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).
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.
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.
WARNING
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 centi-
meters). 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, particularly 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.
WARNING
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.
WARNING
WARNING
Do not use this stove: (1) before reading and fully understanding this Instruction Manual; (2) if you are not
prepared or comfortable attending to a burning and/or hot stove at all times; (3) if you observe leaking fuel;
or (4) if you observe any condition with the stove system or in the surrounding environment that would make
operation of an open flamed device dangerous. Failure to follow these directions can cause an unsafe situation
leading fire, burns, severe injury or death.
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 enclosure 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.
WARNING
WARNING
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.
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.
WARNING
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.
