FUEL AND PERFORMANCE
Jet 42 - LP gas
• P rimus cartridge gas (propane/butane mix) is the
ideal fuel for the Gravity MF stove. The fuel is very
easy to use, normally requires no priming, and is
efficient, environmentally friendly and clean (no soot).
Minimum maintenance and cleaning are required.
Jet 37 - Petrol/Gasoline
• G ood quality industrial petrol/gasoline, such
as PRIMUS PowerFuel, MSR® White Gas and
Coleman® Fuel give clean burning and leave almost
no deposits in the fuel system.
• U nleaded petrol/gasoline is extremely volatile and
contains additives that leave more deposits in the fuel
system.
• D o NOT use leaded petrol/gasoline, because of the
health risks involved.
Jet 26 - Paraffin/Kerosene
• P araffin/kerosene can be obtained throughout the
world, but burns with a smoky flame, it is also more
difficult to preheat and requires regular cleaning.

2. ADVICE FOR SAFE USE
2.1 Ensure that the appliance and pump seals (1) are in
place and in good condition before fitting the LP gas
cartridge or liquid fuel bottle.
2.2 This appliance is intended for use outdoors only. To
avoid extreme danger, do NOT use this appliance in
unventilated space, indoors, in a tent, in a vehicle or
other enclosed space.
2.3 Put the appliance on the accompanying ground
protection (5) and as flat as possible.
2.4 Make sure that no inflammable objects are in the
vicinity, as explained under item 4.12
2.5 Always fit or replace the LP gas cartridge/liquid fuel
bottle in a safe place. This should be done outside
only, away from possible sources of ignition, such as
naked flames, pilot lights and electric fires, and well
away from other people.
2.6 If there is leakage from the appliance (smell of LP gas,
petrol/gasoline, etc.), it should immediately be put in
a well ventilated place outdoors, not in the vicinity of a
source of ignition, where the leak can be investigated
and stopped. Checking for leaks may only be carried
out outdoors. Checking for leaks must never be made
with a naked flame. Use soapy water or similar.
2.7 Never use an appliance with damaged or worn seals,
nor a leaking, damaged or badly working appliance.
2.8 Never leave a lit appliance out of sight.
2.9 Make sure that saucepans do not boil dry.
3. HANDLING THE APPLIANCE
3.1 Do not touch the heated parts of the appliance during
use or directly after use.
3.2 Storage: Always unscrew the fuel bottle from the
appliance when it is not being used. Store the
container in a dry, safe place, where there are no
sources of heat. Avoid solar radiation.
3.3 Do not misuse the appliance or use it for other
purposes than that for which it is intended.
3.4 Handle the appliance carefully. Do not drop it.
4. ASSEMBLY AND USE OF THE APPLIANCE WITH
LP GAS CARTRIDGES
4.1 Make sure that the right jet is used for the selected
fuel.
4.2 Make sure that the valve (2) is closed (maximum
clockwise).
4.3 Keep the LP gas cartridge (3) upright when connecting
it to the valve.
4.4 Connect the valve to the LP gas cartridge carefully.
Make sure the screws are not cross-threaded.
Tighten until the O-ring of the valve meets the LP gas
cartridge. Only tighten by hand.
4.5 Ensure that the connection is leak-proof. Check for
any leaks outdoors. Use soapy water or similar. Never
use a naked flame when checking for leaks. If using
soapy water, any leak will show itself as small bubbles
at the point of leakage. If you are unsure, or can hear
or smell gas, never light the appliance. Unscrew the LP
gas cartridge and contact your local Primus retailer.
4.6 Fold out the four legs of the stove (4).
4.7 The stove is now ready for use.
4.8 Put the accompanying ground protection (5) on as
level a surface as possible under the stove. Ensure
that the hose is fully pulled out towards the LP gas
cartridge. Keep the LP gas cartridge away from heat
that radiates from the stove when in use.
4.9 Turn the valve knob (2) anticlockwise, and light the
stove. The flame can be fine-tuned by turning the valve
knob (2).
4.10 When the stove is burning it should be kept as level as
possible and must not be moved around. Moving the
stove while in use can cause it to flare up.
4.11 Ensure that the stove is turned off completely after use
by turning the valve knob clockwise as far as it will go.
There will be some delay between turning the valve off
and the burner going out.
4.12 The distance to inflammable material in ceiling and
walls must be at least 1250 mm, OTHERWISE they
can catch fire.
5. ASSEMBLY AND USE OF THE APPLIANCE WITH
LIQUID FUEL
5.1 Make sure that the right jet is used for the selected
fuel.
5.2 Fill a Primus fuel bottle up to the level line with the
selected liquid fuel. NB! Never fill above the level line.
Make sure that the valve knob (2) is tightened so that
the valve is closed (maximum clockwise).
5.3 Connect the pump to the fuel bottle. Make sure the
screws are not cross-threaded. Tighten.
5.4 Screw the fuel pump swivel coupling carefully into the
valve until it meets the control valve O-ring. Be careful
not to cross-thread the connection. Hand-tighten only
– overtightening will damage the connection.
5.5 Open out the four legs of the stove (4).
5.6 Pump 15-20 times, or pump more than this if the fuel
level is low.
5.7 Put the fuel bottle on a level base with the text "ON" on
the pump facing upwards.
5.8 The appliance should always be standing on a level
surface with the hose pulled out towards the fuel
bottle. Keep the fuel bottle away from heat.
5.9 Open the valve on the pump by turning the knob
anticlockwise for a short time. Liquid fuel will then flow
towards the jet and enter the burner. Just opening it for
a short time will give sufficient fuel to start the stove.
More fuel than this gives a longer preheating time.
5.10 Check that no leaks occur in the connections. If leaks
are discovered, the stove should not be lit.
5.11 Light the burner with a match, lighter or similar.
Keep your head and body away from the stove. The
liquid which has flowed out previously will now burn
for about 45 seconds if it is petrol/gasoline, and 90
seconds if it is paraffin/kerosene. During this so-called
preheating period, the liquid vaporises, and at the end
of this period, a crackling noise can be heard. Then
the pump valve should be opened slowly by turning
the knob anticlockwise. If the flame is yellow and
relatively large, the pump's valve should be closed and
preheating allowed to continue for a while longer. If the
flame is small and relatively blue, the stove is ready for
use.
5.12 When the stove is burning, it should be kept level and
not moved around. If the stove is moved, or is not
sufficiently hot, it can flare up.
5.13 Ensure that inflammable material is kept at a safe
distance. Distance to ceiling should be at least 1250
mm and to wall at least 1250 mm, OTHERWISE it
can catch fire!
5.14 To close down the appliance and empty the fuel
system. Turn the fuel bottle 180º so that the "OFF" text
on the fuel pump is pointing upwards. When the flame
has gone out and only air is going through the jet,
close the valve (by turning the control knob clockwise
as far as it will go). Note: This procedure will take
about 1 minute. Let the appliance cool down before
taking it apart.
5.15 Do NOT relight a hot appliance.
6. MAINTENANCE
6.1 When using liquid fuel, the jet must be cleaned
regularly for optimal, problem-free use. If the appliance
is used for a long period of time, or with inferior fuel,
the fuel connections will need to be cleaned.
6.2 Cleaning the jet
Close the shut-off valve (2) and unscrew the cartridge
(3) or fuel bottle (20).
6.3 Loosen the clamp screw (14) on the injector tube (12)
and remove the preheating coil (11).
6.4 Unscrew the jet (9) with the multitool or an 8 mm
open-end wrench.
6.5 Clean the jet using the cleaning wire on the multitool.
6.6 Assemble the jet (9) on the pipe and seal it by pulling
carefully. Do not pull too hard. Check that it does not
leak with soapy water or similar.
6.7 Re-assemble all parts.
6.8 Cleaning the fuel connection
A cleaning wire (16) is delivered with the appliance for
this purpose. The wire is stored in the fuel pipe (11).
6.9 Unscrew the hose from the fuel connection with the
multitool. Pull the cleaning wire out using the multitool.
Pull the wire backwards and forwards until the fuel
connection is clean. Flush the fuel connection with the
jet disassembled, and connect the fuel pump/bottle to
the appliance. Pressurise the fuel bottle and open the
control valve and flush half a cupful of fuel through the
fuel connection. Warning: This must not be carried
out in the vicinity of a source of ignition such as open
flame, pilot flame or electric heater. Do not spill fuel.
Assemble the hose and screw it down so that the
connection is leak proof. Do not tighten too much. For
extra safety do this outdoors. Check that there are no
leaks using soapy water or similar. Assemble the stove
in accordance with Item 6.7.
6.10 Fuel pump
If the pump does not pressurise the fuel bottle, stretch
the leather gasket (17) slightly and oil it with Primus
leather oil (saliva or other mineral-based oil). Unscrew
the pump rod and pull it out. Rub the oil into the
leather gasket until it is soft and pliable. If the pump
does not pressurise the fuel bottle despite this, replace
the leather gasket and/or check the O-ring on the
back valve (18). Clean as necessary.
7. Checks and maintenance
7.1 Always make sure that seals are correctly located and
in good condition. This should be checked every time
the appliance is assembled. Replace seals if they are
damaged or worn. New seals can be purchased from
you nearest Primus retailer.
8. ADVICE AND TROUBLESHOOTING
8.1 The use of LP gas in cold weather is affected by a
number of factors which can be remedied with a
number of measures.
Factors that affect the efficiency of the stove:
- The mixture of gas in the LP gas cartridge (propane/
isobutane/butane)
- The quantity of LP gas in the cartridge
- The surrounding temperature
- The temperature of the LP gas cartridge
Measures which improve function during cold weather:
- Warm the LP gas cartridge with your hands or under
clothing.
8.2 When liquid fuel is used in connection with low
power (boiling), the fuel bottle should be used with
low pressure by only pumping the fuel pump once or
twice. Important information is given below regarding
the power of stoves used with fuel bottles and advice
