Pellet properties
The appliance has been tested with all types of pellets available on the market. The pellets must have the following properties:
-Diameter 6 mm.
-Maximum length 35 mm.
-Maximum humidity content 8 –9 %.
-100% wood. Totally additive-free.
-Maximum ash residue 1.1 %.
To obtain good performance from the appliance, we recommend using good quality pellets. Pellets should be poured into the tank using a shovel,
and not directly from the bag.
Good-quality pellets should have the following properties:
-Constant diameter cylinders with a smooth and shiny surface;
-There should not be a lot of sawdust inside the packaging;
-After grabbing a bunch of pellets and placing them into a container filled with water, good-quality pellets will sink and poor-quality ones will tend to
float;
-The quality certification data, in particular conformity to international standards such as EN14961-2, DIN 51731 and O-NORM M7135, should be
indicated on the packaging;
-The packages should be intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value and increases the amount of
flue gases expelled, but also causes swelling of the product which may create problems with the appliance.
The production of pellets must be compliant with some international standards (such as EN14961-2, DIN 51731 and O-NORM M7135) which establish
the minimum values for quality checks on pellets. To facilitate the right choice of the combustible material you can find below one of the most common
certification marks identifying the quality of the pellets:
The use of poor-quality pellets or any other material can damage the appliance operation, voiding the warranty and exempting the
manufacturer from all liability.
In order to guarantee trouble-free combustion, the pellets must be stored in a dry place.
REQUIREMENTS OF THE PLACE OF INSTALLATION
Positioning
The initial phase for best installation of the appliance is to determine its optimum location; the following elements need to be considered:
-The possibility of creating an external air vent;
-The possibility of creating a straight flue, preferably coaxial to the outlet of the appliance;
-Proximity to the main water drain and/or the boiler (if one already exists);
-Proximity or ease of connection to the water system;
-Ease of access for cleaning the appliance, the flue gas exhaust pipes and the flue.
The unit must be installed on a floor with a suitable load capacity. If the existing building does not fulfil this requirement appropriate measures (e.g.
load distribution plate) must be taken.
The minimum safety distance from flammable materials must be at least 200 mm from the sides and 100 mm from the back of the appliance.
The installation must guarantee easy access for cleaning the appliance, the flue gas exhaust pipes and the flue, and any subsequent maintenance
operation by the Authorised technical assistance centre.
Once you have found the best location for the appliance, position it following the instructions given below.

CS.ECO-TFT.IST-1-EN / Rev 1.0 ENGLISH
The appliance must not be installed in small rooms, bedrooms, bathrooms or in areas with an explosive atmosphere.
Spaces around and above the appliance
The figure below shows the minimum distances from walls or other not-easily-removable furniture, that need to be taken into consideration when
positioning the appliance.
Any shelves or false ceilings mounted above the appliance must be at least 80 cm away from the top part of it.
Furniture and movable objects made from flammable materials must be positioned at least 20 cm from the side surfaces of the appliance; these objects
must be moved when performing maintenance on the appliance.
Protect all structures that can catch fire against the radiated heat of the fire.
Any extra intervention by the Authorised technical assistance centre, which requires the appliance to be disconnected from the system,
will not be covered under warranty as described in the chapter “Standard Warranty Conditions”.
External air intake
During operation, the appliance takes in air from the environment in which it is installed; It is therefore essential that this air is replaced through an
external air vent. The absence of the air vent may affect the flue draught and therefore the combustion and the safety of the appliance.
Therefore, it is mandatory to install an external air vent with a minimum completely free passage of at least 80 cm2(round hole with minimum
diameter of 15 cm protected with a special fixed large mesh grille).
If it not possible to put the external air vent in the same room as where the appliance is installed, this hole can be made in an adjoining room as long
as this room communicates permanently, by means of a transit hole (15 cm minimum diameter).
The hole must be protected externally with a fixed grille. The protective grille must be checked periodically to ensure that it is not obstructed, thereby
impeding the passage of air. Therefore, keep the air vents clear of obstructions.
The UNI 10683 Standard FORBIDS the drawing of combustion air from garages, warehouses storing combustible materials, or from business premises
with a fire hazard.
If there are other heating or extraction devices inside the room, the air vents must guarantee a sufficient amount of air for properly operating all the
devices.
Only sealed appliances (e.g. C type gas appliances, according to the UNI 7129 Standard) or appliances that do not cause a lower pressure compared
with the external environment can pre-exist or be installed in the place where the appliance is installed.
Extractor fans can cause malfunctions to the appliance if used in the same room.
Smoke ducts and connection to the flue
The flue is an essential element for the efficient operation of the appliance. The flue must have the minimum cross-sectional dimensions stated in the
appliance’s technical specifications (120 mm). Each product must be equipped with its own flue, without other adjoining elements (boilers, chimneys,
stoves, etc.). The flue dimensions are closely related to its height, which must be measured from the appliance flue gas outlet to the base of the stack.
In order to guarantee adequate draught, the surface of the chimney flue outlet must be double the flue cross-section. The discharge pipe for combustion
products generated by the forced draught device, must comply with the following requirements:
-It must seal off the combustion gases, as well as being waterproof and suitably isolated and insulated in relation to the conditions of use (refer to
UNI 9615);
-It must be made of suitable materials capable of withstanding normal mechanical stress, heat, and the effects of combustion gases and
condensate, if any;
-It must go upwards after the vertical section, for the entire remaining part, with a minimum gradient of 5%. The sub-horizontal section must not
be longer than ¼ of the effective height H of the flue or chimney, and must not be longer than 2,000 mm;

-It must preferably have a round internal cross-section: square or rectangular cross-sections must have rounded corners with radius not inferior to
20 mm;
-It must have a constant, free and independent internal cross section;
-Rectangular cross-sections must have a maximum ratio of 1.5 between the sides;
-It must be insulated to prevent the fumes from cooling and condensate from forming;
-Flue gas pipes (for the section from the appliance to the flue inlet) must be mounted using parts made from non-combustible materials capable
of withstanding combustion by-products and their potential condensate (it is strictly forbidden to use aluminium flues);
-It is forbidden to use fibre-cement pipes to connect the appliance to the flue;
-Flue gas pipes must not pass through rooms in which the installation of combustion devices is prohibited;
-The flue gas pipes must be assembled in such a way as to guarantee adequate sealing of flue gases when the appliance works in negative-
pressure conditions;
-It is forbidden to install horizontal sections;
-It is forbidden to use counter-sloping elements;
-The flue gas pipe must allow for the recovery of soot or be cleanable, and must have a constant cross-section;
-It is forbidden to allow other air intake pipes and system pipes to transit inside the flue gas pipes, even if they are over-sized.
FURTHER SPECIFICATIONS TO BE CONSIDERED
-The appliance works with the combustion chamber in negative pressure and the flue pipe under pressure; it is essential that the flue gas
outlet is hermetically sealed.
-The flue pipes inside the installation room must be made of a suitable material (see applicable regulations) and equipped with sealing gaskets
with a minimum diameter of 120 mm.
-The pipes must have a double wall (thermally insulated) or be suitably insulated with rock wool. The maximum temperature of the flue
pipe inside the room must not exceed 70°C.
-IT IS MANDATORY TO HAVE AN INITIAL VERTICAL SECTION OF AT LEAST 0.5 M IN ORDER TO GUARANTEE CORRECT FLUE GAS
DISCHARGE.
-Every direction change must be carried out with a T-shaped fitting and inspection cap. The pipes must be smoketight by means of special seals
capable of withstanding temperatures of up to 250°C. Attach the pipes to the wall with special collars to prevent possible vibrations.
-IT IS STRICTLY FORBIDDEN TO INSTALL DRAUGHT REGULATION VALVES (BUTTERFLY VALVES).
If the flue is old or too large (internal diameter greater than 15 cm), it must be ducted using a stainless steel pipe that is suitably insulated (with rock
wool or vermiculite) and sized according to the route. The connection to the flue must be appropriately sealed.
When assembling the flue, there must be no more than 4 direction changes.

CS.ECO-TFT.IST-1-EN / Rev 1.0 ENGLISH
Chimney
The chimney is a device crowning the flue, used to ease dispersion of combustion products.
It must satisfy the following requirements:
-It must have a usable outlet cross-section which cannot be smaller than double that of the flue onto which it is inserted;
-It must be shaped in such a way as to prevent rainwater or snow from entering the flue;
-It must be built in such a way as to ensure the discharge of combustion by-products even in the event of winds from every direction and
inclination.
The outlet height (where height refers to the top of the flue, regardless of any chimney stacks) must be outside of the so-called reflux zone, in order to
prevent the formation of counter-pressures preventing the free discharge of combustion by-products into the atmosphere.
It is therefore necessary that the minimum heights - indicated in the following diagrams - are observed:

ELECTRICAL CONNECTION
The electric connection must only be performed by qualified staff, in compliance with all general and local safety standards.
Check that the power supply voltage and frequency correspond to 230 V –50 Hz.
The appliance’s safety is ensured when it is properly connected to an efficient earthing system.
In the electric connection to the mains power supply, include a 6 A –Id 30 mA differential trip-switch with suitable breaking load. The electric
connections, including the earth connection, must be made after shutting off the electrical system.
When completing the system, bear in mind that the cables must be laid in an unmovable manner and far from parts subject to high temperatures.
During the final wiring of the circuit, only use components with a suitable electrical protection rating. Do not pass electric cables in the immediate
vicinity of the flue gas pipe, unless they are insulated with suitable materials.
KLOVER S.r.l. declines all responsibility for injury to persons and animals or damage to objects due to failure to connect the appliance to
earth or to comply with IEC specifications.
Control of a possible three-way motorized valve for DHW system management
The pellet appliance is equipped as standard with a control for a possible 3-way motorised valve to be installed on the domestic water circuit based
on the selected system type (see “System configuration”). On the terminal block of the appliance’s left-hand technical compartment there are four
inputs that can be used for controlling this valve (see also “Wiring diagram”). The four wires connected to the terminal block have different colours,
precisely:
-Blue wire = 3-WAY VALVE COMMON (Neutral 230 V)
-Black wire = DOMESTIC WATER SIDE (Live 230 V with DHW demand)
-Brown wire = HEATING SIDE (Live 230 V with no DHW demand)
-Yellow/green wire = GND
Connection to the room thermostat
On the terminal block of the appliance’s left-hand technical compartment there are two bridged inputs which can be used to connect a room thermostat
that will command the operation. The operation of the room thermostat is enabled with plant types 1, 2, 3, 5 (see“System configuration”).
Listed below is the operating principle with OPEN CONTACT:
-The appliance switches directly to economy mode operation “T-AMB ECONOMY” thus minimising its operating power.
-The heating circulating pump of the appliance switches off.
-The appliance switches off with a delay set to Pr44.
The appliance will switch on again automatically if all of the following conditions occur:
-The contact of the room thermostat closes.
-If it goes below the temperature differential (SET H2O –Pr43).
-Once any cooling cycles are complete.
N.B.: if the water temperature exceeds the set threshold of 80°C (Pr50 = safety temperature), the system’s circulator pump is forcedly switched on to
ensure the disposal of excessive heat, thus avoiding high water temperatures in the boiler. For this reason, it is recommended that the heating system
is not entirely closed.
In the configuration “System type 3”, the appliance switches to economy mode and then switches off only if the “SET BOILER” temperature setting
has been reached.
WARNING: if also the external room sensor is enabled, the appliance switches to economy mode if the “SET ROOM” temperature setting has also
been reached.

CS.ECO-TFT.IST-1-EN / Rev 1.0 ENGLISH
HYDRAULIC CONNECTION
The plumbing connections must be made in a rational way using the connections on the template of the appliance. To facilitate connection of the
pipes, all plumbing attachments have been fitted to the upper part of the appliance.
The appliance can be coupled with any other boiler already installed on the system. In this case, it is essential to fit all the necessary safety devices
and shut-off valves based on the system and intended use. It is also necessary to consider all laws and national, regional, provincial and municipal
regulations of the country where the appliance is installed.
The appliance can be installed with the expansion vessel closed because it is equipped with a device for stopping fuel loading, a safety manual reset
thermostat and a sound alarm, which are activated if the temperature becomes too high.
You can install the appliance in the same room as another boiler only if this has a sealed chamber; installation must be performed in
compliance with the current regulations.
When installing the appliance, it is advisable to fit an anti-condensate mixer valve between the delivery and return pipes on the appliance’s
heating system. The anti-condensate valve must be calibrated to 55°C with a Kv value equal to or greater than 8 m3/h.
When connecting the appliance to the system, you should provide a zone that is always open (such as bathroom area) to enable the excess
heat dissipation of the water in the body of the boiler.
The maximum mains water pressure should never exceed 2.5 bar; recommended operating pressure is 1.5 bar (with the appliance in
operation).
An anti-limescale device must be installed if the water hardness exceeds 28°f. This device must be chosen on the basis of the specific
properties of the water.
TO AVOID COMPROMISING THE OPERATION AND LIFE OF THE HEAT PUMP, WE RECOMMEND INSTALLING A FILTER AND A MAGNETIC
DIRT SEPARATOR DOWNSTREAM OF THE RETURN PIPE ON THE APPLIANCE.
The appliance must be mounted exclusively by qualified personnel. Scrupulously comply with the instructions given in this guide.
The manufacturer declines any liability for damages caused due to incorrect assembly.

INITIAL START-UP
System configuration
Before commissioning the appliance, it is advisable to choose which type of system it has been connected to, by accessing “Sub-menu M09-3 –
PLANT TYPE”.
The available PLANT TYPE configurations are given below:
➢1 = Boiler connected to a heating system and (potentially) an external plate heat exchanger for the production of DHW.
Plant Type “1” involves connecting the boiler to a heating system (or centralised puffer) managed by one or more room thermostats. These are
connected to the terminal located inside the appliance’s technical compartment. The production of DHW, where required, will be achieved using a
plate heat exchanger fitted externally to the appliance and controlled by a flow switch, which is also connected to a terminal arranged on the boiler.
This device is used to bring the appliance immediately to domestic hot water power output working mode and to switch a three-way motor-driven valve
to give it priority.
➢2 = Boiler with integrated instant DHW, connected to a heating system combined with an alternative DHW generator.
Plant type “2” involves connecting the boiler with integrated instant DHW (configured model only) to a heating system managed by one or more room
thermostats. These are connected to the terminal fitted inside the appliance’s technical compartment. DHW generation is achieved via a mini storage
tank built-into the appliance. To guarantee DHW at all times, in this plant configuration it is necessary to combine an alternative DHW generator. The
combination with the alternative DHW generator is managed by a motor-driven three-way valve connected to the pellet-fired appliance: in this way,
the DHW generated by the pellet-fired appliance can be used only when the latter is running and has thus reached its working temperature.
