FUEL INFORMATION The XGKTM EX stove burns a variety of fuels by using twodifferent Jets.1. The GK Jet is used for white gas, kerosene, unleaded auto gas, and aviation gas. This Jet is preinstalled in your stove.2. The X jet is for jet fuel, and diesel. This jet is included in the parts kit with your stove.Use MSR® SuperFuelTM (White Gas) for optimal performance. It is the highest quality fuel available for your stove. Do not use leaded fuels. Fuels other than MSR SuperFuel white gas can lead to rapid stove clogging and require more frequent Jet and Fuel Line cleanings. Also, the use of Unleaded Auto Gas may shorten stove lifespan.Visit www.msrgear.com for more information on international fuel names and safe stove transportation.
PREPARE FUEL BOTTLE The XGK EX stove is sold with two interchangable Jets so it can burn a variety of fuels. To ensure the correct Jet is installed for the type of fuel to be used, see Fuel Information. 1. Fill Fuel Bottle to fill line only. Air space is necessary for fuel expansion. 2. Insert Pump into Fuel Bottle and firmly tighten. 3. Close the Pump Control Valve, then stroke Plunger (20-30 strokes). Less fuel requires more strokes or pressure. Pump until firm resistance is felt.—Stroke

DANGER Use MSR® fuel bottles only. Non-MSR® fuel bottles may leak fuel creating an unsafe situation leading to fire, burns, severe injury or death. Keep children far away from stove and fuel–Cascade Designs, Inc. recommends no less than 10 feet (3+ meters). Use extreme caution when using stove in temperatures below freezing. In freezing temperatures O-rings can stiffen and leak fuel. Always check for fuel leaks before and after pressurizing bottle, priming, and during and after lighting stove. Use of a leaking stove can cause fire, burns, severe injury or death.1. SET UP STOVE 1. Rotate the stove legs and pot supports. 2. Place stove on the centerof heat reflector.DANGER Keep combustibles at least 4 feet (1.2 meters) away from the top and sides of a burning stove, or a stove that you are in the process of lighting. Keep flammable liquids and vapors at least 25 feet (7.6 meters) away from the top and sides of a burning stove, or a stove that you are in the process of lighting. This stove can ignite combustible materials, flammable liquids and vapors creating a situation where fire, burns, severe injury or death can result. This stove is designed for the outside (i.e., not within enclosed spaces of any kind; e.g., tents) boiling of water or cooking of food only–never use it for any other purpose. Use of stove within any enclosure, or for a purpose other than boiling water or cooking food can cause fire, burns, severe injury or death. Always use stove on a solid, stable, even surface to avoid tipping and spills. Tipping of stove can result in an unsafe situation where fire, burns or severe injury or death can occur.2. CONNECT STOVE AND PUMP 1. Insert the fuel line into pump. With fuel bottleon its side, control valve points up. 2. Secure the catch arm on fuel pump groove. Keep fuel line straight for safety.DANGER Before every use, look for fuel on the fuel bottle, pump, fuel line, burner, and on the area beneath and around stove. Do not light stove if you see or smell fuel. See Troubleshooting. Use of stove where fuel has leaked and/or is leaking can cause fuel to ignite causing fire, burns, severe injury or death. Never disconnect the fuel line, pump, or fuel bottle when stove is burning, hot, or near any open flame. Never disconnect fuel line, pump, or fuel bottle when control value is in an open (i.e., fuel flowing) position. Disconnecting fuel line, pump, or fuel bottle when stove is burning, hot, or near any open flame, or disconnecting fuel line, pump, or fuel bottle when control value is in an open (i.e., fuel flowing) position can lead to spilled fuel that can ignite and cause fire, burns, severe injury or death.3. PREHEAT STOVE 1. Release only 1/2 tablespoon of fuel. Open control valve 1 turnand let fuel flow for 3 seconds. Close control valve. Look for fuel in burner cup and on priming pad. 2. Light fuel. A brief soccer ball size flame is normal.DANGER Never place your head or body above the stove while priming, lighting, or cooking. Because stove maintains an open flame, placement of head or body above stove is an unsafe practice that can cause fire, burns, severe injury or death. Never use excess fuel to preheat stove. Use of excess fuel for priming can lead to leaking or spilled fuel that can cause fire, burns, severe injury or death.4. TURN STOVE ON 1. Wait for preheat flame to reduce in size. 2. Open 1/2 turn andwait for steady blue flame. 3. Slowly open control valve.DANGER Never relight a heated stove. Always let an extinguished stove cool for at least 5 minutes before relighting. Relighting a heated stove can cause large flames that can cause fire, burns, severe injury or death. Never move a burning or hot stove. Always extinguish stove and cool for at least 5 minutes before moving. Moving a burning or hot stove can cause fire, burns, severe injury or death. Never leave a burning or hot stove unattended. An unattended stove can lead to fire and/or a situation where children, pets, or the unwary can be burned, injured, or killed.5. USE STOVE TO COOK 1. Set up Windscreen. Fold the ends of Windscreentogether. Leave a 1-inch (2.5 cm) gap between Windscreen and pot for optimal performance. Ensure that combustion flow and ventilation air are free of any obstruction. Use Windscreen to improve performance in all conditions. 2. Add appropriate food or liquid to cookware. 3. Place cookware onto the center of stove. 4. Maintain Fuel Bottle pressure. Add approximately 10 strokes every 10 minutes to maintain performance. Hold Fuel Bottle firmly while pumping.DANGER Keep fuel bottle away from the stove burner and other heat sources. Position connected fuel bottle so that it is as far away from the burner as possible. Use of bottle near burner or other heat sources can result in the fuel bottle exploding and causing fire, burns, severe injury or death. Never place Windscreen around fuel bottle. Never use cookware with a diameter greater than 10 inches (25 centimeters). Never place and operate two or more stoves together. Never operate stove with empty or dry cookware. Never use non-MSR® reflectors or diffusers. Use of stove in any of the proceeding manners can result in the fuel bottle exploding and causing fire, burns, severe injury or death. Never use cookware of any size that is ill-suited and/or inappropriate for use with stove or stove pot supports (e.g., cookware with a convex or concave bottom, some enameled cookware, etc.). Use of stove with ill-suited and/or inappropriate cookware can result in cookware and/or stove instability and a situation where hot cookware and/or cookware contents can spill and cause fire, burns, severe injury or death. Cascade Designs, Inc. warrants the use of appropriately sized MSR® brand cookware only–use of cookware other than MSR® brand cookware will be at user’s own risk and discretion.6. TURN STOVE OFF 1. Close Pump Control Valve on Fuel Bottle. Residual flame willcontinue to burn with a small flame for several minutes. After flames are out, wait 5 minutes for stove to cool. 2. Unlock Catch Arm and remove Fuel Line from Pump. 3. Depressurize Fuel Bottle and repack stove. Hold Fuel Bottle upright, away from your face and any sources of heat or ignition. Slowly unscrew pump to depressurize Fuel Bottle. To transport the Fuel Bottle, the Pump may be left inside a depressurized Fuel Bottle. The Pump can also be removed and replaced with the Fuel Bottle Cap.DANGER Always store fuel bottle with cap securely tightened where it cannot be accessed by children. Storage of fuel bottle with loose cap and/or where accessible by children can result in a child obtaining possession of fuel bottle and accessing bottle contents. Exposure to bottle contents topically and/or by ingestion can cause poisoning, severe injury, or death. Always store fuel bottle in a well-ventilated location away from any possible heat or ignition source such as: water heaters, stoves, pilot lights, or furnaces. Storing bottle near any heat or ignition source can result in the fuel bottle exploding and causing fire, burns, severe injury or death.
