Airborne noise data

The sound levels in the following table are basaed on the sound measurement of an Ecompact 250.
The sound level of the individual units was pltted at the distance of 1m from the sound source.
Ambient level measurement: 33 dB.

Please note that all of the measurements were taken in-house and do not come from a certified test centre.
This data should therefore be viewed as guidance only.

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, 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 O­NORM M7135) which establish 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:

certification (example "xxx")

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.

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.

15

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

30 cm

15 cm

Any shelves or false ceilings mounted above the appliance must be at least 50 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 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 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.

Chimney and Flue pipe

The chimney is essential to the efficient operation of a Klover appliance. The chimney should be constructed according
to these instructions, the relevant BS EN regulations and Building Regulations Approved Document J.

Shape and size of chimney: A round chimney of 125mm diameter is recommended. 125mm is also the minimum
diameter which should be used. If the appliance is DEFRA Exempt then it should be connected to a 125mm chimney as
standard (assuming that the outlet is not larger than 125mm). If it is not DEFRA Exempt then a calculation according to
BS EN 13384-1:2002 must be completed if it is to be connected to a 125mm diameter chimney.
The maximum recommended round chimney diameter is 150mm.

16

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

Square or rectangular cross-sections must have rounded corners with radius not less than to 20 mm Rectangular cross­sections must have a maximum ratio of 1.5 between the sides.
The chimney must have a constant, and unobstructed, internal cross section
Under no circumstances should the chimney be of a smaller diameter than the appliance outlet.

Connecting flue pipe: Short runs of single skin flue pipe to connect to the chimney may be run in a (minimum) diameter
of 100mm (as long as this is not smaller than the appliance outlet). An analysis port should be incorporated to enable,

flue gas analysis, draught measurement and commissioning.

Existing chimneys: Existing masonry chimneys should be lined with flexible stainless steel liner and the liner should be
insulated. All connections must be appropriately sealed.
Existing chimneys must be inspected, be clear of obstruction and have been swept clean immediately before installation
of the lining system.

No shared chimneys: Each appliance must connect to its own flue. No other appliance must connect to the same flue or
chimney. No other pipes or conduits must pass through the chimney or flue.

Sealed joins and connections: The appliance works with the combustion chamber in negative pressure and the flue pipe
under positive pressure; it is essential that all joints and flue and chimney connections are sealed. Single skin and twin
wall flue pipe should incorporate silicone seals at each joint. Other connections should be sealed with a suitable sealant
(for example high temperature silicone). All seals must be able to withstand 250ºC or more.

Suitable materials: Flue and chimney products used, including fixings and components, must be made of suitable, non­combustible materials conforming to the applicable regulations.
Aluminium and fibre cement pipes are forbidden.

Orientation and initial vertical rise: The flue system should run as vertically as possible as any deviations off the vertical
can adversely affect the draw. 45º is the maximum off-vertical angle than may be used. Non-vertical sections should
make up no more than ¼ of the effective height of the flue or chimney (measured from the appliance outlet to the top of
the chimney), and must not be longer than 2,000 mm.
There should be no more than 4 bends in the system, with a tee counting as 2 bends.
Securely fix and support the system to avoid vibration and movement.
90º bends should not be used. When using the rear outlet on the appliance a 90º tee should be used with sweeping
access and debris collection space.
When using the rear outlet any horizontal run should not exceed 150mm, including the arm of the tee.
An initial vertical run of 600mm from the appliance is recommended before any change in direction.

Cleaning Access: The system must provide access so that the entire system can be swept and cleaned.

Flue pipes must not pass through rooms in which the installation of combustion devices is prohibited.

IT IS STRICTLY FORBIDDEN TO INSTALL FLUE DAMPERS/BUTTERFLY VALVES.

Heat shielding: If combustible materials are present then minimum separation distances will need to be adhered or heat
shielding will be required. Please refer to Building Regulations Approved Document J, and also these installation
instructions.

Termination/Cowl: The cowl terminates the chimney and it is recommended that an effective anti-downdraft cowl should
always be used. It must have a usable outlet cross-section no less than double that of the flue onto which it is inserted.
In must prevent rainwater or snow entry. It must be ensure the discharge of combustion by-products even in the event of
winds from every direction and inclination.

17

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

Height and draught: In order for the appliance to perform satisfactorily the chimney height must be sufficient to ensure a
draught of 12 Pa so as to clear the products of combustion and prevent smoke problems into the room.
A chimney height of not less than 4.5 m measured vertically from the outlet of the stove to the top of the chimney
should be satisfactory. Alternatively the calculation procedure given in BS EN 13384-1:2002 may be used as the basis
for deciding whether a particular chimney design will provide sufficient draught.

The outlet from the chimney should be above the roof of the building in accordance with the provisions of Building
Regulations Approved Document J diagram 17 or 18. Please see the diagram below.

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 230V – 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 srl 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 any coupled boiler

If the pellet appliance is to be coupled with a previously installed boiler in the system (e.g. wall-hung gas boiler), you
must ensure that the standard boiler stops when the pellet appliance takes over the heating of the system. The electrical
setting, which is accessible from the left-hand technical compartment, intervenes on the standard boiler when the
heating circulating pump of the pellet appliance starts up so as to avoid having two boilers operating simultaneously on
the same system. The coupled boiler is however always available for the production of domestic hot water.

The two wires fitted on the left-hand technical compartment of the appliance (blue and brown wires) will have an
output voltage of 230 V when the pellet appliance pump is working, and no voltage when the pump stops.

It is therefore necessary to connect the 2 wires to a relay that will control the Room Thermostat (R.T.) input of the
coupled boiler (see the following example).

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”). In the left-hand technical
compartment of the appliance there are four wires with fastons protected by a red seal, which can be used for controlling
the valve (see also “wiring diagram”). The four wires have different colours, and precisely:

- Blue wire = 3-WAY VALVE COMMON (Neutral 230 V)

- Black wire = SANITARY SIDE (Phase 230 V with DHW demand)

- Black wire = HEATING SIDE (Phase 230 V with no DHW demand)

- Yellow/green wire = GND

19

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

Connection to the room thermostat

On the left-hand technical compartment of the appliance there is a bridged terminal which is used to connect the room
thermostat that will command the operation. The operation of the room thermostat is enabled with system types 1, 2 and
3 (see“System configuration”).

OPERATING PRINCIPLE

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 temperature in the boiler increases due to thermal inertia until it reaches the

temperature set with “SET H2O” and displays “T-H2O ECONOMY” on its monitor.

- The appliance now switches itself off automatically if at least one of the following
conditions occurs:

- If it remains in Economy mode Operation “T-H2O ECONOMY” for a time set

on Pr44 (20 minutes as default setting).

- If it exceeds the temperature differential set on Pr43 (set as default at 5°C),

in other words if Temperature H2O > (“SET H2O” + Pr43).

- The appliance will switch on again automatically if both of the following conditions
occur:

- The contact of the room thermostat closes.

- If it goes below the temperature differential of the “SET H2O”.

If the above condition occurs during the switch-off cycle, please wait until the cycle is complete.

N.B.: If the water temperature exceeds the set threshold of 80°C (safety temperature), the circulating pump of the
system 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.

ATTENTION: In the event that the room sensor in the “Remote control” for the appliance is enabled, the appliance
switches to economy mode if the “SET ROOM” temperature setting has also been reached.

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 an audible 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-condensation mixer valve between the delivery and
return pipes on the appliance’s heating system. The anti-condensation valve should 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).

In the event of water with hardness exceeding 28 °f, an anti-limescale device must be installed. This must be
selected on the basis of the specific properties of the water.

TO AVOID COMPROMISING THE OPERATION AND LIFE OF THE HEAT PUMP, INSTALLATION OF A FILTER
AND A MAGNETIC DIRT SEPARATOR IS RECOMMENDED 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.

when it is filled for the first time. Warning: once the operation has been completed, before switching on the
appliance you should empty the accumulation of pellets deposited inside the brazier.

Menu 07 – Fireplace status

It allows for viewing the instantaneous state of the appliance, by showing the state of the various devices connected to it.
Several pages are displayed in succession. The data is reserved for Technical assistance Centre.

Menu 08 – Technical calibration

Allows you to access all data reserved for the Technical Assistance Centre. Access is protected by a password.
Unauthorised access can cause serious damage to the equipment, to things and the environment as well as personal
injuries.

Menu 09 – System type

Allows you to configure the appliance according to the type of system is has been connected to (see “System

configuration”).

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 “Menu 06 – System type”.

The available configurations are given here below:

PLUMBING LAYOUT “1” – Boiler connected to a heating system and (potentially) an external plate heat exchanger for
the generation of DHW.

Plumbing layout 1 involves the connection of the boiler to a heating system (or centralised buffer) managed by one or
more room thermostats. These are connected to the terminal provided inside the left technical compartment on the
appliance. DHW generation, where required, will be achieved using a plate heat exchanger fitted externally to the boiler
and controlled by a flow-switch. This is also connected to a terminal provided on the boiler. This serves to bring the
appliance immediately to DHW output working mode and to switch a three-way motorised valve to give it priority.

26

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

PLUMBING LAYOUT “2” – Boiler with built-in instant DHW, connected to a heating system with an additional DHW
generator.

Plumbing layout 2 involves the connection of the boiler with built-in instant DHW (prepared models only) to a heating
system managed by one or more room thermostats. These are connected to the terminal provided inside the left
technical compartment on the appliance. DHW generation is achieved via a mini storage tank built-into the appliance. It
is recommended to fit an alternative generator in order to guarantee constant DHW in this type of system. Control of this
combination is ensured by a three-way motorised valve connected to the pellet boiler. This allows the DHW generated by
the pellet boiler to be used only when it is operational and at a suitable temperature.

PLUMBING LAYOUT “3” – Boiler connected to a heating system and DHW storage boiler.

Plumbing layout 3 involves the connection of the boiler to a heating system managed by one or more room thermostats.
These are connected to the terminal provided inside the left technical compartment on the appliance. Any DHW
generation is achieved by a storage boiler fitted externally to the boiler. This is controlled by a temperature sensor
connected to the appliance.

27

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

Centralised

buffer

The three-way motorised valve, controlled by the pellet boiler, manages the heating of the system or boiler, giving priority
to the latter.
Setting “Menu 01 – Select season” to SUMMER allows you to control the storage boiler only during the summer (with the
heating system off).

PLUMBING LAYOUT “4” – Boiler connected to a centralised buffer controlled by a H2O sensor connected to the boiler.

Plumbing layout 4 involves the connection of the boiler to a centralised buffer controlled by a temperature sensor
connected to the appliance. The boiler therefore operates only at the set temperature of the centralised buffer (“SET
BUFFER” can be set using keys 1 and 2). In this type of system there are no room thermostats or three-way valves
connected to the pellet boiler.

Filling the system for the first time

After the water connection of the appliance, fill the system as follows:

- Check the seal of all piping, the expansion vessel, and the circulation pump;

- Open the “automatic air release valve” on the appliance;

- Open the system load cock (mounted on the appliance) to load the system. Gradually allow the air to come out from
the appliance through the “automatic air release valve”; optimum working pressure is 1.5 bar (when the
appliance is operating);

- Vent all radiators and any other de-aeration systems to ensure that there are no air bubbles in the system.

After installation, check the seal of all plumbing joints for the first few days of operation.
The system and the water inside the boiler can be emptied by opening the “boiler body and system drain cock” situated
on the right side of the appliance.

In intensely cold periods it is good practice to leave the heating system running. In the event of a prolonged
absence, anti-freeze must be added to the heating water or the system must be completely emptied.

In a system subject to being emptied frequently, it is essential that filling is performed with water suitably treated to
remove hardness which can give rise to scaling.

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

Pellet loading and connection to the mains power supply

Perform the following operations:

- Connect the appliance to the electrical system by using the provided cable;

- Set the “power ON/OFF switch” on the front of the appliance to “׀” (on);

- Fill the pellet tank; for the first ever ignition, to avoid wasting the time required for filling the entire screw feed channel
(this should be done every time the appliance runs out of pellets), we recommend you follow the instructions in

the “Menu 08 – Initial load”;

- Switch the appliance on by using the ignition button on the display (button 4). See the instructions below. Warning:
before switching on the device make sure that there are no pellets in the brazier; otherwise it is necessary to
empty and clean the brazier.

We recommend that you use high quality pellets so as not to impair the operation of the appliance. Damage
caused by poor-quality pellets shall not be covered by the warranty.

Do not pour pellets directly into the brazier.

Ignition cycle

Pressing button 4 (ON/OFF) for a few seconds allows you to start the ignition cycle. After a while, the display shows
“START”, and the flue gas intake device and ignition plug switch on. After a few seconds, the appliance enters a pre­load phase “PELLET P-LOAD” during which a continuous supply of pellets is loaded. After the pre-loading phase the
appliance switches to the “WAITING FLAME” phase where the pellets are loaded into the brazier at regular intervals.
When the flame is lit, the display shows the message “FIRE”. This step is used to allow the fire to spread evenly across
the brazier and burn all the unburned pellets from the previous phases. After these phases, the appliance enters the
work mode at the pre-set power value.
If the ignition fails, the display will show the alarm “NO IGNITION”. The alarm may also occur if the brazier is dirty; in

this case, clean the brazier and re-start.

Summary:

The ignition cycle can last 20/25 minutes max. and is divided into five steps:
Step 1 - START = Ignition of the flue gas extractor.
Step 2 - WAITING PREHEATING = Waiting for the plug preheating. (Not as standard settings).
Step 3 - PELLET P-LOAD = Pellet pre-load (initial continuous load) and plug ignition.
Step 4 - WAITING FLAME = Loading pellets (intermittent load) and plug operating.
Step 5 - FIRE = Plug switch-off and flame stabilisation.

The appliance switches into working mode after ignition phase at the power output set during ignition via buttons 1 and

2.

Warning: during the ignition phase and normal operation of the appliance, maintain the necessary safety
distance and do not stand in front of it.

Switch-off cycle

The appliance switches off if you press button 4 (ON/OFF) during normal operation. The display will show “FINAL
CLEANING”. The pellet loading stops and the flue gas extractor speed increases to maximum and then switches off after

the cooling of the appliance, displaying "OFF”.
If button 4 (ON/OFF) is pressed during the ignition cycle, the appliance switches to “WAITING OFF” and the appliance
will be tutned off only at the end of the entire cycle; if, however, button 4 (ON/OFF) is pressed by mistake during this
phase, you only need to press it again to delete “WAITING OFF”: the appliance will return to normal operation at the end
of the entire ignition cycle.

PROBLEMS, ALARMS, USEFUL ADVICES

Useful info…

Listed below is some important information regarding the appliance:

- It is normal for the appliance to emit a smell of paint during its first few days of operation. We recommend ventilating
the installation room during the initial start-up. For the first few days of operation we also recommend that you set the
appliance to near-maximum level.

- The boiler unit is treated with anti-oxidant paint in order to protect it against oxidation in the event of long periods of
inactivity. After initial start-up, this paint no longer preserves its original features and any wear of the paint inside the
combustion chamber should not be regarded as a manufacturing fault.

- Do not clean with water inside the combustion chamber; any oxidation of the combustion chamber after a long period
of inactivity is not to be considered as a manufacturing fault.

- Any perceived noise during operation may be caused by the expansion settling of the plates that make up the boiler
unit. These noises are accentuated especially during ignition and switching off phases of the appliance and are not to
be considered a manufacturing fault.

- If ignition fails, empty the pellets out of the brazier; only then can you reignite the appliance in order to avoid

gasification and consequent “explosion” during ignition which could lead to the breakage of the door glass.

- The appliance works exclusively with wooden pellets; do not burn different fuels.

- The appliance can work only if connected to the heating system and with water inside the boiler unit. Do not start the

appliance for any reason if a plumbing connection in compliance with current regulations has not been done and if
you have not filled the entire boiler unit and system with water in order not to compromise its life.

- The noise heard during the ignition stage is due to the automatic cleaning of the turbulators.

- The noise level of the appliance is emphasised if the pellet container is empty. Therefore we recommend that you

always keep the pellet level to at least half tank.

- If there is soot and fine particulate in the room where the appliance is installed, check the seal on the flue gas pipes
and the filter of the ash vacuum device used for cleaning.

- In the event of overheating, the appliance will switch off when it reaches 85°C.

What happens if…

…the pellets do not ignite

If the ignition fails, the display will show the alarm message “NO IGNITION”.
Cancel the alarm and reset the appliance to standard condition by pressing button 4 for a few seconds.

DISPLAY VISUALISATION

ORIGIN OF ALARM

AL 1 - BLACK OUT
ACTIVE ALARM

Black-out alarm. When power is cut off under determined conditions (see“What happens if…”)

AL 2 - FLUE GAS PROBE
ACTIVE ALARM

Faulty or disconnected flue gas temperature sensor.

AL 3 - HOT TEMP
ACTIVE ALARM

Flue gas over-temperature. Before displaying the alarm, or when flue gas maximum temperature
is reached (Pr14). the display shows “HOT FLUE GAS”.

AL 4 - EXTRACTOR-FAILURE
ACTIVE ALARM

Faulty flue gas extractor. When the encoder (tachometer) in the extractor detects an extractor
speed equal to 0.

AL 5 - NO IGNITION
ACTIVE ALARM

No ignition. When the flue gas minimum temperature (Pr13) is not reached within the maximum
ignition cycle time (Pr01).

If ignition fails, empty the pellets out of the brazier; to avoid gasification, the appliance can only be re-ignited
after having emptied the un-burnt pellets.

...the fire door or the pellet container door is open or not properly closed

If the door is left open or not properly closed, the pellet loading will not start, therefore the appliance will not switch itself
on. If the door is opened during normal operation, the appliance switches to “THERMAL SAFETY” alarm.

...the flue pipe is dirty, blocked or not correctly installed

If the flue is dirty, blocked or incorrectly manufactured, pellet loading will not start, thus the appliance will not switch itself
on. If the flue is obstructed during normal operation, the appliance switches to “DEPRESS.-FAILURE” alarm.

...the appliance is overheated

If the water in the boiler body is overheated (>94°C), the pellet will not be loaded because the manual reset thermostat
cuts in. If this happens during normal operation, the appliance switches to “THERMAL SAFETY” alarm. It is therefore
necessary to reset the “manual reset thermostat” (see “Components of the appliance”) before switching the appliance on
again. To reset, it is necessary to remove the black cap and press the button below.

...lack of power (blackout)

If a power blackout occurs for a shorter time than Pr48, when power is restored, the appliance will immediately re-start in
the working mode (recovering the set working power).
If the outage lasts longer than Pr48, when power is restored, the appliance will enter the “STOP FIRE” (stand-by) mode
running the entire switch-off cycle until cooling. When this phase is over, the appliance can be restarted resuming work
at the set power.

Alarm signals

The following table describes the different alarms which may appear.

32

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

AL 6 - NO PELLET
ACTIVE ALARM

Sudden shut-down during the work phase. When, during the work phase, the flue gas
temperature drops below the minimum threshold (Pr28).

AL 7 - THERMAL-SAFETY
ACTIVE ALARM

Temperature safety device. When the safety thermostat (water over temperature) or one of the
micro switches (contact interrupted) fitted in the fire door or pellet container door cuts in. If the
safety thermostat cuts in the boiler stove must be manually rearmed.

AL 8 - DEPRESS.-FAILURE
ACTIVE ALARM

Poor depression. When the flue gas pressure switch cuts in (contact interrupted) due to poor
draught in the flue pipe.

AL 9 - WATER PROBE
ACTIVE ALARM

Faulty or disconnected water temperature probe.

AL c - SF TRIAC ERROR
ACTIVE ALARM

Screw feed TRIAC error. When the screw feed gear motor does not stop for at least 0.2 seconds
during the maximum work interval of 8.0 seconds. Before the alarm is activated a safety relay
cuts in and forcibly cuts off the power supply to the gear motor.

Every alarm causes the appliance to switch-off immediately. The alarm state is reached after the time set on Pr11 (set as

default at 60”) and it can be reset by pressing button 4 for a while.

CLEANING AND MAINTENANCE

Precautions before cleaning

Before carrying out any cleaning or maintenance operations, make sure that:

- the appliance is off and has cooled down completely;

- the ash is completely cold.

- the ash vacuum device used for cleaning is suitable and its filter is in good condition.

Before re-starting the appliance, re-install all previously removed components.

During cleaning operations, use the personal protection devices specified in Directive 89/391/EEC.
The frequency for cleaning depends on the type and quality of pellet burnt; therefore, the indicated times may change.

Any problem affecting the appliance caused by lack of cleaning will not be covered by the warranty. The failure
of these operations could affect the safety of the product.

Cleaning operations may be carried out by the end user, as indicated in the paragraph below.

Routine cleaning

The routine cleaning of the appliance must be done at least every 10 days of operation or after 20 ignition cycles, so as
to always guarantee efficient performance and optimal operation. Please proceed as follows:

33

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

Empty the ash drawer (Figure 1).

3 2 1

EN - Rev 1.1

Thoroughly clean the brazier from combustion residues by taking it out from its position and removing any residues

inside (Figure 2). Use a suitable ash vacuum device to remove any ash deposited under the brazier (Figure 3).

To remove any deposits, it is also recommended that you scrape the inner walls of the combustion chamber with a

spatula. Do not use tools that can reduce the thickness of the metal sheet of the boiler unit.

WARNING: use suitable ash vacuum devices equipped with a fine mesh filter in order to prevent ash from being

blown into the room and to prevent damaging the vacuum cleaner. We do not recommend the use of normal

vacuum cleaners.

Non-routine cleaning

The extraordinary cleaning of the appliance must be done at least every 90 days so as to always guarantee efficient
performance and optimal operation. Please proceed as follows:

Perform routine cleaning;

Remove the “extractor flue gas pass inspection front plate” by unscrewing the 4 screws (figure 4).

Using the ash vacuum, vacuum the deposit inside (figure 5).

Remove the front guard (figures 6 and 7).

35

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

10 9 8

After removing the turbulator inspection front plate (Figure 8), vacuum the deposits on the inside using a suitable ash

vacuum device (Figure 9). When finished, replace the plate and front guard.

To ensure correct operation, it is necessary to remove the sawdust deposited on the base of the tank (Figure 10) at least

once every 30 days. The pellet tank must be emptied at the end of every season.

Cleaning the ceramic glass

Always clean the glass when the appliance is off and has cooled down completely. Use a damp cloth or a detergent
specifically formulated for ceramic glass. Do not use abrasive sponges. Do not clean the glass if still warm; changes in
temperature can lead to breakage.

36

PELLET-BURNING BOILER ECOMPACT 150-190-250-290

EN - Rev 1.1

Cleaning the flue

The flue must be cleaned at least once a year, at the beginning of winter, and whenever it becomes necessary.
It is important to check for any obstructions in the flue before switching the appliance on following long periods of
inactivity.
If the flue is not cleaned, the operation of the appliance and its components may be compromised.

The cleaning frequency of the appliance and flue depends on the quality of the pellets used.

USE TOP QUALITY PELLETS TO OBTAIN THE BEST RESULTS.

Maintenance

Timely and systematic maintenance is essential for guaranteeing correct operation, optimal heat performance and
durability of the device. Therefore, qualified staff should check the appliance at least once a year at the beginning of the
season.

You must periodically check the seals because the latter guarantee the air- and water-tightness of the appliance and its
good functioning; if they are worn or damaged you need to be replace them immediately by contacting a Klover
Authorised technical assistance centre.

For proper operation, the appliance must undergo routine maintenance performed by a Klover Authorised
technical assistance centre at least once a year.

STANDARD WARRANTY CONDITIONS

1. General information

This standard warranty (“Klover Warranty”) is issued by Klover Srl, San Bonifacio, Via A. Volta no. 8, for the products

shown on the website www.klover.it (the “Products”). The Klover Warranty does not affect the rights provided for by
European directive 99/44/EC or by Italian legislative decree no. 206/2005 “Consumer Code”, where applicable.

The Klover Warranty is limited to Italy. Klover Srl invites Consumers not based in Italy to contact the dealer from which
they bought the Product, to obtain the current warranty conditions.

2. Activation of Warranty

The Klover Warranty must be activated, within 60 days from the date of purchase, on the website www.klover.it in the
section “Register your warranty”. The requested details should be completed, and a delivery note or other fiscal proof of
purchase (e.g. receipt) should be attached).

Alternatively, the warranty certificate, which can be found in each Product pack (the “Warranty Certificate”) must be sent

to Klover Srl, within the same period of 60 days from the date of purchase, by following the instructions on the certificate.
When registering or sending the guarantee, please ensure that the customer copy of the Warranty Certificate is retained.
It must be duly completed and signed by the Consumer and by the installer, together with the delivery note or other form
of proof of purchase, in order for the Klover Warranty to be valid.

3. Two-year Klover Warranty

The Klover Warranty covers the free repair of the Product all parts of the Product that are found to be defective at origin,
due to defects confirmed by Klover Srl to be exclusively attributable to the manufacturer. If it is not possible to repair the
Product in any way, it will be replaced. In both cases, there will be no change to the expiry or terms of the warranty provided
when the Product was purchased.
The Klover Warranty offers all the advantages of a service guaranteed directly by Klover Srl through its network of

authorised service centres (Centri di Assistenza Tecnica or “C.A.T.”) in Italy. The list can be found on the website

www.klover.it.

The Klover Warranty will remain in effect for a period of 2 years from the date of purchase, if proven by a delivery note or
other proof of purchase (e.g. receipt), stating the name of the seller, the product that was bought, and the date of purchase.

Product components replaced by an authorised dealer at the Consumer’s expense as they were “out of warranty” after

expiry of the two-year period will be guaranteed by Klover Srl for one year from the date of replacement, excluding costs
of intervention, labour and ancillary costs.

4. Five-year Klover Warranty

If the First Switch-on service is provided by an authorised dealer, within 3 months from the date of purchase, the Consumer
will be entitled to the Warranty on the main boiler unit for a period of 5 years from the date of purchase.
The cost of the First Switch-on service is paid by the Consumer.
This Klover Warranty is valid on condition that the seasonal maintenance is performed by the local service centre as
indicated in the user manual (for example, Safe Top boiler units require annual use of the Long Life protection).
The First Switch-on Report, duly completed and signed, must be kept carefully to ensure that the Klover Warranty remains
operational.

5. Complaints and Assistance

As provided for by Legislative Decree 24/2002, complaints should be sent to the retailer through whom the Product was
bought.
Once the retailer has checked that the Klover Warranty is in force and has not been invalidated, they will contact the local
service centre to agree the terms of intervention to verify and eliminate the reported fault. If the Consumer contacts the
service centre directly, the service centre must immediately inform the retailer from whom the Product was bought.
If, while inspecting the Product, the service centre finds that the reported defect is not one of the defects covered by the
Warranty, the call-out and any works completed, will be paid by the Consumer.
In order to improve the service and reduce intervention time, Consumers are asked to provide the details of the Product

they are calling about. In particular, the following information should be provided: • Warranty Certificate number • the name,
model and serial number of the Product • the date of purchase • the reported defect.

Klover Srl will not be liable for any delays in carrying out repairs or replacements of the Product.
