THE COMPANY
We started in the early 70s in the San Bonifacio a province of Verona. Passion and determination have created a range of safe and innovative products which have enabled a small company to become one of the most popular in Italy and across the main European markets. KLOVER was the first company to conceive and develop a special safety device; the SICURO top system which is the only system able to enable any wood heat generators' installation into closed circuit heating systems. This guarantees safety, in all conditions to the full system, the equipment and the customer. Specialising in producing wood Idro products for domestic heating (thermo cookers/wood thermo stoves, wood fireplaces, wood boilers) since the early years, have aimed to realise pellet and pellet/wood combined Idro products in the last ten years. Some pellet and wood air products (pellet stoves, wood cookers) have also been included in its production in recent years.

SAFETY DEVICES
The safety devices are all those components that intervene on equipment functioning in case of anomalies, regardless of electronic board's state.
3.1
Safety valve
It intervenes in case water in boiler pressure exceeds 2.5 bar.
3.2
Anti-disturbance filter
The anti-disturbance filter is equipped with 2 4A fuses that intervene in case of electric overload.
14
3.3
Power board fuse
The power board is equipped with 4A fuse that intervenes with thermo stove's electric plant in short-circuit or electric overloads (if the two fuses inside the anti-disturbance filter do not intervene).
3.4
Manual re-arm thermostat It disconnects current to motor reducer (pellet load) in case of water in boiler over temperature. It is assembled on pellet tank in air pellet stoves. When it intervenes: Water in boiler temperature ≥ 94°C Pellet tank temperature ≥ 90°C (on air stoves only) In case of intervention; rearm it by loosening the black cap and pressing the button underneath it.
Connected contacts: 2 and C
15
3.5
Flue gas pressure switch It disconnects current to motor reducer (pellet load) in case of insufficient flue gas draught. When it intervenes: • Scarce draught in flue; Incorrectly manufactured flue gas pipe and/or flue; • Obstructed flue. Disconnect the small silicone pipe connected between pressure switch and flue gas intake device crosshead nut to exclude its functioning. Connected contacts: NC1 (normally closed) and COM3 (common). Pressure switch calibration is 0.9 mbar. A pressure switch calibrated at 0.4 mbar is assembled on
3.6

3.8
Level Sensor
17
•
The pellet sensor monitors the level of pellet within the hopper.
•
When pellets are below the level of the sensor an alarm will sound and the LCD screen will indicate 'pellet reserve'; this is to inform you that the hopper is becoming empty and needs refilling.
•
If hopper is not refilled within a set time then the stove will shut down.

SICURO TOP
Sicuro top Nuova Belvedere
Sicuro top thermo cooker/thermo stove.
Sicuro top Bi-Fire
SICURO top is a Klover heating system that exploits the “bain-marie” principle, allowing you to use the home system with a closed expansion vessel, while SICURO top has an incorporated open-vessel, and therefore zero pressure. HOW IT USED TO BE Before the "SICURO TOP" System, to install any kind of wood product onto a household heating system, you had to mount an open expansion vessel on the system (according to current Standards in force). This open vessel discharged pressure that built up inside the product and the piping in case the water boiled due to circumstances such as a sudden black out. This occurred because the wood keeps on burning even without electricity. Open-vessel heating systems are obsolete and are no longer taken into consideration by thermo-technicians and engineers, since they entail various problems which closed-circuit systems do not have. Most significantly the danger caused by boiling over, the elevated heat dispersion, construction difficulties and the incompatibility with last-generation wall-hung gas boilers. THE IDEA "SICURO TOP" was created 12 years ago in the KLOVER workshops in order to offer a line of technologically innovative products, in the forefront and at the same time safe. The System constantly evolved increasing thermal yield and safety. Today we can boast a tested and safe system that has reached a very high level of perfection.
18
THE SYSTEM "SICURO TOP" exploits the “bain-marie” principle, allowing you to use the home system with a closed expansion vessel, while “SICURO top” has an incorporated open-vessel, and therefore zero pressure. The equipment can be integrated into an appliance that is already installed (any type of boiler, even wall-hung gas boilers) or can function as a unique source of heating for the home. The boiler body is the "water chamber" type with exchange elements in direct contact with the flame. The hearth is closed by a ceramic glass door. The combustion chamber is completely surrounded by water (except for the front part and fire top where the cast iron grid is found). The flue gas does a double pass before leaving the equipment (see Flue gas turn diagram). Primary and secondary heat exchangers are installed in the upper boiler body part, respectively to heat the radiators and produce domestic hot water. The heat exchangers are emerged "Bain-Marie" in the water of the appliance which flows into the stainless steel lateral or upper tank, provided with a removable cover so that the heat exchangers or float can be controlled. A specially-designed magnesium anode protects the boiler body and the stainless steel heat exchangers from stray currents and galvanic corrosion. SIMPLE BUT EFFECTIVE OPERATION The fire and flue gas heat the water inside the boiler body which in turn heats the water circulating in the upper or lateral heat exchangers (primary heat exchanger in 22 mm diameter stainless steel pipe for heating system and secondary heat exchanger in 14 mm stainless steel pipe for DHW system). Control of the water running inside the primary heat exchanger (for radiators) is managed by the electronic control unit, while the water running in the secondary heat exchanger (DHW) is assured by the pressure of the water mains or by the autoclave, if needed. ZERO PRESSURE There is no longer the danger of pressure building up if the water boils. The pressure inside the boiler body is zero. The thermo stove is equipped with an overflow tube which provides safety in case of boiling, discharging the excess water from the upper tank. The equipment is provided with automatic load float for water top-up. Listed below are the advantages of the SICURO TOP system: 1. Total safety. SICURO top works at zero pressure and, therefore, does not show risks due to boiling of all products on the market, even without electric energy. 2. Easy assembly. The SICURO top system does not require open-vessel on system. It can be combined to any type of boiler. It is extremely easy to install for the plumber. 3. Removable heat exchangers. The two stainless steel heat exchangers installed in the steel tank are the "core" of the system and can be removed for their replacement if faulty. 4. Total absence of condensate. Condensate does not form inside the boiler body as temperature variations are minimal during normal functioning, difference of any other product. This is a specific feature of the SICURO top system.
19
5. Creosote. Creosote, tar deposit formed by combustion flue gas in contact with condensate, is the main factor in any boiler yield loss. Creosote forming is minimal with the SICURO top system making yield constant in time. 6. Reduced wood consumption. Exploiting heat produced by combustion to maximum, we have lowered wood consumption to minimum with significant economy saving compared to all other used fuels.

ELECTRIC SET-UPS
5.1
Connection for coupled boiler control Standard set-up
STATO INIZIALE Fili isolati
STATO FINALE Fili non isolati Two wires (blue and brown) are present at back of thermo stove for control of eventual coupled boiler. The two wires prepared on outlet will have a 220V voltage when the thermo stove pump functions (as connected in parallel to pump), no voltage when the pump is at a standstill. It is therefore easy to connect the two wires to a relay controlling the Room Thermostat inlet of the coupled boiler.
Optional set-up using a Stove-stateboard The Stove-state-board is an optional device for controlling a ventual coupled boiler through electric connection parallel to the equipment's flue gas intake device. (The first component to switch-on and last to switch-off) It allows ignoring that the intake device has a voltage that varies between 70 and 230 V, making it unsuitable for switching on a relay or 230V loads. It is a component realised and supplied on request. Useful for avoiding repeated stresses of the coupled boiler's T.A. contact given by continuous system pump ignitions and switchoffs (particularly in initial phase with cold system) if a standard supplied connection is used. Connect the two wires with faston and fastoncover in parallel with thermo stove's flue gas intake device and the two-pole clamp (free contact) (green clamp in image at side) must be directly connected to coupled boiler's Room Thermostat inlet. Our Room Thermostat contact opens when the thermo stove's flue gas intake device functions (or upon product ignition), therefore switching off the coupled boiler. W hereas, when flue gas intake device switches off (or after thermo stove switch-off and cooling), our Room Thermostat contact closes activating the coupled boiler.

INSTALLATION MODE
7.1 Spaces around and above the equipment are extremely important particularly for safety and correct equipment functioning. It is essential for Technical Assistance Centre's access to any part of the equipment to have minimum distances from fixed walls.
The space existing between the walls of the insert and the hearth compartment can be closed via a compensation frame that must be easily removable if maintenance is to be performed on the insert. It is recommended to make lateral or rear inspections for any maintenance.
26
The distances to be left from lateral and rear walls are given in the following table. EQUIPMENT DEA – DEA ECO DIVA Air STAR 14 STAR 18 DIVA DIVA MID DIVA PLUS MAGNIFIKA PELLET FIRE PLACE 18 SMART 80 SMART 120 BI-FIRE BI-FIRE MID PELLET BOILER 24 PELLET BOILER 35

* Upper distance is particularly essential for cleaning of flue gas turn via knobs and eventually to remove the steel sides. Any not respected distance must be reported in the specific commissioning reports. Klover Srl warranty will not cover any intervention foreseeing equipment disconnection if minimum distances are not respected.
27
7.2
Air vent
The air vent is a fundamental component for correct equipment functioning. The essential technical features are: • Minimum diameter of 15 cm (20 cm in case of BI-FIRE and BI-FIRE MID). • Must not be directly connected to the equipment. • Must not be obstructed and, if assembled on external grid, this must be of "large mesh" type. • It must guarantee the necessary air volume independently from other heating or intake devices installed in the room. • The UNI 10683 Standard PROHIBITS the withdrawal of combustion air from garages, combustible material warehouses, or from businesses where there is a fire hazard. • Only sealed equipment (e.g. C type gas equipment, according to the UNI 7129 Standard) or equipment that does not cause lower pressure compared with the external environment can pre-exist or be installed in the place where the equipment must be installed. When used in the same room or space where equipment is found, extractor fans can cause functioning problems to it. External air intake with sealed fittings is extremely important and essential for fire products, particularly in modern homes. Two solutions are possible for realising air vents: • Direct intake, meaning directly connected (e.g.: with flexible) to stove (NOT RECOMMENDED) Advantages: perfect flame oxygenation, less ash- disadvantages: rain-water and wind danger (we recommend externally ending with a 90° curve facing downwards); excessively low external temperature danger (with consequent ignition problems and calorific yield decrease). • Intake in room not connected by free in the room (RECOMMENDED) Advantages: oxygenation of air we breathe and good stove functioning; - disadvantages: cold air in room therefore we recommend air intake to be near the equipment. Any anomaly or missing air vent must be reported in the specific commissioning reports. Klover Srl warranty will not cover any intervention for lack of air vent.
28
If it is not possible to realise the air vent at back this can be realised in a perimeter wall to the room where the equipment is installed, as long as the covering has adequate air gap communicating with the rear part where the intake pipe is present.

Flue and flue gas pipe
The flue and flue gas pipe are essential for equipment good functioning. They must satisfy the following requisites: • Sealed from combustion products, waterproof and adequately isolated. If the flue is installed externally or in a cold room (e.g. boiler room) it is absolutely necessary that it is insulated to avoid the flue gas cooling and condensate forming. • Realised with suitable materials that resist to normal mechanical stresses, heat, action of the combustion products and any condensate. The installation of aluminium pipes is strictly forbidden. • Have smooth and circular internal section. • Have sub-horizontal tracts with minimum gradient of 5% and maximum length of 2 m (horizontal tracts • are not admitted for BI-FIRE and BI-FIRE MID). • The installation of draught regulation valves is strictly forbidden. • Have maximum 4 changes of direction (maximum 2 changes of direction at 45° on BI-FIRE and BI-FIRE • MID). • Wall flue gas exhaust is forbidden.

THE FUEL
10.1
The pellet
The used pellet must have the following features: • Calorific value ≥ 4.9 kWh/Kg = 4.223 Kcal/Kg • Diameter 6 mm • Maximum length 30 mm • Maximum humidity content 10 % • 100% wood. Total absence of additives • 1.1 % maximum ash residue The use of poor pellets or pellets made of any other material can lead to damage of the thermo stove functions and can also make the warranty null and void and make the manufacturer exempt from all responsibility. In order to recognise pellet of quality it is necessary that: • It is manufactured with constant diameter cylinders and it has a smooth and glossy surface; • There is not a lot of sawdust inside the packaging; • •
•
If the pellet is poured into a container of water it will sink if it is a quality pellet, while if it is not, it will tend to float. The conditions of the quality certification and in particular the compliance with international standards such as the DIN 51731 and the O-NORM M7135 are written in the packaging; the new reference standard is EN PLUS 14961-2.
Packages are intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value and increases exhaust gas, but it also swells the product which could create problems in the thermo stove.
In order to guarantee combustion without problems the pellets must be kept in a dry place. Pellet colour can also help identify quality in most cases: - Dark pellet has higher calorific value but it is too dirty, therefore not recommended. - Light pellet has lower calorific value but with low ash residue, therefore recommended.
We recommend pouring pellet into the tank using a shovel and not directly from the bag
39
10.2
The wood
The used wood must have the following features: • Calorific value ≥ 4.4 kWh/Kg = 3.800 Kcal/Kg • Maximum length 40 cm. • Maximum humidity content 20% (2 year seasoning at least). • Avoid resinous woods. • Keep in a dry place. For heating purposes, check wood features satisfy some important requisites that must not be ignored, particularly the correct seasoning or drying. In other words, the wood must have the correct amount of humidity, around 10-15%, therefore the period of the year in which it is felled also becomes important. This should coincide with the winter period. Correct seasoning (at least 2 years) allows having a fuel with excellent yield and not very polluting. It must be kept in covered, well-aired places, already cut appropriately into pieces suitable for the hearth of the thermo stove. For heating purposes, the wood to be burnt has different features according to the plant variety from which it is obtained. Not all woods are the same and the features regarding drying time and calorific value vary from plant to plant. The calorific value depends on the level of humidity and its density. Woods of excellent quality are beech, ash, carpine and acacia. Avoid resinous woods as they excessively dirty the equipment jeopardising duration in time.
11. MAINTENANCE 11.1
Periodical cleaning of flue gas turn
• Routine cleaning: to be performed at least every 20 hours of functioning or after 3-4 ignitions. • Extraordinary cleaning: to be performed at least every 15/20 days. • Yearly cleaning. The "USE AND MAINTENANCE" manual of each product gives the cleaning modes.
11.2
Periodical cleaning of pellet tank
It is essential to remove the sawdust deposit on the base of the pellet tank at least every 15/20 days for the equipment to correctly function. This is essential to avoid pellet compressing therefore blocking the screw feed. The pellet tank and screw feed must be emptied at the end of every season and re-filled upon subsequent start of season.

Guarantee equipment adequate draught and good functioning by periodically cleaning the flue gas channels (twice per season). This also avoids the so-called soot fire: meaning ignition of unburnt parts deposited inside that, upon reaching of high temperatures, can damage gaskets jeopardising seal. More frequent cleaning is required in case of long tracts, particularly horizontal.

Part 2: Troubleshooting Klover pellet stoves 1. You’ve just installed a PB35 in a badly insulated outbuilding and the boiler keeps failing to ignite. What could you do to stop this from happening?
2. A customer calls to tell you they’ve tried turning on their Star 14, it displays; ‘fun asp’ and the auger light comes on. However, no pellets are being dropped into the brazier. What could be the problem?
3. A Smart 120 is displaying; ‘AL6 no pellet’. Other than the hopper running out of pellets, what other reasons could prompt this alarm to be displayed?
4. You’re commissioning a Klover pellet boiler. The demand from the programmer has been terminated, but the boiler is still running as normal with the display reading; ‘t-eco off’. What parameter needs to be adjusted?
