3.1 Responsibility

Ravelli declines all responsibility, both civil and criminal, with the

delivery of this manual, for any accidents deriving from partial or total

failure to observe the instructions it contains,

Ravelli declines all responsibility deriving from the improper use

of the stove, from its incorrect use by the user, by unauthorized

modifications and/or repairs or from the use of spare parts which

are not original.

The manufacturer declines all direct civil or criminal responsibility due to:

•

poor maintenance

•

failure to observe the instructions in the manual

•

use not compliant with the safety instructions

•

installation that is not compliant with the regulations in force in the

country.

•

installation by personnel who are not qualified or authorized

•

modifications and repairs that are not authorized by the manufacturer

•

use of spare parts that are not original

•

exceptional events

3.2 Spare parts

Use original spare parts only. Do not wait for the components to be

worn before replacing them. Replace a worn component before it is

completely broken to prevent any accidents caused by the sudden

breakage of components, perform the periodic maintenance checks

as described in the dedicated chapter.

3.3. The ceramic tile finishes (if any)

The cast majolica stoves with a special hand finish may cause

surface imperfections such as shadowing and details that make every

majolica one of its kind. As it is a delicate material, please handle with

care whilst cleaning and avoid blows as sudden breakage may occur.

Please also take care when loading the hopper (Ed.’s note; tank containing

the pellets) with the sack of pellets: do not place it on the stove!

3.4. What are the wood pellets

The wood pellets are made from sawdust and wood shavings produced

in joiners’ shops. The material used cannot contain any foreign

substance such as glue, varnish or synthetic substances.

Subjecting it to high pressure, the wood is pressed through a plate with

holes and due to the high pressure the sawdust is heated activating

the natural binders of the wood. Thus, the pellets keep their shape

even without the addition of bonding substances. The density of the

wood pellet varies according to the type of wood and can be 1.5 –

twice greater than that of natural wood. The diameter of the cylindrical

rods is 6-10 mm and their length can vary between 10 and 50 mm.

Their weight is equal to about 650 kg/m. Due to the low content of

water (8-10%) they have a high energy content.

The standards DIN 51731 define the quality of the pellets:

Length: 10-30 mm approx. Residual humidity: 6-12% approx.

Diameter: 6 – 10 mm approx. Ashes: <1.5%

Real weight: 650 kg/m

approx. Specific weight: >1.0 kg/dm

Calorific power: 4.9 kWh/kg approx.

Do not put the

bag of pellets on

the ceramic parts

during the loading

operations.

The pellets must be transported and stored in a dry place. They swell

on contact with damp, and cannot be used, They must always be

protected from the damp both during transport and in storage.

Ravelli recommends using a pellet with a diameter of 6 mm for

the stove. Otherwise it will be necessary to ask the assistance

centre for the appropriate regulations.

3.5. The components of the stove

This drawing shows the internal parts of a pellet stove.

By filling the tank (7), the pellets are loaded into the fire pot (3)

through the loading screw (1).

Ignition is by means of the resistance (2), which overheats the air

from the special entrance (5) which on contact with the pellets will

allow the development of the flame. At this point the exhaust smoke

is deviated towards the stainless steel exchanger (6) and through

the smoke extraction tube (4) it is released into the flue, through the

connection with the smoke exhaust pipe. (9).

4. SAFETY DEVICES

The oven is fitted with sophisticated safety systems so that, in the

case of breakage of one of the individual parts or defects in the flue,

no damage will be caused to the stove and the room in which it is

installed. In any case, when a problem arises, the pellets stop falling

immediately and the switch off phase is activated.

The corresponding alarm will be shown on the display. The details

can be seen in the chapter on the alarms.
