These stoves are equipped with a self-closing fire door which means the
door is only opened when the fireplace has to be serviced (e.g. to clean
the combustion chamber or add more fuel). For safety reasons, the closing
mechanism must not be tampered with; furthermore, any such action would
render the warranty and operating licence null and void. The guarantee and
operating licence are also rendered invalid if the customer modified the
technology of any other area of the stove.

Attention! The transport and alignment aids may only be used on a stable
subfloor. Soft, delicate floors can be damaged by the high surface pressure
of the transport casters!
2.3 INSTALLATION/ASSEMBLY
Your stove must be installed on floors with sufficient load-bearing capacity.
Please observe the overall weight („9. Technical data“ on page 46)! The
load-bearing capacity may have to be ensured by a sufficiently thick board
(weight distribution).
Observe the necessary measures for fire protection in the floor area when
choosing the installation location. („2.3.3 Fire safety“ on page 14)
Stability "9. Technical data“ on page 6
Stoves with an upright design and fitted heat storage stones must be
secured against unintentional tilting because of their top-heaviness.
The stove is placed on the floor in compliance with the safety distances
(„2.3.3 Fire safety“ on page 14) and aligned horizontally. The feet are
adjustable in height.
Flue pipe elbow kit
Install the stove with the flue pipe bend set that we offer and refer to the
following for the stove-specific connection height dimensions.

would be hazardous in the event of ignition or explosion
Room air independent stoves can be placed in rooms, apartments or uti-
lization units of comparable size from which air can be sucked out using
fans such as ventilation or hot air heating systems. The condition is that the
vacuum-capable equipment cannot create a vacuum > 8 PA.
2.1.2 MULTIPLE CONFIGURATION
Multiple use of the chimney in accordance with DIN 18160 is possible
because the stove has a self-closing fire door (A1). All fireplaces connected
to a chimney must also be approved for multiple use!
The following applies to room-air-independent stoves:
A multiple chimney configuration is prohibited!
2.2 TRANSPORT AND ALIGNMENT AID
The Spartherm stoves Moro and Noto with integrated transport and align-
ment aid give you the possibility to move the stove to the installation loca-
tion with little effort and be able to perform the alignment quickly.
To do this, it is necessary to fully screw in the adjustable feet set into the
lower wood compartment to align the stove.
After screwing in the feet, the entire weight load of the stove is supported
by the transport casters set into the base. Now it is possible to move the
stove back and forth.
Please ensure that the fitted natural stone elements do not move or fall off
the stove! After positioning, unscrew the adjusting feet and ensure the stove
is standing securely.

Make sure that the sealing elements are correctly positioned under the
dummy cover and the flue gas outlet and ensure a tight seal. After screwing
in tight, fit the optional storage elements and convected air gate to prevent
airflow in reverse order and fit the lining elements (Fig. 8).
Note: The installation steps may be different depending on each stove model.
Special notes on the Piko H20 model
The Piko H20 model has gas evacuation to the side and to the top in addition
to the option of connecting the connecting piping around a corner. If the
installation situation of the Piko H2O stove has been decided already during
the planning phase, it is possible to order the stove with preassembled
matching flue gas outlet from the factory.
If the orientation of the flue gas outlet on site has to be changed, please
proceed as follows:
Installation from the top to the back/side
The flue gas outlet can be connected to the back in three different positions:
Carefully remove the top plate (A) (Fig. 9) of the stove and place it in a
protected place. When removing the top plate, ensure that the fitted dummy

2.3.1 CHANGING THE FLUE GAS CONNECTION
DIRECTION
The stove is prepared for the flue gas connection at the top when delivered.
Depending on the model, the flue gas connection position can be changed
so that it is aligned to the back, to the side or around corners. Follow these
installation steps when changing the flue gas connection position:
Changing the flue gas connection direction from to the top to the
back using the example of the Senso S
Installation from the top to the back
Remove the top plate (A) (Fig. 1) of the stove carefully and place it in a
protected place. When removing the top plate, ensure that the fitted dummy
cover (B) (Fig. 1) does not fall and gets damaged. Depending on the model,
the top plate of the stove must be removed either upwards in advance or
unlocked by parallel displacement to the front (model Stovo).
In stoves with fitted heat storage stones (for example, Cubo / Piko M (Fig.
2)) or convected air regulation (Fig. 3), these components must be removed
(„2.3.6 Installing the heat storage stones on top“ on page 18).
After removing the top plate, the flue gas connection piece (C) (Fig. 4)
bolted onto the stove body is visible. Remove these by loosening the internal
hexagonal bolts (SW 13). Now remove the dummy cover (D) (Fig. 5) on the
back of the covering panel for feed-through of the flue gas pipe. Depending
on the model, the perforation for this must be broken through or 2 fixing
screws loosened.
The only visible dummy cover (E) (Fig. 6) must be unscrewed using the
internal screws (SW13) and replaced with the previously removed flue gas
outlet (C) (Fig. 4). Fit the removed dummy cover (PE) onto the upper flue gas
outlet in order to close this (Fig. 7) (screw connection SW13).

GB
GB 9
After removing the top plate, the flue gas connection piece (C) (Fig. 10)
bolted onto the stove body is visible. Remove it by loosening the internal
hexagonal bolts (SW 13). Then, remove the back cover plate (Fig. 10) using
the screw connection. A blanking plug for the flue gas outlet to the back/
side is visible (E) (Fig. 11) behind the cover plate. Unscrew this.
Now fit the flue gas connection pipe depending on the desired orientation to
the right/left side or straight back. For the right/left side connection type, a
separate connecting piece is supplied with the Piko H20 stove (Fig. 13). The
top connecting piece is used for the back connection type. Ensure that the
underlying caulking strip is placed correctly and seals tightly.
The removed dummy cover (E) is screwed in place as shown in (Fig. 12) and
seals the flue gas outlet at the top.
Finally, close the open cladding openings at the back of the stove with the
enclosed cover plates and fit the top plate (Fig. 14).
2.3.2 COMBUSTION AIR SUPPLY
The combustion air can be supplied in accordance with „2.3.2.1
Room-air-dependent“ and „2.3.2.3 Room-air-independent“ in different
ways
.
2.3.2.1 ROOM-AIR-DEPENDENT
Your stove draws the combustion air from the installation area (room air depend-
ent operation). Ensure that the installation area is adequately supplied with
fresh air (more details in the country-specific FeuVO, DIN 18896, the technical
regulations, etc.). The fresh air supply must be checked by the installer and the
operator. When operating several fireplaces in a single room or linked space,
ensure that sufficient air is available for complete combustion! It is possible that
there is not a sufficient supply of fresh air if the windows and doors are sealed
(e.g., in combination with energy saving measures). As a result, the ventilation
of the tiled stove can be affected. This can adversely affect your well-being
and, potentially, your safety. If necessary, an air valve must be installed near
the pellet stove for the additional supply of fresh air, or a combustion air line
must be routed outwards („2.3.2.2 Separate combustion air supply“) or in a
well-ventilated room (except for the heating room). In particular, ensure that the

necessary combustion air pipes are open during the operation of the fireplace
insert. Simultaneous operation with a ventilation system (e.g. extractor hood,
bathroom fan, etc.) in the same room or connected space can adversely affect
the function of the stove (to the point of smoke or flue gas accumulating in the
living room, despite the firebox door being closed). It is therefore prohibited
to operate appliances of this kind simultaneously with a fireplace without first
taking appropriate precautionary measures („2.3.2.3 Room-air-independent“).
2.3.2.2 SEPARATE COMBUSTION AIR SUPPLY
The stove can be supplied with combustion air separately. The separate com-
bustion air connection can be connected to the rear side or from below. The
connecting piece is preassembled and the cladding must be opened accord-
ingly. When connecting a pipe connection to the combustion air neck, the
combustion air can be supplied to the stove from the outside or from other
rooms such as the cellar. When connecting the stove to a combustion air line,
the TROL instructions (technical rules), the DIN 18896, etc. must be observed
and applied.
In particular, ensure that the dimensions of the pipes are adequate!
When using the rotary base, the connection must be designed as
durable and flexible! The ability for it to rotate must not be affected.
The combustion air openings and lines must not be closed or blocked other than
if it has been ensured that the fireplace can only be operated with opened fas-
tening by special safety equipment. The cross-section must not be narrowed by a
fastening or a grille. This measure is not necessary with LAS chimneys. A shut-off
valve must be installed, where the combustion air feed line runs outside the build-
ing. In doing so, it must be possible to easily determine the shut-off valve setting
from outside of the connecting line. In this version, the pipe should be insulated
to prevent condensation. The pipe should be positioned, so that any condensation
formed can run out of the pipe and any water or other foreign substances from
outside cannot get into the stove. In accordance with regulations, combustion
air piping crossing a fire wall in buildings with more than two storeys must be
established in such a manner that smoke or fire cannot be transmitted to other
floors or fire compartments. Country-specific and local fire safety regulations
must be observed!
SPARTHERM QUICK COUPLING - SQC COUPLING
Compatible with the following stoves:
• Senso S
• Piko / Cubo S/M/L
• Passo XS
• Passo S/M/L
• Redoro S/M
The installation location of the stove must be determined according to the
specified technical data for the supply channel / hole. For direct wall mount-
ing, the combustion air and flue gas connection must be prepared on one
level. The stove is delivered with the fitted SQC coupling and the adjustable
feet extended. In this condition, the connecting piece is in the air, and there
is no contact to base unit. Therefore, the stove can be transported as usual
with the normal tools (e.g. sack truck).

2. Remove the lower cover part by grabbing it at the side and pulling it
towards to the front.
3. Connect the connecting pipe shown here in blue with the receiving
unit for the SVS connecting piece.
4. After connecting the combustion air connection, push the lower cover
part onto the receiving unit as shown in green here and fix it with the
four countersunk screws.
2.3.2.3 ROOM-AIR-INDEPENDENT
The RLU stoves have been developed for use with residential ventilation systems
for a vacuum range of up to 8 Pa in the installation area and can be operated
without additional safety equipment. The combustion air must be supplied in
airtight lines from the outside or via an LAS system to the device for room-air-in-
dependent operation without fail. To do this, the combustion air duct must be
permanently sealed to the combustion air neck (connection type back/side or
bottom) of the stove.
When connecting the RLU stove to a combustion air line, the TROL instruc-
tions (technical rules), the DIN 18896, etc. must be observed and applied.
In particular, ensure that the dimensions are adequate!
Country-specific and local fire safety regulations must be observed! Make
sure that the pipes are always airtight.

GB 14
2.3.3 FIRE SAFETY
The handover inspection of your stove before commissioning is performed
by the chimney sweep responsible. You can also advise the chimney sweep
prior to installation about installation conditions on site, and can provide
advice on how to install your stove properly.
General Information on fire prevention
Stoves are heat generators and are subject to regulations and necessary
measures for fire protection. The fire regulations and the recommended
minimum clearances of the device must be observed even when selecting
the installation site. Basically, a minimum wall clearance of 5 cm to
the back wall must be adhered to. For reasons of safety and fire
protection, larger clearances must be ensured to protected walls or
combustible materials.
In the following table on page 17, the permissible clearances are docu-
mented according to the type of the stove and the type of on-site mounting
wall. Using the diagrams (Fig. 19-23), match the mounting situation, taking
into account the specified distances that need to be complied with.
Follow the instructions for fire protection during installation and
ask your local chimney sweeper.
• Mounting walls that are non-combustible or not to be protected are
suitable to withstand permanent exposure to temperatures > 85°C thanks
to their structure and their material type.
• Mounting walls that are combustible or to be protected (e.g. timber frame
construction) must be protected from temperatures > 85°C.
Before installing the stove, it is necessary to evaluate the mounting walls. If
the type of mounting wall cannot be clearly assigned, a specialist (chimney
sweep) must be consulted.
• Wallpaper as wall coverings in accordance with DIN 4102-1 are
non-combustible components and do not require special precautions
for fire protection. Ensure here that the underlying structure of the wall-
paper (e.g. timber frame construction) is very easily ignited or must be
protected and appropriate precautions must be taken!
• Ensure that the specified minimum clearances to the back and side wall
must be adjusted for the rotary devices.
• Ensure that the minimum clearances from chimney connecting piece to
combustible components are adhered to (see „2.3.5 Connecting piece“
on page 18).
• Combustible objects must not be located at a distance of 50 cm above
the fireplace!
Floor coverings near the stove
Floors in front of the combustion chamber opening have to be protected
from combustible materials by a board made of non-combustible materials.
The board must extend over at least 50 cm to the front and at least 30 cm
to the side (Fig. 19-23 C + D) (measured from the combustion chamber
opening or viewing window)!
No combustible components, furniture, curtains or decorations may be
placed in the area of direct radiant heat of the fire door or inspection glass.
This distance may be reduced to 400 mm if radiation protection plates are
installed between the fireplace and combustible structures on both sides.

GB 15
Minimum distances to adjacent components
Depending on the view pane arrangement (see the following graphics) of
your stove and the type of mounting walls, the distances from the table are
to be adhered to.
The following describes
• Distance A as the minimum distance of the stove sidewall to the mount-
ing wall
• Distance B as the minimum distance of stove back wall to the mounting
wall
• Distance C as the area of direct radiant heat in front of the view pane
(n) of the stove
Special note on minimum side distance
Minimum side distance (Fig. 17 (A)) describes the minimum distance from
the stove to the side mounting wall and is valid from the back mounting wall
to the beginning of the area of direct radiant heat (E) of the front panel.
In stoves with curved front pane or a wide area of direct radiant heat, the
minimum wall distance (A) must be adjusted to the extending area of direct
radiant heat.
Determining the area of radiant heat
To layout the area of direct radiant heat of the stove, put a measuring
instrument (ruler or measuring tape) on the surface of the view pane and
determine the centre of the fireplace past the side door pillar (Fig. 18). In
the resulting angle and the distance A1, there must be no combustible or
components to be protected on the sides.

2.3.4 CUT-OFF DEVICE
Exhaust systems must be created in accordance with the Technical Rules
of Tiled Stoves and Hot Air Heating System Trade (TROL). Stoves should
have a shut-off device in the exhaust gas flue. These devices must not be
self-closing and must not be positioned such as to prevent or hinder the
inspection and cleaning of connecting pipework. The position of the shut-off
device must be visible from the outside, e.g., from the position of the oper-
ating handle. Shut-off devices may only be installed in the exhaust manifold
or collecting pipe, the flue gas pipe stub or the pipeline connecting piece.
2.3.5 CONNECTING PIECE
Your stove is connected to the chimney with Ø 150 mm/Ø 160 mm connecting
pieces made of steel plate which is at least 2 mm thick. These connect-
ing pieces must satisfy the requirements specified in DIN 1298 and DIN EN
1856-2, and must be connected to the chimney system in accordance with
the requirements specified in DIN 18160 or the country-specific regulations.
It must be ensured that the flue gas pipe is installed in the shortest pos-
sible route upwards towards the chimney. To achieve this, ensure that the
flow of flue gas is redirected as few times as possible. Ensure that the flue
pipe is stable; where appropriate, the flue pipe may need to be secured with
brackets. If the flue leads through a combustible wall or is located close to
any combustible components, the flue is to be insulated according to the
respective regulations. The connecting line must always be mounted in such
a manner that it is possible to clean the connecting line at any time.This must
be ensured through a sufficient number of cleaning openings. If the stove is
rotatably mounted, the connecting pipe must be installed so that no negative
effects occur on the fixing. The flue pipe must not also turn. The minimum dis-
tance from the chimney connecting piece to any combustible components can
increase the distance from the stove to combustible components, in accord-
ance with the manufacturer specifications for the flue pipe. The specified
minimum distances to combustible components as stated in these instructions
refer to the fireplace and must be adjusted if necessary („2.3.3 Fire safety“
on page 14).
Ensure that a cleaning opening is located above the flue pipe connection with
gas evacuation to the top.
2.3.6 INSTALLING THE HEAT STORAGE STONES ON
TOP
The heat storage stones delivered with your stove are packed separately
due to their heavy weight. After the stove has been assigned its location in
the installation space, you can begin with the installation of separate heat
storage stones.
Insert the heat storage stones from the outside to the inside. When the stove
is connected with flue gas connection at the back, the heat storage stone
must be placed in the centre. If you connect the stove at the top, the central
heat stone is not required.
To insert the heat storage stones, remove the cover and the plate to control
the supply of heat. Then insert the heat storage stones as shown.

2.3.7 INSTALLATION OF THE WATER-BEARING
COMPONENTS OF THE SENSO M H2O / PIKO H2O
Assembly of the water-bearing components, the necessary safety devices,
temperature sensors and similar components must always be carried out by
a specialised company. The Mellino H2O / Piko H2O must be installed with all
water-bearing components accessible and inspectable at all times!
The stove as well as all associated immersion sleeves, connectors, moulded
components and pipes must be have the pressure checked prior to commis-
sioning and checked for airtightness.
2.3.7.1 CONNECTIONS OF SENSO M H2O / PIKO H2O
The connections on the Senso M H2O are located on the back and can be
guided from the inside downwards using the flexible attachment kit. The Piko
H2O has its connections on the bottom which can be routed to the back and
the side with the flexible attachment kit.
The connections have transport caps and brass stops for transport purposes.
This must be removed prior to installation. The connections are clearly labelled
and must not be used other than for the specified purpose! In particular, the
integrated safety device (safety heat exchanger) must not be used to heat
water.
For easy installation of the pipes, etc. when during connection through
the floor, there is an installation template that can be downloaded on our
website www.spartherm.com in dealer login. The installation tem-
plate is valid only in conjunction with the flex attachment kit.
Alternatively, an installation template in the scale of 1: 1 can be requested in
print format from us. The flex attachment kit can be ordered for easy and quick
connection of pipes in the floor and the internal connections.
