SAFETY FIRST!
When you use your Trangia Multifuel Burner (from now on called
TMFB), you’ll be handling highly flammable fuels. If used incorrectly, you will be
putting yourself and everything around you in danger. Make sure that you’ve
understood everything in this manual before using the stove. Try it out and get to know
it properly before you head out for adventure. Check that no fuel is leaking before
you light the stove. If you have spilled any fuel, the safest thing is to move the
stove. If you discover fuel leaking from any part of the stove, the leak must be taken
care of before the stove is used. Never use a stove that is leaking fuel.
The TMFB is designed for outdoor use only. A lit stove consumes oxygen and
gives off carbon monoxide. If you use the stove indoors in an unventilated area or in
a tent, you run the risk of falling victim to carbon monoxide poisoning. Make sure
that you never hold your face or any other part of your body over the stove. Also
make sure you keep your clothes away from the stove. Many materials used for
outdoor clothing, sleeping bags, etc. are highly flammable. Be very careful when
lighting a stove that has just been used. A hot burner can vaporize the fuel. The fuel
may ignite explosively. Allow the stove to cool properly before lighting it again. Never
leave the stove without supervision. Never leave children unattended near the stove.
Use TMFB only for cooking food and boiling water.
The TMFB is a multifuel stove. This means that you can use a number of different
liquid fuels, such as gasoline, diesel and kerosene. Unlike propane gas, these are
often easy to get hold of even in the most remote corners of the globe. They also
make your stove considerably more powerful when used during winter trips.
Preparing food on a multifuel stove using liquid fuel is slightly more complicated than
using a gas stove. First off, the fuel has to be pressurized in order to make the
stove as hot as possible.
The gas in a gas bottle is already pressurized when you buy it from the shop, but
the liquid fuel you put in your fuel bottle is not. Therefore, you have to pump up the
pressure in the bottle yourself. You also need to preheat the stove for a short time
using a squirt of fuel. Preheating involves heating up the burner to such an extent
that the fuel is vaporized when it passes through the burner’s nozzle. Vaporized fuel
burns efficiently with a blue flame and a hissing sound.
When your food is cooked and you want to shut off the stove, you turn the entire fuel
bottle to OFF position. This places the pump in a position whereby air comes out of the
bottle instead of fuel. When the fuel remaining in the hose has burned, the flame goes
out on its own and the pressure remaining in the bottle seeps out. If you turn off the
stove using the control valve only, fuel will remain in the hose and the bottle will stay
pressurized. This will cause a fuel spill when you dismantle the stove or transport
it in your pack.
The following pages show you how to use the stove, step-by-step.
1 - Fill the bottle with fuel and 1 screw on the pump.
Do not fill the fuel bottle to
the brim. It should only be filled about ¾ full. You have to leave some space
for the pump and the air that will be compressed when you pump up the
pressure.Check that the seal is positioned correctly in its groove before you
turn the pump into position. The seal must be flat and even all round. Screw
on the pump properly and wipe off any spilled fuel. Read more about
various fuels in the chapter on fuels.
WARNING
! Make sure that you stay well away from a lit stove or naked flame
when you are filling the bottle with fuel. Use only Trangia fuel bottles.
2- Fold out the fuel control valve and make sure that it’s in the off position.
It gets very hot under
the stove, so remember to place the stove on a firm base which cannot catch fire. Make sure that
the control valve is closed before pumping pressure into the bottle.
WARNING
! Do not place the stove on or near flammable materials. Avoid exposing the fuel
bottle to heat. The bottle may explode if it is exposed to heat.
3- Clear the nozzle in the burner.
All fuels contain contaminants that can block the nozzle in the
burner. The TMFB has a built-in clearing needle that is used to clear the nozzle with ease. Move
the multitool a few times directly beneath the burner’s base nut. The magnets on this tool force
the needle to move, thereby clearing the nozzle. Get into the habit of clearing the stove before
you start preparing food. This will reduce the risk of the nozzle in the burner getting blocked. See
the section entitled “ Maintenance & Cleaning and” if the stove functions poorly even though it
has been cleared using the multitool.
4- Connect the fuel hose to the pump’s quick connect
. Make
sure that the fuel feed valve is closed (turned fully
clockwise). Check the o-ring on the tip of the fuel hose.
Replace the o-ring if it is damaged, missing or worn. Fit the
fuel hose into the quick connect and make sure the bayonet
joint locks.
5- Pump up pressure in the fuel bottle.
The fuel in the bottle is
not pressurized, so you have to pump up pressure before the
stove can be lit and used. The fuel bottle can be placed in two
different positions, with the word ON or OFF on the top of the
pump. Place the bottle in the ON position when you want to use
the stove. If the fuel bottle is full (3/4 is full), you will need to
pump around 25 times. Pump about 40 times if the bottle is
half full or less. There must be firm resistance in the pump
when you reach the stove’s working pressure. Open the fuel
feed valve fully. The air pressure in the fuel bottle is crucial to
the heat of the stove. When preparing food, you may have to
do some more pumping in order to maintain maximum heat.
However, if you pump up too high a pressure the fuel flow will
be too great resulting in a yellow flame.
WARNING
! Make sure that no fuel leaking out before you light the stove. Never light a stove that
is leaking fuel.
6- Release a small amount of fuel for preheating.
The stove’s burner has to be hot to allow
the liquid fuel to vaporize at the nozzle and burn efficiently. Therefore, you have to preheat
the burner before you can start preparing food. This is done by first releasing a squirt of fuel
and allowing it to burn for a short time, heating up the nozzle in the burner. The preheating time
varies depending on what type of fuel you are using. For example, gasoline is vaporized more
readily than kerosene and requires less preheating. Preheating takes longer when it is cold
and if the stove is not protected from the wind. Start by opening the control valve for two
seconds. It is difficult to see how much fuel has run out onto the wick, but as time goes by you
will get a feel for this. Proceed with caution as you familiarize yourself with your stove.
WARNING
! Check for fuel leaks at the bottle, pump, hose and burner before lighting the stove.
7 - Light the fuel and wait until the flame has almost burned out.
Light the fuel at the wick using a
match or
lighter. The wick is the white pad in the center of the burner, in the bottom of the cup. This is
accessed via one of the holes in the cup. Of course, it is important to make sure that you
never hold your face or any other part of your body directly over the stove when you light it.
The fuel may ignite explosively. If the stove cannot be lit, you might not have released
enough fuel. If this is the case, repeat step 6.The fuel will burn with a yellow, flaring flame
and heat the burner. Wait a short time until the fuel has almost burned out and the flame
has become small.
WARNING
. Keep children away from the stove and never leave it without supervision.
8- Open the control valve again and adjust the flame until it turns blue and there is a hissing
sound.
Once the preheating flames are almost out, open the control valve again by about a quarter
turn. If the burner is hot enough, the fuel will vaporize and be ignited by the preheating
flame. The flame should then turn bluish and hiss gently after a short time. If the vaporized
fuel does not ignite, light it carefully with a match. A yellow, flaring flame means that the
burner is not hot enough or that you have opened the control valve too far. Start off
by closing the control a little. If the flame does not turn blue after 10-15 seconds,
the burner is not hot enough and you have to preheat the stove for a little 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. When the stove is burning as it should,
you can gradually open the control valve and make it hotter. Maximum heat is
attained 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. If the flame flares up and turns yellow, turn down the control slightly and
wait until the flame has turned blue again.
The burner is designed to burn best and give maximum heat with a pan in place. Once
the stove has been burning for a while, it may be a good idea to pump a couple of
times in order to maintain pressure in the bottle. Too little pressure in the bottle will
result in poor performance. Too much pressure will also lead to poor performance
and a yellow, flaring flame. With a little practice, you will learn how often and how
much to pump in order to maintain an effective flame.
WARNING
! Never move a hot stove or a stove that is in use.
9 - Shut off the stove by turning the bottle to OFF position.
If you want to avoid
annoying fuel spills when you
dismantle and transport the
stove, shut it off by turning the
fuel bottle to OFF position. OFF
will then be visible from above
on the pump. The fuel in the
hose will now burn up and the
remaining pressure in the bottle
will seep out. The flame will not
go out immediately, but will burn
for a few minutes depending on
which fuel you are using and
how open the control valve is.
To release the pressure in the fuel bottle faster, you can let the stove burn at full
throttle. It will take about 30-40 seconds for the flame to extinguish, and another 30
seconds for the remaining air to seep out. If you have shut down the stove by
closing the control valve only, you will have to release the pressure in the bottle by
way of the pump. This entails a great risk that fuel will spill on you and your
equipment. 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.
WARNING
! Be very careful when lighting a stove that has just been used. A hot burner
can vaporize the fuel. Vaporized fuel is very difficult to see. There is a risk that the fuel
will ignite explosively and you get burned.
10 - Let the stove cool down
. Allow the stove to cool properly before packing it. We
recommend that you leave the control valve open when you have shut off the stove by
turning the bottle to the OFF position. If you close the valve too tight when the stove is
hot, it may be hard to open the next time you use the
stove.
11- Remove the fuel hose.
Close the fuel feed valve
fully. Remove the fuel hose by releasing the bayonet
joint and then pull the hose out of the quick connect.
Sometimes there may be a little pressure remaining in
the bottle which seeps out when you disconnect the
quick connect. The same is true when you unscrew
the pump from the bottle. Turn your face away from
the stove to protect your eyes when separating the
quick connect. Be sure to apply the cover on the tip of
the fuel hose so dirt will not enter.
WARNING
! Never disconnect the hose immediately
after switching off the stove. Fuel may splash on the
hot burner and ignite.
FUELS
The TMFB is a burner designed to use petroleum-based fuels. Therefore, you cannot
use alcohol-based fuel. We recommend that you use chemically pure gasoline (not
automotive gasoline) or high-quality kerosene. Under no circumstances should you
handle fuel near a lit stove or in your tent. Use a funnel with a filter when filling the
bottle so as to avoid dirt and foreign bodies getting into the fuel. Never mix different
kinds of fuel. Empty the bottle entirely before putting in a different fuel.
GASOLINE -
It is often very easy to get hold of gasoline, even though the quality is
variable. Chemically pure gasoline is preferable. Ordinary automotive gasoline contains
