I spent the spring of 1995 on the north side of
Mount Everest. Some of my time was spent at the tented village on
the North Col, at an altitude of 7000 metres. One evening, I
prepared a meal inside my tent with three other climbers, as the
weather outside was so ferocious that cooking al fresco was
impossible. Suddenly, the stove – which was positioned in the centre
of the tent – turned into a flame-thrower and belched out four great
tongues of fire. Miraculously, none of us were set ablaze, and just
as the flames began licking the walls of the tent they retreated
into the burner. The experience taught me a number of lessons, not
least the importance of adhering to safety drills: these days I
always cook outside or in the open porch of the tent, whatever the
weather.
Safe cooking starts with a decent stove, and this
leaflet aims to ensure that you make the correct choice. There are
words of advice too if you wish to camp with a lantern. However, for
guidance on individual models, chat to a member of Cotswold’s staff,
who are well placed to describe the differences between the various
designs available.

pots & utensils | |
types of burner |
|
Pots are generally made from one or sometimes two
key materials: steel, aluminium and titanium. Titanium is the
lightest material and is stronger than aluminium. Aluminium finds
favour with backpackers who want lightweight gear but without the
steep financial penalty associated with titanium. Aluminium is also
an excellent conductor of heat. Steel is the heaviest of the three,
and in comparison to aluminium it is a poor conductor. But steel is
very durable, making it a popular choice on expeditions and group
treks. Non-stick pans and pots are also available. (Just as in the
kitchen, non-stick requires the use of plastic utensils, the
toughest of which are made from inexpensive Lexan.)
Whatever
pots you buy, do make sure they have close-fitting lids. Placing a
lid on a pan of water is the most effective method of decreasing
boiling time. The best lids also double up as frying pans. At high
altitudes, pressure cookers have a useful role to play; most
Himalayan base camps are staffed by cooks who use their pressure
cookers in order to turn out vast quantities of fluffy rice for
hungry trekkers, climbers and porters.
A decent pot gripper
is vital; make sure that yours is strong enough to hold your pan
when it is full of water and food: trying to drain pasta with a
flimsy gripper can result in dinner being eaten off the ground.

The beating heart of any stove is the burner, and
to a great extent this is what your money is buying. All burners
fall into one of two categories: pressurised and
unpressurised. Pressurised stoves require pressure of one
sort or another in order to function. For example, stoves which run
on gas require butane, propane, or a mixture of the two. These fuels
are supplied in sealed and pressurised metal cannisters. The largest
gas bottles (which are used in caravans and on gas-powered
barbecues) can be re-filled by trained staff; the smaller bottles
favoured by campers and mountaineers can only be used
once. By contrast, liquid fuel burners which run on petrol
and paraffin (kerosene) can be topped up by the user. Consequently,
the specially engineered tanks which these fuels are dispensed into
need to be manually pressurised by way of an integral
pump. Unpressurised stoves, that run on either solid fuel or
liquids such as methylated spirits and ethanol, can be ignited
without any pre-amble. Unpressurised stoves, and burners
fuelled by pressurised bottled gas, need little in the way of
attention. Not so pressurised liquid fuel burners, which require
regular maintenance. The decision as to whether to opt for a
pressurised or un-pressurised stove depends largely upon where you
plan to use your stove. At low altitudes, unpressurised stoves are a
superb hassle-free option. But in cooking situations where an
infinitely adjustable flame is required, at altitudes greater than a
couple of thousand metres, or when a real burst of concentrated heat
is essential for snow melting, then a pressurised stove is
essential.

Radiator-style attachments are available which
fit on all pots. Wrapped around the exterior of the pan, and with
the lower lip extending below the base of the pot in order to catch
the heat that would otherwise escape around the sides, this type of
so-called ‘heat exchanger’ can reduce the amount of time it takes to
boil a pan of water and therefore decrease the amount of fuel
required on your trip.
When camping in winter conditions, it
is important to insulate your stove from the snow. Otherwise, the
whole assembly will melt into the ice and finally be snuffed out or
simply fall over. Anything from a proprietary stove support (made
from aluminium with holes drilled throughout to reduce weight) to a
metal snow shovel can be used to prevent the stove from sinking into
the surface of the snow. Or you can make your own from a thin sheet
of plywood, although you will need to take care not to set it
alight.
Ultralight foil windshields are available which fit
around all types of camping stove. These prevent the wind from
snuffing out the burner whilst it is alight, and also help to
concentrate heat around the pan. When used in conjunction with a
heat exchanger, these windshields can greatly improve the
performance of any stove.

lanterns | |
fuel types &
availability |
|
Lanterns have always enjoyed a steady stream of
support from the family camping and caravan enthusiasts. Now they
are being made small and light enough for backpackers
too.
The main choices to be made here revolve around the
amount of light you want, for how long, and from what type of fuel
supply. Battery operated lanterns are the safest type, and can be
used inside tents without any real risk of fire. By contrast,
lanterns fuelled by gas or liquid fuel need to be intelligently
sited away from flammable materials such as flysheets and inner
tents. If you do decide to opt for a bottled gas or liquid fuel
lantern then it’s probably a good idea to choose one that runs on
the same fuel as your stove. That way, if you start to run low on
fuel for cooking, you can siphon some from your lantern.
Some
lanterns come with a glass mantle, which is likely to shatter if
subjected to any sort of stress. This sort of design is not ideal if
you plan to carry your lantern inside a rucksack all day long. Some
lanterns are supplied in durable containers, but even so you may
want to line the housing with some squares of foam in order to
reduce the chance of damage to fragile parts.

safety
advice | |
|
Stoves and lanterns are probably the most
hazardous products in your arsenal of outdoor equipment. So it’s
important to follow all instructions supplied by the manufacturer to
the letter. It also makes sense to practice using new products
before setting off on a trip.
A lot of outdoor gear –
including tents, sleeping bags and fleece clothing – is flammable.
Constant attention needs to be paid to stoves and lanterns when they
are alight to ensure that no combustible materials come into contact
with these devices. Particular vigilance is required during the
lighting process when flaring can occur. This can result in flames
being shot several feet into the air. For this reason, ignition
should always take place outside, even if the stove is subsequently
placed under an awning in order to cook during periods of bad
weather. Re-filling fuel tanks also requires attention to detail.
Critically, stoves must be fully extinguished before re-fuelling
commences. This might sound obvious, but with some stoves – most
notably unpressurised liquid fuel models – it is physically possible
to re-fill the burner whilst the stove is alight. This is an
extremely dangerous thing to do.
Eventually, parts on your
stove will wear out and need replacing. Of course, this might happen
when you are on a trip. Consequently, it is worth purchasing a small
pack of spare parts so that repairs can be made in the field.

In addition to ensuring that your stove cannot
scorch the ground it is placed upon, it’s worth taking a moment to
think about the fuel you are using, as well as the safe disposal of
liquid or canisters at the end of your trip. It is common in
some countries for fuel to be contaminated; for this reason it is a
good idea to carry a fuel filter in order to minimise the number of
agents that could clog up the stove’s fuel line. It is
illegal to carry flammable liquid on aircraft, so consider
distributing any remaining liquid fuel to your trekking staff or
local families, rather than pouring the toxic liquid away and
contaminating the environment and water sources. If your
stove runs on pressurised gas cannisters, then you will need to
leave room in your rucksack to carry out empty cylinders at the end
of your trip. Puncture-style metal cannisters can be recycled when
empty as the hole in the top means that there is no chance of gas
remaining inside. However, it is possible that pockets of gas can
remain in cylinders with self-sealing valves. So before placing this
type of canister out with your regular rubbish, keep the burner
alight until the stove self-extinguishes in order to minimise the
chance of any fuel remaining inside. As with liquid fuel, it is
illegal to take gas canisters on an aircraft.

Of course, there’s more – much more – to a stove
than the burner and the fuel used to operate it. Some of the other
features you will probably want to consider before purchasing
include:
• automatic ignition This type
of gadget removes the need to hold a flame to the stove in order to
ignite the burner. Handy if you forget to pack a lighter or matches.
• pan supports These are essential in
order to keep your pot from tipping over. Some stoves have fold-out
supports which reduce the bulk of the stove when packed in your
rucksack. Ultralight stoves may struggle with anything larger than a
1.5 litre pan, so it is worth considering what volume of food or
water you want to heat at any one time.
• fuel
tank Most pressurised liquid fuel stoves either sport an
internal fuel tank, or utilise the separate fuel bottle as the
external tank. Given that for anything more than a weekend trip an
extra fuel bottle is pretty much essential, being able to use that
bottle as your tank can result in a significant weight saving. Such
a system also allows you to take a smaller bottle for weeklong
trips, and several larger containers for extended adventures.
However, it is critical that you only use the brand of fuel bottle
recommended by the stove manufacturer, otherwise the seal between
stove and bottle may fail with potentially disastrous results.
• fuel line Some stoves allow
pressurised gas cartridges to be screwed onto the base of the
burner, whilst others connect via a hose. The advantage of the
former is that there is less to go wrong (some rubberised fuel lines
can be prone to wear and tear). The advantage of the hose concept is
that this type of stove is likely to be supplied with fold-out legs
that are larger – and therefore more stable – than the diameter of
the canister.
• fuel pre-heater In cold
conditions, fuel needs to be warmed before it can be ignited by the
burner. So some stoves designed for expedition use incorporate a
fuel line that passes over the burner, ensuring that fuel is primed
prior to coming into contact with the flame. (It is worth noting
that in very low temperatures, a dollop of burning paste may need to
be spread around the burner in order to allow ignition to commence.)
