Smoke Control Areas
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels
or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with Ministers in
the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981,
applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have
been "authorised" in Regulations and that appliances used to burn solid fuel in those areas (other than "authorised"
fuels) have been exempted by an Order made and signed by the Secretary of State or Minister in the devolved
administrations.
PELLET FIREPLACE 22
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of
smoke control areas and you can contact them for details of Clean Air Act requirements”
Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke
control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if located
in a designated smoke control area. It is also an offence to acquire an "unauthorised fuel" for use within a smoke control
area unless it is used in an "exempt" appliance ("exempted" from the controls which generally apply in the smoke control
area).
“The Klover Pellet Fire Place (model - PFP22, PFP22-B) has been recommended as suitable for use in smoke
control areas when burning wood pellets.”

Pellet properties
The stove 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 10 %
 100% wood. Totally additive-free.
 Maximum ash residue - 1.1 %
For good fireplace performance, 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 EN 14961-2 Wood pellet class A1-A2 (maximum moisture
level of 10%), 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 fireplace.
International Standards must be respected for the manufacturing of pellets as in France, Austria, Germany and recently in some Eastern countries, also
complying with the DIN 51731 and the O-NORM M7135 Standards in the production phase. These Standards establish the minimum values in order to
check pellet quality. In Italy there is no official Standard, but we recommended the use of pellets that comply with the above Standards.
The use of poor quality pellets or any other material can damage the fireplace boiler's operation, voiding the warranty and exempting the
manufacturer from all responsibility.
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 the best installation of the fireplace heating system is to determine its optimal location; regarding this the following data needs to be
taken into account:





The possibility of creating an external air vent;
Possibility of creating a straight flue and possibly coaxial at the fireplace heating system outlet;
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 fireplace, 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.
installation of a load distribution plate) must be taken.
Once the best location for the appliance is determined, it is possible to position the fireplace heating system following the indications below.
IF THE FIREPLACE INSERT IS TO BE INSTALLED IN A CONVENTIONAL FIREPLACE, PROCEED AS FOLLOWS:
1.




make sure the floor has the specifications given below:
it must be able to support the weight of the fireplace and its accessories.
It must be strong enough to permit anchoring with anchor plugs in complete safety. If it is not, make a new metal mesh reinforced concrete slab over
the existing (cleaned) fireplace floor.
It must be perfectly flat.
The walls must be as perpendicular as possible to the floor.
2.
Make sure the space is large enough to house the fireplace insert.
After checking the above, install the unit as follows:
3.
Fit the fireplace insert and base into the space and , once definitively positioned, drill the holes for the base anchor bolts.
4.
Use expansion bolts to anchor the base to the floor. Take care when doing so that the structure does not tip over when the insert itself is
extracted.
5. Make the plumbing, electrical and flue connections as required by law.
N.B.: during the electrical and plumbing hook up, MAKE SURE that the hoses and electrical cable are long enough to allow the insert's guides to
extend outwards from the fireplace itself.
IF THE FIREPLACE INSERT IS TO BE INSTALLED FROM NEW, PROCEED AS FOLLOWS:
1.



make sure the floor of its frame has the specifications given below:
it must be able to support the weight of the fireplace and its accessories.
It must be strong enough to permit anchoring with anchor plugs in complete safety. If it is not, make a new metal mesh reinforced concrete slab.
It must be perfectly flat.
2.
Place the supporting frame on the wall and anchor it with the expansion bolts.
Take care when doing so that the structure does not tip over when the insert itself is extracted.
3.
Make the plumbing, electrical and flue connections as required by law.
N.B.: during the electrical and plumbing hook up, MAKE SURE that the hoses and electrical cable are long enough to allow the insert's
guides to extend outwards from the fireplace itself.
4.
Now install the external covering.
Do not cover the fireplace for at least 6-7 days, in order to verify the tightness of all plumbing connections.
6
Spaces around and above the stove
The following figure shows the minimum clearances to be observed in installing the fireplace insert in relation to the walls or two "shoulders" of the covering
(if the latter are not easily removable).
4 cm
9 cm
9 cm
The space between the insert's walls and those of the fireplace itself must be closed with a compensating surround which is easy to remove for
maintenance.
When servicing the unit, we recommend inspecting its sides and rear.
External air vent
During operation, the stove 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 combustion air is drawn into the fireplace insert by a dia. 50mm pipe at its back
If the wall behind the fireplace is an outer wall, make a 15 cm diameter hole 10 cm from the base of the fireplace insert (see Fig. 1).
The hole must be protected externally with a fixed grille. Periodically check that the grille is not obstructed by leaves or other material, as this may
block the passage of air.
If it is not possible to include an air vent in the wall behind the stove, make a hole in a perimeter wall in the room where the stove is installed (fig. 2).
If it not possible to realise the external air vent in the same room where the fireplace heating system 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).
7
Protect all structures that can catch fire against the radiated heat of the fire.
The UNI 10683 Standard FORBIDS the drawing of combustion air from garages, warehouses storing combustible materials, or from business
premises with a fire hazard.
Do not connect the external air vent to the stove 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 fireplace heating system must be installed.
Extractor fans can cause operating problems to the stove when they are installed in the same room or space as the device.
The flue pipe and connecting the same - Chimney stack
The Flue is a fundamental component for correct functioning of the fireplace heating system. The minimum section of the flue must be that indicated in the
fireplace heating system technical features (120 mm). Each fireplace must be equipped with its own flue, without other adjoining elements (boilers, chimneys,
stoves etc.). Flue dimensions are closely related to its height, which must be measured from the fireplace heating system flue gas outlet to the chimney base.
In order to guarantee 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 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;
 If the flue is installed outdoors or in a cold room (e.g. boiler room) it is absolutely necessary that it is insulated to prevent cooling of the
fumes and the formation of condensate;
 Parts made from non-combustible materials - 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;
 Installation of horizontal sections should be banned;
 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;
 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.
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 so-called reflux zone, in order to
prevent the formation of counter-pressures preventing the free discharge of combustion by-products into the atmosphere.
8
It is therefore necessary that the minimum heights - indicated in the following diagrams - are observed:
FURTHER SPECIFICATIONS TO BE CONSIDERED
The stove functions with the combustion chamber in depression; it is fundamental that the discharge be hermetically sealed.
We recommend using rigid stainless steel pipes having a minimum diameter of 120 mm, with sealing gaskets.
The pipes must have a double wall or be suitably insulated with rock wool. The maximum temperature of the pipe must not exceed 70 °C.
IT IS MANDATORY TO HAVE AN INITIAL VERTICAL SECTION OF AT LEAST 1.5 METRES IN ORDER TO GUARANTEE CORRECT FLUE GAS
DISCHARGE.
Every direction change must be carried out with a T-shaped fitting and inspection cap.
The pipes must be sealed against flue gas via suitable gaskets capable of resisting temperatures of up to 250 °C.
Secure the pipes to the wall using suitable metal collars in order to prevent any vibrations.
WARNING: IT IS STRICTLY FORBIDDEN TO INSTALL DRAUGHT REGULATION VALVES (BUTTERFLY VALVES).
If a “traditional” flue is used for discharging flue gas, make sure that it is in good working order and that it complies with the applicable standards. If the flue
should be too big (internal diameter greater than 14 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. The maximum permitted length
of the horizontal section is 2 metres. There must be a vertical section of at least 1.5 metres before any horizontal sections.
9
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.
KLOVER srl declines all responsibility for injury to persons and animals or damage to objects due to failure to connect the stove to earth or to
comply with IEC specifications.
The electronic control unit manages and controls all the device's functions, and ensures optimal operation at all times.
Control of any coupled boiler
If the pellet fireplace is to be coupled with a previously installed boiler in the system (e.g. wall-hung gas boiler), it must be ensured that the standard boiler
stops when the pellet-fired boiler stove takes over doing the heating. This is to make sure that you do not have to add up the heat output of the two
appliances installed on the system. This is why our set-up intervenes on the coupled boiler when the pellet fireplace heating pump starts. In this way, there
will never be two boilers functioning 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 fireplace insert (blue and brown wires) will have an output voltage of 220 V when the its pump is
working, and no voltage when the pump is at a standstill.
It is therefore easy to connect the 2 wires to a relay that will control the Room Thermostat input of the coupled boiler.
Control of a possible three-way motorized valve for the DHW system
The fireplace insert is equipped as standard with a control for a possible 3-way motorized valve to be installed on the domestic water circuit. A 4-wire cable
with protected faston connectors issues from the rear part of the appliance, which can be used to control this valve. The four wires in the cable have different
colours, and precisely:

the valve is at rest, the water passes from the gas boiler. Only when the fireplace temperature is sufficient (the value is set on the control panel) is the 3-way
valve powered, and so closes the gas boiler circuit and opens the pellet fireplace circuit.
N.B.: The brown wire can be used to control a service relay.
10
Connection to the room thermostat
A jumpered terminal clamp (voltage free contact) is installed on the rear of the boiler stove for connection to a room thermostat. In this way, connecting an
external thermostat with the function to open or close the contact depending on the heat demand will be easier.
OPERATING PRINCIPLE
Open contact:
1. The appliance switches directly to economy mode operation “T-OFF ECONOMY” thus minimizing its operating
power.
2. The pump switches off.
3. The temperature in the central heating cooker increases due to thermal inertia until it reaches the temperature
set with “SET H2O” and displays “T-H2O ECONOMY” on its monitor.
4. At this point, the fireplace will switch off automatically if at least one of the following conditions obtains:

it remains in economy mode operation “T-H2O ECONOMY” for a time set on Pr44 (30 minute default setting).

the temperature differential set on Pr43 (factory set value 5°C) or H2O Temperature > (“SET H2O” + Pr43) is
exceeded.
N.B.: the pump is calibrated to start whenever the temperature is ≥ 83°C (see table of parameters) to prevent
overheating.
WARNING: If the second room sensor on the remote control is enabled, to enable operation of the ROOM
TEMPERATURE CONTACT you must select “Menu 04” – Enable R.T. Contact = ON”; the fireplace will now enter
economy mode only if both of the following conditions obtain:
 Room temperature > “ROOM SET POINT”
 Room thermostat contact OPEN.
The fireplace will switch on again automatically if both the following conditions occur:

The contact of the room thermostat closes.

The temperature falls below the temperature differential set on Pr43 (5°C default setting) or H2O Temperature < ( “SET H2O” – Pr43 ).
If the above condition occurs when the boiler stove is still completing the switch-off cycle, please wait until the cycle is complete.
PLUMBING CONNECTION
The plumbing connections must be made in a rational way using the connections on the fireplace's template. To facilitate the connection of the pipes, we
have provided all plumbing connections on the rear left side, leaving space to make the appropriate connections.
The fireplace 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 shutoff valves based on the system and intended use.
N.B.: The fireplace 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.
The stove can only be installed in a room housing another boiler provided that the latter is a sealed-chamber device.
THE FIREPLACE HEATING SYSTEM MUST BE INSTALLED EXCLUSIVELY BY QUALIFIED STAFF. STRICTLY COMPLY WITH THE INSTRUCTIONS
GIVEN IN THIS GUIDE; IN THE EVENT OF ANY DOUBT CONTACT THE TECHNICAL ASSISTANCE CENTRE.
THE MANUFACTURER DECLINES ANY RESPONSIBILITY FOR DAMAGES CAUSED BY INCORRECT ASSEMBLY.
THE MAXIMUM MAINS WATER PRESSURE SHOULD NEVER EXCEED 3 BAR; RECOMMENDED OPERATING PRESSURE: 1.2 BAR.
DO NOT PASS ELECTRIC CABLES IN THE IMMEDIATE VICINITY OF THE FLUE GAS PIPE, UNLESS THEY ARE INSULATED WITH APPROPRIATE
MATERIALS
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.
CLEANING AND MAINTENANCE
Precautions before cleaning
Before carrying out any cleaning or maintenance operations, make sure that:
 The fireplace is off and has cooled down completely;
 The ash is completely cold;
 Before re-starting the fireplace, re-install all previously removed components.
For cleaning operations, personal protective equipment should be worn.i.e. gloves, goggles and dust masks, as directed in eu 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 fireplace caused by lack of cleaning will not be covered by the warranty.
Routine cleaning
The fireplace requires regular cleaning at least every 20 hours of operation or after 3-4 ignitions (depending on the type of pellets), so as to always
guarantee efficient performance and optimal operation.
Proceed as follows:
11
Carefully clean any ash out of the brazier by removing it form its housing. Use a vacuum cleaner to remove the ash deposited under the brazier.
Empty the ash drawer.
WARNING: use suitable “bin” type vacuum cleaners equipped with a fine mesh filter in order to prevent ash from being blown into the room and to prevent
damaging the vacuum cleaner.
Non-routine cleaning
To be performed at least once every 15 days.
Perform routine cleaning;
After removing the ash drawer, remove the two smoke diverters at the sides and carefully clean the combustion chamber.
12
After having removed the ash drawer, extract the underlying base. Clean both sides of the fumes passages with the swab.
Use a suitable ash vacuum cleaner to remove the internal residues then re-position the base and ash drawer.
Monthly cleaning
To be done at least once a month.
Do the routine and extraordinary cleaning;
Undo the front lock and extract the insert.
Remove the RH rear fumes turn plate and clean it with the swab.
13
Use a suitable vacuum cleaner to remove the internal residue then re-position the RH plate. Vacuum the deposit inside the fumes pipe connection, then
restore the insert to its original position.
For proper operation, you must vacuum the sawdust deposit from the guides and the base of the tank.
It is best to remove the front drawer from the guides, to facilitate efficient cleaning of the guides themselves.
The pellet tank must be emptied at the end of every season.
Cleaning the ceramic glass
Always clean the glass when the insert is off and completely cold. Use a damp cloth or a detergent specifically formulated for ceramic glass. Do not use
abrasive sponges.
Cleaning the flue pipe
This operation must be performed at least twice a year, at the beginning and half-way through the winter season, and whenever it becomes necessary.
It is important to check for any obstructions in the flue before switching the insert on following long periods of disuse.
If it is not cleaned, the functioning of the fireplace heating system and its components may be jeopardised.
The cleaning frequency of the fireplace 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 to the correct operation, optimal heat performance and durability of the device. Therefore, qualified staff
should check the stove at least once a year at the beginning of the season.
It is advisable to stipulate an annual contract for product maintenance with the Authorised Technical Assistance Centre (TAC).

Menu 04 – Enable R.T. contact (only available if the remote control room thermostat sensor is enabled)
Enables operation of the room thermostat contact if the room temperature sensor on the remote control is enabled (see the “Remote Control” manual).
The Room Thermostat contact operation is always active if the room sensor on the external remote is disabled.
For example:
In this condition...
…to control the boiler with only the KLOVER remote control ambient temperature sensor:

enable the room sensor on the remote control (stove settings menu +> Enable room sensor -> ON)

disable the boiler thermostat contact on the fireplace display (menu 4 enable contact -> OFF)
In this case, the fireplace first enters economy mode operation, and then automatically switches off when the desired room temperature (detected with
KLOVER remote control) is reached.
...to operate the boiler 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 fireplace display (menu 4 enable contact -> ON)
In this case, the fireplace first enters economy mode operation, and then automatically switches off when both temperatures have been reached.
...to operate the fireplace 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 fireplace display (menu 4 enable contact -> ON/OFF).
In this case, the fireplace 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 operate the fireplace not with an external thermostat, 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 fireplace display (menu 4 enable contact -> ON/OFF). The contact must obviously be bridged
(provided for in the factory).
Only when reaching the temperature set in “SET H2O” or “SET DHW” does the fireplace enter economy mode operation.

INITIAL START-UP
Filling the system for the first time
After connecting the fireplace, 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 fireplace;
Open the “boiler body and system load cock” to load the system. Gradually allow any air to escape from the central heating cooker through with “manual
air release valve”; Optimum working pressure is 1.2 bar;
If necessary, very slowly loosen the pump vent plug, draining the fluid for a few seconds;
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 hydraulic joints for the first few days of operation.
The fireplace can be emptied using the “boiler body and system drain cock” .
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 insert to the electrical system using the cable supplied;
Set the “power ON/OFF switch” on the RH side of the insert 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 fireplace runs out of pellets), we recommend using what is mentioned in MENU 07 – INITIAL LOAD;
Switch the fireplace on using the ignition button on the Control Panel. See the instructions below.
It is recommended to use high quality pellets so as not to impair the fireplace's features. Damage caused by poor-quality pellets shall not be
covered by the warranty.
Fireplace insert ignition cycle
Pressing button 4 (ON/OFF) for a few seconds starts the ignition cycle. After a while, the display shows “START”, and the flue gas intake device and ignition
resistance switch on. After 40 seconds, the appliance enters a pre-load phase ( “PELLET P-LOAD”) useful to quickly fill the brazier with pellets. The
fireplace goes into “FLAME STAND-BY” after the pre-load phase. 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. After these phases, the fireplace enters the work mode at the pre-set power value.
If the pellets do not ignite, the fireplace enters the “NO IGNITION” alarm mode.
The alarm may also occur if the brazier is dirty; in this case, clean the brazier and re-start the fireplace.
Summary:
The ignition cycle can last 25 minutes max. and is divided into four steps:
1 - START
:
Flue gas extractor start up
duration - 40 seconds
2 - PELLET P-LOAD
:
Pellet pre-load (initial continuous load) and resistance ignition
Pr40 = pre-load time in ignition
3 - FLAME STAND-BY
:
pellet load (intermittent load) and heater element in operation
Pr01 – Pr40 = ignition cycle maximum time – Ignition pre-load time
4 - FIRE PRESENT
:
Heater element switches off and flame stabilization
Pr02 = start time
The fireplace switches into working mode at the power output set during ignition via buttons 1 and 2.
19
Fireplace insert working cycle
During the working phase, by pressing 1, you can set “SET H20” or the water working temperature on the fireplace. When this temperature is reached, the
fireplace enters economy mode operation “T-H2O ECONOMY”.
5°C before reaching the temperature set on “SET H20”, the fireplace starts modulating output by decreasing the pellet intake and reducing the flue gas
suction 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 when the temperature reaches 75°C.
“T-H2O ECONOMY”.
The fireplace now switches itself off automatically if at least one of the following conditions obtains:

it remains in economy mode operation “T-H2O ECONOMY” for a time set on Pr44 (30 minute default setting).

If it exceeds the temperature differential set in Pr43 (factory setting 5°C) or H2O temperature > ( “SET H2O” + Pr43 ).
The fireplace automatically starts up again if the following condition obtains:

The temperature falls below the temperature differential set on Pr43 (5°C default setting) or H2O Temperature < ( “SET H2O” – Pr43 ).
If the above condition occurs when the fireplace is still completing the switch-off cycle, 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 parameter
table).
Switching the fireplace off
Pressing button 4 (ON/OFF) switches the fireplace off. The display will show “FINAL CLEANING”. Pellet loading is stopped, turning off the gear motor. The
flue gas intake device speed is increased to maximum and switched off after the equipment cooling, displaying "OFF”.

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 of the device. We recommend running the appliance at maximum power for the first few days of operation.

The boiler body is treated with an anti-rust paint to protect it against oxidation during long periods of disuse. After initial start-up, this paint no longer
preserves these features and any wear of the paint inside the combustion chamber should not be regarded as a product defect.

Any noise heard may be due to the boiler body's settlement expansion and should not be regarded as a manufacturing defect. This noise is heard
especially when igniting and switching off the appliance.

If ignition fails, empty the pellets out of the brazier; only then should you reignite the appliance, to avoid gasification which can lead to an explosion
during ignition.
21
WHAT HAPPENS IF..
…the pellets do not ignite
In the event of ignition failure. The “NO IGNIT-“ alarm message appears.
Cancel the alarm and reset the fireplace to standard condition by pressing key 4 for a few seconds.
...the fire door is open or not properly closed
If the door is left open or closed improperly, the gearmotor cannot be powered electrically, therefore the fireplace does not switch on. If the fire door is
opened during normal operation, the fireplace activates the “SAFETY-TEMP ” alarm and burns all the pellets in the brazier.
...the fireplace is not properly engaged
If the fireplace is not properly engaged with the flue gas connection, the gearmotor is not powered and hence the fireplace does not ignite; the
“SAFETY-TEMP” alarm is activated.
...the flue pipe is dirty, blocked or not correctly installed
If the flue is dirty, blocked or incorrectly manufactured, the gearmotor cannot be powered electrically thus the fireplace will not switch on. If the flue pipe
becomes obstructed during normal operation, the fireplace activates the “DEPRESS.-FAILURE" alarm and burns all the pellets in the brazier.
...the fireplace is overheated
If the fireplace water is overheated, the gear motor is not electrically powered because the manual reset thermostat cuts in. If this happens when the
fireplace is working, it will go into the “NO PELLET” alarm (immediate shutdown). It is therefore necessary to rearm the thermostat before switching the
stove on again.
...power failure
If a power outage occurs for a shorter time than Pr48, when power is restored, the fireplace will immediately re-start in the working mode it had been
operating with before the outage (recovering the set working output).
If the outage lasts longer than Pr48, when power is restored, the fireplace will enter the “STOP FIRE” (stand-by) mode running all the switch-off cycle
until cooling. When this phase is over, the fireplace can be restarted resuming work at the set output.

use of non-original spare parts or parts not suitable for this type of product.
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 accepted only if the warranty coupon (commissioning report) is completed and legible in all its parts by the authorized Technical
Assistance Centre. For the validity of the warranty, equipment commissioning must only be carried out by the authorized Technical Assistance Centre within
3 months of the date of purchase and no later than 30 days from date of installation.
The competent law court for settling any disputes is the Court of Verona.
