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.

📌 Pellets must be transported and stored in a dry area. Upon contact with humidity they swell and become unusable

📌 It is therefore necessary to protect them from humidity, both during transport and during storage.

Non-permitted fuels

We recommend not using the following materials as fuel:

• wood

• treated wood (painted, lacquered, glued wood etc.);

• sawdust or chips

• liquid fuel

• coal or other fossil fuels

• plastic and derivatives

• treated paper and cardboard

• waste

• fuels that release toxic or polluting substances

Using these fuels, on top of being forbidden due to the emission of polluting and harmful substances, causes the stove to deteriorate

more rapidly and debris to accumulate in the stove and in the smoke evacuation system, thereby reducing performance and safety.

📌The gases produced by these fuels are dangerous for the environment and for your health!

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

Use and maintenance manual Touch Radio Hydro

Pag.12

Rev.2 06/04/2021

Automatic cleaning system

The stove is equipped with automatic 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.

Doors opening

The combustion chamber door 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 ap-

pears 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 combus-

tion chamber door and / or the ash drawer are not closed within 1 minute, the stove switches off signalling 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

authorized 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

Safety devices

The stove has been designed and equipped with safety systems to minimize user risks.

It is equipped with the safety devices listed in the following table, which also intervene in case of failure of the electronic board.

Element Description

Water temperature thermostat If the water temperature exceeds the set safety value, it immediately stops the pellet load-

ing motor and the stove is automatically switched off; to restart it, it is necessary to wait

until it has cooled down and manually reset the thermostat, using the appropriate button.

Pressure switch If the pressure in the smoke outlet duct is too high (a sign that the smoke evacuation sys-

tem is obstructed) it immediately stops the pellet loading motor and the stove switches off

automatically.

Limit switch for closing combustion

chamber door, ash drawer and pellet

hopper lid

If the door of the combustion chamber, the ash drawer or the pellet hopper lid are not

properly closed, it immediately stops the pellet loading motor; if they are not closed within

60 seconds, the stove switches off automatically.

Safety valve for water overpressure In the event of overpressure of the hydraulic system, the safety valve opens discharging

water, so that the stove is not damaged.

Electrical safety In case of failure of the electrical components or wiring, the fuse and grounding keep the

appliance safe. It is necessary that the electrical system of the house is up to standard,

equipped with a grounding circuit and all the safety systems required by the standards.

It should be noted that the stove’s operating program has been designed to stop stove operation in the event of malfunctions:

Anomalies Description

Temperature in the combustion cham-

ber

If the temperature probe in the combustion chamber detects temperatures that are too

high or too low, the stove is switched off and the relative alarm is displayed.

Flue gas temperature If the temperature probe at the smoke outlet detects temperatures that are too high, the

stove is switched o and the relative alarm is displayed.

Water over-temperature If the water temperature in the boiler of the stove, detected by the appropriate probe, is too

high, the stove is switched off and the relative alarm is displayed.

Water pressure If the water pressure in the boiler of the stove, detected by the pressure transducer, is too

high or too low, the stove is switched off and the relative alarm is displayed.

Smoke fan break If the fan stops, the electronic board blocks the supply of pellets and the alarm is displayed.

Gear motor failure If the gear motor stops, the appliance switches off safely.

Temporary power failure If a power failure occurs during operation, when the power returns the temperature in the

combustion chamber is checked and, if necessary, the stove goes into cooling mode.

No ignition If no ame develops during the ignition phase, the stove goes into alarm.

It is forbidden to tamper with the safety devices. Restarting the product is only possible after eliminating the cause that

caused the intervention of the safety system. To understand which anomaly occurs, consult this manual which explains,

depending on the alarm message that the device displays, how to intervene on it.

If the problem persists, contact the Support Service.

SHIPPING AND INSTALLATION

Safety warnings for transportation and installation

📌The stove must be installed by a qualied technician, who must issue a declaration of conformity of the system to the

purchaser, taking full responsibility for stove installation and correct operation.

📌The stove installation site must be chosen so that the generated heat can spread evenly throughout the rooms that you wish

to heat.

The stove needs to be connected to a single chimney that guarantees the draught declared by the Manufacturer and

observes the installation regulations that apply to the installation site.

The room where the stove is installed must have an air intake.

The air vent must be installed in such a way that it can not be blocked.

The Manufacturer will not be held liable for installation that is not compliant with the laws in force, incorrect air circulation in the rooms

and inappropriate use of the appliance.

In particular, it is necessary:

• that the appliance be connected to a smoke evacuation system duly sized to guarantee the draught declared by the Manufacturer,

that is tight and observes the distances from ammable materials;

• that there is a suitable combustion air intake in compliance with the type of installed product;

• that other installed combustion appliances or devices do not create a vacuum in the room where the stove is installed;

• that the safety distances from ammable materials are observed.

Verication of system compatibility has a priority over any other assembly or installation operation.

📌Local administrative regulations and particular requirements of the authorities pertaining to the installation of combustion

appliances, the air intake and the smoke evacuation system, may vary based on region or nation. Check with your local

authorities if there are stricter laws than set forth herein.

Set-ups for the smoke evacuation system

📌Be careful when building the smoke evacuation system and observe the regulations in force in the country where the stove

is installed.

The Manufacturer will not be held liable for incorrectly sized and non-regulation smoke evacuation systems.

Smoke ducts and ttings

The term smoke duct indicates all ducts that connect the combustion equipment to the chimney.

The following requirements need to be applied:

• observe product standard EN 1856-2;

• the horizontal sections must have a minimum slope of 3% upwards;

• the length of the horizontal section must be as minimum as possible, and its projection on the horizontal plane must not exceed

2 metres;

• changes in direction must not have an angle of more than 90° (45° bends are recommended);

• the number of direction changes, including the one necessary for insertion into the chimney, must not exceed 3;

• the cross section must have a constant diameter, the same from where it exits the rebox up to the tting into the chimney;

• it is forbidden to use exible metal and bre cement pipes;

• smoke ducts must not cross rooms where the installation of combustion equipment is prohibited.

In any case, the smoke ducts must be sealed against combustion products and condensation, as well as insulated if they lead outside

of the installation room.

Installing manual draught adjustment devices is not allowed.

Chimney

The chimney is a particularly important element for correct stove operation.

The chimney must be sized so as to guarantee the draught declared by the Manufacturer.

Do not connect the stove to a collective chimney.

The chimney must be built applying the following regulations:

• it must observe product standard EN 1856-1;

• it must be made of materials that are suitable to guarantee resistance against normal mechanical, chemical and thermal stress

and be correctly thermally insulated to limit the formation of condensation;

• it must be mainly vertical and not feature any bottlenecks along its entire length;

• it must be correctly spaced with an air gap and insulated from ammable materials;

• there must be a maximum of 2 changes in direction and angles must not exceed 45°;

• the chimney inside the home, however, must be insulated and can be inserted into a skylight shaft, as long as it respects

standards regarding placing inside a tube;

• the smoke conduit must be connected to the chimney using a “T” tting with an inspection collection chamber for combustion

residue and especially for collecting condensation.

📌It is necessary to check the safety distances that need to be observed when there are flammable materials and the type of

insulating material that needs to be used is on the chimney data plate.

Use watertight pipes with silicone seals.

It is forbidden to use the discharge mounted directly on the wall or directed towards indoor spaces and any other type of

discharge that is not set forth by the regulation in force in the country of installation (Note: in Italy only roof-discharge is

allowed).

Rev.2 06/04/2021

Installation

For appliance installation and use it is necessary to observe all of the local, national and European laws and regulations.

Stove installation and the preparation of the building work must observe the regulation in force in the country of installation

(ITALY = UNI 10683).

📌The installation activities must be carried out by a technician that is qualified and/or authorised by the Manufacturer. The staff

in charge of installation must issue a declaration of conformity of the system to the buyer, whereby they take full responsibility

for the final installation and good operation of the installed product.

📌Ravelli shall not be held liable if these precautions are not followed.

Requirements for the installation premises

The stove installation room must be suciently ventilated. To full this requisite it is necessary to equip the room with an air intake

connected to the outdoors.

📌The installation room must have an air intake with a free cross-section of at least 80 cm2.

📌For installation in the presence of other combustion appliances or VMC system it is necessary to check the appliance for

correct operation.

The stove must be placed inside living quarters. It must never be installed outdoors. The volume of the room where it is installed

must be suitable for the power of the appliance and, in any case, greater than 15 m3.

When extraction fans (example: extraction hoods) are used in the same room or space as the stove, this can cause problems

to stove operation.

The stove must be installed on a floor with suitable load capacity. If the existing position does not fulfil this requirement, it is

necessary to take due measures (for example, using a load distribution plate).

Provide due insulation if the surface is made of flammable material.

If the side walls adjacent to the stove are made of a ammable material, it will be necessary to position the stove at least 30 cm from

them.

If the oor that the stove is standing on is ammable, we recommend duly insulating it. Objects and parts that are heat-sensitive

or ammable cannot be stored near the stove;in any case, keep such objects outside the area bounded by the minimum distances

indicated above.

Stove installation must guarantee easy access to clean the appliance, the exhaust ducts and the chimney.

Rev.2 06/04/2021

This type of installation (See Fig.1) requires an insulated chimney

pot, even if the entire conduit is installed inside the building.

Besides, the structure must be inserted into a properly ventilated

skylight shaft.

In the lower part of the chimney pot there is an inspection cover,

properly isolated from wind and rain.

It is possible to use an existing chimney or a shaft via ducting. For

this type of installation the standards on ducted smoke evacuation

systems must be complied with. In the lower part of the chimney

pot, inside the home, there is a "T" type tting installed; externally

there is another one installed, so that the outside section can be

inspected.

It is prohibited to install two 90° bend, since the ashes would

quickly obstruct smoke passage, causing draught problems in the

stove. (See Fig. 2)

Electrical connection

The plug of the stove’s power cable must only be connected after the installation and assembly has been completed of the

appliance, and must remain accessible after installation.

To make the electrical connection, proceed as described below:

First connect the power cable to the plug on the back of the stove and then to a wall socket.

Supply power to the stove by turning the switch to position (I).

📌When the stove is not in use, it is advisable to disconnect the power cable.

Take care that the power cord (and any other cables outside the equipment) do not come into contact with hot surfaces.

Ensure that the electrical system is grounded.

For direct connection to the mains, it is necessary to provide a device that ensures disconnection from the mains, with a

contact opening distance that allows complete disconnection under the conditions of over-voltage category III, in accordance

with installation rules

If the power supply cable is damaged, it must be replaced by the manufacturer or its technical assistance service or in any

case by a person with similar qualifications, so as to prevent any risk.

It is recommended that authorized personnel pay special attention to the electrical connections after any work on the product.

Connection of external probe or thermostat

To manage the ducting in automatic mode, connect a temperature probe (optional) or external thermostat (optional) to the connector.

📌Connect an open/closed external thermostat, therefore potential-free.

📌If you wish to detect the ambient temperature by means of an external thermostat (optional), this must be connected to

the appropriate connector on the rear side of the stove; and you will have to activate the reading in “SETTINGS - ENABLE

THERMOSTAT.” On display appears the writing TON / TOFF based on thermostat request.

Connect an external thermostat with a simple dry contact, therefore, not powered, moreover, we recommend you use a

thermostat with a minimum offset of 3°C if you intend to use the “comfort clima” function.

Testing and commissioning

Stove start-up must be preceded by testing, which includes an operational check of the following elements:

• connection to the smoke evacuation system;

• electrical connections;

• hydraulic connections;

• operation of any connected external probes;

• checking that all materials used to build the smoke duct, chimney and chimney pot are regulation and suitable for use.

The testing is positive only when all operational phases have been completed without any anomaly being detected.
