ENGLISH
CHIMNEY FLUE
The sizing, installation and connection of the chimney ue to the boiler must be carried out by an authorised company of master
chimney sweepers according to European, national and local regulations.
The ue must develop a sucient draught to convey and transport combustion smoke outdoors at all operating speeds. It is important to
have an adequately sized self-sucient ue for the boiler to operate correctly.

TO STABILISE THE DRAUGHT IN THE FLUE, IT IS NECESSARY TO INSTALL AN ADDITIONAL AUTOMATIC DRAUGHT REGULATOR
ON THE FLUE PIPE OR IN THE CHIMNEY.
THE QUALITY OF COMBUSTION, THE HEAT OUTPUT AND THE SERVICE LIFE OF THE BOILER DEPEND ON THE DRAUGHT. Fireplace
draught is directly proportional to the diameter, height and coarseness of the internal wall. Smoke from another appliance must not ow into
the ue connected to the boiler.
WARNING:AS REGARDS THE CONNECTION TO THE CHIMNEY FLUE AND FLAMMABLE MATERIALS, REFER TO THE European,
national and local regulations.THE FLUE MUST BE AT A SUITABLE DISTANCE FROM FLAMMABLE OR COMBUSTIBLE MATERIALS
BY MEANS OF ADEQUATE INSULATION OR AN AIR GAP.
SMOKE DUCT
THE HEAT GENERATOR OPERATES WITH NEGATIVE PRESSURE AND IS EQUIPPED WITH AN OUTPUT FAN FOR SMOKE EXTRACTION. THE
GENERATOR MUST ONLY HAVE ONE DISCHARGE SYSTEM. IT IS NOT PERMITTED TO HAVE A FLUE THAT IS SHARED WITH OTHER DEVICES.
Components of the smoke extraction system must be selected based on the type of device to install and according to:
• UNI/ TS 11278 in the case of metal replaces, with special reference to the designation.
• UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, .-UNI EN 1806: in the case of non-metal replaces.
• The smoke duct must be as short as possible.
• A T-tting must be installed with a condensation collection cap at the bottom of the vertical section. The vertical duct can either be
inside or outside the building. If the smoke duct is installed inside an existing ue, it must be certied for solid combustion.
• If the smoke duct is outside the building, it must always be insulated.
• It must be possible to inspect all sections of the smoke duct.
• Inspection openings must be provided for cleaning.
IT IS MANDATORY TO PROVIDE A“T” FITTING WITH A CONDENSATE COLLECTION CAP
AT THE BASE OF THE VERTICAL SECTION SMOKE SUCTION FAN OUTLET.
CONNECTION MUST BE CARRIED OUT WITH STABLE, STURDY PIPES THAT COMPLY WITH ALL STANDARDS AND REGULATIONS IN FORCE
AND ACCORDING TO THE PROVISIONS OF LAW, AND SECURED WELL TO THE FLUE.
THE INTERNAL DIAMETER OF THE CONNECTION PIPE MUST CORRESPOND TO THE EXTERNAL DIAMETER OF THE SMOKE OUTLET
OF THE APPLIANCE.
CHIMNEY POT
Flue draught also depends on the suitability of the chimney pot.
CHIMNEY POTS MUST MEET THE FOLLOWING REQUIREMENTS:
• Have a useful output section of more than double the length of the replace/pipe system into which it is inserted
• Be constructed in such a way that rain and snow cannot penetrate into the replace/pipe system
• Be constructed in such a way that even in the case of winds from all directions and with any inclination, the evacuation of combustion
products (windshield terminal) is ensured.

ENGLISH
OBLIGATIONS OF THE SYSTEM OPERATOR
The operator is required to:
- Always operate the system in appropriate conditions;
- Not make changes or allow others to make changes or tamper with the system;
- Read the operating instructions before starting the system;
- Have the operation of the whole system checked;
- Have the system repaired.
The system must be commissioned by the installing company (specialising in the construction of heating systems) or by an authorised La
Nordica Spa Service Centre.
This must be documented in a commissioning report.
It is necessary to check that all system components have been installed correctly and that all control and safety devices are working properly
and are correctly set.
The installer must issue the certication of the entire system installed, with instructions for operation and maintenance.
When it is delivered to the operator, the operation and maintenance of the system and of the boiler, including any additional equipment, must
be explained in detail to him/her or to the person assigned to the management of the system.
In particular, the function of the safety devices and the measures to maintain safe operation must be explained.
CHIMNEY
Before installing the system, be sure to have all the permissions required by European, national and local regulations.
The chimney and ue pipe must be designed in accordance with the technical specications of the LNK-EVO product.
When sizing and checking the ue, a draught regulator must be installed.
In order to ensure trouble-free operation when installing a new heating system, optimal chimney sizing in accordance with current regulations
is a prerequisite.
The connection to the chimney must be as short as possible.
Before installing the system, it is necessary to measure the draught and calculate the ue.
The maximum vacuum in the boiler room must not exceed 4 Pa for combustion air supplied via pipes.
If the combustion air is introduced through an opening in the outer wall, a pressure dierence of 3 Pa must not be exceeded.
All information required for the calculation of the ue can be found in the technical specications of the respective boiler type.
Calculated chimneys smaller than the ue gas inlet (150mm) of the boiler are not allowed.
DRAUGHT REGULATOR
To ensure the correct operation of LNK-EVO wood boilers, it is necessary to use a draught regulator.
1111

ENGLISH
If the system is not commissioned by legally qualied and authorised personnel, the warranty will be void.
The prerequisites for trouble-free operation are:
- Periodic cleaning of the boiler
- Good fuel quality;
- Constant ue draught;
- A sucient supply of fresh air of at least 4 m³/h for 1 kW in the installation room;
- Built-in and regulated draught regulator.
PERMITTED FUELS
Only natural wood in the form of split logs, including the bark, can be burned in the LNK-EVO boiler.
IT IS FORBIDDEN TO USE PALLETS, PLANKS AND SIMILAR, BECAUSE THEY HAVE BEEN PRETREATED WITH PAINT.
THE USE OF OTHER NONPERMITTED FUELS MAY DAMAGE THE BOILER. IN THIS CASE, NEITHER THE MANUFACTURER NOR THE SUPPLIER
SHALL BE HELD RESPONSIBLE.
Note: the logs must have a residual moisture between 12% and 18%. For wood with low residual moisture (12%), logs with a large diameter
(> 10 cm) should be used.
For wood with high residual moisture (18%), logs with a small diameter (6-8 cm) should be used. Glued, painted or similar materials
must never be used in this boiler!
FUEL
The recommended type of fuel is dry wood having a diameter of 8-15 cm, aged for at least 2 years, with a moisture content not
exceeding 15-18%, with a heat output of 4.7 kW/kg and a log length of 50 cm.
The dimensions of the fuel to use can be found in the “TECHNICAL SPECIFICATIONS” paragraph.
Basic data regarding wood.
The graph below indicates the interdependence between the water content and heat output of the fuel. The useful energy volume of
the wood drops signicantly in relation to the amount of water.
Boilers are not suitable for burning wood with a moisture content of less than 12% because, below this value, gasication becomes
uncontrollable.

SAFETY HEAT EXCHANGER AND AUTOMATIC THERMAL DISCHARGE VALVE DSA
The safety heat exchanger of the boiler must be equipped with a tested and certied thermal discharge valve.
If the temperature of the boiler exceeds 95°C, the cold water supply is activated to prevent the boiler temperature from rising even more.
The water side connection can be made only by a qualied technician, who must make sure that the water supply is sucient and meets the
specications indicated below.
DOMESTIC WATER SYSTEMS ARE NOT ALLOWED, ONLY PUBLIC WATER SYSTEMS ARE ALLOWED.
The pH of the drinking water must be greater than or equal to pH 7.4. If this value is not reached, the warranty is invalidated. The
water hardness test must be provided to the manufacturer on request.
The thermal discharge valve DSA must be installed at the outlet of the safety heat exchanger. This applies even if the manufacturer of the
thermal discharge valve has indicated other installation positions.
It is necessary to make sure that there is a constant water pressure of at least 2 bar.
In the event of problems with the water pressure, the system must be put out of service.
It must not be possible to block the inlet and outlet lines!
The inlet and outlet lines must be visible and accessible. The section of the line to and from the safety heat exchanger must have a nominal
width of at least 15.
THE SAFETY HEAT EXCHANGER MUST NEVER BE USED FOR DOMESTIC HOTWATER PRODUCTION/HEATING.

BOILER ASSEMBLY
DISASSEMBLY / INTRODUCTION / ASSEMBLY
The product is delivered almost completely pre-assembled. Only the lever for cleaning the heat exchanger and the fan unit needs to be
installed.
DISASSEMBLY
Depending on the conditions of the room in which the boiler is installed, some parts of it may be disassembled dierently for transport
purposes.
Weight reduction:
- Removal of suspended plates;
- Removal of ceramic components and refractory panels from the upper and lower combustion chambers;
- Disassembly of the covering door;
- Disassembly of the three boiler doors;
Please note:
When disassembling components from inside the boiler, the disassembled parts must be marked in order to be able to install them quickly
and correctly.
HANDLING
The boilers are screwed onto the transport pallets for safety reasons. Loosen these screws and push the boiler o the pallet.
If the boiler needs to be lifted, there is an eyelet welded to the centre of it.
It is advisable to use a pallet truck when moving it at ground level.
Any disassembly must be adapted to the conditions of the room as well as the type of installation, so that the boiler is not damaged!
ASSEMBLY
If the boiler is installed as delivered, only the following precautions must be taken to complete the system:
- Assembly and alignment of the adjustable feet;
- Assembly of the components of the smoke exhaust system;
- Assembly of the lever for cleaning the heat exchanger (description below).
Positioning the smoke sensor
The smoke sensor is inserted in the dedicated hole above the ue ange and it is
locked in place by means of a self-tapping screw.
(See image to the side)
CONNECTING THE SMOKE EXHAUST SYSTEM
The connection between the smoke exhaust and the chimney ue must be chosen according to the chimney calculation and the congurations
that the installation room allows.
It is necessary to take into account product and installation regulations.
The smoke exhaust system and relative gasket are not pre-assembled.
This unit can be installed at dierent angles depending on the installation site and the position of the chimney.
The possible variants, vertical and 45° to the right/left, are shown below.

THIS IMAGE SHOWS ALL POSSIBLE ASSEMBLY POSITIONS WITH RELATIVE HEIGHT INDICATIONS.
In this regard, please note that installation at a 90° angle generates more heat than discharge ow.
SMOKE RETURN SHOULD BE VERTICAL OR AT AN ANGLE OF 45°.
DIRECTION OF SMOKE FAN
The forced draught smoke fan, complete with smoke tting, is supplied disassembled from the boiler.
During installation, the fan is secured to the discharge ange of the boiler together with the fastening nuts and perimeter gasket.
To facilitate installation, the smoke inlet can be installed in dierent positions, with the option to rotate it by 180°.
ATTENTION – THE SMOKE FAN IS SUPPLIED DISASSEMBLED. Insert it into the smoke duct at the back, tighten the
wing nuts completely, connect it to the power supply outlet and check if it operates correctly - suction.

Condensation-proof“T” tting with inspection plug
Installing the gasket for the smoke exhaust system
Place the gasket on the ange of the boiler. Use a screw (M8x20) to secure it.
Secure the smoke exhaust system in the desired position using 4 M8x20 screws.
