Page 8
Danger of poisoning and suffocation
The flue gases from the pellet stove contain components dangerous
to health, including carbon monoxide.
Self-protection measures for rescuing unconscious persons:
Thoroughly air closed rooms before entering them.

Note
Carbon monoxide
- Blocks oxygen take-up and causes death
by suffocation
- Is a colourless and odourless gas
- Is produced in incomplete combustion processes
- Is heavier than air and collects on the floor.
Danger of electric shock
The following applies to main voltages with 50 Hz and an effective
duration of more than 1 second:
Currents over 50mA and voltages over 50V are life-threatening!
2.3. Liability
In the case of personal injury or damage to property, the manufacturer is only liable

2.6. General information about the fuel
You have chosen to heat your home with CO2neutral wood as a fuel
. Pressing of waste wood into standardised wood pellets means that an inexpensive
fuel can be produced from untreated wood waste and converted cleanly and ex-
tremely efficiently into thermal energy when combusted.
2.6.1. What are wood pellets?
Wood pellets consist of 100% untreated wood waste (wood chips, sawdust, etc.). The
dry wood waste is shredded and pressed under high pressures to form wood pellets.
The addition of binders or other additives is not permitted.
The standards DIN 51731, ÖNORM M 7135 and DIN plus specify the following qualities
for wood pellets 6 mm in diameter:
Length: 10-33 mm
Diameter: 6 mm
Bulk weight: Approx. 650 kg/m3
Calorific value: 5 kWh/kg
Residual mois-
ture:
< 10%
Ash content: < 0.5 %
Density: 1.12 kg/dm3
2 kg wood pellets are equivalent in energy to approx. 1 litre of heating oil. Volumetri-
cally, 3 m³ wood pellets will replace approx. 1000 litres of heating oil.

Note
Wood pellets must be protected against moisture! They
will expand greatly if exposed to moisture and can no
longer be used as a fuel.
Keep wood pellets dry during transport and storage.
2.6.2. How can you recognise "good" wood pellets?
Differences in the quality of wood pellets can be due to the preparation and com-
pressing of the raw material. The following quality features can be used for a basic
visual check of wood pellets when purchasing them. Precise quality features can
only be determined with suitable technical analysis equipment.
Superior quality The surface is shiny and smooth. The wood pellets are uniform in
length and have a low dust content.
Inferior quality The surface has vertical and horizontal cracks. The wood pellets
have different lengths and a high dust content.

4.4. The operating phases
4.4.1. The start phase
Wood pellets are fed into the burn grate for a specific time during the start phase.
The ceramic ignition is activated at the same time. The wood pellets normally ignite
after approx. 5 minutes with a visible flame. A precisely defined quantity of pellets is
then conveyed into the burn grate to build up and maintain the bed of glowing em-
bers. The pellet stove then starts the heating mode.
4.4.2. The heating mode
The control system allows the Solida pellet stove to be operated automatically or
semi-automatically. The stove is delivered with the automatic mode set as standard.
If it is necessary to limit the maximum heating output, the stove can be operated
semi-automatically.
4.4.2.1. Setting the operating mode Automatic
If it is switched on and the set room temperature is undershot by at least 1.2 °C, the
stove will start operation. If the set room temperature is exceeded by 0.6°C, the cool-
ing phase is initiated.
4.4.2.2. Setting the operating mode Semi-automatic
The semi-automatic mode allows the heating output to be set manually. This means
that the stove only starts operation, after the start phase, using the maximum heating
capacity set manually. The automatic start and switch-off when the maximum room
temperature is reached is also active in the semi-automatic mode.
Press the button.
Scroll to page K11 with the button.
Select Automatic/Semi-automatic with the or buttons.
Use the button to leave the customer menu and save the
parameters.
The menu is automatically closed and the parameters
saved after 60 seconds.

Page 14
4.4.3. The cooling phase
The screw conveyor is switched off when the cooling phase starts and no wood pel-
lets are conveyed into the burn grate.
4.4.4. Standby mode
Once the set temperature has been reached, the stove switches to the
cooling phase.
When the cooling phase is complete, the standby mode starts. The standby mode
signals that the stove will start heating again automatically when the switch-on tem-
perature is undershot.
4.5. Stove operation with external actuation
The Solida pellet stove offers the pos-
sibility of actuation via an external
thermostat or an external timer. Con-
nection can be implemented on the
rear using the terminal strip next to
the power supply inlet. To connect
the external control system, remove
the cable link (Fig. 6) and connect
the cable of the external control sys-
tem with the RT terminal of the termi-
nal strip.
Fig. 6: Terminal strip with cable link
The pellet stove must be actuated potential-free! Never
apply an input voltage! Only use shielded cables! The
room thermostat may only be connected by a special-
ist!
The external contact must be activated in the control system, simply removing the
cable link is not sufficient.
Activation of the external contact:
Press the button.
Scroll to page K17 with the button.
Activate/deactivate the external contact with the or
buttons.
Use the button to leave the customer menu and save the
parameters.
The menu is automatically closed and the parameters
saved after 60 seconds.

Page 15
Combinations/Priority
If automatic operation of the stove is set (external contact and timer), the required
selection must be made after pressing the
button, using the or buttons.
A query appears in the display after switching on:
The stove starts immediately when Manual is selected, regu-
lating according to the set target temperature until it is
manually switched off again.
The external contact has priority over the timer with this se-
lection.
.
When the external contact is closed, the stove switches on even when the timer is set
to set-back mode.
If operation is activated simultaneously with the external contact and the time, the

4.7. Safety equipment
The cooling phase starts immediately if there is a malfunction and the fire will go out
within several minutes. A restart is only possible manually after the malfunction has
been resolved (press the Start button).
4.7.1. Power failure
The control unit activates and maintains the cooling phase if there is a power failure.
The device will then start operating again by returning to the start phase, even if the
power failure only lasted a few seconds.
A slight amount of smoke may be produced during a power failure, but does not
pose any danger as it is produced by the small amount of fuel still in the burn grate.
4.7.2. No flame formation during the start phase
The stove switches off automatically if no flame is formed during the start phase and
if the exhaust gases do not reach a minimum temperature of 60°C (insufficient fuel
supply).
4.7.3. Device overheating
A high-temperature monitor is located in the pellet chute and the combustion
chamber, these can independently switch off the pellet supply if overheating occurs.
The exhaust and convection air fans continue operating in this case and ensure that
the stove cools down rapidly.
The stove switches off automatically if no flame is formed during the start phase and
if the exhaust gases do not reach a minimum temperature of 60°C (insufficient fuel
supply).

5.2. Installing the Solida pellet stove
The following specifications regarding floor protection, distances from flammable
materials and the flue pipe connection may differ from regional and official regula-
tions. Please contact your Calimax sales partner or appropriate local authority if
there are any questions.
5.2.1. Floor protection
For practical cleaning aspects, it is recommended that the pellet stove is set up on a
fireproof base plate that is at least 5 cm wider than the back and sides of the stove
and extends at least 15 cm at the front.
It is not absolutely essential to have a fireproof base under the stove as excessive
temperatures are not produced in the lower section of the stove during operation.
The combustion chamber door is for cleaning purposes only and is not an ignition
door. It must not be opened during operation!
Please note the local regulations in all events, as they
may differ from the above specifications!
5.2.2. Distances from combustible materials
The following minimum distances from
combustible materials must be complied
with:
Back: 5 cm
Sides: 15 cm
Front: 80 cm
5.2.3. Flue connection
The flue must be connected to the chimney according to local regulations. Please
contact your Calimax sales partner or appropriate local authority if there are any
questions.
Do not lay any cables over the flue pipe!
The minimum draught requirement in the chimney must be greater than 0 Pa!

Page 20
5.2.4. Chimney
The flue system must be calculated according to EN 13384-1. A positive chimney
evaluation must be present before the pellet stove can be used. Excessive pressure
must never be generated in the connection piece between stove and chimney.
The minimum draught requirement must lie between 0 Pa and 25 Pa.
5.2.5. Pellet stove-chimney connection piece
The connection piece between the pellet stove and chimney entry must be designed so that
the exhaust gases can enter the chimney with low pressure loss and low cooling (see DIN
18160). It must be accessible for checking and cleaning.
The connection piece must be gas-tight in design.
5.2.6. External air inlet
Connect a hose or other suitable air conduit to the air inlet on the back of the stove.
The end of this air conduit must be located in the open air or another well-ventilated
room in the building.
The following table shows the applicable air inlet dimensions:
Diameter:
Inlet conduit:
Maximum
length*
Maximum number of
90% elbows
50 mm 0.5 m 1
70 mm 1 m 1
100 mm 3 m 3
* The data are valid as applicable. If using a flat conduit or other shape, the cross-section must be selected accord-
ingly.
The combustion air volume may not be sufficient at full operating load if the dimensions are too small.
This will cause slag formation in the burn grate and accumulation of pellets.
Individual combustion air regulation for the pellet stove
is necessary if an external air supply is used.
5.2.7. Simultaneous operation of pellet stove and air-conditioning
The simultaneous operation of a pellet stove and an air-conditioning system (e.g.
controlled ventilation, air extraction, etc.) can lead to malfunctions during the start
up process and during pellet combustion. Please contact your Calimax sales partner
for any questions regarding simultaneous operation and about legal guidelines.
5.2.8. Multiple configuration
Multiple configuration refers to a chimney system where several stoves using different
fuels can be connected.
The pellet stove is not suitable for a multiple configuration.
