OUR STOVES ARE TESTED TO DIN EN 13240. THE DECLARATION
OF PERFORMANCE MAY BE VIEWED AND IS OBTAINABLE FROM
WWW.SPARTHERM.COM
These stoves have a self-closing firebox door, and so the door is only ever
opened for operating purposes (e.g. cleaning the firebox or putting on more
wood). For safety reasons, tampering with the closing mechanism is not
permissible and will void the warranty and the operating permit. The war-
ranty and the operating permit will also be rendered void if the customer
makes any technical modifications to other parts of the stove.

1. GENERAL INFORMATION
Before your stove is assembled and installed you should meet with the mas-
ter chimney sweep responsible for such matters in your area. He will advise
you on the building regulations and suitability of your chimney and will carry
out the acceptance test on your stove. Calculation of the dimensions of the
chimney is based on DIN EN 13384 using the set of measured values given
in this manual („9. Technical data“ on page 40).
Important for young children, the elderly or the frail: As with all other heating
appliances, a guard should be fitted to protect the above persons because
both the glass door and the stove cover panels can become very hot in use.
Risk of burns!
Never leave a stove unsupervised when it is lit or when the fire has just
gone out. As a basic rule, the stove should not be left unattended for long
periods of time when lit.
The protective glove supplied is designed only for protection
from heat when operating the control handle and the cold
hand. The glove is not fireproof.
When installing and operating your stove and when connecting it to the
chimney you must ensure that you comply with national and European
standards, the relevant country-specific and local guidelines and regula-
tions and, in Germany, the relevant Heating Regulation (FeuVO) of the state
where you live.
The stove should always be operated with the door closed. Modify-
ing the closing system is not permissible.
*Caution: The protective glove supplied is designed only for protection from
heat. It is not fireproof.

1.1.2 DAMAGE IN TRANSIT
Please inspect the goods immediately upon delivery (visual inspection).
Any damage should be noted on your delivery note. You should then inform
your stove fitter. Protect the visible parts of the stove from dirt and dam-
age during installation. Only approved and sufficiently strong handling aids
should be used to transport your stove.
The following points must be noted to ensure safe transport without any
problems:
• The stove should always be transported in the upright position or tilted
slightly backwards.
• Hand trucks used as handling aids must load the stove from the rear
only.
2. INSTALLATION INSTRUCTIONS
The assembly and installation of your stove should be carried out
by a specialist. Before your stove is assembled and installed you
should meet with the master chimney sweep responsible for such
matters in your area to discuss the suitability of your chimney and
the installation location and to clarify any other matters.
2.1 GENERAL REQUIREMENTS FOR INSTALLATION
All relevant national and European standards and local regulations
(DIN, DIN EN, state building regulations, heating system regula-
tions, etc.) must be noted and observed when installing, connecting
up and operating the stove. Selected relevant regulations are listed
below. This list does not claim to be complete.

Fireplaces should only be installed in rooms and at locations where the
position, structural conditions and type of use will not create any hazards.
The floor area of the room where the fireplace is installed must be of such
a type and size that it can be correctly operated in accordance with the
instructions.

GB 6
2.2. ASSEMBLY / INSTALLATION
The floor on which your stove is installed must have sufficient load-bearing
capacity. Please note the overall weight (refer to section „9. Technical data“
on page 40). If necessary, load-bearing capacity must be ensured by
placing the stove on top of a slab of sufficient thickness for weight distribu-
tion purposes.
When selecting the installation location please also note the necessary fire
precautions with regard to the floor. („2.2.3 Fire Precautions“ on page 10).
Stability
Tall stoves with storage stones on top are top-heavy and must be secured
against accidental toppling.
Appropriate measures may therefore need to be taken to ensure the stability
of the CUBO/PIKO M models. SPARTHERM can supply an optional stability
aid which enables the stove to be securely fastened to the floor on which
it is installed. This is available for the PIKO/CUBO ranges under part no.
1018625 (rotatable) / 1018626 (non-rotatable).
Stand the stove on the floor and level it horizontally, observing the safety
distances (refer to section „2.2.3 Fire Precautions“ on page 10). The legs
are height-adjustable.
2.2.1 CHANGING THE DIRECTION OF THE FLUE GAS
CONNECTION
The stove is supplied ready for use with a top flue gas connection. Alterna-
tively, a rear, side or corner flue connection is possible, depending on the
model. To change the flue connection position, the following steps should
be carried out:
2.1.1 INSTALLATION LOCATION
Your stove must not be installed:
1. In stairwells and landings, except in residential buildings with no more
than two flats.
2. In corridors accessible to the public
3. In garages.
4. In rooms or flats that are vented by ventilating systems or hot air sys-
tems using blowers, unless the safe operation of the stove is ensured.
5. In rooms where highly flammable or explosive substances or mixtures
are processed, stored or manufactured in such quantities that ignition or
explosion would be hazardous.
Room air sealed stoves may be installed in rooms, flats or units of com-
parable size from which air is extracted with the aid of blowers, such as
ventilation systems or hot air heating systems, provided that the negative
pressure generated by this equipment does not exceed 8 Pa.
2.1.2 MULTIPLE USAGE
Multiple usage of the chimney in accordance with DIN 18160 is possible
as the stove has a self-closing firebox door (A1). Note that all fireplaces
connected to the same chimney must also be approved for multiple usage.
In the case of room air sealed stoves:
Multiple usage of the chimney is not permissible.

GB 7
Changing the flue gas connection direction from top to rear, taking
the Senso S as an example
Changing installation from top to rear
Carefully remove the top plate (A) (Fig. 1) from the stove and set it aside in a
safe place. When removing the top plate take care that the blanking plate on
top (B) (Fig. 1) does not fall off and get damaged. Depending on the model,
the stove plate can either be raised and lifted off, or it may first have to be
released by sliding it forward, keeping it level (Stovo model range).
In the case of units with storage stones on top (e.g. CUBO/PIKO M (Fig. 2)
or a convection air controller (Fig. 3) these components should be removed.
(„2.2.7 Fitting the Storage Stones – Passo M“ on page 14).
Once the top plate has been removed, the flue gas pipe connection (C)
screwed on to the stove body (Fig. 4) is visible. Undo the hexagon head bolts
on the inside to remove it (13 mm spanner). Now remove the blanking plate
(D) (Fig. 5) on the rear cover panel to allow the flue pipe to pass through.
To do this, either break out the perforations or undo two fastening screws,
depending on the model.
The blanking plate which is now visible (E) (Fig. 6) must be removed by
undoing the bolts on the inside (13 mm spanner) and replaced by the flue
gas connection (C) removed previously (Fig. 4). Fit the blanking plate which
you removed (E) to the top flue gas outlet to seal it off. (Fig. 7) (bolts, 13
mm spanner)
Make sure that the seals are correctly positioned underneath the blanking
plate and the flue gas connection and that they make a tight seal. After fit-
ting the blanking plate, install the optional storage elements and convection
air regulator in reverse order and place the cover panels in position. (Fig. 8)
Note: The assembly sequence may vary according to the stove model.
Special note re the PIKO H20 model
As well as a side and top flue gas outlet, the PIKO H20 model also offers the
option of a corner flue gas connection. If the installation position of the PIKO
H2O stove is already known at the planning stage, the stove can be ordered
with the flue gas connection fitted accordingly from the factory. In order to
alter the position of the flue gas connection on site, proceed as follows:
Changing installation from top to rear or side
The flue gas pipe can be connected at the rear in three different positions.

Carefully remove the top plate (A) (Fig. 9) from the stove and set it aside in
a safe place. When removing the top plate take care that the blanking plate
on top (B) (Fig. 10) does not fall off and get damaged.
Once the top plate has been removed, the flue gas pipe connection (C)
screwed on to the stove body (Fig. 10) is visible. Undo the hexagon head
bolts on the inside to remove it (13 mm spanner). Now remove the rear cover
plate (D) (Fig. 10) by undoing the screws. After removing the cover plate,
a blind connection for the flue gas outlet can be seen at the rear/side. (E)
(Fig. 11) Undo it.
Now fit the flue gas pipe connection in the desired position, either at the
right/left side or in the rear centre. A separate pipe connection is packed
with the stove for use if making a right/left side connection (Fig. 13). The
top pipe connection is used if making a rear connection. Make sure that the
cord seal underneath is correctly positioned and that it makes a tight seal.
The blanking plate which was previously removed (E) should be screwed on
as shown in Fig. 12 to seal off the top flue gas outlet.
Finally, close the open sections of cover panel at the rear of the stove using
the cover plates supplied, and place the top plate in position (Fig. 14).
2.2.2 COMBUSTION AIR SUPPLY
The combustion air supply can be provided in one of two ways, either ‘room
air dependent’ as described in section „2.2.2.1 Room Air Dependent“ on
page 8 or ‘room air sealed’ as described in section „2.2.2.3 Room Air
Sealed“ on page 9.
2.2.2.1 ROOM AIR DEPENDENT
Your stove takes the air it needs for combustion from the room where it is
installed (room air dependent operation). An adequate supply of fresh air
must be ensured in the room where the stove is installed (for further details
refer to the heating systems regulations for the country concerned, DIN
18896, the technical rules, etc.) The installer and the operator of the stove
should check the fresh air supply. An adequate air supply for combustion
must be ensured when several fireplaces are operated in one room or in
adjoining rooms. If the windows and doors are sealed (for example, for

energy-saving reasons) it may be the case that an adequate fresh air supply
cannot be guaranteed. The stove draught may be adversely affected. This
can be detrimental to your health and also, in some cases, to your safety. If
necessary, an additional air supply should be provided by fitting an air inlet
near the stove or by fitting a combustion air intake pipe which connects
with the external air (see „2.2.2.2 Separate Combustion Air Supply“ on
page 9) or with a well ventilated room (not the room where the stove
is installed). In particular, it must always be ensured that the necessary
combustion air intakes remain operational when the fireplace is in use.
Operating a ventilating system at the same time, e.g. an extractor hood or
bathroom fan, in the same room or in an adjoining room can adversely affect
the operation of the stove (even causing smoke or flue gas to leak out into
the room, despite the firebox door being closed). Ventilating devices must
therefore not be operated at the same time as the stove unless suitable
measures are taken to maintain the air supply to the stove. („2.2.2.3 Room
Air Sealed“ on page 9).
2.2.2.2 SEPARATE COMBUSTION AIR SUPPLY
It is possible to provide the stove with a separate combustion air supply.
The separate combustion air connection can be connected to the rear of the
unit or to the bottom of the unit. The connecting piece is pre-assembled and
the cover panels should be opened up as necessary. If a pipe connection is
attached to the combustion air coupling, the combustion air can be drawn
into the stove from outside or from other rooms such as the basement. When
connecting the stove to a combustion air pipe, the requirements of TROL
(technical rules), DIN 18896, etc. should be observed and applied.
In particular, care should be taken that the dimensions of the pipes
are adequate. If using a swivel connector, a permanently flexible
connection must be made. The rotating action must not be restricted.
Combustion air intakes and pipes must not be obstructed or closed unless special
safety devices are fitted to ensure that the stove can only be operated when the
closing system is open. The cross-section must not be reduced by means of an
obstructor or grille. This measure is not necessary with balanced flue systems.
If the combustion air pipe has to be routed out of the building, a shut-off device
must be fitted. The position of the shut-off device must be obvious from the out-
side of the connecting pipe. In this design version the pipe should be insulated,
as condensate may form. Also, when fitting the pipe it should be ensured that
no water or other substances can enter the stove and that any condensate can
drain away. According to the relevant provisions, combustion air ducts that bridge
firewalls in buildings with more than two full storeys must be constructed such
that fire and smoke cannot spread to other storeys or fire lobbies. The national
and local fire precautions for the place of installation must be observed.
2.2.2.3 ROOM AIR SEALED
Room air sealed stoves have been developed for use in conjunction with home
ventilation systems for a negative pressure range of up to 8 Pa in the room where
the stove is installed and can be operated without any additional safety precau-
tions. In room air sealed operation, the air supply for combustion must be led into
the unit from an external source via airtight pipes, or via a balanced flue system.
The combustion air duct must be permanently sealed tightly to the combustion air
connecting piece (rear / side or bottom connection) on the stove.
When connecting a room air sealed stove to the combustion air pipe, the require-
ments of TROL (technical rules), DIN 18896, etc. should be observed and applied.
In particular, ensure the dimensions are adequate.
The national and local fire precautions for the place of installation must be
observed. Please ensure that the pipework is permanently leaktight.

GB 10
2.2.3 FIRE PRECAUTIONS
General Information about Fire Precautions
Stoves generate heat and are subject to regulations and essential fire pre-
cautions. The fire precautions and minimum distances should be borne in
mind when selecting the installation location for the stove. A minimum
distance of 5 cm from the rear wall must always be maintained.
Greater distances should be allowed for reasons of safety and fire
prevention in the case of walls that need to be protected or combus-
tible building components.
The table that follows (see page 12) shows the distances that must be
maintained according to the type of stove and the nature of the walls on
site. Use the drawings (Figs. 17-21) to help you determine your particular
installation situation and note the distances that must be maintained.
Note the fire precautions when installing the stove. Ask your local
chimney sweep for advice.
• Their structure and materials enable mounting walls that are not com-
bustible and not in need of protection to be permanently exposed to
temperatures above 85°C.
• Mounting walls that are combustible or need to be protected (e.g.
stud partition construction) must be protected from temperatures above
85°C.
The mounting walls should be assessed before installing the stove. If the
nature of the mounting wall cannot be identified with certainty, a specialist
(such as the chimney sweep) should be consulted.
• According to DIN 4102-1, wallpaper used as a wall covering is not
considered a combustible building component and does not require
any special fire precautions. Please bear in mind that the structure
underneath the wallpaper (e.g. stud partition construction) may very
possibly be combustible or in need of protection, and appropriate pre-
cautions should be taken.
• Please note that the minimum distances indicated from rear wall and
side walls need to be adapted for rotating stoves.
• It is important to observe the minimum distance from the chimney
connecting piece to combustible building components (refer to section
„2.2.5 Connecting Piece“ on page 14).
• There must be no combustible objects within a radius of 50 cm above
the fireplace.
Floor coverings near the stove
Floors made from combustible materials in front of the firebox door must be
protected by a covering of non-combustible materials. The covering should
extend at least 50 cm in front of the stove and at least 30 cm at each side
(Figs. 17-21 C+D) (measured from the firebox door or viewing pane).
There must be no combustible building components, furniture, curtains or
decorations within the radiant area of the firebox door or viewing pane. That
distance can be reduced to 400 mm if a fire screen ventilated on both sides
is placed between the fireplace and any combustible objects.
Minimum distances from nearby building components
The distances indicated in the table (see page 12) must be observed,
according to your stove’s window arrangement (see sketches below) and the
nature of the mounting walls.
Here,
• Distance A is the minimum distance from the side wall of the stove to
the mounting wall
• Distance B is the minimum distance from the rear wall of the stove to
the mounting wall
• Distance C is the radiant area in front of the stove window(s).
