6. USe STOve TO COOK

1. 

once the preheating flames are almost out, open the control valve again by a quarter turn. 
if the burner is hot enough, vaporization of the fuel takes place. the flame ring should then 
be complete, turn blue and hiss gently. 

FigUre [12]

 

if the vaporized fuel does not ignite, 

light it carefully with a match. 

2. 

a yellow, flaring flame means that the burner is not hot enough or that the control valve is 
opened too far. to avoid that, close the control valve slightly. if the flame does not turn 
blue after 10 - 15 seconds, the burner is not hot enough and you have to preheat the stove 
longer. in this case, close the control valve one more time, wait until the flames are almost 
out and then open the control valve again.

3.

  When the stove is properly burning, you can gradually open the control valve and increase 

power. Maximum power is reached when the control valve has been opened by about two 
turns. if you open it by more than two turns, you will use up more fuel without making the 
stove any hotter. 

4. 

if the flame flares up and turns yellow, turn down the control valve slightly and wait until 
the flame has turned blue again.

5.

  once the stove is burning for a while, maintain pressure in the fuel bottle with 

  additional pumpstrokes. too little pressure will result in poor performance. too much 

pressure will lead to a yellow, flaring flame. With some practice, you will learn how often to 
pump in order to maintain an effective flame.

 

danger

risk of burning due to incorrect handling 

Make sure to arrange the pump head and the control spindle before you in a safe and
ergonomic way

, so that you are not getting too close to the flame during

operation of the stove.

7. TUrn OFF, COOL and PaCK STOve

1. 

turn the fuel bottle to the off position while the flame is burning. off will then be visible 
from above on the pump.

 

FigUre [14]

 

the fuel in the hose will now burn up and the 

remaining pressure in the bottle will be released. 

2.

  the flame will not go out immediately, but will burn for a few minutes depending on which 

fuel you are using and how far the control valve is open.

3. 

if the stove is to be used again without being moved, you can switch off the stove using 
the control valve. allow the stove to cool properly before lighting it again.

4.

  allow stove to cool for at least 10 minutes before packing it.
