1.4 Permissible and non-permissible fuels
Permissible fuels are natural-type logs of wood, dry and resin-free (beech, oak and birch), 20-25 cm long. The
wood should be seasoned for at least two years; the maximum recommended moisture content is 20%, in order
to ensure combustion without smoke and soot.
Do not use:
-coal dust;
-wood cut into thin pieces (only permitted as kindling);
-bark and chips;
-waste in general;
-treated cardboard and paper;
-wood treated with protective substances.
The burning of waste is prohibited according to European and national laws.
Burnt gases produced by the combustion of unsuitable materials can damage the stove and flue, and
compromise your health.
The use of any fuel not complying with that specified above
invalidates the warranty.
1.5 Accessories supplied

1.9 Stove decommissioning
For disposal, the stove must be sealed inside strong packing; contact the local authority in charge of such
operations in order to proceed according to the current local regulations.
2 – TRANSPORT AND INSTALLATION
2.1 Packing, handling, shipment and transport
The stove can be lifted using a lift truck, inserting the forks (of suitable length) in the special spaces in the wooden
packing.
Make sure the equipment used for lifting and transport can take the weight of the stove, specified on the dataplate
and in this manual.
Avoid taking the load in areas where it could be a danger if dropped.
Set the stove down on the floor carefully without bumping, and position it in the required place; make sure the
floor can take the weight of the stove, otherwise contact a specialised technician.
2.2 Instructions for safe installation
The stove must be installed by a technician, taking into account the local, national and European regulations. The
stove must be placed on a floor able to take its weight; otherwise corrective measures can be taken according to
the advice of specialised technicians.
Do not keep flammable or heat-sensitive parts near the glass. The minimum front distance for the protection of
flammable objects is 80 cm. Flammable or heat-sensitive parts must be at least 20 cm from the side and the
back wall. If the support base is made of flammable material (wood, cork, etc.) a protection base in 2-3 mm thick
steel plate or a sheet of toughened glass must be provided.
2.3 Connection to the flue
The stove must be connected to the flue with connection supports place on the top part of the stove body and by
means of flue pipes readily available on the market. Connection to the chimney must be made using strong and
stable pipes at least 1.2-2 mm thick. The flue pipe must possibly be straight, to avoid pressure losses, and
towards the flue. The single parts of the exhaust gas pipe must be tight.
To ensure regular operation, the flue draught with stove operating must be between 10 and 14 Pa.
For maximum stove efficiency, a draught control or
damper should be installed in the flue pipe or chimney.
Every unit must eliminate the fumes through its own flue; never use the same flue for several units.

2.4 Room ventilation
The air necessary for combustion, i.e. up to 20 m³ every hour, must be ensured in rooms where stoves with
natural flue draught are installed. The air change must occur through several fixed openings to the outside, whose
cross section must comply with the current local regulations. These openings must be protected with grilles and
must never be obstructed.
If the air is insufficient, even the operation of an extractor hood in the room or exhaust fans can negatively affect
stove operation.
2.5 Advice on flues and connections
Flues must be made from suitable materials and perfectly insulated, with characteristics that prevent temperature
decreases.
The inner walls must be perfectly smooth without any narrowing or protrusions along the entire length, so as not
to create friction or vortices in the smoke which could cause a considerable reduction in draught.
Any doors for cleaning and inspection must be perfectly closed during operation.
The flue outlets must be 0.5 m higher than any obstacles within a radius of 10 m and must end with chimney caps
or cowls having a useful outlet cross section of at least double that of the flue.
The following two figures give the data regarding the distances and positioning of chimney caps in conformity with
the provisions of UNI 10683/98.

Before connecting stove to an existing chimney, in addition to complying with that described above, make sure
there are no openings or cracks where air could enter and cause a temperature decrease affecting the draught.
Make sure there are no obstructions caused
by foreign bodies or a buildup of soot.
The first connection section leaving the stove
should be vertical, whereas the flue
connection to the chimney (which goes to the
chimney cap) must only enter by a few cm, so
as not to reduce the cross section of the
flue.

If the flue is not perpendicular to the chimney it is advisable to make the connection with special steel fittings that
allow a maximum slope of 45°.
If the walls and ceiling are made of flammable materials, the parts in contact with the flue must be suitably
insulated. All connection joints must be carefully sealed, in particular where the connection enters the flue.
If there are several heating stoves in the same home, each must have its own flue. It is inadvisable to make
openings in the flue for other appliances, since the draught could be negatively affected.
According to Standard UNI 7429, the chimney cap must meet several requirements; above all, it must have a
useful outlet cross section at least double that of the flue. It is also
advisable to install an "antiwind" cap that guarantees fume exhaust even
in the presence of strong horizontal winds.

3 – STOVE USE
3.1 Introduction
Never leave children unsupervised in the vicinity of the stove; the risk of burns caused by the hot parts is very
high. Carefully observe the following rules:
- never use the stove with the door open;
- do not keep firelighters or easily flammable materials near the stove;
- do not move or lift the stove using the handles.
3.2 Adjusting the combustion air
Primary air:
the primary air is adjusted using the manual revolving controls on the firebox door, and feeds the fire through the
grate.
Secondary air:
the secondary air enters the stove by means of the sliding control located above the firebox door.
Optimum combustion conditions exist when, on loading wood, the combustion air feeds the flame by entering
through the grille, whereas the secondary air, entering through the control, enables the completion of combustion
in the upper part of the firebox.
3.3 Start-up
With first start-up, bad odours may be created, therefore air the room thoroughly especially when lighting the
stove the first time.
When lighting the stove the first time, allow it to burn with a low flame for several hours (primary air control open
30%).
The heat can then be increased a little at a time, so that the stove expands slowly and the paint and putty dry.
3.4 Lighting and controlling the fire
To light the fire it is advisable to use kindling and newspaper, or other means available on the market (excluding
any solid or liquid flammable and/or explosive substance).
The air control on the door, in the ash zone, must be open and is for adjusting stove heat output after the lighting
stage.

8 Betty
3.5 Normal operation
Remove the ash from the grate each time before loading fuel. Put 2-3 logs of wood on the bed of embers for even
consumption and good efficiency.
Despite the large capacity of the combustion chamber, it is advisable to only load a max. of 2-3 logs at a time: the
hourly wood load for obtaining nominal heat output is given on the dataplate. Overloading does not increase
efficiency, but will overheat the stove, damaging it.
3.6 Operation with partial feed
Heat output can be controlled by reducing the combustion air. To guarantee operation for many hours at low heat,
the primary air control must only be opened at minimum.
With partial feed operation, a patina may form on the glass due to the low temperature in the fire zone. In any
case, a continuous fire with low output is not advisable.
3.6 Off-season operation
With outside temperatures above 15°C, the draught m ay be affected, resulting in a decrease in heat output and
therefore flue gases not completely exhausted (smell of smoke in the room). In this case it is advisable to remove
the ash from the grate and increase the combustion air. Put less fuel on the fire and clean the grate more
frequently.
3.7 Idle period
If the stove is not used for long periods it is advisable to store it in a safe and protected place.
To best preserve the stove:
-carefully clean it, and replace any damaged parts if necessary;
-cover it to protect from dust.
4 – ROUTINE STOVE CLEANING AND MAINTENANCE
Good maintenance will help improve stove operation, efficiency and service life.
Every day, before lighting the fire make sure to clean the grate of any unburnt residuals and remove the ash from
the ash pan zone.
4.1 Removing the ash
The stove has an ash pan and a removable grate which should be cleared of ash, using the poker supplied, every
time before loading fuel.
Make sure to periodically empty the ash pan, since the accumulation of ash under the grate hinders the flow of
combustion air. Otherwise the grate will overheat and may become damaged.
To prevent the risk of fire, allow the ashes to cool outdoors inside a metal container or in the stove and
eliminate them in compliance with current local regulations.
4.2 Cleaning the glass
The glass can be cleaned using a damp cloth and specific non-abrasive detergents.
Do not clean the glass during stove operation. The glass must only be cleaned when the stove is cold.
4.3 Cleaning the flue
A reduction in heat output is nearly always due to obstruction of the flue. Also, the presence of burnt gases with
odours can be a sign of an obstructed flue.
The flue of your stove must be cleaned at regular intervals. The amount of soot and the frequency of cleaning will
depend largely on the type of fuel and the type of use (low or high heat output).
To avoid unnecessary dust, carry out cleaning according to the following instructions:
-clean only when the stove is off;
-close all the openings that must not be cleaned;
-remove the flue pipe and clean it outdoors;
-remove the deposits inside the stove with a wire brush;
- all the residuals removed from the grate or the ash pan must be taken away;
- in any case detach the pipe from the chimney.
When refitting the pipes take care not to damage enamelled or painted parts and the seals.
Dispose of cleaning waste in accordance with the local regulations.

9 Betty
4.4 Cladding maintenance
Clean the cladding only when the stove is cold.
The ceramic tiles are handicraft production and therefore may have minor surface imperfections such as tiny
spots or slight colour differences.
It is advisable to use a soft dry cloth to clean the ceramic surfaces; the use of detergents could highlight any
flaws.
