CHOOSING A FUEL
Liquid fuels work considerably more effectively than gas in cold conditions. The pressure in gas
tubes is impaired at just a few degrees below freezing. Keep in mind that some poor qualities of
kerosene and diesel will solidify in the cold. If you are not sure what will happen, you can place a
bottle with the fuel in your freezer and see what happens.
PARTS SUSCEPTIBLE TO COLD
The quick connect and O-rings are the stove parts most susceptible to cold. The O-rings may stiffen
and crack when the temperature falls below -20 °C (-4 °F). Check them before leaving on your trip,
and replace them if they look worn.
EFFICIENT FOOD PREPARATION
When the weather is cold, it is of course even more important to use a wind screen and a lid on your
pan when cooking: this considerably reduces the amount of time/fuel needed to heat your food. With
our Optimus Terra set of cooking pans, you can also keep your food hot once it has been taken off
the stove.
OPTIMUS NOVA ON SNOW
When you use your Optimus Nova on snow, it is important that you place a non-flammable base
beneath the stove so that it will not sink into the snow while you cook. Set up a surface on which you
can place the stove, bottle and pans, and pack the snow down hard so as to form a firm base.
MELTING SNOW
You can melt snow more quickly if you start with a little water in the bottom of the pan. It takes longer
to melt ice than it does to melt snow.
WASHING DISHES IN WINTER
Washing up pans is always a little more complicated in winter. Use Teflon coated pans and leave the
leftover food to freeze before scraping it out with snow. You can also dissolve grease in the pans
using cooking oil and then wiping it out. It is a good idea to boil water for dishwashing right after
cooking in order to save fuel.
OPTIMUS NOVA AT ALTITUDE (MORE THAN 4,000 METERS)
The Optimus Nova is one of the best stoves on the market for use in extreme situations. Among other
things, this stove has been used successfully in the Himalayas at altitudes of 7,400 meters. However,
using multifuel stoves with liquid fuels at altitudes in excess of 4,000 meters can cause problems.
Burning may be uneven due to the fact that there is less oxygen in the atmosphere. Choose your fuel
carefully and make sure that there is free access to air around the stove. Gasoline and white gasoline
is sometimes difficult to use at high altitude since it evaporates easily already in its liquid form.
Normally good quality kerosene performs well at high altitude.
