1.3.1 Fire door (A) 

The  fire  door  is  opened  by  pulling  the  handle  outwards;  a  protective  glove  is  supplied  for  that  purpose  (the  handle 
becomes very 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. 

 

1.3.5 Oven (E) 

The oven is heated by the combustion gases flowing around it and its temperature can be read on the thermometer on 
the  door  glass.  A  sufficient  draught  and  clean  fume  ducts  are  essential  for  optimum  efficiency.  The  oven  is  supplied 
with  two  grills. When  putting  pans  in  the  oven,  take  into  account  the  possible  rising  of  food  and  the  minimum  space 
between pans and the sides of the oven (min. 20 mm). 

 

1.3.6 Secondary air (F)  

The stove secondary air is for burning unburnt gases produced by the combustion process.  
The secondary air must be opened especially when burning wood. 
It is controlled by the lever on the back of the stove: in position A the secondary air is fully open and in position Z it is 
closed. 

 

1.3.7 Cast iron hotplate (G) 

The  cast  iron  hotplate  has  concentric  rings  of  max.  diameter  320  mm  in  the  fire  zone  and  a  rectangular  plate  for 
possible  insertion  of a tank containing  water.  The rings can be  removed  using the poker, to  inspect  the firebox or  for 
inserting cauldrons.  

 

1.3.8 Baffle control lever (H) 

By  turning  the  lever  located  on  the  left  of  the  flue  connection  to  position  A,  the  fumes  are  forced  to  flow  around  the 
oven, thus raising the temperature in an even way. When the lever is turned to position Z, the combustion gases flow 
over the oven and under the cast iron hotplate directly towards the outlet collar. 
Position “Z” is advisable when lighting the stove and during summer operation. 
Position "A" must be used for oven cooking. 

 

 
 
 
 
 
 
 
 
 
 
 

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
