the Ground Truth.

[Non-Text]

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated placeholder underscores where none should exist in the GT. Hence, the OCR result is inconsistent with the Ground Truth.

The image contains no text. The horizontal lines are stylistic or background elements and must be ignored according to the rules. Therefore, the correct OCR output is empty.

Underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. Outputting underscores for a stylistic line is incorrect because it misinterprets the line as a fill-in-the-blank placeholder. Since the OCR output incorrectly rendered a stylistic line as underscores (which should be ignored), this violates the rule. Therefore, the OCR result is inconsistent with the Ground Truth.
