7. If you do not want to add more fuel and the dose has burnt out, set the regulation of air to
the left to the minimum (
Fig. 9
). This will prevent burning air getting into the chamber and will
prolong the heat phase. The coal will remain hot in the chamber longer and the heat will not
escape through the chimney.
Notifcation: During active burning (visible fre), never close the air supply and do not
smoother the fre! Air fowing into the burning chamber cools the ceramic glass. If closing
the supply of air, it can be overheated and irreversible changes can occur in the crystalline
structure of the glass. During burning with an insuffcient air supply, an excessive amount of
harmful carbon monoxide - CO will originate. In the case of opening the air supply too fast,
there may be a rapid reaction of the collected gases with the oxygen.

Note!! In all the models the opening of air supply is when it is marked
number 1,the closing of air supply is when it is marked number 0.
4.2. OPERATION IN THE TRANSIENT PERIOD
For the correct function of the fireplace insert, a sufficient draught in the chimney is
required, which depends on the outdoor temperature. In winter when the outdoor
temperature is low, the chimney has the highest draught level. A problem with a sufficient
draught may occur in the transient period (before and after winter). A higher outdoor
temperature worsens the burning and increases the volume of the smoke. These undesirable
phenomena can be prevented as follows:
- When starting, increase the first dose of the fuel by 30 %, to quickly achieve the requested
draught in the chimney.
- Do not cut the wood into small pieces; this will result in heating the chimney too fast and
stabilize the draught.
- Leave the lever for the air supply in maximum position.
- Only add well dried wood.
