  • Page 5: Safety First

    SAFETY Safety First Yes, I know, everyone who buys a new stove or a similar product, will play around with it at first – they will use the stove before they read the manual. If you do this with a toaster, you may just burn yourself, but with a stove it’s different –...

    We believed they should be interesting, written comprehensively and be practical and useful. We hope you find this supplement helpful in getting the best out of your Primus stove. The Primus Team with Till Gottbrath ©Primus AB. All rights reserved.

    Special gas mixtures like The jet nipple marked 28 (= 0.28 mm) is for all other liquid fuels. Primus Liquid Gas works well, even Please check that the right jet nipple has been at high altitudes. There is only one installed.

    FUEL Other disadvantages are the varying qualities and types of petrol. There is a so called catalytic gas / white gas (called lighter fluid gas at the chemist’s drugstore, stove gas in How does a stove work? the outdoor shop, or Unlike a paraffin lamp with a wick, a stove does not burn liquid fuel, but only gas.
  • Page 9 The energy balance of alcohol is good enough for a solid beer belly but as stove fuel it will try the patience of a saint... The cooking performance index of spirits (see table on page 50) is scarcely half that of Primus Liquid Gas.

    At the moment, however, there is no sealing compound that is re- sistant against both alcohol and benzole (components of gas or paraffin). Primus is doing research on a new material, but right now it doesn’t exist. So for now: hands off spirits! Please notice the table “Fuel in comparison”...

    STOVE ASSEMBLY To repeat what we said earlier: Did you read this booklet from start to finish? Are you outdoors? Have you found a place where the stove can be placed safely? Did you make sure that the control valve is turned off (= turned fully clockwise)? Did you install the correct jet nipple for the fuel you are using?
  • Page 12 TURNING THE STOVE ON 1 Cooking with gas (only for MFS) Gas is my favourite fuel: just arrange the stove, hold a burning lighter or match over the burner, open control valve on hose swivel connection , and there it goes! 2 Liquid fuel Fill the bottle to the fill line (not higher).
  • Page 13: High And Low Flame

    HIGH & LOW FLAME If priming is not done correctly (unsteady flame, “spitting” burner), you will have to wait for a moment. Usually the burner will soon reach the required tempe- rature for operation (in about 10-20 seconds). If that doesn’t work, repeat priming once more.
  • Page 14 TURN OFF THE STOVE 1. Turning off: gas As always with gas cartridges: everything is easy! Just turn off the valve (= clockwise), and that’s it. The rest of the gas in the fuel line will evaporate without residue. 2. Turning off: liquid fuel •...
  • Page 15: Hints

    HINTS Removing, unpacking and storing the stove Gas cartridge: Just unscrew the connection swivel from the valve of the cartridge . The cartridge has a built-in, one-way valve which shuts auto- matically. Liquid fuel bottle: To release the pressure in the bottle, just let the valve stay open after burning the remaining fuel in the hose, you will hear a hissing sound coming from the burner .
  • Page 16: Save Fuel

    SAVE FUEL Save fuel • Always put a lid on the pot. • Cook in a wind protected spot. • Use a heat reflector and an external windshield – especially if it is windy! • Fold the windshield so that it becomes smaller if you use a smaller pot.
  • Page 17 • Pee on it, (well, we admit that’s kind of a strange tip, but in rough times...). • Use a Primus Heat Pad. This is a 90 gr. pad that is activated with a ‘click’. Put it under the cartridge. There, it will develop a temperature of about 50°C for 15 minutes.
  • Page 18: Cooking At High Altitudes

    HIGH ALTITUDE • If the burner (stove) is not hot enough, the fuel will not burn with the small, blue flame that it should do, but with a yellow flame – like a fire and also with the occasional high flames you have in a fire. Reason: the fuel has not yet vaporised, but comes to the burner in liquid phase.

    2. Now you see the leather sealing at the lower end of the pole. Rub the leather until it gets soft, and rub the grease into it. If the sealing leather gasket is completely worn out, replace it. Off you go to your Primus dealer! 3. Re-install the pump.
  • Page 20 MAINTENANCE & CLEANING ...and what about cleaning...? The way the pump is constructed makes it possible to let the stove burn until the fuel line is empty (see page 23). This will save you a lot of cleaning and black fingers. However, it might be necessary to clean it occa- sionally, especially if you often use liquid fuel.
  • Page 21 MAINTENANCE & CLEANING 3. Then push the cleaning wire into the fuel line and move it back and forth a few times. 4. There may remain small pieces of dirt in the fuel line which you must flush out: screw the fuel line onto the generator again but without the clea- ning wire...
  • Page 22: Problems And Solutions

    The two Primus stoves Himalaya MutliFuel and VariFuel are constructed in such a way that you can make them work and run again with only a few tools, even in the wilderness.
  • Page 23 ( see main- tenance and cleaning, page 35). If you can’t solve your problems and your Primus stove refuses to perform, contact your dealer. If there is no Primus dealer at hand, call the Primus repre- sentative.

    (if the fuel bottle has been lost or broken). If you have no other choice, you may make an exception and try to screw the Primus pump into fuel bott- les from other manufacturers. It will work with most other bottles because the Primus pump is made of aluminium.
