OPERATION IN COLD CONDITIONS
WARNING!
Freeze Hazard
Severe injury may occur to personnel handling metal parts without protective gloves when
temperatures are below freezing. Skin may freeze upon contact and tear from the flesh.
Do not allow fuel to come in contact with bare skin. Even though fuel does not freeze, it is
extremely cold and will burn exposed skin on contact. Wear protective gloves whenever
handling or working with liquid fuel.
Solid and liquid fuel operation. Do not handle metal components without protective gloves when
temperatures are below freezing (32 degrees Fahrenheit).
Solid fuel operation only. Do not overfuel the heater. This could cause overheating of stack assembly
and ignite tent fabric.
Liquid fuel operation only. When temperature is below -25 degrees Fahrenheit (-31 degrees Celsius),
use JP-5, JP-8, or DF-A fuel.
OPERATION IN HIGH ALTITUDE CONDITIONS
Solid and liquid fuel operation. Inspect heater operation more frequently.
Solid fuel operation only. Adjust sliding draft gate as required to prevent over firing.
Liquid fuel operation only. Lower than normal operating settings of flow adjustment knob may be
desirable to prevent over firing and carbon buildup.
OPERATION IN RAINY OR HUMID CONDITIONS
Solid and liquid fuel operation. If tent is set up on in extremely damp and muddy areas, set heater legs
on stones or boards to prevent it from sinking.
Take extra precautions in securing stack cap and telescoping stack assembly with ground stakes (ie: use
longer stakes).
If heater has been exposed to rain, drain it of any large water deposits before trying to light it off.
Solid fuel operation only. Store matches, kindling, coal and wood in a dry, sheltered location.
If the only supply of re-fuel available is wet or damp, position a regular amount of the wet/damp fuel next
to the operating heater to dry for refueling purposes.
Liquid fuel operation only. Prevent fuel contamination by keeping lids tightly on fuel containers.
