Lighting the Stove  
 

We recommend that you have two or three small fires before you operate your stove to its 
maximum heat output. This is to allow the paint to cure in steadily and to give a long 
service life of the paint finish. During this curing in process you may notice an unpleasant 
smell. It is non-toxic, but for your comfort we would suggest that during this period you 
leave all doors and windows open. 
 
First, load the fire with starting fuel, i.e. paper, dry sticks and/or firelighters in the mode 
chosen, either wood or solid mineral fuel. 
 
Light the fire at the base leaving all air controls open. Allow the fuel to reach a steady 
glow and build the fire up gradually. Once you have a good fire established across the 
grate bed, further fuel can be added as required. 
 

Shutting Down 

In order to shut down the stove, close the primary air controls, then close the secondary 
air slider by moving the handle all the way to the left. If the controls are left in this 
position, the fire will be starved of air and will go out. If you want to revive the fire it is 
recommended that the primary air controls are open first, then open the secondary air 
slider. 
 

Warning! - 

The stove will remain 

hot 

for a considerable time after the fire has been 

extinguished. 
 

Notes: 
 
Warning! -

 Petroleum coke fuels or household waste must not be burnt on this appliance. 

Should any difficulties arise over fuel quality or suitability, consult your local approved 
coal merchant.
