To open the firebox door pull the handle outwards. A protective glove is supplied for opening the stove
firebox door (the handle becomes very hot).
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;
-thinly cut pieces of wood (permissible only in the lighting stage);
-bark and chips;
-waste in general;
-treated paper and cardboard;
-wood treated with protective substances.
The burning of waste is prohibited according to European and national laws.
The burnt gases produced by the combustion of unsuitable materials can cause damage to
the stove and flues, and compromise your health.
The use of any fuel not complying with that specified above invalidates the warranty.
1.5 Accessories supplied
The supply includes:
- operating instructions;
- poker;
- glove for hot handles.
1.6 Reference standards
Standard EN 13240 : European standard for solid fuel burning stoves, containing the technical
specifications for correct construction in terms of design, operation and safe use.

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 consult 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 support .
its weight; otherwise corrective measures can be taken by consulting specialised technicians.
Flammable parts or those sensitive to heat must not be kept near the glass, as this zone becomes hot.
The minimum front distance for the protection of flammable objects is 80 cm. The minimum side
distance and that of the rear wall from flammable parts or those sensitive to heat is 20 cm. 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.

8 Termo Regina 4
2.3 Connection to the flue
The Regina 4 stove must be connected to the flue with connection supports located at the top 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 of recommended minimum thickness of 1.5-2 mm. The
flue pipe must possibly be straight, to avoid pressure losses, and towards the flue. The individual parts
of the flue pipe must be sealed.
To ensure regular operation, the flue draught with stove operating must be between 10 and 14 Pa.
For optimum stove efficiency, a draught control or damper must be fitted in the flue pipe or chimney.
Every unit must eliminate the fumes through its own flue; never use the same flue for several units.

2.5 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. Such 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 can negatively affect stove
operation.
2.6 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 cleaning and inspection doors must be perfectly closed during operation.
The flue outlets must be 0.5 m higher than any obstacles located less than 10 m away 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 a heating 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.
Also make sure there are no hindrances caused by foreign bodies or a build-up 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.
Make sure to carefully observe the following rules:
- never use the stove with the door open;
- do not store firelighters or easily flammable materials near the stove
Fig. 3 Stove-chimney connection

11 Termo Regina 4
- do not move or lift the stove using the handle.
3.2 Startup
When lighting the stove the first time, bad odours may be created, therefore air the room thoroughly.
When lighting the stove the first time, allow it to burn with a low flame for several hours (air control on
ash door 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.
3.3 Lighting and controlling the fire
To light the fire, it is advisable to use small sticks of wood and newspaper, or other means available on
the market (excluding any solid or liquid flammable and/or explosive substance).
The air control on the ash door must be open, and is used for adjusting stove heat output after the
lighting stage.
3.4 Normal operation
Remove the ash from the grate every 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. Overloading does not increase efficiency, but will overheat the stove, damaging it.
3.5 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 Operation in off season
With outside temperatures above 15°C, the draught may 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 it 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, remove any unburnt residuals on the grate and the ashes in the ash
pan zone.
4.1 Removing the ash
The REGINA heating stove has an ash pan and 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.

12 Termo Regina 4
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 Cladding maintenance
Clean the cladding only when the stove is cold
COLA ceramics 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 imperfections
4.3 Cleaning the glass
The glass can be cleaned using a damp cloth and specific non-abrasive detergents.
Do not clean the glass when the stove is operating. The glass must only be cleaned when the
stove is cold.
4.4 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 flues 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 openings which are not to be cleaned;
-remove the flue pipe and clean 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 flue.
When fitting the pipes, make sure not to damage the enamelled or painted parts and the seals.
Dispose of cleaning waste in accordance with the current local regulations.
