allow flame to self-extinguish and 
the stove to cool. If necessary, 
invert stove to remove excess 
liquid fuel from the burner. Follow

assembly. Please contact 
Consumer Service (see page 9).

Remove burner to inspect and 
clean the burner and air tube.

Squirt a few drops of oil in the

correct the problem, replace the

pump assembly.

Adjust the flame to a slightly 
higher level with the red fuel 
lever.
