STOVE MAINTENANCE

Deposits in the Jet and Fuel Line can reduce fuel flow and affect the performance of your stove. You can easily clear minor deposits in the Jet using the Shaker Needle. For more significant deposits, you might need to do a more thorough cleaning of the Jet and Fuel Line. It's a good idea to carry out the following maintenance at least once a year or whenever you do the Pump Maintenance.

CLEARING THE JET WITH THE SHAKER NEEDLE
1. Close Pump Control Valve and wait 5 minutes for stove to cool.
2. Shake stove up and down.
Shaker Needle inside Jet should rattle.
3. Preheat and run stove.
If performance does not improve, perform Cleaning the Jet and Fuel Line steps.

CLEANING THE JET AND FUEL LINE
     1. Fold Pot Supports/Legs to packed position.
     2. Unscrew Priming Cup and remove Wick.
     3. Hold folded Pot Supports/Legs together.

     
Remove Fuel Line from Mixer Tube.
4. Unscrew Jet with Jet and Cable Tool.
IMPORTANT: Do not bend Generator Tube while loosening Jet.

5. Remove Shaker Needle and use it to clear Jet Orifice from top or bottom.
NOTE: To exchange Jets, place Shaker Needle in new Jet and reassemble stove.

6. Scour Fuel Line.
Unscrew Fuel Adapter from Fuel Line.
Remove Cable from Fuel Line with Jet and Cable Tool. Stubborn cables can be
loosened with a common lubricant (WD-40™, Pump Cup Oil, etc.).
Fully reinsert Cable into Fuel Line.
Move Cable in and out with 5-inch (13-centimeter) strokes approximately
20 times.
Wipe Cable clean.

7. Flush Fuel Line.
Remove Cable.
Connect Liquid Fuel Adapter to Fuel Line and install into Pump and Fuel Bottle.
Secure Catch Arm on Fuel Pump Groove.
Pressurize Fuel Bottle with 15 strokes.
Fully open Control Valve to flush 4 spoonfuls of fuel through Fuel Line into an
appropriate container. (Jet uninstalled.)
WARNING: Keep away from ignition sources.
Close Control Valve and remove Fuel Line.
Safely dispose fuel when flushing is complete.
8. Reassemble stove.
If stove performance is still impaired, repeat Cleaning the Jet and Fuel Line steps.
