How to Use a Thermos Catalytic Heater
Thermos catalytic heaters have not been manufactured since the 1970s. The heater runs off catalytic heater fuel, or white gas, and was designed to be used as a small space heater. When first ignited, there is a flame but after about 15 minutes, the flame will go out and the heater will continue to produce heat. Does this Spark an idea?

1
Open the fuel cap on the side of the Thermos catalytic heater. Twist the cap counterclockwise to open it.

Fill the heater with gas. Your Thermos heater should be able to use either catalytic heater gas or white gas. If you are unsure, look for a sticker on the heater that specifies which fuel to use or research the heater by looking up the model number.

Put the fuel cap back on and turn it clockwise to close it, then lift off the cap that covers the wick. The cap may have a hinge clip on the side that holds it on; if so, unhinge the hinge clip and remove the cap.

Lift up the heater, turn it upside down, and then right side up again. Repeat this process until the wick has a wet spot in the center. The wick is large and will visibly show a moist area on it when it becomes saturated with fuel.

Replace the cap on top of the wick once the flame goes out. If it has a hinge clip, latch the clip back into place.
