Fuel and performance
Jet 32 - LP Gas
• Primus cartridge LP Gas (propane/butane
mix) is the ideal fuel for the EtaPower MF
stove. The fuel is very easy to use, normally
requires no priming, and is efcient,
environmentally friendly and clean (no soot).
Minimum maintenance and cleaning are
required.
Jet 28 - Petrol/Gasoline
• Good quality industrial petroVgasoline, such
as PRIMUS PowerFuel, MSR® White Gas and
Coleman® Fuel give clean burning and leave
almost no deposits in the fuel system.
• Unleaded petroVgasoline is extremely
volatile and contains additives that leave more
deposits in the fuel system.
• Do NOT use leaded petrol/gasoline, because
of the health risks involved.
Jet 22 - Parafn/Kerosene
• Parafn/kerosene can be obtained
throughout the world, but burns with a smoky
ame, it is also more difcult to preheat and
requires regular cleaning.

IMPORTANT! When using a frying pan or
other pots than the EtaPower™ Pot, do not
use the wind screen (5)!
5.8 Place the burner (4) on the base and make
sure it is stable.
5.9 Twist the pot supports (7) into place and
make sure they are fully extended.
5.10 Pump 15-20 times, or pump more than
this if the fuel level is low.
5.11 Place the fuel bottle (laying down) on a
level base with the text “ON “ on the pump
facing upwards.
5.12 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.
5.13 Open the valve on the pump by turning
the knob anticlockwise for a short time. (3-4
seconds depending on which fuel you use.)
Liquid fuel will then ow towards the jet and
enter the burner Just opening it for a short
time will give sufcient fuel to start the stove.
More fuel than this gives a longer preheating
time and larger ames.
5.14 Check that no leaks occur in the
connections. If leaks are discovered, the stove
should not be lit.
5.15 Light the burner (at the pre heating
pad) (8) with a match, lighter or similar. Keep
your head and body away from the stove.
The liquid which has owed out previously
will now burn for about 45 seconds if it
is petroVgasoline, and 90 seconds if it is
parafn/ 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 ame is yellow and relatively large, the
pump’s valve should be closed and preheating
allowed to continue for a while longer. If the
ame is small and relatively blue, the stove is
ready for use.
5.16 When the stove is burning, it should be
kept level and not moved around. If the stove
is moved, or is not sufciently hot, it can are
up.
5.17 Ensure that inammable material is kept
at a safe distance. Distance to ceiling should
be at least 1250 mm and to well at least 1250
mm, OTHERWISE it can catch re!
5.18 To close down the appliance and empty
the fuel system. Turn the fuel bottle 180°
so that the “OFF’ text on the fuel pump is
pointing upwards. When the ame 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.
5.19 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 control knob (2) completely and
unscrew the LP Gas cartridge (3).
6.3 Squeeze the spring-loaded burner holder
(10) and remove the burner.
6.4 Loosen the clamp screw (14) on the
injector tube (12) and remove the preheating
coil (11).
6.5 Unscrew the jet (9) with the multitool or an
8mm open-end wrench.
6.6 Clean the jet using the cleaning wire on the
multitool. 6.7 Mount the jet on the pipe and
make it leak-proof by tightening it carefully. Do
not tighten too hard. Check that it is leak-proof
with soapy water or similar.
6.8 Place the preheating coil in the injector
tube (12), fasten it with the clamp screw (14),
and reattach the burner holder (10).
6.9 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).
6.10 Unscrew the hose from the fuel
connection with the multitool. Pull the
deaning wire out using the multitool. Pull the
wire backwards and forwards until the fuel
connection is clean. Rush 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 ush 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 ame, pilot ame 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.
6.11 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 arid/or check the O-ring on
the back valve (18). Clean if 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 efciency 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 as to how the (maintained) power can
be increased.
Possible reasons and measures if the
appliance burns with an unstable, yellow
ame:
- Insufcient preheating (see item 5).
- The jet is blocked (clean regularly as
described under item 8)
- Preheating for too short a period
- The incorrect jet is mounted on the appliance
(check and replace jet)
- Excess pressure in the fuel bottle
- Increasing from low power to high power too
quickly
- The appliance is not protected against wind.
A collapsible wind screen should always
be used during windy conditions. This is
especially important with winter use.
