Smoke Control Areas

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 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. Further information on the requirements of the Clean Air Act can be found here : http://smokecontrol.defra.gov.uk/ 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”

“The Klover SMART 120 (models - SM120, SM120-BP, SM120-P, SM120-B) have been recommended as suitable

for use in smoke control areas when burning wood pellets.”

The manufacturer reserves the faculty to make any modifications to the product in order to improve its performance. The given heat output can change according to the pellet used.

Page 16

Pellet features

The central heating cooker has been tested with all types of pellets available on the market. The

pellets used must have the following features:

 Diameter 6 mm;  Maximum length 35 mm;  Maximum humidity content 8 – 9 %;  100% wood. Total absence of additives.  1.1 % maximum ash residue

For a good performance of the central heating cooker, we recommend using good quality pellets. Pellets should be poured into the tank using a shovel, and not directly from the bag.

To recognise good quality pellet, make sure:

 It is made up of constant diameter cylinders, and has a smooth, glossy surface;  There is not a lot of sawdust inside the packaging;  If the pellet is poured into a container full of water, it will sink if it is good quality, and

it will tend to float if it is not;

 The references of quality certifications and in particular compliance with

international standards such as EN 14961-2 Wood pellet class A1-A2 (maximum moisture level of 10%), should be indicated on the packaging;

 Packages are intact as pellet tends to absorb humidity. Humidity not only reduces

the calorific value and increases flue gas, but swells the product, which could create problems in the central heating cooker.

International standards must be complied with for pellet manufacture as already happens in France, Austria, Germany, and recently some Eastern countries, which also have to comply with DIN 51731 and O-NORM M7135 standards in the production phase. These standards establish the minimum values to check pellet quality. In Italy there are not official rules, but it is recommended using pellet meeting the previously-mentioned standards.

The use of poor pellet or any other material can damage the central heating cooker features,

voiding the warranty and exempting the manufacturer from all responsibility.

In order to ensure problem-free combustion, the pellets must be kept in a dry place.

Page 17

REQUIREMENTS OF THE PLACE OF INSTALLATION

Positioning

The first step to ensure the best installation of the central heating cooker is to identify an excellent

location; in this regard, take the following elements into account:

 The possibility of creating an external air intake;  The possibility of creating a straight flue with possibly coaxial central heating cooker

output;

 Proximity to the main liquid collector and /or the boiler if one already exists);  Proximity or ease of connection to the water system;  Ease of access for cleaning the central heating cooker, the exhaust gas ducts and the

flue.

The central heating cooker must be installed on a floor with suitable load capacity. If the existing

building does not meet this requirement, appropriate measures (e.g. load distribution plate) must be

taken.

Once you have found the best location for the cooker arrangement, position it following the directions

given below.

The minimum safety distance from flammable materials must be at least 200 mm from the sides

and back of the central heating cooker.

Spaces around and above the central heating cooker

The figure below shows the minimum measures to be met when positioning the central heating

cooker in relation to the walls.

PARETE POSTERIORE

PARETE LATERALE

50 cm

The hood assembled above the central heating cooker must be at least 70 cm away from its upper

part (also see technical features in the instructions manual attached to the hood to be installed).

Furniture and mobile objects must be positioned at least 10 cm away from the equipment side walls;

these items should be easily removable in case of maintenance work. In any case they should

be moved before any operation by the authorised Technical Assistance Centre for easy

access to the equipment sides.

Hanging shelves or building countertops above the central heating cooker, especially if the latter

have low heat resistance, is not recommended. Shelves or countertops should in any case be at

least 70 cm away from the upper cooking plate.

Protect all structures that can catch fire from heat radiation.

REAR WALL

LATERAL WALL

Page 18

External air vent

While running the central heating cooker draws air from the room in which it is installed; It is

essential, therefore, that the air is restored through an external air vent.

An air vent must be made at the back of the equipment (15 cm diameter hole), at a height of

20 cm from the ground, near the central heating cooker intake pipe (see figure A and

Connections technical sheet).

if the rear external air vent does not draw air directly from outside the home, a further hole in an

adjacent room must be made provided it communicates with the outside of the home (minimum

diameter 15 cm).

If an air vent cannot be made on the heating cooker rear wall, keep it at least 5 cm away from the

rear wall and drill a hole (diameter as above) in a perimeter wall of the room where the central

heating cooker is installed.

The hole must be protected externally with a fixed grid. Periodically ensure the grid is not

obstructed by leaves or the like, thereby preventing air passage.

The UNI 10683 standard PROHIBITS the withdrawal of combustion air from garages, fuel

stores, or businesses involving a fire hazard.

Do not connect the external air vent to the central heating cooker through piping. If there are

other heating or suction appliances in the room, air vents must ensure the necessary air

volume required for the proper operation of all devices.

In the room where the central heating cooker is to be installed, only sealed equipment (e.g. C

type gas equipment, according to the UNI 7129 Standard), or equipment that does not cause

depression with respect to the external environment can be kept or be installed.

Extractor fans may cause a malfunction in the central heating cooker when used in the same room

or operational space as the cooker.

Figura A

Flue and connection to the same flue - Chimney

The flue is a key element for the proper operation of the central heating cooker. The minimum section

of the flue must be the one indicated in the central heating cooker specifications (120 mm). Each

central heating cooker must have its own flue, without other intakes (boilers, fireplaces, stoves,

etc…). The flue size is closely related to its height, to be measured from the central heating cooker

outlet to the chimney base. To ensure draught, the chimney flue outlet surface must be twice as big

as the flue section.

Page 19

The exhaust duct of the combustion products, generated by the forced draught unit, must meet the

following requirements:

 Be airtight to combustion products, waterproof, and properly insulated according to the

conditions of use (see UNI 9615);

 Being made of materials suitable to resist normal mechanical stress, heat, action of the

combustion products, and condensate if any;

 Have ascending development after the vertical tract for the entire remaining path with a

5% minimum slope. The sub-horizontal development part must not have a length greater than ¼ of the effective height of the flue or chimney, and in any case not be longer than 2,000 mm;

 Have a preferably circular internal section: square and rectangular sections should have

rounded corners with a radius larger than 20 mm;

 To have constant, free and independent internal section;  To have rectangular sections with a 1.5 maximum ratio between 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;

 To mount exhaust channels (stretching from the unit to the flue inlet), elements of non-

combustible materials suitable for resisting combustion products and any condensation must be used;

 It is forbidden to use fibre cement pipes to connect the appliances to the flue;  Exhaust channels must not pass through rooms in which the installation of combustion

appliances is forbidden;

 When mounting exhaust channels, make sure they are flue gas sealed;  Installation of horizontal sections should be banned;  The usage of elements in counter-slope is forbidden;  The exhaust channel must allow soot recovery or cleaning using a swab, and must have

a constant section;

 It is forbidden to run other air supply channels and pipes for plant engineering use into the

exhaust channels, even if oversized.

The chimney is a device crowning the flue, used to facilitate the dispersion of combustion products.

It must meet the following requirements:

 Have a useful outlet section not smaller than twice that of the flue on which it is inserted;  Be shaped so as to prevent the penetration of rain and snow into the flue;  Be built in such a way that combustion discharge is ensured even in case of wind in any

direction and angle.

The outlet height (where height corresponds to the top of the flue, regardless of any chimneys) must

be beyond the so-called reflow area in order to avoid the formation of counter-pressures preventing

the free discharge of combustion products into the atmosphere.

It is therefore necessary to ensure compliance with the minimum heights shown in the following

figures:

FURTHER SPECIFICATIONS TO BE CONSIDERED

The central heating cooker works with the combustion chamber in depression; it is essential that the

exhaust pipe is hermetically sealed.

We recommend using rigid stainless steel pipes, with sealing gaskets having a minimum diameter of

120 mm.

The pipes must be double-walled or adequately insulated with rock wool. The maximum

temperature of the pipe must not exceed 70 °C.

TO ENSURE PROPER FUME DISCHARGE PROVIDE FOR AN INITIAL VERTICAL TRACT OF AT

LEAST 1.5 METRES.

Each change of direction must be carried out with a T-shaped fitting and inspection cap.

Pipes must ensure sealing against smoke leakage via gaskets resistant to 250 °C.

Fix the pipes to the wall with suitable relevant metal collars to avoid any vibration.

WARNING: IT IS FORBIDDEN TO INSTALL DRAUGHT REGULATING VALVES (BUTTERFLY

VALVES).

There are two solutions for the connection to the flue:

SOLUTION 1 – REAR FLUE GAS OUTLET

Page 21

SOLUTION 2 – UPPER FLUE GAS OUTLET

If a “conventional” flue is used to discharge flue gas, make sure it is in good working order and

complies with the standards currently in force. 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

properly sealed.

When mounting the flue, do not make more than 4 changes of direction, including the initial T-

shaped fitting. The maximum allowable length of the horizontal tract is 2 metres. Before

carrying out horizontal movements, make a vertical, at least 1.5 metre-long tract.

Page 22

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.

Product safety is obtained when it is properly connected to an efficient earthing system.

When connecting to the mains power supply, provide a differential magnetic circuit breaker 6 A – Id

30 mA switch with an appropriate breaking load. Electric wiring including grounding must be

performed after removing the mains power supply.

When building the system, remember that cables must be laid in an unmovable way and away from

parts subject to high temperatures. During the final wiring of the circuit, only use components with an

appropriate degree of electrical protection.

KLOVER srl disclaims all liability for damage to people, animals, or property resulting from

failure to properly ground the central heating cooker in compliance with IEC standards.

The electronic control unit manages and controls all the central heating cooker features ensuring

excellent operation of the entire equipment at any time.

Inspection of a possible coupled boiler

If the Smart 120 central heating cooker is to be coupled with a previously installed boiler in the

system (e.g. wall-hung gas boiler), it must be ensured that when the pellet central heating cooker

takes over doing the heating the boiler stops. This is to make sure that you do not have to add up the

heat output in the two appliances installed in the system. This is why our set-up intervenes on the

coupled boiler when the pellet central heating cooker heating pump starts. In this way, there will never

be two boilers operating simultaneously in the same system. The coupled boiler will however always

be used for the production of domestic hot water.

The two wires prepared on the back of the central heating cooker (blue and brown wires) will

have an output voltage of 220 V when the pellet central heating cooker pump is working, and

no voltage when the pump is at a standstill.

Therefore, it is easy to connect the 2 wires to a relay that will control the Room Thermostat inlet of the

coupled boiler.

Control of a possible three-way motorized valve for the DHW system

The Smart 120 central heating cooker is equipped as standard with a control for a possible 3-way

motorized valve to be installed on the domestic hot water circuit. A 4-wire cable with protected faston

connectors 4 wires escapes from the rear part of the central heating cooker, which can be used to

control this valve. The four wires in the cable have different colours, and precisely:

1. Blue wire = COMMON TO 3-WAY VALVE

2. Black wire = PELLET CENTRAL HEATING COOKER SIDE

3. Brown wire = GAS BOILER SIDE

4. Yellow/green wire = GND

Below find a connection example using a 3-way valve with spring return. Remember that the pipe

connection must be made in a way that when the valve is at rest, the water passes from the gas

Page 23

boiler. Only when the pellet central heating cooker temperature is sufficient (the value is set from

control panel) is the 3-way valve powered, and so closes the gas boiler circuit and opens the Smart

120 central heating cooker circuit.

NOTE: The brown wire can be used to control any service relay.

Connection to the room thermostat

A bridge clamp is installed on the rear of the central heating cooker (free contact), which is useful to connect any 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.

OPERATION PRINCIPLE

Open contact:

1. The central heating cooker switched directly to economy mode operation “TOFF ECONOMY” minimizing working output.

2. The central heating cooker pump turns off.

3. The temperature in the central heating cooker increases due to thermal inertia until reaching the temperature set on “SET H2O” and displaying “TH2O ECONOMY” on the screen.

4. The central heating cooker will now automatically switch off if there is at least one of the following conditions:

 If 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 on Pr43 (factory set value

5°C) or H2O Temperature > (“SET H2O” + Pr43)

NOTE: The pump is calibrated to start at temperatures ≥ 83°C in all conditions (see parameter table). WARNING: If a room sensor on the remote control is also enabled (see page 44 – “Menu 04”), the

central heating cooker enters the economy mode when both cases are satisfied. The room thermostat operation is excluded if one of the three OVEN OUTPUT VALUE is set.

The central heating cooker will switch on automatically if both the following conditions occur:

 If the contact of the room thermostat is closed.  If it goes below the temperature differential set on Pr43 (5°C default setting) or Temperature H2O <

(“SET H2O” – Pr43). If the above-described condition occurs when the central heating cooker is still running the switch off cycle, it is appropriate to wait until it runs out.

PLUMBING CONNECTION

The plumbing connections must be made in a rational way using the connections on the central heating cooker template. To facilitate the connection of the pipes, we have provided all plumbing connections on the rear left side, leaving space to easily make the appropriate connections. Remove the left side of the central heating cooker to access the “side technical compartment” (see

fig. on p. 10 and 34) to facilitate the plumbing connection.

The central heating cooker can be coupled to any other boiler already installed in the system including all necessary safety devices and wiretaps according to the system used.

NOTE: The central heating cooker can be installed with a closed expansion vessel equipped with a device for stopping fuel loading, a safety manual reset thermostat and an audible alarm activated if temperatures are too high.

The central heating cooker can be installed in the same room as another boiler only if it has a sealed chamber.

THE CENTRAL HEATING COOKER MUST BE INSTALLED EXCLUSIVELY BY QUALIFIED ENGINEERS. STRICTLY COMPLY WITH THE INSTRUCTIONS GIVEN IN THIS GUIDE; FOR ANY

DOUBT CONTACT THE TECHNICAL ASSISTANCE CENTRE.

THE MANUFACTURER DISCLAIMS ALL RESPONSIBILITY FOR DAMAGE CAUSED BY IMPROPER INSTALLATION.

THE NETWORK WATER INLET PRESSURE MUST NEVER EXCEED 3 BAR; RECOMMENDED WORK 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 WATER SPECIFICATIONS.

CLEANING AND MAINTENANCE

Precautions before cleaning

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

 The central heating cooker is off and has cooled down completely;  Ash is completely cold;  Before re-starting the central heating cooker, re-install all previously disassembled parts.

For cleaning operations, personal protective equipment should be worn.i.e. gloves, goggles and dust masks, as directed in eu 89/391/EEC.

Cleaning frequency depends on the type and quality of pellets burnt. Therefore, the schedule reported below may vary.

Any central heating cooker problem resulting from failure to clean it will not be accepted as collateral.

Routine cleaning (1)

The central heating cooker requires periodic cleaning to be carried out at least every 20 working hours or after 3-4 ignitions, to always ensure efficiency and excellent operation.

Carefully clean the brazier from combustion residues, by removing it from its seat.

Ceramic glass cleaning

Always clean the glass when the central heating cooker is off and completely cold. Use a damp cloth and specific detergent for ceramic glass. Do not use abrasive sponges.

Flue cleaning

This operation must be performed at least twice a year, in early and mid winter, and whenever necessary. You need to check for obstructions in the flue before switching the central heating cooker on, following a long period of disuse. If cleaning is not performed, the operation of the central heating cooker and its components may be impaired.

The frequency of the central heating cooker and flue cleaning depends on the quality of the pellets used.

USE TOP QUALITY PELLETS TO OBTAIN THE BEST RESULTS.

Maintenance

Systematic, timely maintenance is a critical component for correct operation, excellent thermal performance and duration of the appliance over time. Therefore, it is recommended that a qualified engineer checks the central heating cooker at least once a year at start of season.

It is advisable to agree an annual contract for product maintenance with the Authorised Technical Assistance Centre (TAC).

Example:

In this condition... ...if you want to operate the central heating cooker with KLOVER remote control room temperature only::

 enable the room sensor on the remote control (stove settings menu +> Enable room sensor -> ON)  disable the boiler thermostat contact on the central heating cooker display (menu 4 enable contact ->

OFF) In this case, the central heating cooker first enters economy mode operation, and then automatically switches off when the desired room temperature (detected with KLOVER remote control) is reached.

...if you want to operate the central heating cooker with KLOVER remote control room temperature and with boiler thermostat:

 enable the room sensor on the remote control (stove settings menu +> Enable room sensor -> ON)  enable the boiler thermostat contact on the central heating cooker display (menu 4 enable contact ->

ON) In this case, the central heating cooker first enters economy mode operation, and then automatically switches off when both temperatures have been reached.

...if you want to operate the central heating cooker 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 central heating cooker display (menu 4 enable

contact -> ON/OFF) In this case, the central heating cooker 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.

...if you do not want to operate the central heating cooker with 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 central heating cooker display (menu 4 enables

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 central heating cooker

enter economy mode operation.

COMMISSIONING

Filling the system for the first time

After connecting the central heating cooker, fill the system as follows:

 Check tightness of all piping, the expansion vessel, and the circulation pump;  Open “manual air release valve” of the central heating cooker, located on its left side (see fig. on page

10);

 Open the “boiler body and system load cock” (see fig. on page 8) to load the system. Act very slowly to

allow any air to escape from the central heating cooker through the “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 deaeration system to ensure that there are no air bubbles.

After installation, check the tightness of all hydraulic joints. When installation has been completed, it is advised, for the first days of operation, to check the tightness of all

hydraulic joints. The central heating cooker system can be emptied through the “boiler body and system drain cock” located

inside the “hydraulic compartment” below the cooking oven (see fig. on page 8).

During periods of intense cold it is appropriate that the heating system remains in operation. In the case of a prolonged absence, antifreeze must be added to the heating water, or the system 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 mains connection

Perform the following steps:

 Connect the central heating cooker to the electrical system using the cable supplied;  Put the “main ON/OFF switch” (see fig. on page 9) located inside the “technical compartment” of the

central heating cooker in position “׀” (ON);

 Fill the pellet tank; for the first start ever, to avoid wasting the time required for filling the entire screw

feed channel (this should be done every time the central heating cooker remains without pellets), we recommend using what is mentioned in MENU 07 – INITIAL LOAD (see page 46);

 Turn on the central heating cooker using the relevant ignition key on the control panel. See the

instructions below. It is recommended to use high quality pellets so as not to impair the central heating cooker

features. Damage caused by poor pellets is not covered by the warranty.

Central heating cooker ignition cycle

Pressing button 4 (ON/OFF) for a few seconds allows starting the central heating cooker ignition cycle. After a while, the display shows “START”, and the flue gas intake device and ignition resistance switch on. After 40 seconds, the central heating cooker moves to a pre-load phase ( “PELLET P-LOAD”) useful to quickly fill the brazier with pellet. The central heating cooker 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 steps, the central heating cooker enters work mode at the pre-set output. In case of misfire, the central heating cooker goes into “NO IGNIT-” alarm.

The alarm may also occur if the brazier is dirty; in this case, clean the brazier and restart the central heating cooker.

Page 49

Summary:

The ignition cycle can last max 25 minutes and is divided into four steps:

1 - START : Flue gas intake device ignition

duration 40 seconds

2 – PELLET PRE-LOAD : Pellet pre-load (initial continuous load) and resistance ignition

Pr40 = Ignition pre-load time

3 - FLAME STAND-BY : Pellet load (intermittent load) and operation resistance

Pr01 – Pr40 = ignition cycle maximum time – Ignition pre-load time

4 - FIRE PRESENT : Resistance switch-off and flame stabilization

Pr02 = start time The central heating cooker switches into working mode at the output set during ignition via buttons 1 and 2.

Central heating cooker working mode

During the working phase, by pressing 1, you can set “SET H20” or the water working temperature in the central heating cooker. When this temperature is reached, the cooker enters the economy mode operation “T-H2O ECONOMY”.

Before reaching the temperature set on “SET H20”, the central heating cooker starts modulating output by decreasing the pellet intake and reducing the flue gas suction speed.

Example: “SET H2O” set at 75 °C Working output set at 5

- Working output automatically changes to 4 when temperature reaches 71°C.

- Working output automatically changes to 3 when temperature reaches 72°C.

- Working output automatically changes to 2 when temperature reaches 73°C.

- Working output automatically changes to 1 when temperature reaches 74°C.

- Working output automatically changes to economy mode operation “T-H2O ECONOMY” when temperature reaches 75°C.

At this point, the central heating cooker will shut off automatically if at least one of the following conditions occurs:  If it remains in the economy mode operation “T-H2O ECONOMY” for the time set on Pr44 (30 minute

default setting).

 If the temperature differential set on Pr43 (5°C default setting) or H2O Temperature > (“SET H2O” +

Pr43) is exceeded.

The central heating cooker will automatically switch on if:

 It goes below the temperature differential set on Pr43 (5°C default setting) or Temperature H2O <

(“SET H2O” – Pr43).

If the above-mentioned condition occurs when the central heating cooker is still carrying out the switch-off cycle, please wait until it runs out.

The cleaning cycle of the brazier (displayed under “BRAZIER CLEANING”) is done at predetermined time intervals for an established period (see parameter table).

Page 50

Producing domestic hot water (suitable models only)

Domestic hot water is produced instantly via a double heat exchanger immersed in water in the central heating cooker. Therefore, to have DHW, the central heating cooker must reach a temperature of at least 60°C.

Set the central heating cooker in DHW output mode “DHW” if a large amount of domestic hot water is required. The function of the “DHW” output mode is to postpone the heating pump start-up at higher temperatures, so as to transfer all the heat produced at these temperatures to domestic hot water. Press 5 to set the pump starting temperature and use keys 5 or 6 to change the “SET DHW” temperature (we recommend keeping this temperature at 70–75°C) (also see page 51). If “DHW” output mode is manually set, the central heating cooker must be reset with working output from 1 to 5 when domestic hot water is no longer required.

The central heating cooker is equipped with a predisposition for the connection to a flow switch that automatically sets “DHW” output mode when there is demand for hot water. Conversely, when there is more demand for hot water, the central heating cooker automatically returns to the previously set working output. Contact the authorised Technical Assistance Centre for the electrical connection of the flow switch.

If water is particularly hard, it is essential to install an anti limescale device at the heat exchanger inlet, to be chosen according to the water characteristics.

Cooking plate/oven output.

Besides setting one of the five available WORKING OUTPUT VALUE (from 1 to 5) and the DHW OUTPUT, pressing button 6 also allows selecting one of the three OVEN OUTPUT VALUE (OVEN 1, OVEN 2, OVEN

3) which can only be set when you want to cook. Therefore, press keys 5 and 6 to set the desired output.

During this operation, the display appears as in the figure below.

Set

2 3 4 5

By setting one of the three available OVEN OUTPUT VALUE, the operation of the room thermostat (or of any other combined thermostat) is excluded. So the central heating cooker will enter modulation mode and then go off only if the temperature set on SET OVEN is reached (75°C default setting - see parameter

tables).

Re-set one of the five WORKING OUTPUT VALUE (from 1 to 5) when you have finished cooking. The oven and cooking plate temperatures reached with laboratory tests are shown in the following tables.

* The temperatures in the tables are approximate and vary depending on the type of pellet burnt and frequency of cleaning the flue gas turn. The temperature may fall by about 20/30°C if food is put into the oven. The temperatures were measured starting with the central heating cooker off and cold; the temperatures may be different from those reported above after several hours of operation.

It is recommended to periodically turn the dripping pan or the cooking grid during cooking to allow a homogenous baking of the food in the oven.

To cook on a cast iron radiant plate, you should place the pot on the hottest point of the plate or in the middle of the circles drawn on it (see figure). Only use flat bottom pots evenly adhering over the base.

Central heating cooker switch-off

Pressing button 4 (ON/OFF) the central heating cooker is turned off. The display will show “FINAL CLEANING”. The pellet load is stopped turning off the motor reducer. The flue gas intake device speed is increased to maximum and switched off after the equipment cooling, displaying "OFF”.

Alarm signals

If there is a malfunction in the cooker the display board will activate an alarm and indicate on the display the type of malfunction that has occurred. The board has the following alarm indications.

DISPLAY

ORIGIN OF ALARM

AL 9 WATER PROBE ACTIVE ALARM

Faulty or disconnected water temperature probe.

AL 2 FLUE GAS PROBE ACTIVE ALARM

Faulty or disconnected flue gas temperature probe.

AL 3 HOT TEMP ACTIVE ALARM

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”.

AL 5 NO IGNIT- ACTIVE ALARM

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

AL 6 NO PELLET ACTIVE ALARM

Sudden shutdown during working mode. When, during work, the flue gas

temperature drops below the minimum threshold (Pr13).

AL 4 FAULTY INTAKE DEV- ACTIVE ALARM

Faulty intake device. When the intake device speed measured by an in-built encoder (tachometer) is equal to 0.

Each alarm condition causes an immediate shutdown. After the time set on Pr11 (alarms delay) the alarm state is reached; press key 4 to reset it.

What you need to know...

Listed below are some things you should know about the equipment:

 It is normal to smell paint from the equipment in the first few days of operation. The first time the

central heating cooker is powered, we recommend keeping the installation room ventilated. We also recommend setting the cooker at maximum power for the first few days of operation.

 The boiler body is treated with an antioxidant paint to protect it against oxidation due to long periods

of disuse. After the first ignition, this paint will no longer have this function, and any wear of the paint inside the combustion chamber is not to be considered a product defect.

 Any perceived noise can be attributed to the boiler body settlement expansion, and is not

considered a manufacturing defect. This noise is primarily perceived during ignition and shutdown.

Page 54

WHAT HAPPENS IF..

…the pellet does not ignite

In the event of a misfire, the “NO IGNIT-“ alarm message appears.

Cancel the alarm and reset the central heating cooker to standard condition by pressing key 4 for a few seconds.

...the fire door is open or closed improperly

If the door is open or closed improperly, the motor reducer cannot be powered electrically thereby preventing the central heating cooker from being ignited. If the fire door is opened during standard operation, the central heating cooker will burn all the pellet in the brazier and then activate the “NO PELLET” alarm (sudden shutdown).

...the flue is dirty, clogged or not properly manufactured

If the flue is dirty, clogged or not properly manufactured, the motor reducer is not electrically powered and therefore does not turn the cooker on. If the flue becomes clogged during normal operation, the central heating cooker will burn all the accumulated pellets in the brazier, and then go into the “NO PELLET” alarm (sudden shutdown).

...the central heating cooker is overheated

If the cooker water is overheated, the motor reducer is not electrically powered and a manual reset thermostat is enabled. If this happens when the central heating cooker is working, it will go into the “NO PELLET” alarm (sudden shutdown). It is therefore necessary to reset the thermostat before restarting the central heating cooker.

...lack of power (black out)

If an outage occurs for a shorter time than Pr48, when power is restored, the central heating cooker will immediately re-start in the working mode it had been operating with before the outage (recovering the set working output). If an outage occurs for a longer time than Pr48, when power is restored, the central heating cooker will enter the “STOP FIRE” (stand-by) mode running all the switch-off cycle until cooling. When this phase is over, the cooker can be restarted resuming work at the set output.
