Frequently Asked Questions - PR 20 La Nordica

How do I ignite the La Nordica PR 20 boiler?

Ensure the pellet hopper is full, the burn pot is clean, and the door is closed. Press and hold the ON/OFF key (key 1) for 3 seconds. The boiler will go through ignition phases: START, PELLET LOADING, IGNITION, PREPARATION, then WORK.

What type of pellets should I use?

Use class A1 pellets certified to ISO 17225-2 (ENplus-A1, DIN Plus, or NF 444) with a diameter of 6 mm. Do not use expired pellets or any other material, as this will affect operation and void the warranty.

How often should I clean the burn pot?

For the PR20, clean the burn pot and combustion chamber after every 2 pallets (approx. 2100 kg) of pellet consumption. However, frequency depends on pellet quality and usage; clean more often if needed.

What does the 'Depr Alarm' mean?

The Depr Alarm indicates a depression (air pressure) problem. This can be caused by the door or ash drawer not closed properly, dirty combustion chamber or tube bundle, or a blocked flue pipe. Check and clean these components; reset the alarm by pressing the ON/OFF key for 3 seconds after 15 minutes.

How do I set the date and time?

Press key 6 to enter the menu, scroll to SETTINGS, confirm, then select DATE-TIME. Use keys 4 and 5 to adjust day, hour, minutes, date, month, and year. Confirm with key 6 and exit with key 1.

Can I connect an external thermostat?

Yes, a mechanical or digital 'normally open' thermostat can be connected to the TA clamp. The installation must be performed by a qualified technician. The STAND-BY function can be enabled to allow the boiler to switch off when the thermostat is satisfied.

What is the minimum water return temperature?

The minimum water return temperature is 55°C. An anti-condensation device (valve) is mandatory to maintain this temperature and prevent condensation.

How do I perform a first load of pellets?

With the boiler cold and OFF, ensure the hopper has pellets. Go to SETTINGS > FIRST LOAD and confirm. The auger will run continuously to fill the burn pot. To stop, press key 1 for 3 seconds.

What safety devices are included?

The PR20 includes a 3 bar safety valve, a bulb thermostat for overheat protection, a water temperature indicator, a pump control thermostat, and an automatic cut-off thermostat. The system also has a pressure gauge and expansion vessel.

How should I dispose of the appliance at end of life?

Do not dispose of with household waste. Separate collection is required. Contact your local council or dealer for proper disposal according to the WEEE Directive (2012/19/EU). Batteries and accumulators must also be removed and recycled separately.

ROUTINE MAINTENANCE

Based on Decree 22 January 2008 n°37 art.2, routine maintenance means interventions aimed at reducing degradation due to normal use, as well as dealing with accidental events entailing the need of first interventions, which however do not modify the structure of the system upon which one is intervening or its intended use according to the requirements laid down by the technical standards in force and by the manufacturer's use and maintenance manual.

INSTALLATION

GENERAL

The flue gas exhaust and hydraulic connections must be carried out by qualified personnel who must issue installation conformity documentation compliant with national standards.

The installer must provide the owner or person acting for him, according to the legislation in force, with the declaration of conformity, supplied with:

1) the use and maintenance manual of the appliance and of the system components (such as for example, the smoke ducts, chimney, etc.);
2) photocopy or photograph of the chimney plaque;
3) system booklet (where applicable).

The installer must ask to be issued with a receipt stating that the documentation has been provided, and must keep it with a copy of the technical documentation relating to the installation.

For installation in a condominium, prior approval from the condominium's administrator must be requested.

Where required, check the exhaust gas emissions after installation. Should a sampling point be installed, it must be airtight.

COMPATIBILITY

Do not install in rooms with a fire hazard. It is also forbidden to install it in living areas with the following characteristics:

1. where there are liquid fuel appliances with continuous or discontinuous operation that draw the combustion air into the room in which they are installed.
2. where there are type B gas appliances intended for heating, with or without domestic hot water production and in adjacent and communicating rooms.
3. where the depression measured in situ between the external and internal environment is greater than 4 Pa.

N.B.: Watertight appliances can also be installed in the cases indicated in points 1, 2 and 3 of this paragraph.

INSTALLATIONS IN BATHROOMS, BEDROOMS AND STUDIO FLATS

Installation in bathrooms, bedrooms and studio flats is only allowed for sealed or closed hearth appliances with ducted combustion air taken from the outside.

POSITIONING AND SAFETY DISTANCES

The support surfaces and/or points must have a suitable capacity to bear the overall weight of the appliance, accessories and coverings. If the floor is made of a combustible material, we recommend using a non-combustible material to protect the front part from any burnt material which might fall during routine cleaning operations. The generator must be level to function properly. The side walls, the rear walls and the floor support surface should be made of non-combustible material.

MINIMUM DISTANCES (PELLET STOVES)

Installation next to flammable or heat-sensitive materials is permitted only if the special safety distances specified on the label at the beginning of the manual (pag.2) are observed. If the materials are not flammable, you must keep a side and rear distance of at least 100 mm (without the inserts). For products equipped with rear spacers, wall-mounting installation is permitted exclusively for the rear side.

PREPARATIONS FOR MAINTENANCE

One must also bear in mind all laws and national, regional, provincial and town council regulations in force in the country in which the appliance has been installed, as well as the instructions contained in this manual.

To carry out extraordinary maintenance operations on the product, it may be necessary to move it away from the adjacent walls. This must be done by a technician authorised to disconnect the combustion product evacuation ducts and then reconnect them. For heaters connected to the hydraulic system, the connection between the system itself and the product must be made in such a way that, when an authorised technician is about to carry out extraordinary maintenance operations, it is possible to move the heater at least 1 metre away from the adjacent walls.

INSTALLING INSERTS

When installing inserts, access must be prevented to the internal parts of the appliance and it must not be possible to access live parts during extraction operations.

Any wiring, for example the power cable or room probe, must be positioned so as not to be damaged during movement of the insert and must not come into contact with hot parts. If a cavity made of combustible material is installed, we recommend taking all the safety precautions indicated by the installation standards.

VENTILATION AND AERATION OF INSTALLATION ROOMS

In case of non-airtight heater and/or installation, the ventilation must respect the minimum area indicated below (considering the highest value among those provided):

Appliance categories Reference standard	Percentage of the net opening section with respect to the appliance fumes outlet section	Minimum net opening value of the ventilation duct
Pellet stoves UNI EN 14785 - 80 cm 2
Boilers UNI EN 303-5 50% 100 cm 2

Under any condition, including in the presence of extractor hoods and/or of controlled forced ventilation systems, the pressure difference between the generator installation rooms and the outside must always be equal to or less than 4 Pa.

Extraflame®

In the presence of type B gas appliances with intermittent operation not intended for heating, they must have their own aeration and/or ventilation opening.

The air inlets must meet the following requirements:

◆ they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
◆ they must be made so as to make the maintenance operations possible;

- positioned so that they cannot be obstructed;

The clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and ventilation), as long as the flow takes place freely through permanent openings communicating with the outside.

The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a fire hazard, bathroom, bedroom or common room of the building.

FLUE GAS EXHAUST

The heat generator works in depression and is equipped with an outlet fan for flue gas extraction. There must be a single exhaust system for the generator. Using a flue that is shared with other devices is not allowed.

The components of the flue gas exhaust system must be chosen in relation to the type of appliance to be installed in compliance with:

• UNI/TS 11278 in the event of metal chimneys, with particular attention to that stated in the specification;
  ♦ UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, UNI EN 1806 in the event of non-metallic chimneys.
  The length of the horizontal section must be minimal and, in any case, no longer than 3 metres, with a minimum upward slope of 3%
  There must not be more than 4 direction changes including the one due to the use of the "T" element.
• A "T" fitting with a condensation collection cap must be provided at the base of the vertical section.
  If the exhaust is not inserted in an existing flue, a vertical section with a windproof end piece is required (UNI 10683).
  The vertical duct can be inside or outside the building. If the smoke duct is inserted in an existing flue, it must be certified for solid fuel.
• If the smoke duct is outside the building, it must always be insulated.
• The smoke ducts must have at least one airtight inlet for flue gas sampling.
• All the sections of the flue gas duct must be accessible to inspection.

- Inspection openings must be provided for cleaning.

If the generator has a fume temperature lower than 160° C+ ambient temperature caused by the high yield (contact technicians) it MUST be resistant to humidity.

A flue system that does not respect the previous points or, in general, that does not comply with the regulations, may cause condensation phenomena inside it.

CHIMNEY CAP

The chimney caps must meet the following requirements:

◆ they must have a useful outlet section no less than double that of the chimney/ducted system on which it is installed;
◆ they must be adapted in order to prevent the penetration of rain and snow in the chimney/ducted system;
♦ they must be built so that, in the event of winds coming from all directions and from any angle, the expulsion of combustion products is in any case ensured;

FOR GERMANY ONLY

The product can be connected to a shared flue (multi-connection) provided that the requirements of the regional and national regulations, amongst which DIN EN 13384-2, DIN V 18160-1, DIN 18896 and of the MFeuV-2007 (Muster-Feuerungsverordnung) are strictly complied with, and that the local chimney sweep has checked and approved the installation conditions.

INSTALLATION AND SAFETY DEVICES

The installation, relative system connections, commissioning and inspection of correct functioning must be carried out perfectly, in full compliance with Standards in force, national, regional and municipal, as well as these instructions. For Italy, installation must be carried out by professionally qualified staff (Ministerial Decree dated 22.01.08 n°37).

Extraflame S.p.A. declines all responsibility for damage to objects and/or persons caused by the system.

TYPE OF SYSTEM

• There are 2 different types of system:
• Open vessel system and closed vessel system.
• The product has been designed and built to work with closed vessel systems.

CHECK THAT THE PRELOAD OF THE EXPANSION VESSEL IS SET TO 1.5 BAR.

SAFETY DEVICES FOR CLOSED VESSEL SYSTEM

According to the UNI 10412-2 Standard in force in Italy, closed systems must feature the following: safety valve, pump control thermostat, temperature indicator, pressure indicator, automatic temperature regulation device, automatic thermal cut-off switch (safety thermostat), pump system, expansion system.

DISTANCES OF SAFETY DEVICES ACCORDING TO THE LEgISLATION

The temperature safety sensors must be on the machine at a distance no greater than 30 cm from the flow connection. Whenever the generators lack a device, those missing can be installed on the generator flow pipe, within a distance no greater than 1 m from the machine.

CHECKS WHEN STARTING for THE FIRST TIME

Before connecting the boiler:

a) Discharge the air from the system using the air vent in the boiler and activating the air discharge cycle from the display
b) wash all system piping thoroughly in order to remove any residues which might compromise the correct operation of certain system components (pumps, valves, etc.).
c) The company recommends installing a magnetic filter in the generator return, to increase the operational life of the boiler, make it easier to remove impurities and increase the overall efficiency of the system.
It is also advisable to perform an inspection using appropriate instruments, to check for any stray currents that may cause corrosion.
d) Check that the flue has adequate draft, is not narrowed and that other appliances do not discharge into the flue. This is to prevent unexpected power increases. Only after this check can the flue fitting be mounted between the boiler and the flue. It is advisable to check the fittings with pre-existing flues.

ANTI-CONDENSATION DEVICE (MANDATORY)

It is mandatory to create a suitable anti-condensation circuit, which guarantees a return temperature of the unit of at least 55° C. The anti-condensation valve, for example, is used in solid fuel boilers as it prevents the return of cold water in the exchanger. A high return temperature improves efficiency, reduces the formation of condensation from the fumes and extends the service life of the generator. The manufacturer recommends using the 55° C model with 1" hydraulic connections.

For products with PWM* pump control, installation is considered equivalent to the creation of a suitable anti-condensation circuit in cases where:

• the heat generator pump is the only one in the system, or
• between the heat generator and the system there is a plate heat exchanger, or
  between the heat generator and the system there is a hydraulic compensator or an inertial storage device (buffer)

FOR CORRECT GENERATOR OPERATION, THE HYDRAULIC SYSTEM PRESSURE MUST BE BETWEEN 0.6 AND 3 BAR.

PELLETS AND LOADING

Pellets are made by subjecting wood shavings i.e. the rejects of pure unpainted wood from sawmills, carpentry products and products from other activities connected to wood working and transformation, to very high pressures.

This type of fuel is fully ecological as no glues are used for its compaction. In fact, pellet compactness is guaranteed over time by a natural substance found in wood: lignin.

In addition to being an ecological fuel, making best use of wood residue, pellets also have a series of technical advantages.

While wood has a calorific value of 4.4 kWh/kg (with 15% moisture, therefore after approximately 18 months of curing), that of pellets is 5 kWh/kg.

Pellet density is about 650 kg/m³ and water content is equal to 8% of its weight. For this reason pellets do not need to be cured to obtain a sufficient heat yield.

The pellets used must be class A1 certified according to standard ISO 17225-2 (ENplus-A1, DIN Plus or NF 444 of the following category: "High quality NF biocombustible wood pellets").

UNI EN 303-5 with the following characteristics: water content ≤ 12%, ash content ≤ 0.5% and lower calorific value >17 MJ/kg (in the case of boilers).

The Manufacturer recommends using pellets with a diameter of 6mm with its products.

PELLET STORAGE

To guarantee combustion without problems, the pellets must be kept in a dry place.

Open the tank lid and load the pellets using a scoop.

THE USE OF EXPIRED PELLETS OR ANY OTHER MATERIAL WILL AFFECT THE FUNCTIONALITY OF YOUR GENERATOR AND MAY LEAD TO THE TERMINATION OF THE WARRANTY AND CESSATION OF ANY ACCOMPANYING RESPONSIBILITY ON THE PART OF THE MANUFACTURER

DO NOT USE ANY fLAmMABLE LIQUIDS FOR IGNITION! DO NOT ALLOW THE BAG OF PELLETS TO COmE INTO CONTACT WITH THE BOILING HOT STOVE DURING THE FILLING PHASE! IN THE EVENT OF CONTINUED FAILURE TO LIGHT, CONTACT AN AUTHORISED TECHNICIAN.

NO IGNITION

THE APPLIANCE mAY FAIL TO LIGHT BECAUSE THE AUGER IS EmPTY AND NOT ALWAYS ABLE TO LOAD THE BURN POT FAST ENOUGH WITH THE PELLETS NEEDED FOR NORmAL IGNITION. IF THE PROBLEM OCCURS AFTER ONLY A fEW MONTHS OF OPERATION, CHECK THAT THE ROUTINE CLEANING DESCRIBED IN THE STOVE HANDBOOK HAS BEEN CARRIED OUT CORRECTLY

OPERATION AND LOGIC

IGNITION

Once the points listed previously have been checked, press key 1 for three seconds to ignite the stove. 15 minutes are available for the ignition phase. After ignition and having reached the control temperature, the stove interrupts the ignition phase and passes to STARTING.

PREPARATION

During the start-up phase, the stove stabilises combustion, increasing it progressively, to then start ventilation and pass on to WORK.

WORK

During the work phase, the stove reaches the set power set; see following item.

SET POWER

Set the operating power from 1 to 5 (using keys 2 and 3).

Power 1 = minimum level - Power 5 = maximum level.

SET H2O

Set the boiler temperature from 65 to 80°C (using keys 4 and 5).

PUMP OPERATION

The pump is activated when the internal water temperature reaches 60° C. Since the pump is always in operation above 60° C, it is advisable to keep a heating area always open so that the product operates in a more homogeneous manner and in order to prevent stoppages due to overtemperature. This area is usually called "safety area".

BURN POT CLEANING

At preset intervals, the generator cleans the burn pot, turning the machine off.

When the cleaning phase is finished, the generator will re-start automatically and continue the working phase, returning to the selected power level.

BLOW

During the working phase, the stove has an internal timer, which after a pre-set period of time cleans the burn pot.

This phase is shown on the display, it lowers the stove power level and increases the flue gas exhaust motor for a programmed period of time. When the cleaning phase is finished, the stove will re-start automatically and continue the working phase, returning to the selected power level.

MODULATION and H-OFF

As the water temperature approaches the set point, the boiler starts to modulate automatically bringing itself to the minimum power. If the temperature increases beyond the set point, it will automatically switch off indicating H-OFF, and will automatically go back on when the temperature drops below the set point.

SWITCH-OFF

Press key 1 for three seconds.

Once this operation has been performed, the appliance automatically enters the switch-off phase, blocking the supply of pellets.

The flue gas exhaust motor and the hot air flow motor will remain on until the stove temperature has dropped below the default parameters.

REIGNITION

The stove can only be re-ignited automatically or manually when the cooling cycle conditions and the preset timer have been satisfied.

IT IS PROHIBITED TO USE THE APPLIANCE WITHOUT THE PARTITION AND/OR FLAME GUARD (SEE FIGURE ON SIDE). REMOVAL WILL COMPROMISE THE SAFETY OF THE PRODUCT AND RESULT IN THE IMMEDIATE NULLIFICATION OF THE WARRANTY PERIOD. IN THE CASE OF WEAR OR DETERIORATION, REQUEST AFTER-SALES ASSISTANCE TO REPLACE THE PART (REPLACEMENT IS NOT COVERED BY THE WARRANTY AS THE COMPONENT IS SUBJECT TO WEAR).

STAND-BY - ADDITIONAL THERMOSTAT

N.B.: INSTALLATION MUST BE PERFORMED BY AN AUTHORISED TECHNICIAN

It is possible to control the temperature of a room adjacent to the room where the stove is positioned; simply connect a thermostat following the procedure described in the following section (it is advisable to place the optional mechanical thermostat at a height off the ground equal to 1.50 m). Stove operation with the external thermostat connected in the clamp TA can be different depending on the activation or deactivation of the STAND-BY function.

By factory default, the clamp TA is jumpered, therefore it always has closed contact (on request).

ADDITIONAL THERMOSTAT FUNCTIONING WITHSTAND-BY ACTIVE

When the STAND-BY function is active, the STBY icon will be on. When the contact or external thermostat is not satisfied (open contact / temperature reached), the stove will switch off. As soon as the contact or external thermostat switches to the "not satisfied" status (closed contact / temperature to be reached) it will re-ignite.

NB: stove operation depends on the temperature of the water inside the stove and relative factory setting restrictions. If the stove is in H-OFF (water temperature reached), any additional contact or thermostat request will be ignored.

ADDITIONAL THERMOSTAT OPERATION WITHSTAND-BY DEACTIVATED

When the STAND-BY function is not active, the STBY icon will be off.

When the contact or external thermostat is satisfied (open contact / temperature reached), the stove will go to minimum. As soon as the contact or external thermostat switches to the "not satisfied" status (closed contact / temperature to be reached) the stove will start to work again at the pre-set power.

NB: stove operation depends on the temperature of the water inside the stove and relative factory setting restrictions. If the stove is in H-OFF (water temperature reached), any additional contact or thermostat request will be ignored.

ADDITIONAL THERMOSTAT INSTALLATION

• A mechanical or digital thermostat with a "normally open" input is required.
• Remove the plug from the socket.
  Using the figure as a reference, connect the two thermostat cables (clean contact - no 230 V!).
• Connect the power to the stove again.

TO ACTIVATE STAND-BY, REFER TO THE "SETTINGS" CHAPTER

CHRONO

This function allows stove ignition and switch-off to be automatically programmed.

The factory setting for CHRONO is off.

The chrono allows the programming of 4 time slots per day, which can be used every day of the week.

For each time slot, it is possible to set ignition and switch-off times, specific days of application, desired temperature and set power.

Current day and time settings are essential for the correct operation of the Chrono.

Recommendations

Before using the chrono function, you must set the current day and time, so check that you have followed the points listed in the sub-chapter "DATE-TIME". To use the chrono function correctly, it must not only be programmed, but also enabled. The 4 time slots can be overlapped using the ignition and switch-off time settings. In this way, it is possible to create a combination of time slots with different temperatures and power levels, without changing the status of the stove.

N.B.: in the case of overlapping time slots, the stove will remain on until the last switch-off time.

ROUTINE MAINTENANCE PERFORMED BY QUALIFIED TECHNICIANS

Routine maintenance must be performed at least once a year.

Given the generator uses pellets as solid fuel, it requires annual routine maintenance, which must be performed by a Qualified technician, using only original spare parts.

Failure to comply may jeopardise safety of the appliance and invalidate the warranty conditions.

By observing the cleaning schedule reserved to the user described in the use and maintenance manual, the generator will be guaranteed correct combustion over time, thus preventing any faults and/or malfunctions which may require subsequent technical assistance. Requests for routine maintenance are not covered by the warranty.

DOOR, ASH DRAWER AND BURN POT GASKETS

The gaskets ensure the proper sealing of the stove and therefore its proper operation.

They must be periodically checked and immediately replaced if worn or damaged.

These operations must be carried out by a qualified technician.

CONNECTION TO THE FLUE

Annually, or in any case each time the flue pipe needs to be vacuumed and cleaned. If there are horizontal sections, the residue must be removed to prevent it from obstructing the flow of fumes.

SHUT-DOWN (END OF SEASON)

At the end of each season, before turning the stove off, it is advisable to completely empty the pellet hopper, removing any pellet residue and dust with a vacuum cleaner.

IT IS ADVISABLE NOT TO DISCONNECT THE HEAT GENERATOR FROM THE ELECTRICAL POWER SUPPLY IN ORDER TO ALLOW THE PUMP TO PERFORM THE NORMAL ANTI-BLOCKING CYCLES.

Routine maintenance must be performed at least once a year.
