IMPORTANT: For the automatic safety shutoff mechanism to function as intended, the wick must be 

free of gummy tar deposits. This can be accomplished by regularly "dry burning" the wick as described 

on page 7 under "Wick Maintenance" and "Carbon Removal / Dry Burning."

CAUTION

The operation of the automatic safety shutoff mechanism should be checked periodically, i.e., once a 

week during the heating season.  This can be done by using the wick control knob to raise the wick 

to the fully upright position. DO NOT LIGHT THE WICK FOR THIS TEST. Grasp the upper corners of 

the protective grille and give the heater a firm shake. If the safety shutoff is working correctly, you will 

hear a loud snap as the latch disengages from the ratchet and the torsion spring quickly drops the wick. 

Now attempt to rotate the wick control knob counterclockwise. A correctly functioning automatic tipover 

device will lower the wick completely.  If you are able to lower the wick further, this indicates it is time 

to "dry burn" for carbon and tar removal again. 

NOTE: Every time the wick is removed and replaced, the safety shutoff must be tested to insure it 

is operating properly. 

XI. LONG TERM STORAGE 

(1) Agitate and rinse inner part of the tank with a little of the remaining kerosene, then pour out entirely. 

Water never mixes with kerosene, and it causes rust inside the tank. Remove all kerosene. 

(2) With the kerosene out of the fuel tank, ignite and keep the wick burning. Keep the wick fully turned 

up until it burns out (about an hour). 

(3) Detach the body, burner and batteries. Remove the wick adjuster from the fuel reservoir, dry the 

inside of the fuel tank thoroughly. Remove the carbon accumulated on the wick adjuster and/or the 

soot adhering to the burner with a brush or screwdriver. 

(4) After cleaning, reassemble the heater. Remember to reassemble the wick adjuster so as to keep the 

gap between the wick adjuster and wick guide cylinder equal all the way around. Refer to page 8 

"Wick Replacement." 

(5) The batteries should be taken out from the battery case because they may leak and corrode the 

kerosene heater.(see fig.22) 

(6) Store the kerosene heater with the tipover extinguishing device deactivated and the wick lowered 

down. 

(7) Put the kerosene heater in the original box with original packing (reassemble the guard) and keep it 

in a well-ventilated place. Also keep the Owner's Manual with heater.(see fig.23) 

Store the kerosene heater carefully using the following procedure so it will operate safely next season.
