The heat output of the appliance is controlled by the top air slide.
High heat output:
After establishing the fire and loading it with larger pieces of wood, leave it running with the top air slide fully open.
Running the appliance with the door open will not produce maximum heating in the room as it will draw a lot of already warmed air out of the room.
Similarly running the stove with the top air slide and the bottom air slide fully open will often not give the hottest fire as too much heat is lost up the flue and does not come into the room.
Note that this setting is not the most energy efficient as some heat is lost up the flue instead of being transferred into the room.
Do not overload firebox with fuel.
Low heat output:
The heat output of the appliance can be reduced by closing the top air slide (slide to the right) which will restrict the oxygen supplied to the fire thereby slowing down the rate at which the wood burns.
This setting will provide the best energy efficiency as the wood burns for longer. However, if not operated correctly may result in higher particulate emissions.
Prior to closing the air slide ensure that the fire is burning briskly. This may require leaving the air slide fully open for 10-15mins before shutting down.

5. RUNNING THE APPLIANCE
For the optimum between clean burning, and getting the best in efficiency from the heater, from the fully closed position, open the top air slide 4-5mm (bottom air slide is shut).
The top air slide can be adjusted to any position so desired depending on wanted heat output versus burn time.
