Ever since the establishment of Primus in 1892, our Swedish engineers have been internationally recognised for designing camping stoves for explorers and adventurers. It is our genuine passion for adventure and technical solutions that has been the reason for the success of Primus innovations for more than 125 years. It is a passion and a calling that we are still on fire about.
No matter what level of adventure you want to embark on, we want to equip you with a functional and reliable camping stove that will be your valued companion for life. That is why we test every stove, individually, by hand before it leaves our high-tech factory in Europe. In this way, we can maintain the high level of quality and functionality that we demand from our products. So, read this manual carefully and make sure your cooking is as safe, fun and tasty as it should to be. Having said that, we at Primus are providing you with a tool: what you cook and where you cook - that's up to you! Enjoy your food - enjoy life in the outdoors!
A FEW WORDS ABOUT SAFETY.
Because you're dealing with highly flammable substances, we'd like to bring a few important points to your attention before you begin.
Important: Read these instructions for use carefully so as to familiarize yourself with the appliance before connecting it to its gas container. Keep these instructions for future reference.
▶ Use only in a well ventilated area.
Check the seals and connections every time you use the stove. (see the section, "Before ignition"). Do not use the appliance if it has damaged or worn seals.
Change the gas container outside and away from people. Checking the gas flows through the burners must be done outdoors and away from any naked flame.
Ensure that the stove is not used in the proximity of any combustible material, gas or fluids.
When being used, the distance from any roof must be at least 1250 mm and 500 mm from any wall.
Never leave a lit stove unattended and always ensure that inflammable material is kept away from the stove when it is in use.
Do not modify the appliance. Carefully follow the instructions for fitting spare parts that may be ordered in, if you are going to replace them yourself.
When the stove is going to be stored away, ensure that all its components are clean and dry. The gas cartridge should never be attached to the stove when in storage. Store the gas cartridge in a dry and safe place, and out of direct sunlight or temperatures in excess of 50^ C.

CHECKING THE STOVE. IMPORTANT: If
there is a leak on your appliance (smell of gas), take it outside immediately into a well ventilated flame free location where the leak may be detected and stopped. If you wish to check for leaks on your appliance, do it outside. Do not try to detect leaks using a flame, use soapy water. Contact Primus or your local dealership for replacement parts. You will find contact information on the back page of this instruction booklet.
- Smell or listen for gas leaks from the gas cartridge 6. If you are not certain, you can check by putting some soapy water on the connection to the gas cartridge. If you see any bubbles, there is a gas leak - DO NOT LIGHT the stove!

- The gas control knobs ② on the stove must be closed (turn clockwise to close) before connecting the gas cartridge.
- Check the seals before connecting a new gas container to the appliance. Do not use the appliance if it has damaged or worn seals.
- The threads on both the gas cartridge and the valve must be intact. If they are damaged in any way or awry, replace the gas cartridge - DO NOT USE the stove.
PREPARE THE STOVE. IMPORTANT: Take
care to ensure that the stove is standing with its legs fully folded out on a stable, flat surface with no combustible material nearby. Check its stability! If you tip the stove while there are pots on it, you risk being scalded by hot liquids.
- Loosen the cutting board from the shoulder strap and remove it from the stove.
- Fold out the gas supply knobs . 2
- Stand the stove on its side and attach the gas cartridge by screwing it in with a definite continuous motion as far as it will go. Do this manually.
- Fold out the stove and place it on a flat surface.
- Check that there are no gas leaks from the connection between the valve and the gas cartridge. Use soapy water as discussed in the section "Before ignition" if you are unsure.
LIGHTING THE STOVE. IMPORTANT:
UNDER NO CIRCUMSTANCES MOVE the stove when it is lit, either with or without pots. If, due to the wind, the flames are forced down under the burner, turn the stove off and move it to a more sheltered location.
- Rotate the gas supply knob 2 for the burner 5 you want to light, about one turn anti-clockwise, and use an appropriate ignition device to light the gas.
- Once the gas has been lit, you can adjust the flame and the supply of heat with the supply knob. The gas should burn directly upwards with a steady flame.
- Put the pot or frying pan on the stove after the gas has been lit.
- If you need to use two burners, light the second one the same way that you lit the first.

TURN OFF THE STOVE. IMPORTANT: Do not pack up the stove before the burners and the pan supports have cooled down. Check that burners are extinguished before disconnecting the gas container.
- Turn the stove off by twisting the gas supply knobs clockwise to the stop position. The valve is closed and the gas flow is stopped when the flame goes out. Do not use excessive force in turning off the supply; you may risk having problems when you try to turn on the supply next time.
- When you have completely finished with the stove, and both burners have been turned off, unscrew the gas cartridge 6 from the stove .1
- Fold up the stove and place the cutting board on the pan support. Secure the cutting board to the shoulder strap.
MAINTENANCE OF THE STOVE.
IMPORTANT: Regular cleaning and overhaul will extend the life of your stove. Do not try to repair screw threads or valves on the gas cartridges or the stove yourself. If the stove needs to be repaired, please contact Primus. You will find contact information on the back page of this instruction booklet.
-
The stove should be wiped clean with a cloth and a mild cleanser, e.g. dish-washing liquid.
-
Examine the wooden parts. If they have been wet and have now dried, give them a lightly application of oil.
- Reassemble the stove completely when fully dry. The deepest part of the drip tray should be closest to the lid.
IMPORTANT INFORMATION CONCERNING GAS CARTRIDGES.
This appliance shall only be used with Primus 100 g, 230 g or 450 g single-use cartridges (marked 2202xx, 2206xx and 2207xx respectively). Attempting to attach gas cartridges that are not designed for the stove can be dangerous.
