5. Operating Instructions
To ignite and operate your fire pit:
- Open Gas Supply: Slowly open the valve on your propane tank.
- Ignite: Locate the control knob on the side of the fire pit. Push the knob in and turn it counter-clockwise to the 'LOW' position. While holding the knob in, press the igniter button repeatedly until the burner ignites.
- Adjust Flame: Once ignited, continue to hold the knob in for 10-15 seconds to allow the thermocouple to heat up. Release the knob. You can then adjust the flame height by turning the control knob between 'LOW' and 'HIGH'.
- Turn Off: To turn off the fire pit, turn the control knob clockwise to the 'OFF' position. Then, close the valve on the propane tank.

7. Troubleshooting
If you encounter issues with your fire pit, refer to the following common solutions:
- Burner Does Not Ignite:
- Check if the propane tank valve is fully open.
- Ensure the igniter electrode is clean and properly positioned near the burner.
- Verify that the control knob is pushed in and turned to the 'LOW' position before pressing the igniter.
- Check for gas flow by listening for a hiss when the knob is turned. If no hiss, check tank level or hose connection.
- Low Flame:
- Ensure the propane tank is not low on fuel.
- Check for kinks or obstructions in the gas hose.
- Confirm the control knob is turned to the 'HIGH' position.
- The tank's overfill protection device (OPD) may have been activated. Turn off the fire pit and tank, wait 5 minutes, then slowly reopen the tank valve and re-ignite.
- Flame Goes Out:
- Ensure the thermocouple is properly heated. Hold the control knob in for 10-15 seconds after ignition.
- Check for strong winds that might be extinguishing the flame. Consider a wind guard (sold separately).
