3. OPERATION

3. 1 Fans

Fans at the bottom of the fireplace are operated by a three position switch (I, 0, II ).
You can vary the fan speed at any time. At a slower speed (I), operation will be quieter and the room will be
heated gradually. When operating with a strong fire, it is advisable to adjust the fans to a faster speed (II) to
cool the woodburner and heat the room faster.
In switch position (O), the fans will be turned off, but a safety thermostat will be able to activate them at
any time if the temperature at the lower part of the stove reaches 50ºC in order to protect the electric
components.
NOTE. To avoid overheating, the woodburner must be connected to the mains if there is a fire or ember
burning in it.

3. 2 Combustion

For good combustion that is clean and environment-friendly (CO-free), when the wood is well lit and it
has reached a high temperature, you must close the primary air inlet and keep the secondary air inlet
open. This will let the air for combustion (preheated) enter through the top of the fireplace next to the
glass and through the back wall below the deflector to ensure better gas combustion. You will notice this
in an increase in flames and temperature.
Woodburners and inserts are intermittent combustion appliances. This means that they should be lit,
loaded with an approximate weight of fuel as recommended by the manufacturer for each model,
followed by a full combustion cycle and fuel reloads after each combustion cycle.
Good combustion is necessary for optimum performance and a better view of the flames through the
glass. Guidelines:

Maintain a high and constant temperature in the fireplace. Accordingly, the fireplace door must be
closed at all times and opened only to load firewood, which must be done as quickly as possible.
Keeping the door open will cause the stove to cool down, it will worsen the combustion and make
lighting of the new wood more difficult.

Do not take a long time when loading firewood and wait for the end of the combustion cycle, when the
flames of the previous load disappear.
A full combustion cycle comprises the following:
1. A short period after reloading when the wood begins to heat up without flames. The time until the
flame lights is an indication of the fireplace temperature. If you wait too long to reload firewood, the
temperature falls too low and the new load of firewood does not light well. This has a negative effect
on combustion and dirties the glass.
2. The temperature of the firewood increases rapidly and it begins to break up, emitting gas that ignites if
the fireplace temperature is appropriate. The fireplace temperature begins to increase as the fuel
emits more gas and the flames increase.
3. After a certain period of time, which varies depending on the type of firewood, the maximum
temperature value is reached and the gases emitted from the firewood decrease slowly along with
the volume of the flames.
When the firewood gas emission is complete, the flame goes out and the firewood turns to burning
embers, that is the moment to add wood into the stove.
