The overview applies to a single stove and one person, cooking an average amount of freeze-dried food including coffee and tea breaks. For two people and a single burner stove, increase comsumption by about 50 % in winter. The levels of consumption specified above should be considered as guidelines. Variations can be expected depending, amongst other things, on the wind, temperature, number of people and type of food. Protection from the wind is of the outmost importance to keeping the consumption at a low level. Winter consumption includes melting snow. Pots equipped with heat exchangers help to increase fuel efficiency and reduces fuel consumption (approx. 50%). This means less packaging weight and volume as well as lower carbon dioxide emissions.

Summer

• 1 Day: 100 g Gas = 0,1 L Liquid Fuel
• A weekend: 230 g Gas = 0,3 L Liquid Fuel
• A week: 2 x 230 g = 0,8 L Liquid Fuel

Winter

• 1 Day: 230 g Gas = 0,2 L Liquid Fuel
• A weekend: 450 g Gas = 0,6 L Liquid Fuel
• A week: 450 g + 230 g = 1,5 L Liquid Fuel

There are many different types of fuel available for camp stoves, but what is the difference? The table below helps to rank the most popular fuels available on the market by highlighting how much energy each emits. 

Heat kcal/kg = the amount of energy that 1 kilogram of fuel gives off as heat when burned. The higher the number, the better. The higher the number, the less fuel you need to carry to do the same job.  

Boiling Point Index = fuel ranking for easier comparison (1-100), with Primus Gas setting the curve. This means that if you burned methylated spirits, you would need almost twice as much to boil the same amount of water as Primus Gas. 

ENERGY VALUE: Heat kcal/kg - Boiling power index

• Primus Gas: 11900 - 100
• Propan: 12000 - 101
• Butane: 11800 - 99
• White gasoline/petrol: 10200 - 86
• Kerosene/paraffin: 10100 - 85
• Diesel: 9800 - 82
• Charcoal: 8400 - 71
• Methylated spirits: 6300 - 53
• Dry wood: 4000 - 34

As our stoves are designed for different occasions, there are slight differences in the way you access the jet to clean it properly. However, the principle remains the same.

OmniFuel and Multifuel Stoves

Gas is stored above atmospheric pressure in gas cylinders. A new, full gas cartridge has the highest pressure and decreases during use. Pressure also varies with temperature and altitude. A pressure-regulated valve adjusts to temperature and altitude, providing consistent performance, whereas non-regulated valves do not adjust and therefore have less consistent performance. 

Ultimately, stoves with pressure-regulated valves work better in cold conditions and perform better when fuel levels are low - the regulation system simply adjusts the gas flow output to maintain an optimum level. 

A regulated stove: 

• is more efficient. 
• performs better in cold conditions.  
• has a more consistent heat output.  
• is easier to adjust the temperature. 
• allows you to use more gas from your canister. 

When you turn the gas knob, a spring is tensioned and opens the valve, allowing the gas to flow out of the canister. When the gas pressure on the diaphragm is higher than the pre-set allowable pressure, the diaphragm pushes on the spring to regulate the spring, which in turn regulates the valve opening and gas flow. This ensures that the gas flow is always regulated to an optimum level.

A catalytic infrared burner operates differently to a standard burner. A standard burner mixes air with fuel and the flame burns on the top/outside of the burner to heat the pot. In a catalytic infrared burner, the fuel and air mix inside the burner and burn with the help of a catalyst material to improve the combustion process. The catalyst material is usually a specific metal alloy that reduces the activation energy required for the combustion reaction to occur. The result is a more complete combustion of the fuel. In our stoves, we use a porous metal structure to carry the catalyst material and house the combustion. The porous metal pad begins to glow and radiate infrared heat, providing additional heat energy to the reaction and heating the pot together with the hot air produced by the combustion. One of the major advantages of using a catalytic infrared burner is its resistance to wind, making it an excellent choice for melting snow, boiling water and cooking food in all outdoor conditions. 

In addition to its high efficiency in windy conditions, other benefits of using a catalytic infrared burner include increased energy efficiency. The more complete combustion facilitated by the catalyst helps to reduce harmful emissions such as carbon monoxide. In addition, the use of infrared radiation allows precise temperature control, making catalytic infrared burners ideal for situations where consistent heating is required. 

Our multifuel stoves do exactly what their name implies - they run on different types of fuel. Whether you have access to propane, white gas, kerosene/paraffin or jet fuel, these stoves will perform in all weather conditions. 

From fuel catridge to combustion

With the ErgoPump™, you pump up the pressure in the cartridge so that fuel reaches the burner at all angles, no matter how much fuel is left. 

The burner heats up during preheating and use, vaporising the fuel. Ultimately, whatever fuel you use, it's the vaporised fuel that burns. 

The burner nozzles are interchangeable to optimise the heat output for each type of fuel. Each individual nozzle is clearly marked so that you can easily match it to the fuel you intend to use. 

Fuel with a higher flash point, such as diesel, requires more oxygen to burn with optimum efficiency. It requires a smaller nozzle as the air supply is always the same regardless of the type of fuel you are using. Fuel with a higher flash point requires more preheating, which is optimised by a lower fuel flow. 

The multifuel stoves produce a powerful flame, so the stoves work in the most extreme weather conditions. This, combined with their light weight, makes our multifuel stoves an excellent choice for the most demanding adventurer. The pump is designed to suck in air instead of fuel when the cartridge is upside down. This relieves pressure from the entire system and prevents you from having to deal with excess fuel. 

Thank you for your loyalty to the expedition stove. It may look a little old, but it is far from obsolete. At Primus we believe in making products that last. 

So we have made sure that our new models and spare parts have the same dimensions.This means that the Hose Replacement-EXPEDITION will still fit your stove (P731930). 

Only the models with cleaning wire (e.g. Himalaya Multifuel) require a small modification.  

This wire must be shortened by a few millimetres to allow the new hose to be connected. There is no loss of performance. 

A non-stick coating is handy when frying or sautéing and and makes cleaning easier. We use two types on our aluminium pots and pans: 

PTFE (WHITFORD) NONSTICK COATING: 

We use a PTFE coating from Whitford for some of our non-stick coatings. PFTE offers low friction and can withstand high temperatures, making it a great option when you need something that is non-stick. However, it is a little sensitive to scratching and too high a cooking temperature will ruin the coating. The PTFE used in our products is PFOA free. PTFE is the best choice for most standard food preparation and temperature sensitive ingredients such as eggs. 

Primus products with PTFE 

• Essential Stove System (pan only) 
• Essential Pot Sets (pan only) 
• LiTech Pot Sets 
• LiTech Coffee Kettle 
• LiTech Trek Kettle 
• Campfire Griddle Plate 

NON-STICK CERAMIC COATING

Ceramic coating is a great choice for outdoor cooking as it is tough and can handle the high heat of a gas flame or open fire safely. Ceramic coating is the best all around choice for cooking and heavy frying. 

Primus products with ceramic coating 

• Ulti Pots 
• Essential Trek Pots (pan only) 
• Primtech Stove System (pot with heat exchanger only) 
• Primetech Pot Sets 
• Trek Pots 
• LiTech Frying Pans 
• Kuchoma (grill grate only) 

NO COATING

Anodised, uncoated aluminium is used in our cookware where the primary use is to heat or boil water, without frying or sautéing. Note that these pots should not be used with very salty or acidic foods as these will corrode the material. This is the best choice for boiling water.

As a rule of thumb, 6 hours, but this is variable and depends on the external circumstances. 

For a vacuum flask to work properly, it must have a high level of insulation between the two flasks, the outer casing and the inner flask. To minimise heat transfer, the space between the cylinders is a vacuum - a space without material. As a result, heat transfer between the inner liner and the outer shell is minimised and heat is retained inside the vacuum flask. This principle keeps your food and drink cool or hot, depending on what you put in the container. 

The inside and outside of the two layers are polished to absorb as little heat as possible and reflect it instead.

It may be that your vacuum flask has lost its vacuum and therefore its insulating capacity. There is a simple way to check if this is the case. Fill the insulation bottle with hot water and feel the outside of the flask with your hands for a while. If the outside gets hot, it has lost its vacuum. This can happen if the bottle is knocked, dropped or otherwise punctured, but should not happen in normal use.

When you’re travelling around the world it is important to use the correct adapter for your gas canister. We want you to be able to use your stove wherever you are. Purchase of our CampFire stove includes a Lindal Valve that fits our Power Gas, Summer Gas and Winter Gas canisters. For other gas canisters, we have a range of connection adapters that fit most of the variants that are available in the market.

Please have a look at our adapter guide!

ATLE is fitted to a refillable propane cylinder (with M14 x 1.5 connections); an additional hose and regulator are included in the scope of delivery. Also included is an adapter that enables use with the LPG cylinders with left-hand thread commonly used in Germany. An adapter to an M16 thread is also included (Campingaz).
Not suitable for use with Primus Power Gas, Winter Gas or Summer Gas.

The lighter may have trouble igniting if the gas flow is either too high or too low. This may occur due to changes in air pressure or elevation. But the gas flow can be adjusted to solve this issue. You do this by rotating the cylinder around the refill valve in the bottom of the lighter. There is also a Philips screw in the bottom, but this screw only holds the parts together and has nothing to do with the gas flow. We also have a video showing this process. Try this, and I hope you’ll get it to work again.

In this case, please use our contact form. Our support team will try to help you with your search. Photos are particularly helpful if you do not know the item number or name.

We currently offer two Primus options for using your Campfire camping stoves with a longer hose: 

The simplest option would be to replace the 50 cm hose supplied with the 100 cm extension hose P741170. This maintains the variability of the connection types. More on this in our guide. 

Video - How to install the extension hose

The second option would be the 16.4 OZ TO POL adapter (P741120) with hose. However, this would only be an option if the gas cylinder to be used has a POL connection. This 150 cm long adapter would then be screwed between the POL gas cylinder and the regulator. 

However, it is important to ensure that the 16.4 OZ adapter (P741320) is attached to the pressure reducer beforehand. The easiest way to do this is explained very well in this video. This configuration results in a total length of 2 metres. 

It is quite possible that there are other options from third-party suppliers for using a longer gas hose. However, we would like to point out that the supplied regulator must always be used and that our camping cookers are intended for outdoor use only.

Primus no longer stocks parts for the older burners. There are some forums on the internet for enthusiasts of old stoves. You could visit www.classiccampstoves.com and see if you can find some information about the stove there.
Try to keep as many original parts as possible. Just check that the O-rings and seals still look fine.
There are other suppliers on the market who can supply suitable seals. Your local gas specialist will also be able to help.

Sometimes it may be sufficient to readjust the wire, making sure that the distance between the tip of the wire and the torch head is 4 mm.
If there is no spark at all or the wire is missing completely, a repair is necessary.
Fortunately, this can be done quickly and easily at home. Here is the link to the video explaining the repair.
If a new piezo (P737650) is not available, in some cases a wire from a paper clip or even a stapler needle can be used to make the spark jump.
