3SAFETY DIRECTIONS
This device shall not be used by people with lower physical or mental abilities,
children, or people without experience. Children should always be supervised not to
touch the device. There are hot surfaces that might cause injury!
It is recommended not to install the stove on floor made of flammable material. If so, a
protective layer of non flammable material, of minimum thickness of 15 mm, should be
positioned between the floor and the device.
All electrical connections must be performed by an authorized professional. The device must be
grounded. Connect the device plug to a grounded inlet. Make sure that the cable is not pressed
under the stove or touching any hot surfaces.
It is important to use dry wood (humidity≤ 20%), cut at least one year before use, of 40 cm
length for Airvent 25 and of 35 cm length for Airvent 15.
In case of blackout, stop immediately the combustion by closing the air inlet (7,8) and open
completely the exhaust damper (2). If you have a UPS with battery installed, do not add any
more fuel in the fire chamber. If no UPS is installed, remove wood from the fire and reduce the
fire to minimum possible.
4INSTALLATION DIRECTIONS
Choose the installation area so that the frontal face of the stove is directed to the space you
want to be heated.
Set the adjustable feet so that the stove is in horizontal position.
Make sure the chimney installation is appropriate. Connect tight with the chimney. If there are
horizontal parts of the chimney, they should have an inclination of at least 30owith the floor.

5USE DIRECTIONS
5.1 General directions
Before you put the stove in function check the following:
The exhaust damper (2) must be in fully open position.
The air inlets (7, 8) must be open.
The stove is connected to electricity.
The ash box is clean.
Add some small pieces of wood in the furnace, and ignite with an appropriate tinder (DO NOT
USE gasoline, alcohol or similar flammable liquids) and close the door. If necessary,
open a little the ash drawer for some additional air inlet.
Add some bigger wood logs, 1-2 every time, without opening the door too fast, to avoid smoke
leakage. Do not add too much wood, because it will create excessive smoke and heat. ‘
DO NOT USE AS FUEL THE FOLLOWINGS:
Wood with moisture or that has been processed
Wood shavings
Cardboards and paper
Plastic or other waste materials
Before you clean the ash, make sure there are no burning remains. Even if the ash seems cool,
there can still be hot particles in the interior.
5.2 Use of control panel
The control panel is already preset for the device. It activates the fan at the temperature of
50oC and above.

6
In PROP mode, the fan speed modulates according to the sensor temperature; the higher the
temperature, the higher the fan speed.
If you want to change some parameters (activation temperature, min/max fan speed etc.) you
can enter the control panel menu.
ON/OFF function
Keep pressed the P1 button for ON/OFF function. In OFF mode the lamp L1 will be activated.
Mode selection
MANUAL: The MAN indication is highlighted. The fan functions at a steady speed, regardless
the temperature of the sensor.
AUTOMATIC: The AUT indication is highlighted. The fan starts to function at a steady speed
when the selected temperature has been reached (SET).
PROPORTIONAL: The PROP indication is highlighted. The fan speed is modulated according to
the sensor temperature, within the limits (SET÷ SET+dEL).
STANDBY: (If Stb=1) If the control panel is set to OFF and the sensor temperature is higher
than the tSI value, then the control panel automatically changes to ON function.
SECURITY: (If SIC=1 If the sensor temperature is higher than the tSI value and the MANUAL
mode is activated at P0, then the control panel switches automatically to PROP mode after 10
seconds.
ALARM: (If Enb=1) If the sensor temperature is higher than the tAL value, then a sound
alarm is activated. This alarm can be deactivated for 5 minutes by pressing any button. After 5
minutes it is reactivated if the temperature is still higher than the safety limit.
Main menu
Mode selection
Press the P4 button for the current mode to appear on screen. By pressing again the P4
button you can cycle through the modes which will appear on screen.
The mode is selected automatically after 5 seconds.

By pressing the P2 or P3 buttons you can check the current fan speed (P0=OFF at Manual,
P1=minimum speed, P10=maximum speed).
This function is not available on PROPORTIONAL mode
In AUTOMATIC mode the fan speed can be set from P1 to P10.

Alarm or Error signals
Lo=low temperature (temperature below 0oC: sensor not connected)
Hi=high temperature (temperature higher than 180oC: sensor short-circuited)
ATTENTION: The sensor cable is designed for temperature until 250oC. It must not come in
contact with metallic parts of the stove that have a temperature higher than 250oC.
All electrical connections of the device must be executed by an experienced professional. Make
sure there is no voltage when electrical works are executed.
Parameters menu
To enter the parameters menu keep presses P2 and P3 buttons for 5 seconds.
Press the P2 or P3 button to check all the parameters, then press P4 to see the value
assigned to each parameter. Afterwards, press again P2 or P3 to change the value. Press P4
to store changes and return to the parameter list.
Changes are stored and you exit from the menu after 5 seconds of inactivity.
