Characteristics of the fuel

Wood pellet is a fuel made of pressed wood sawdust, often recovered from processing scraps of carpentries. The material used

cannot contain any extraneous substance such as, for example, glue, lacquer or synthetic substances.

The sawdust, once it has been dried and cleaned from impurities, is pressed using a die with holes: as a result of high pressure, the

sawdust heats up by activating the natural wood binders; this way the pellet maintains its shape even without adding articial

substances.

Wood pellet density varies based on the type of wood and can exceed that of natural wood by 1.5 - 2 times.

The cylinders have a diameter of 6 mm and a variable length between 10 and 40 mm.

Their density is equal to approximately 650 kg/m3. Due to their low water content (< 10%) they have a high energy content.

The UNI EN ISO 17225-2:2014 standard (that replaces the EN PLUS standard) denes pellet quality by specifying three classes: A1,

A2 and B. Maintain fuels and other ammables at a suitable distance.

Ravelli recommends using wood pellet classied A1 and A2 according to the EN ISO 17225-2:2014 standard, or certied DIN PLUS

(more restrictive than the A1 class) or ONORM M 7135. Pellet may be light or dark coloured, it is normally bagged into bags that show

the name of the producer, the main characteristics and classication according to standards.

📌Only use certified pellets. Poor-quality pellets can increase the rate at which dirt builds up on the glass and increase

maintenance work.

📌Using fuel that is not compliant with the above will void the warranty.

Ravelli pellet stoves of the Flexi 11 family are home heating appliances powered by wood pellets with automatic loading. They are

suitable for use as a secondary heating system or as a support for the main heating system.

The heat generated by pellet combustion is diused in the installation room by radiation and natural convection. It is possible to

choose whether to activate the front fan or keep the stove in operation by natural convection. In addition, in the Flexi 11 versions it

is possible to activate the ducting to heat another room, subject to activation by the installer.

The stove is controlled by an electronic control unit that manages the start-up, operation and shutdown phases and also includes

many other functions for control, programming and safety.

The user can choose the operating power from 5 levels, or set the temperature to be maintained in the room. In this case the stove

will manage the power to ensure maximum comfort. Among the functions of the electronic control unit there is also that of being

able to program the start-up and shutdown of the stove, setting the weekly chronothermostat.

All this can be done comfortably from the sofa using the handheld remote control.

Ravelli’s patented cleaning system minimises maintenance by the user. There is no longer any need to clean the brazier before

each lighting and all maintenance operations.

This stove has been designed for hermetic installations, so it can be installed in the traditional way, or by taking air directly from

outside.

Automatic cleaning system

The stove is equipped with atuomatic brazier cleaning system. This means that there is no need to carry out daily manual cleaning of the

brazier or every time the stove is lit. The automatic cleaning system is activated every time the stove is lit and after 6 hours of continuous

operation. The cleaning cycle, which involves shutting down, automatic cleaning and restarting the stove, takes about 10 minutes. During

this period the heating is guaranteed by the heat accumulated by the appliance itself.

Note: the times indicated are those set by default by the Manufacturer.

Recharge the fuel

Use only wood pellets, the characteristics shown in this manual.

During pellet loading prevent the pellet bag from coming into contact with hot surfaces.

📌It is not recommended to empty the pellet bag directly into the hopper to avoid depositing wood sawdust on the bottom of

the hopper.

To load the pellets inside the hopper, proceed as described below:

Step Action

1 Open the pellet hopper cover

2 Lift the slide

3 Pour the pellets into the hopper

4 Close the pellet hopper cover

Doors opening

The combustion chamber door, the pellet hopper lid and the ash drawer can only be opened when the stove is in the OFF state.

If one of them is not closed, the pellet supply is interrupted, the control unit emits an acoustic warning signal, while the symbol appears on

the display:

In this condition, by touching the CONFIRM button you can read the detail of the warning: “doors and ash pan open”. If the combustion

chamber door, the pellet hopper lid and / or the ash drawer are not closed within 1 minute, the stove switches off signaling ALARM 07.

Opening the doors also interrupts the automatic cleaning phase of the brazier. In the event of a prolonged interruption of the cleaning

phase, ALARM 19 may appear.

Remember that in the presence of an alarm the stove will have to be restarted manually.

User training

Once installation is complete, the user must always be fully trained in the functions and characteristics of the stove by the technician au-

thorized by Ravelli to ensure optimal and safe use.

The training should cover the following topics:

• Description of the stove, its operation and basic settings

• How to turn the stove on and off safely

• Fuel storage and refilling

• What to do in the event of an alarm, in particular that of “no ignition”

• How to clean the stove correctly and the importance of performing it on a regular basis

• It is advisable to schedule the first annual maintenance
