Setup Instructions
Your Flame King Propane Torch Kit arrives fully assembled. Follow these steps to connect it to a propane cylinder:
- Ensure all valves are closed: Before connecting, verify that the torch's flame control knob and the propane cylinder's valve are in the OFF position.
- Connect the hose to the propane cylinder: The 10-foot hose features a POL safety valve with a handwheel tightener. This fitting is reverse-threaded.

Tighten the handwheel by turning it counter-clockwise (lefty tighty) until secure. Do not overtighten.
- Check for leaks: After connecting, open the propane cylinder valve slowly. Apply a soapy water solution to all connections. If bubbles appear, close the cylinder valve immediately and re-tighten the connection. Repeat the leak test. Do not proceed if leaks are detected.
- Position the cylinder: Place the propane cylinder on a stable, level surface, ensuring it remains upright during operation. The 10-foot hose allows for flexible positioning.

Operating Instructions
Follow these steps for safe ignition and operation of your propane torch:
- Prepare the area: Ensure the operating area is clear of all flammable materials and that you are wearing appropriate PPE.
- Open cylinder valve: Slowly open the propane cylinder valve. A quarter to half turn is typically sufficient for most tasks.
- Adjust flame control knob: Turn the torch's flame control knob about 1/8 of a turn to allow a small amount of propane to flow.
- Position the torch: Point the torch nozzle away from yourself, other people, and any flammable objects.
- Ignite the torch: Press the push-button piezo igniter to light the flame. If it does not ignite immediately, adjust the flame control knob slightly and try again.

Image: Step-by-step diagram illustrating the ignition process: 1. Verify all valves are closed. 2. Open cylinder valve slowly. 3. Open the torch knob about 1/8 of a turn. 4. Ensure the boost control lever is not pushed down. 5. Ignite with the push-button igniter. Important: Point the torch away from people and flammable materials before igniting.
- Adjust flame intensity: Once ignited, use the flame control knob to adjust the flame to the desired intensity. For maximum heat (340,000 BTU), fully open the knob. The idle boost control lever can be used for momentary bursts of higher flame.
- Typical Applications:
- Weed Burning: Briefly pass the flame over weeds. The goal is to heat the plant cells, not to incinerate the plant. The weeds will wilt and die within a few days.

- Weed Burning: Briefly pass the flame over weeds. The goal is to heat the plant cells, not to incinerate the plant. The weeds will wilt and die within a few days.
- To shut down: First, close the valve on the propane cylinder completely. Allow the flame to extinguish from the remaining gas in the hose. Then, close the flame control knob on the torch.
- Cool down: Allow the torch to cool completely before handling or storing.
Maintenance
Proper maintenance ensures the longevity and safe operation of your Flame King Propane Torch Kit:
- Cleaning: Keep the torch nozzle and air intake vents free from debris. Use a soft brush or cloth to clean the exterior. Do not use abrasive cleaners or solvents.
- Hose Inspection: Regularly inspect the propane hose for cuts, abrasions, cracks, or any signs of wear or damage. Replace the hose immediately if any damage is found.
- Connection Inspection: Periodically check all connections for tightness. Re-perform a leak test with soapy water if you suspect a leak or after prolonged storage.
- Storage: Disconnect the torch from the propane cylinder after each use. Store the torch in a clean, dry place, away from extreme temperatures and direct sunlight. Ensure the propane cylinder is stored separately in a well-ventilated area, away from ignition sources.
