4.3.   Burning wood 
310GX: The best way to control the fire is to completely close the lower air slide in 
the ash-door,  which  you use to get the  fire  started, and to regulate the air  supply 
with the  air slide in the side-door only. In case the air supply through the this slide 
seems insufficient, or  if  you  would like  to  fan the fire, you  can partially  open the 
lower air slide in the ash-door for a while. 
Always keep the stove doors tightly closed. Never let the doors open when the fire is 
burning. 
Add extra fuel when necessary. Never add too much fuel. It is best to fill the stove 
for one third and to top it up on a regular basis. 
Always open the filling door slowly and for a short space of time. Before filling up, 
the  charcoal  bed  should  be  carefully 
spread  open.  Check  whether  the  coals 
are glowing enough just behind the log 
retainer, so  that the added fuel will im-
mediately  catch fire.  If  necessary you 
can open the lower air slide for a while. 
Open  stacking  will  make  the  logs  burn 
very intensely, as the oxygen can easily 
reach every part of the fire. This method 
of  stacking  is  applied  when  burning 
wood for a short while. Compact stack-
ing will make the fire burn slower, as the air can only reach the outer parts of the 
fire. This stacking method is best used when burning for a longer while. 
Low  intensity  fires  cause  tar  and  creosote to  deposit  in  the  chimney  after  a  long 
period of time. Tar and creosote are highly combustible substances. Thicker layers 
of these substances might catch fire when the temperature in the chimney increases 
suddenly and  steeply.  Therefore  it  is  necessary  for  the  fire  to  regularly  burn very 
intensely, so that thin layers of tar and creosote immediately disappear. 
Low intensity fires also cause tar to deposit on the stove panes and doors. 
When it is not too cold outside it is better to let the stove burn intensely for just a 
few hours a day. 
4.4.  Burning coal 
WHEN BURNING CHARCOAL USE ONLY THE AIR SLIDE UNDER THE GRILL. 
As soon as the fire is sufficiently stable and there is enough glow, the first shovel of 
coals can be put onto the fire. Complete the filling once the coals have caught fire. 
Make sure you do not quench the fire by putting too much coals onto it at a time. 
Once the fire has burned for a while, adjust the air slide at the bottom of the door. 
Before adding some extra coals, open the air slide below completely. Use the sup-
plied shovel,  to bring the ashes in the  ash plate; then add the coals. After a few 
minutes, adjust the air slide. Add some more coals until you can only see the glow 
of the previous filling.  
When the fire basket or the cast-iron plate fins are red-hot, you are heating too in-
tensely.
