INSTRUCTIONS FOR USE
IMPORTANT: Read these instructions carefully before
connecting the appliance to the gas cartridge or
liquid fuel bottle. Study the instructions at regular
intervals to remain familiar with the operation of
the appliance and keep them for future reference.
Failure to follow these instructions may
result in serious injury or death!
CAUTION: This appliance consumes air (oxygen) and
produces carbon dioxid. To avoid danger to life,
NEVER light or use the appliance in an unventilated
space, indoors, in a tent, in a vehicle or in any other
enclosed area.
Use outdoors only!
NEVER cover the stove (gas cartridge or liquid fuel bottle)
with a wind shield, rocks or similar which may cause
overheating or damage to the stove and cartridge/
fuel bottle. Overheating a gas cartridge or liquid fuel
bottle in this way is highly dangerous.
FUELS AND PERFORMANCE
Jet 45 (0.45 mm)
•
Primus cartridge gas (propane/butane/isobutane
mix) is the ideal fuel for the OmniFuel 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 (0.37 mm)
•
High quality white gas (PRIMUS PowerFuel, MSR®
White Gas/Coleman® Fuel) affords clean combus-
tion and leaves practically no deposits in the fuel
system.
•
Vehicle petrol should be used only in exceptional
cases since it contains additives which are harmful
to your health and also leave deposits in the fuel
system.
•
For health reasons, leaded petrol should never be
used.
Jet 28 (0.28mm)
•
Although kerosene is available worldwide, it creates
more soot, is more difficult to prime and necessi-
tates frequent cleaning.
•
Diesel oil may be used if no other fuel is available.
Diesel oil burns with a very sooty flame, takes a long
time to preheat and necessitates frequent cleaning.

4.
ASSEMBLING AND OPERATING THE
APPLIANCE WITH A GAS CARTRIDGE (Figs.
2 and 4)
4.1
It is absolutely essential that the fuel line
be completely clear of liquid fuel when
cartridge gas is used, otherwise a dan-
gerously high flame will result! (See 6.8.7
for instructions on how to drain the fuel
system.) Also ensure that a 0.45 mm jet is
installed.
4.2
Ensure that the shut-off valve (2) and gas control (5)
are fully closed (by turning the knob fully clockwise).
4.3
Keep the cartridge (3) upright when fitting it to the
valve.
4.4
Place the valve squarely on top of the cartridge (as
shown in Fig .2).
4.5
Screw the cartridge carefully into the valve until it
meets the O-ring, taking care not to cross-thread
the cartridge. Hand-tighten only. Do not over-
tighten, otherwise the cartridge valve may
be damaged.
4.6
Ensure that the gas seal is tight. Carry out checks
outdoors. NEVER use a naked flame to check for
leaks. Apply warm, soapy water to the joints and
connections, and observe for leaks in the form of
bubbles around the suspect area. If in doubt, or if
an escape of gas can be heard or smelled, do not
attempt to light the appliance. Unscrew the car-
tridge and contact your local dealer.
4.7
Swing the legs (pan supports) (12) into position in
the wind shield (11).
4.8
The stove is now ready for use.
4.9
Always place the appliance on a steady surface.
Ensure that the hose is fully extended, and that it is
run straight between the cartridge and stove. Keep
the cartridge clear of the heat of the appliance.
4.10 First turn the shut-off valve (2), then the gas control
(5) counterclockwise and light the burner (4) imme-
diately.
4.11 Adjust the flame using the gas control (5) or shut-off
valve (2).
4.12 After lighting, keep the appliance upright and do not
move it around. A high flame may occur if the appli-
ance has not been preheated fully or if it is moved
without care.
4.13 After use, first close the shut-off valve (2). When the
flame is extinguished, also close the gas control (5).
4.14 A minimum clearance must be maintained with
flammable materials. The minimum permissible
clearance between the appliance and ceiling, and
between the appliance and the nearest wall, is
1,250 mm. These minimum clearances must
be observed to prevent a fire hazard.
5.
CHANGING THE CARTRIDGE
5.1
Close the shut-off valve (2) and gas control (5)
fully. Ensure that the flame is extinguished and
that there is no other flame source in the vicinity.
Change the cartridge outdoors away from other
people. Unscrew the cartridge from the valve and
replace the O-ring seal if cracked or worn. Avoid
cross-threading by placing the valve squarely on
the cartridge thread, and hand-tighten only as de-
scribed in section 4.
6.
ASSEMBLING AND OPERATING THE
APPLIANCE WITH LIQUID FUEL (Figs. 3 and
4 )
6.1
The appliance is delivered with three jets. Jet 45 is
for cartridge gas, jet 37 for white gas and unleaded
petrol, and jet 28 for kerosene, diesel oil and similar
fuels. Ensure that the correct jet is installed.
6.2
Fill a Primus fuel bottle to the filling mark with liquid
fuel. NOTE! Never overfill the bottle!
6.3
Ensure that the shut-off valve (2) and gas control (5)
are fully closed (by turning the knob fully clockwise).
6.4
Screw the pump (21) into the fuel bottle (20).
6.5
Screw the fuel pump swivel coupling (22) care-
fully into the valve until it meets the control valve
O-ring (as shown in Fig. 3). Be careful not to
cross-thread the connection. Hand-tighten
only – overtightening will damage the
connection.
6.6
Swing the legs (pan supports) (12) into position in
the wind shield (11).
6.7
Pump about 20 full strokes, or more if the fuel
level is below the filling mark on the fuel bottle.
6.8
Place the fuel bottle on a firm, level surface with
the text 'ON' the fuel pump facing upward.
6.9
Always place the appliance on a steady surface.
Ensure at all times that the hose between the
cartridge and stove is straight, and cannot come
in contact with the flame or hot gases. Ensure
that the hose is not twisted or subject
to abrasion. Keep the fuel bottle away
from the heat of the appliance.
6.10 First open the shut-off valve (2) then open the
gas control (5) by turning it a half turn counter-
clockwise. Allow fuel to spray from the jet for
about 2 seconds before closing the control. If
using kerosene or diesel, or if the weather is cold
and windy, more fuel will be required for pre-
heating. In this case, allow fuel to escape for 4-6
seconds.
6.11 Check for leaks at the shut-off valve, gas control,
fuel pump, jet, fuel hose and fuel line. DO NOT
USE THE APPLIANCE IF LEAKS ARE
PRESENT.
6.12 Light the priming pad. DO NOT LEAN OVER
THE APPLIANCE WITH YOUR HEAD OR
BODY! The priming pad will now burn for about
40 seconds if white gas is used, and for longer
if kerosene or diesel is used or if the ambient
temperature is low. Open the gas control slowly
(by turning counterclockwise) when the fuel in
the priming pad begins to run out, but before the
flame has expired completely. If the appliance
burns with a yellow or an unstable flame, priming
has been insufficient. Try closing the gas control
somewhat until a steady, blue flame is estab-
lished and allow the device to burn at low power
for a while to heat up. If the stove still cannot be
operated at full power, the only course is to turn
it off, allow it to cool fully and repeat the priming
procedure for a longer period using more prim-
ing fuel. Remember also that the stove must be
shielded from the wind during this procedure.
6.13 After lighting, keep the appliance upright and do
not move it around. A high flame may occur if
the appliance has not been preheated fully or if it
is moved without care.
6.14 A minimum clearance must be maintained with
flammable materials. The minimum permissible
clearance between the appliance and ceiling,
and between the appliance and the nearest wall,
is 1250 mm (48 inches). These minimum
clearances must be observed to prevent
a fire hazard.
6.15 To turn the appliance off and empty the fuel sys-
tem, turn the fuel bottle over so that the 'OFF' on
the fuel pump is facing upward. When the flame
has been extinguished and air is flowing through
the jet, close the shut-off valve (2) by turning the
knob fully counterclockwise. Note! This proce-
dure will take about 1 minute. Also close the gas
control (5) when the appliance has been turned
off. Allow the appliance to cool before disassem-
bling it.
6.16 NEVER relight a hot appliance. Hot parts may
vaporise the liquid fuel and cause a dangerous
'fireball'.
7.
MAINTENANCE
7.1
When using liquid fuels, the jet should be
cleaned regularly for optimum, trouble-free oper-
ation. If the appliance is used for long periods or
with poor quality fuel, the control spindle (30) will
require cleaning.
7.2
Cleaning the jet
Close the shut-off valve (2) and gas control (5),
and unscrew the cartridge or fuel bottle.
7.3
The jet (10) can be cleaned in situ or when un-
screwed from the appliance.
7.4
Clean the jet using the cleaning needle (26) sup-
plied with the appliance.
7.5
Refit the jet and screw it home securely to ensure
a good seal. Fit a Primus cartridge for added
safety and check the joint with warm soapy
water. The appearance of bubbles indicates that
the joint is not sufficiently tight.
7.6
Cleaning of control spindle
Unscrew the locknut (31) using the multi-tool.
Unscrew the spindle. Carefully clean the three
grooves at the tip of the spindle, for example
using a fingernail. Take care not to damage the
spindle threads. Ensure that the spindle O-ring
is intact and check its tightness following reas-
