The first time the heater is lit, it should be done outdoors to allow residues of 

oils and waxes used in manufacturing the heater and the wick to burn off. This 

will eliminate any odors from this initial light up from collecting inside the home. 

TOO HIGH

 Produces smoke 

and soot 

TOO LOW

 Produces odor or 

carbon monoxide 

CORRECT 

Most efficient 

combustion 

V. WICK ADJUSTMENT

Observe the heater flame during this initial light up. During the first 5 minutes, flames will gradually build 

up and appear at the top of the burner. As the burn chamber warms, the kerosene fuel will vaporize from 

the wick more easily. After 5-7 minutes, you will be able to use the wick adjuster knob to correctly 

position the flames at the top of the burner so that no more than

 of flames appear, 

distributed evenly around the circumference of the flame spreader disk located in the center top of the 

burner. Four notches will appear in the flame where the crossbars in the burner deflect the air flow. 

 

Because of changes in heater temperature and in room temperature, subsequent adjustments 

will be required after 60 minutes and periodically thereafter. 

IV. AUTOMATIC IGNITION SYSTEM 

IGNITION BY MATCH 

The heater has been designed to be lit by using the automatic ignition system. 

This system consists of 2 "C" cell batteries, connecting wires, a manual arm 

which holds the igniter itself and which, when pushed, raises the burner and 

brings the igniter in contact with the wick after the wick has been raised to its 

maximum height. 

The ignition sequence is as follows: Open the door below the mica window. 

Push in the auto start knob, The burner will be lifted up and the igniter coil will  

appear and begin to glow. Hold the auto start knob in and turn the wick adjuster 

knob clockwise to raise the wick. As the wick approaches the glowing igniter 

ignition will occur. As soon as flames are observed through the open door, 

release the igniter knob which will lower the burn chamber back down over the 

wick. It is important to rotate the burner knob left and right, back and forth, a 

few times to insure that the burner is properly located on the wick adjuster. 

Should you experience difficulty with the igniter mechanism or dead batteries, 

the heater can be lit using a match. This is done by raising the wick, lifting the 

burner using the burner knob, and applying a lighted match to the exposed top 

edge of the wick.(see fig.12) 

CAUTION: Be sure to remove the match or any broken portions of it from the 

burner area. A match head left in place can cause  misalignment of the burner 

which may result in incomplete burning, odor, soot, or fire.
