Why does my Nova stove not work right above an elevation of about 4,000 meters?

The use of a stove above 4,000 meters can cause a number of problems.

Combustion can function irregularly due to the low oxygen supply. Thus, select your fuel carefully and always make sure there is enough air around the stove during use. The use of liquid fuel and white gas at higher altitudes can be a problem since these fuels evaporate while still in their liquid form. Good quality liquid petroleum is normally suitable for use above 4,000 meters.
