1. Safety information
1.1 Intended use
The unit is designed to heat the air in a room by burning
suitable types of fuel and is exclusively intended for use in
private households.
The unit is designed as a time-limited fireplace, the burning
time of which can be extended by refuelling it.
§ Time-limited fireplace according to DIN EN 13240,
category 1 a.
The following conditions apply to using the unit:
•Only the appropriately authorised target group may install
or use the unit or perform other activities on the unit.
•The unit must be installed in a dry living space in an
enclosed building.
•Prior to start-up, acceptance by the responsible authorities
is required (in Germany e.g. the district chimney sweep).
•The unit is exclusively fuelled by natural, air-dried logs
(remaining humidity max. 20 %) or compressed wood
pieces.
§ Compressed wood pieces approved according to
DIN EN ISO 17225-3.
•Extending the combustion period (“permanent fire”)
by fuelling the unit with larger quantities of wood or by
extracting the combustion air is not permissible.
•Operation only with closed firebox door. Only open the door
for heating, refuelling and cleaning.
•The national and regional regulations and directives are
observed.
¨“10.3 Standards and regulations” (page 49).
•The requirements and safety information in these
instructions are observed.
Any other use is regarded as unintended use.
The manufacturer is not liable for damage caused by
unintended use.
1.2 Authorised target groups

1.3 Behaviour in emergencies
ANever put yourself at risk of death.
If it is possible without endangering yourself:
AWarn others.
AInstruct others to leave the building.
ADeactivate the unit.
1.4 Chimney fire
The chimney requires regular cleaning (e.g. in Germany by the
district chimney sweep) to prevent formation of a layer of soot
in the chimney.
Burning wood may generate sparks that can enter the chimney
where they may ignite the layer of soot.
Signs of a burning chimney:
•Flames emerge from the mouth of the chimney.
•A large amount of flying sparks.
•Smoke and unpleasant odours.
•Chimney sides grow very hot.
In the event of a chimney fire:
AAlert the fire brigade by calling the emergency services
number.
ARemove flammable objects from the vicinity of the chimney.
Never attempt to extinguish the fire with water!
High temperatures will generate extreme amounts of steam
even from a small amount of water. The resulting pressure can
be a danger to people and can damage buildings or the stove
system.
1.5 General safety information

Product information
Assembly and operating manual | Senso & Sino | 12.2022 | EN
2. Product information
2.1 Functional principle
The combustion air flows through the combustion air
connection into the air connection box. From there, the air
is guided to the firebox and combustion. The volume of
combustion air can be controlled using a combustion air slider.
2.1 / 1
A
B
There are two types of combustion air:
A Primary air
Oxygen-rich, non-preheated fresh air guided toward the
fuel from the bottom. Primary air is primarily used for light-
up.
B Secondary air
Pre-heated, variable air flow guided into the firebox from
above to ensure even, efficient combustion.
2.2 Operating modes
The unit can be used in two different operating modes:
•Room air sealed operation – only for RLU stoves.
The unit is supplied with combustion air from the outside or
from other rooms (e.g. cellar) through a combustion air line
connected to the rear or bottom of the unit.
§ The unit meets the requirements for approval by DIBt
(German institute for construction technology) for
room air sealed fireplaces and solid fuels according to
DIN 18897-1.
•Room air dependent operation –
for RLA and RLU stoves.
The unit is supplied with combustion air from the
installation room. The combustion air is supplied to the
unit through the air openings. A combustion air line is not
required but permissible (e.g. for operation together with
controlled ventilation and venting systems). Rotatable
models can only be operated in room air dependent mode.
2.3 Material
The unit consists of a steel body, which meets the requirements
for fireplaces.
§ The unit has been tested according to DIN EN 13240.
The firebox lining contains built-in components or cover panels
made of fireclay, ceramics, vermiculite or refractory concrete.
Cracks may form in these components as a result of e.g.:
•Physical and production-related residual moisture in the
components escaping during the heating process.
•High temperature differences.
Surface cracks do not affect combustion. If wide cracks form
or pieces break out uncovering the unit structure, the firebox
lining must be replaced.
2.4 Protective devices
•Self-closing firebox door.
•High-temperature resistant ceramic glass window.

Information on the model (e.g. type, inspection number, year of
manufacture) can be found on the type plate.
The type plate is required for regular inspection of the unit (e.g.
in Germany by the chimney sweep).
¨Figure 2.6 / 2 (page 8).
2.9 Nominal heat output
The nominal heat output of the unit can be checked in the
defined position “NHO position” of the combustion air slider.
To adjust the NHO position, first move the combustion air slider
all the way to the left to close the air supply. Then push the
combustion air slider 18 mm to the right.

6 7 9 9 10
A ruler applied directly to the outer edge of the cover panel
makes it possible to determine the NHO position of the unit.
The nominal heat output can only be achieved by adjusting
the NHO position under test bench conditions. In heating
mode the value represents an approximate value. The ideal
position of the combustion air slider depends on the situation
and is affected by a variety of factors.

3. Types of fuel
3.1 Information on types of fuel
Wood primarily consists of cellulose, lignin, resins, fats and
oils. Wood does not burn directly. The components of wood
become gaseous at different temperatures and burn up if
enough oxygen is available.
Using fuel with a residual moisture of > 20 % will lead to
decreased output and increased emissions.
Good, fast combustion and good gas release are crucial for
problem-free operation of the unit.
Bark prevents moisture from escaping. Gas release is only
ensured at “injured” sections of wood, making it necessary to
split the wood.
If the temperatures required for gas release and clean
combustion are not reached, this will interfere with combustion.
The unburned substances will negatively impact the
environment and will adhere to the stove system as deposits
(e.g. soot, tar). These deposits increase the effort required for
cleaning and may damage the stove system.
Hardwood is particularly suitable as firewood. It burns slowly
with a calm flame and turns into embers that glow for a long
time.
Softwood is rich in resin, burns faster and has an increased
tendency to generate sparks.
We recommend beech wood as the ideal fuel.
§ According to DIN EN 13240 a combustion period of
45 min in a time-limited fireplace requires a fuel volume of
1.4 kg of wood.
3.1 / 1
170 - 250
~ 80
~ 80
1.4 kg of wood corresponds to two average logs (length
170 – 250 mm, width/height approx. 80 mm).
1 kg of beech wood generates an output of approx. 4 kW.
Compressed wood pieces have an approx. 20 % higher output.

Assembly and operating manual | Senso & Sino | 12.2022 | EN
3.2 Permissible types of fuel
Only the following types of fuel are approved for use:
•Natural, air-dried split logs (residual moisture max. 20 %).
•Compressed wood pieces
§ Compressed wood pieces according to
DIN EN ISO 17225-3.
The following fuel types are not permissible:
•Chemically treated wood
•Painted or varnished wood
•Synthetically coated wood
•Damp wood (residual moisture higher than 20 %)
•Chipboards
•Wood of Euro pallets
•Trimmings
•Bark waste
•Pellets
•Coal
•Coke
•Household waste
•Plastics
•Waste paper
•Old clothes
§ Burning non-permissible types of fuel is punishable by law
in many countries e.g.:
•In Germany as a violation of the Federal Immission
Control Act (BImSchG).
•In Switzerland as a violation of the Clean Air Act (LRV).
3.3 Permissible igniters
The following igniters are permissible:
•Igniter cube
•Igniter pad
•Wood wool igniter
•Igniter wood
Other igniter types are not permitted.
Never use:
•Flammable fluids and fire accelerants (e.g. ethyl alcohol or
kerosene) – there is a risk of deflagration!
•Paper – burns fast and results in flying ash!
3.4 Fuel storage
Storage outside of buildings:
•If possible, store the fuel on the sunny side of a building.
•Ensure that the storage location is ventilated and protected
against precipitation.
•Stack logs loosely along a wall and support them on at
least one side.
•Ensure that there is a gap between logs so that the air
flowing through them can carry off the moisture escaping
from the wood surface.
Storage in buildings:
•In a dry and well-ventilated room.
Storage of freshly cut (green) wood in film or in closed rooms
without sufficient air exchange prevents drying and causes the
wood to become mouldy.
Storage period:
•At least one year for soft wood (e.g. coniferous wood,
poplar).
•At least two years for hard wood (e.g. beech, oak).
We recommend a drying period of 2 – 3 years.
3.5 Size of the fuel pieces
•Small logs (width/height approx. 60 mm) for fast burning
and briefly high output.
•Large logs (width/height approx. 100 mm) for slow, even
burning.
Ideal log size:
•Length ideally approx. 180 mm.
•Maximum length 250 mm.
•Width/height approx. 80 mm.
