Liquid Fuel Stove Maintenance

Fill the tank 7/8ths full with white gas (Coleman fuel). Check the tank cap

seal by holding the fuel tank upside down and looking for leaks.

Pump the tank 10 to 20 times, with the control valve closed. Plug the tank

and generator into the stove so that it fits securely in the proper spot. (The

generator rod should be plugged into burner body).

Make sure that the secondary burner-regulating key (on left side of stove)

is turned off.

Turn the lighter stem on the generator/valve assembly to the Up position.

Open the control valve and light the primary (right) burner. After one

minute of burning, turn the lighter stem to the down position. Adjust the

flame with the control valve and by pumping up the tank.

The second (left) burner can now be ignited by turning on the regulating

key on the left side of the stove and lighting the burner with a match.

Note: You can effectively preheat this stove by putting Coleman fuel or Meta-paste in the

primary burner bowl under the generator stem, lighting it, and allowing it to burn down

before turning on the stove and lighting the stove.
