DIVA PELLET BOILER STOVE
EN - Rev. 2.2
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:
Indication of the standard,
base reference for the quality
classes ENplus
Indication of the quality
class of the certified pellet
(preferable A1)
IT xxx
Code of the certified company
consisting of two elements:
- Symbol of the country of
production (example “IT”)
- Progressive number assigned at
the acquisition of the
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.
9
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
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.
Relocating the appliance should not be done by forcing on the handle, glass or ceramics.
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.
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.
REAR WALL
50 cm
50 cm
SIDE WALL
SIDE WALL
15 cm
Any shelves or false ceilings mounted above the appliance must be at least 100 cm away from the top part of it.
Furniture and movable objects must be positioned at least 15 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, where it is necessary to disconnect the
device from the system, will not be recognised under warranty as described in chapter “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 grid).
If the wall behind the appliance is on the outside, we recommend you make the hole near it at about 20 cm above the
ground (see example in Fig. A).
If it is not possible to put an air vent in the wall behind the appliance, make a hole in a perimeter wall in the room where it
is installed. 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.
10
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
Do not connect the external air vent directly to the appliance through piping. 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.
Fig. A
20
The flue pipe and connection to the same
The flue pipe 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 chimney stack flue outlet surface must be twice as big as the flue pipe 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 subhorizontal 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;
- If the flue pipe is installed on the outside it is essential that it is insulated in order to avoid the flue gas cooling
allowing condensation to form;
- Parts made from non-combustible materials (it is absolutely prohibited the use of aluminium flue pipe) - 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 pipes must not pass through rooms in which the installation of combustion devices is prohibited;
- The flue pipes 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;
11
DIVA PELLET BOILER STOVE
-
EN - Rev. 2.2
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 1.5 MT 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 air tight
through special seals which resist up to 250° C. Attach the pipes to the wall with special collars to avoid any
vibration.
- IT IS STRICTLY FORBIDDEN TO INSTALL DRAUGHT REGULATION VALVES (BUTTERFLY VALVES).

If the flue should be old or too big (internal diameter greater than 15 cm), duct the flue using a stainless steel pipe,
properly 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, including the initial T-shaped
fitting.
12
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
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;
- In must be shaped in such a way as to prevent rainwater or snow from seeping into 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 220V – 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.
13
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
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 rear 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 prepared on the back of the appliance (blue and brown wires) will have an output voltage of 220 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).
14
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
Connection to the room thermostat
On the back of the appliance there is a bridged terminal which is used to connect the environment thermostat that will
command the operation.
OPERATING PRINCIPLE
Open contact:
- The appliance switches directly to economy mode operation “T-OFF 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 (30 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.
- The temperature falls below the temperature differential set on Pr43 (set as
default at 5°C), in other words H2O Temperature < (“SET H2O” – Pr43).
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 threshold set on Pr50 (set as default at 83°C), the circulating pump of the
system is forcedly switched-on to ensure the disposal of excessive heat, thus avoiding the reaching of high temperatures
of the water in the boiler. For this reason it is recommended that the heating system is not entirely closed.
WARNING: If the room sensor in the “Remote Control” is also enabled (see “Menu 04 – Enable Contact”) the appliance
enters the economy mode when both instances are satisfied.
HYDRAULIC CONNECTION
The plumbing connections must be made in a rational way using the connections on the template of the appliance. To
facilitate the connection of the pipes, all the plumbing connections have been fitted on the rear side, leaving space to
make the appropriate connections.
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.
N.B.: 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 goes 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.
The maximum mains water pressure should never exceed 3 bar; recommended operating pressure: 1.5 bar
(during operation).

For example:
In this condition...
…to control the appliance with only the KLOVER “Remote control” room temperature sensor:
- enable the room sensor on the “Remote control” (Stove settings menu +> Enable room sensor -> ON)
- disable the boiler thermostat contact on the display of the appliance (Menu 4 - Enable contact -> OFF)
In this case, the appliance first enters economy mode operation, and then automatically switches off when the desired
room temperature (detected with KLOVER “Remote control”) is reached.
...to control the appliance with both the KLOVER “Remote control” room temperature and the boiler thermostat:
- enable the room sensor on the “Remote control” (Stove settings menu +> Enable room sensor -> ON)
- enable the boiler thermostat contact on the display of the appliance (Menu 4 - Enable contact -> ON)
In this case, the appliance first enters economy mode operation, and then automatically switches off when both
temperatures have been reached.
...to control the appliance with the boiler temperature only:
- disable the room sensor on the “Remote control” (Stove settings menu +> Enable room sensor -> OFF). The room
sensor is automatically disabled if no external “Remote control” is connected.
- enable or disable the boiler thermostat contact on the display of the appliance (Menu 4 - Enable contact -> ON/OFF).
In this case, the appliance first enters economy mode operation, and then automatically switches off when the boiler
temperature (measured with an external thermostat immersed in the boiler) has been reached. This may be a viable
solution to heat DHW in summer.
...to control the appliance without using external thermostats, but only with the water temperature in the heating system:
- disable the room sensor on the “Remote control” (Stove settings menu +> Enable room sensor -> OFF). The room
sensor is automatically disabled if no external “Remote control” is connected.
- enable or disable the boiler thermostat contact on the display of the appliance (Menu 4 - Enable contact -> ON/OFF).
The contact must obviously be bridged (already provided as standard).
Only when reaching the temperature set in “SET H2O” the appliance enters economy mode operation.

INITIAL START-UP
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 “manual 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 “manual 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.
22
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
The system and the water inside the boiler can be emptied by opening the “boiler body and system drain cock” situated
at the back 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 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 rear side 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 07 – 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.
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 resistance switch on. After a few seconds the appliance goes into
a phase of preheating “AFTERPRE PRE-HEAT” useful to sufficiently heat the ignition resistance before the loading of
the pellets in the brazier. 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”. 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 25/30 minutes max. and is divided into five steps:
Step 1 - START
= Ignition of the flue gas extractor.
Step 2 - AFTERPRE PRE-HEAT = Waiting for the resistance preheating.
Step 3 - PELLET P-LOAD
= Pellet pre-load (initial continuous load) and resistance ignition. (Not as standard
settings)
Step 4 - HOLD FLAME
= Loading pellets (intermittent load) and resistance operating.
Step 5 - FIRE
= Resistance 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.
23
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
Working mode
During the working phase, by pressing 1, you can set the “SET H2O” (maximum water temperature in the boiler). When
this temperature is reached, the appliance enters economy mode operation “T-H2O ECONOMY”.
5°C before reaching the temperature set on “SET H2O”, the appliance starts modulating output by decreasing the pellet
intake and reducing the flue gas extraction speed.
For example:
-
“SET H2O” set at 75 °C
Working power set at 5
Working power automatically changes to 4 when the temperature reaches 71°C.
Working power automatically changes to 3 when the temperature reaches 72°C.
Working power automatically changes to 2 when the temperature reaches 73°C.
Working power automatically changes to 1 when the temperature reaches 74°C.
Working power automatically changes to economy mode operation “T-H2O ECONOMY” when the temperature
reaches 75°C.
The appliance will now automatically switch itself off 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 (30 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 automatically starts up again if the following condition occurs:
- The temperature falls below the temperature differential set on Pr43 (5°C as default setting) or
H2O Temperature < ( “SET H2O” – Pr43 ).
If the above condition occurs when the switch-off cycle is not yet completed, please wait until the cycle is complete.
The cleaning cycle of the brazier (displayed under “BRAZIER CLEANING” is done at predetermined time intervals for an
established period (see “PCB parameters”).
Switch-off cycle
Pressing button 4 (ON/OFF) the appliance switches itself off. The display will show “FINAL CLEANING”. Pellet loading is
stopped, turning off the gear motor. The flue gas extractor speed increases to maximum and then switches off after the
cooling of the appliance, displaying "OFF”.

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 body 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
body. 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 door of the appliance does not provide airtight closing (opening for secondary-post combustion air passage); any
perceived smoke smell (especially during ignition) is not to be considered a manufacturing fault.
- 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 body. Do not start-up
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 body and system with water in order not to compromise its duration.
- 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 you find soot and fine particles in the room where the appliance is installed, check the sealing of flue pipes and the
filter of the ash vacuum device used for cleaning.
What happens if…
…the pellets do not ignite
If the ignition fails, the display will show the alarm message “NO IGNIT ALLARM”.
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; 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 fire 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).
26
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
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.

ORIGIN OF ALARM
Black-out alarm. When power is cut off under determined conditions (see“What
happens if…”)
Faulty or disconnected flue gas temperature sensor.
Flue gas over-temperature. When flue gas temperature is higher than 260°C.
Before displaying the alarm, or when flue gas maximum temperature is
reached (Pr14). the display shows “HOT FLUE GAS”.
Faulty flue gas extractor. When the encoder (tachometer) in the extractor
detects an extractor speed equal to 0.
No ignition. When the flue gas minimum temperature (Pr13) is not reached
within the maximum ignition cycle time (Pr01).
Sudden shut-down during the work phase. When, during the work phase, the
flue gas temperature drops below the minimum threshold (Pr13).
Temperature safety device. When the safety thermostat (water over
temperature) or fire door micro switch (contact interrupted) cuts in. If the safety
thermostat cuts in the boiler stove must be manually rearmed.
Poor depression. When the flue gas pressure switch cuts in (contact
interrupted) due to poor draught in the flue pipe.
Faulty or disconnected water temperature probe.
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 30”) 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 required cleaning frequency depends on the type and quality of the pellets used. The schedule indicated below may
therefore vary.
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.
Routine cleaning
The ordinary cleaning of the appliance must be done at least every 20 hours of operation or after 3-4 ignition cycles, so
as to always guarantee efficient performance and optimal operation. Please proceed as follows:
1
Empty the ash drawer (Figure 1).
28
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
3
2
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).
4
Press repeatedly (from bottom to top and vice versa for the entire length of the rod) the two side scrapers to allow
cleaning of the side flue gas pass (Figure 4).
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 15 days so as to always guarantee efficient
performance and optimal operation. Please proceed as follows:
Perform routine cleaning;
29
DIVA PELLET BOILER STOVE

Clean the pipes inside the combustion chamber using the supplied brush and passing it repeatedly between one and the
other pipe (Figure 5).
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 body.
6
7
Do not force the flue gas extractor flaps with the ash
vacuum device hose.
After removing the ash drawer pull out the bottom under it (Figure 6) and vacuum the deposits on the inside using a
suitable ash vacuum device (Figure 7). When finished, replace the bottom and the ash drawer.

After unscrewing the hand-wheels, extract the side flue gas pass inspection vent (Figure 9). Remove the deposits inside
using a suitable ash vacuum device (Figure 10). When finished, close the pipes making sure that you have secured the
two inspection openings. Replace the front panel below.
31
DIVA PELLET BOILER STOVE
EN - Rev. 2.2
11
To ensure correct operation, it is necessary to remove the sawdust deposited on the base of the tank (Figure 11) at least
once every 15 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.
Cleaning the flue pipe
The flue pipe cleaning must be performed at least once a year, at the beginning of winter, and anyway whenever
necessary.
It is important to check for any obstructions in the flue before switching the appliance on following long periods of
inactivity.
If cleaning of the flue pipe is not performed, the operation of the appliance and its components may be jeopardised.
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.

KLOVER s.r.l. guarantees the quality of materials, good construction and functionality of the product for a
period of 2 years, under the following conditions:
1. On its own unquestionable judgement, the device evidencing material or construction faults will be repaired or
replaced; with the exception of all costs relating to transport, restoration (hydraulic disassembly and assembly
operations, any masonry works and any other necessary intervention) and accessory materials.
2. The warranty does not cover:
- the ceramic glass and ceramic-majolica and/or varnished steel linings, as they are very fragile and can get
accidentally damaged;
- any part made of ceramic-majolica evidencing altered colour shades, pitting, cracks, shading and slight
dimensional variations, as these cannot be regarded as product defects but features deriving from the
handmade processing techniques used;
- the cast iron brazier, the cast iron grid and plate, smoke deflector or flame arresters, gaskets, fuses or batteries
inside the device's electronic system and any other removable component, where it is not proved that their
condition is due to a manufacturing defect rather than the effects of wear;
- electric and electronic parts, in which the malfunction can be traced to a non-compliant electrical connection,
natural disaster (lightning, electrical discharges, etc.) and variation in voltage other than the nominal voltage;
- any parameter calibration intervention due to the type of fuel or installation of the device.
3. The replaced components are guaranteed for the remaining period of the warranty, starting from the date of
purchase and/or for a period not exceeding 6 months.
4. The use of poor-quality wood pellets or other fuel could damage the components of the device thereby voiding the
relevant warranty and the manufacturer's liability. Therefore, we recommend using the fuel type indicated in our
specifications;
5. Incorrect installation carried out by unqualified personnel, tampering with, failure to comply with the instructions
contained in this "use and maintenance manual" and those regarding “workmanlike installation” shall void any
warranty rights; the same applies to damages deriving from external factors. At all events, any compensation for
direct or indirect damages is excluded, regardless of the nature and cause of the damages.
6. Please bear in mind that the goods travel under the customer’s responsibility, even if delivered carriage free,
therefore we shall not be held liable for any damages due to loading and unloading operations, accidental knocks,
storage in unsuitable places, etc.
7. The boiler unit of water-based products only connected to a heating and/or sanitary water system is guaranteed for 5
years, at the above-mentioned conditions.
8. The warranty is to be considered valid only if the initial start-up report and warranty start is duly completed in all its
parts by the Authorised Technical Assistance Centre at the first ignition. For the validity of the warranty, the first
ignition must only be carried out by the Authorized Technical Assistance Centre within 3 months from the
date of purchase and no later than 30 days from date of installation;
For any disputes the Courts in Verona have sole jurisdiction.
