1.3.1 Fire door (A) 

The  fire  door  is  opened  by  pulling  the  handle  outwards;  use  the  protective  glove  supplied  with  the  stove  when  the 
handle is hot. There are air inlet slots around the top and bottom edges of the fire door to keep the glass clean. 

 

1.3.2 Ash door (B) 

The ash door is opened by pulling the handle outwards, to access a compartment with a removable ash pan inside. 

 

 

1.3.4 Baffle inspection door (D) 

This door gives access to the baffle located under the oven for cleaning. 

 

 

       

Fig.2 Primary air control 

1.3.3 Primary air control (C) 

By means of the revolving air control on the ash door the primary air can flow into 
the  lower  part  of  the  stove  through  the  ash  pan  and  grate.  The  primary  air  is 
necessary for the combustion process, therefore make sure to empty the ash pan 
regularly so that the ash cannot obstruct the combustion air inlet. When the arrow 
is in position 0, the air inlet is closed; when the arrow is in position 3, the air inlet is 
fully open. 
Warning: Wider adjustments can cause overheating and damage to the stove
