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:

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.

DIVA SLIM PELLET BOILER STOVE

EN - Rev. 1.0

REAR VIEW

SIDE WALL

SIDE WALL

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 back of the
appliance, 800 mm from the front and 750 mm from the upper part.

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
(e.g. garages).

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 75 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.

11

DIVA SLIM PELLET BOILER STOVE

EN - Rev. 1.0

Fig. A

20

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.

The flue and connection to the same

The flue is an essential element for the efficient operation of the appliance. The flue must have a minimum cross­sectional area as that indicated in the technical specifications of the appliance (100 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 have a length greater 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 forming condensation;

- Parts made from non-combustible materials (it is absolutely prohibited the use of aluminium flue) - capable of

withstanding combustion gases and potential condensation - must be used for mounting the flue gas pipes (for the
section from the appliance to the flue inlet);

- It is forbidden to use fibre cement pipes to connect the appliance to the flue;

- Flue gas conduits must not pass through rooms in which the installation of combustion devices is prohibited;

- The flue gas conduits must be assembled in such a way as to guarantee adequate sealing of flue gases during low

pressure operation of the appliance;

- The installation of horizontal sections is prohibited;

- It is prohibited 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;

12

EN - Rev. 1.0

INSPECTION HOLE

INSPECTION HOLE

MINIMUM 0.5 M

- It is forbidden to allow other air intake conduits 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 depression and the flue pipe in 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 current regulations) and

equipped with seal gaskets with a minimum diameter of 100 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 tubes must be smoketight

thanks to special seals capable of withstanding temperatures of up to 250°C. Attach the pipes to the wall with special
collars to prevent any vibration.

- IT IS STRICTLY FORBIDDEN TO INSTALL DRAUGHT REGULATION VALVES (BUTTERFLY VALVES). WALL

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.

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 no less 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 so­called 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 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:

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

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.

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”.

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-condensate mixing valve between the delivery and
return pipes on the appliance’s heating system. The anti-condensate 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.

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 stove connected to a heating system and (potentially) an external plate heat
exchanger for the production of DHW.

DHW

cylinder

Plumbing layout 1 involves connecting the boiler stove 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 left technical compartment.
DHW generation, where required, will be obtained through a plate heat exchanger fitted outside of the boiler stove and
controlled by a flow switch, which is also connected to a terminal on the boiler stove. This function of this switch is to
bring the appliance immediately to the DHW output working mode and to switch a three-way motor-driven valve to give it
priority.

PLUMBING LAYOUT “2” – Not used

PLUMBING LAYOUT “3” – Boiler stove connected to a heating system and a DHW cylinder.

23

DIVA SLIM PELLET BOILER STOVE

EN - Rev. 1.0

Puffer

Centralised

puffer

Plumbing layout 3 involves connecting the boiler stove to a heating system managed by one or more room thermostats.
These are connected to the terminal located inside the appliance’s left technical compartment. DHW will be generated by
means of a hot water cylinder fitted outside of the boiler and controlled by a temperature probe connected to the
appliance.
The three-way motor-driven valve, controlled by the pellet boiler stove, will manage heating of the system or hot water
cylinder, giving priority to the latter.
Setting “Menu 01 – Select season” to SUMMER allows for controlling the hot water cylinder only during summer (thus
with the heating system off).

PLUMBING LAYOUT “4” – Boiler stove connected to a centralised puffer controlled by an H2O probe connected to the
boiler stove.

Plumbing layout 4 involves connecting the boiler to a centralised puffer controlled by a temperature probe connected to
the appliance. The boiler stove will therefore operate only at the set temperature of the centralised puffer (“SET
PUFFER” can be set using buttons 1 and 2). In this type of system there are no room thermostats or three-way valves
connected to the pellet boiler stove.

Initial filling of the system

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.

24

DIVA SLIM PELLET BOILER STOVE

EN - Rev. 1.0

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 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 few seconds, “START” will
appear on the display and the flue gas extractor, ignition plug and motor for the automatic cleaning of the flue gas path
will all switch on. After a few seconds, the appliance enters a pre-load phase “PELLET P-LOAD” during which a
continuous supply of pellets is loaded. After the pre-loading phase the appliance switches to the “HOLD FLAME” phase
where the pellets are loaded into the brazier at regular intervals. When the flame is lit, the display shows the message
“FIRE ON”. 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 IGNIT ALARM”. 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 - HOLD FLAME = Loading pellets (intermittent load) and plug operating.
Step 5 - FIRE ON = 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”.

PROBLEMS, ALARMS, USEFUL TIPS

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 properly

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 IGNIT ALARM”.
Cancel the alarm and reset the appliance to standard condition by pressing button 4 for a few seconds.

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.

supply to the gear motor.

Alarm signals

The following table describes the different alarms which may appear.

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 5 days of operation or after 20 ignition cycles, so as to
always guarantee efficient performance and optimal operation. Please proceed as follows:

29

DIVA SLIM PELLET BOILER STOVE

EN - Rev. 1.0

3 1 2

Empty the ash drawer (Figure 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 “flue gas path side (right-hand side) inspection plate” by loosening the 2 screws (Figure 4) and suck up any

ash deposits inside it (Figure 5).

After opening the “lower inspection compartment”, remove the “flue gas path front inspection plate” (Figures 6 and 7).

Remove the deposits inside it using a suitable ash vacuum device (Figure 8). After completing this operation, put the

“flue gas path front inspection plate” back into place and check its airtightness.

12 9 10

To ensure correct operation, it is necessary to remove the sawdust deposited on the base of the tank (Figure 9) at least

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

Annual cleaning

The annual cleaning of the appliance must be done at least once a year so as to always guarantee efficient performance
and optimal operation. To complete these operations, we recommend contacting the Authorised Technical
Assistance Centre, which will proceed as explained below:

Perform routine and extraordinary cleaning;

Remove the upper grille (Figure 10).

Pull the probe out of the upper cover (Figure 11) and unscrew the eight hex head screws to remove the latter (Figure 12).

DIVA SLIM PELLET BOILER STOVE

EN - Rev. 1.0

18

Vacuum the ash residues inside combustion chamber of the flue gas path (Figure 18).

After completing this operation, put the previously removed components back in place.

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.

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.
