WindBurner pots must be used only with WindBurner stoves. This is because the pot and stove are specifically engineered to create an integrated system.
There are currently two WindBurner stove designs. The original threads directly onto the top of the canister. It is available only in the smallest WindBurner system, the Personal 1.0 L System.
In 2017, we introduced the remote-canister design, in which the stove is remotely connected to the canister by a fuel line. This new design supports larger pots and is available in the WindBurner Duo System,Group System and Combo System.
Every WindBurner pot is compatible with the new remote-canister stove. It provides the necessary stability needed for the larger pots. Therefore, the remote-canister stove is compatible with:
If you own the 1.0 L Personal system or a first-gen 1.8 L system and your stove mounts on top of the canister, you may use these pots:
Do not use the larger 2.5 L Group Sauce Pot or 4.5 L Stock Pot on this top-mounted stove; the larger pots are less stable on this stove.
It depends on your cooking preferences.
The new remote-canister stove burner is a more versatile stove design because it provides the ability to cook with the new larger WindBurner pots. If you plan to cook for groups or make more elaborate meals in the backcountry, the new remote-canister stove is an excellent choice. It comes in the new WindBurner Duo System, the Group System and the Combo System.
If you simply want to boil water fast, and your party size is typically only 1-3 people, the 1.0 L Personal System or the first-generation 1.8 L System (which feature the stove that mounts directly on the canister) remain great options.
No, the WindBurner is not designed to be used this way. To achieve similar performance to an inverted canister in cold weather and with low fuel, the WindBurner uses a built-in pressure regulator. This regulator design allows the stove to deliver a faster and more consistent cooking experience than using the canister inverted, down to 32◦ F/0◦ C canister temp.
Do not invert the canister on your WindBurner stove. Doing so can lead to extremely dangerous flare-ups or liquid fuel build up. The fuel line connection was intentionally designed without a swivel connection to prevent such use. If you wish to use the WindBurner in temperatures below freezing, place the canister in a bowl of water. As long as the canister stays above freezing, it will operate at full output, providing fast boil times and excellent fuel efficiency.
Each airline has different rules regarding the transportation of camping stoves. Please ask your airline about their regulations.
Please note: Carrying flammable fuel on passenger aircraft in carry-on or checked luggage is forbidden. Before transporting fuel bottles on passenger aircraft, safely empty all fuel, wash inside with soapy water, rinse thoroughly, air dry, and stow bottle uncapped.
Check for the latest regulations on the TSA website.
Camping fuel (white gas) is sold in a variety of places worldwide. If you can't find fuel in an outdoor store, try a gas station or hardware store. For translations and general availability of fuels around the world see the chart at the bottom of this blog post.
Liquid Fuel Stoves — If you have a multi-fuel stove, like the XGK™, DragonFly™ or WhisperLite™ Internationale stoves, try kerosene. Just remember to use the "k" jet included with your stove (Marked K, GK, or DK depending on the stove).
Canister Fuel Stoves — PocketRocket™, WindPro™, and Reactor® stoves will only accept threaded, self-sealing canisters. If you have a SuperFly™ stove, it will work on both threaded and non-threaded self-sealing canisters, like Campingaz branded canisters.
Only clean the inside of the Cool Fuel valve if you have less than 1.5 total revolutions of the Flame Adjuster when fully assembled.
- Remove Flame Adjuster, Jet and Shaker Jet needle. For best results allow fuel line to completely dry out on the inside.
- Assemble the wire handle from the Flame Adjuster onto the DragonFly cleaning tool.
- Insert DragonFly cleaning tool into flame adjuster tube and rotate clockwise while applying firm, but not excessive, force. After 20 turns remove the DragonFly cleaning tool. Shake out debris by tapping fuel line on clean hard surface and allowing deposits to fall out of fuel line through Flame Adjuster port. Reassemble Flame Adjuster and count the number of full revolutions, If less than 1.5 repeat cleaning. After cleaning is done install Flame Adjuster and flush out the fuel line.
Flushing is required any time valve cleaning has been performed.
- Connect stove to Fuel Bottle with DragonFly Pump as if assembling for operation. (Do not include windscreen or Heat Reflector).
- Remove Flame Spreader, Jet and Shaker Jet Needle.
- Turn On/ Off Valve and Flame Adjuster ON and allow fuel to run through fuel line for 30 seconds. CAUTION: Always flush away from any ignition source. Spilled fuel is a fire hazard! Light stove away from cleaning area and only after residual fuel on stove has evaporated.
- Reinstall Shaker Jet Needle, Jet and Flame Spreader.
- Light stove. While stove is lit, adjust output several times through full range of flame. This may loosen remaining deposits.
- If clogging persists, repeat flushing process. Two or three flushing cycles are often required to completely clean out deposits.
There are several reasons your stove may have a weak flame. The most common one is that the jet and fuel line are clogged from use or from old degraded fuel.
First, try cleaning your jet. Shaker Jet stove owners simply shake your stove vigorously up and down. Non-Shaker Jet owners use the jet cleaning wire that was provided with your stove to poke out any debris that may be blocking the passage of fuel. If that does not resolve the problem, you will need to clean the fuel line.
It may also be that the fuel you are using is old. Over time, white gas degrades. The type and quality of fuel, and its exposure to air and heat will affect how fast this degradation happens. Old fuel will clog fuel lines and should be avoided.
See Cleaning the Fuel line for the WhisperLite, WhisperLite Internationale, SimmerLite & XGK EX stoves.
In general, cables become stuck due to a lack of Fuel Line cleaning and maintenance. Diminished stove performance also results from lack of maintenance. Therefore, it is important to perform routine maintenance on your stove.
Stuck cables can be removed by performing the following procedure: First, begin by familiarizing yourself with different parts of the Fuel Line, which are described in your stove instructions. Following the stove instructions, remove the Fuel Line from the Burner Assembly. Note: The DragonFly stove does not have a cable. For XGK model stoves, leave the Fuel Line and Enclosure intact while performing the following procedure. Remove the Jet by using the Jet and Cable Tool; turn Jet counterclockwise to loosen and remove. Using a common lubricant spray, direct the “straw” inside the Elbow and spray a small amount, such that the lubricant is directed inside the Fuel Line. Note: Orienting the Fuel Line vertically will facilitate better flow of lubricant into the Fuel Line. Let the Fuel Line soak for a short time; after which, refer to your stove instructions for Cleaning the Jet and Fuel Line. Pliers may have to be used to remove a cable that cannot be pulled out with the Jet and Cable Tool, regardless of using a lubricant. If pliers are used, grip the weld at the tip of the cable only. Do not grip the cable itself as this might result in fraying. A frayed cable can damage the Fuel Tube O-ring when connecting the stove with the pump; damaged O-rings can result in a dangerous fuel leaks, fire and personal injury.
The following tip applies to both models of the WhisperLite stove, the SimmerLite stove, and the WindPro stove.
Note: Stuck Jets on the DragonFly and XGK stoves can be removed with a large screwdriver or a leverage-providing implement used in combination with the Jet and Cable Tool. See Stove Instruction Manual.
Stuck Jets can be removed by performing the following procedure: First, begin by familiarizing yourself with the Mixer Tube and different parts of the Fuel Line, these are described in your stove instructions. Following the stove instructions, remove the Fuel Line from the Burner Assembly. Once the Fuel Line is removed and free from the Legs, turn the Burner Assembly “upside-down,” placing it on a bench is preferable, with the slotted end of the Mixer Tube facing up. Then, orient the Fuel Line so that the Jet is also facing up. Re-insert the Elbow into the Mixer Tube, but the “wrong way,” with the Jet exposed rather than hidden, in other words the Jet should be “sticking out” so that it can be accessed with the Jet and Cable Tool. While supporting the Fuel Line and Burner Assembly, use the Jet and Cable Tool to unscrew the Jet, turning it in a counterclockwise fashion. For Jets that are severely stuck, a screwdriver may be placed through the “air hole” in the side of the Mixer Tube so that additional leverage is provided. Note: This configuration provides support for the Fuel Line so that it does not bend while the stuck Jet is being unscrewed.
Remove the fuel canister and simply shake out as much liquid/snow, etc. as possible. Re-mount the stove on canister and light, following the stove’s included directions. You will see some steam as the remaining liquid vaporizes. The burner may not glow completely red until all water is gone, but there should be no further complications.
Always completely dry the Reactor stove before storing.
