Setup and Assembly
- Unpacking: Carefully remove all components from the packaging. Inspect for any damage. Retain packaging for future storage or transport.
- Placement: Choose a level, non-combustible surface for the fire column. Ensure it is placed in an open, well-ventilated area, away from any overhead obstructions or combustible materials. Maintain the minimum clearances specified in the safety section.
- Battery Installation: Locate the battery compartment for the electronic ignition. Install one (1) AA battery (not included) with the correct polarity.
- Fire Glass Placement: Carefully place the provided black fire glass around the burner assembly. Ensure the burner ports are not obstructed by the glass.
- Propane Tank Connection:
- This fire column is designed for use with a 1 lb (0.45 kg) propane cylinder.
- Ensure the control knob on the fire column is in the "OFF" position.
- Screw the 1 lb propane cylinder clockwise into the regulator connection until hand-tight. Do not overtighten.
- For use with a 20 lb (9.07 kg) propane tank, a separate adapter hose (not included) is required. Follow the adapter hose manufacturer's instructions for connection.
- Perform a leak test on all gas connections using a soapy water solution. Bubbles indicate a leak. If a leak is detected, turn off the gas supply immediately and tighten connections. Do not operate the unit if a leak persists.

Operating Instructions
- Before Lighting: Ensure the area around the fire column is clear of any flammable materials. Confirm the propane tank is securely connected and the gas supply valve is open.
- Lighting the Burner:
- Press and hold the electronic ignition button.
- While holding the ignition button, slowly turn the control knob counter-clockwise to the "LOW" position.
- The burner should ignite within a few seconds. If it does not ignite, release the ignition button, turn the control knob to "OFF", wait 5 minutes for gas to dissipate, and repeat the lighting procedure.
- If the burner still does not ignite after several attempts, refer to the Troubleshooting section.
- Adjusting Flame: Once lit, rotate the control knob between "LOW" and "HIGH" to adjust the flame height to your desired level.
- Shutting Down:
- Turn the control knob clockwise to the "OFF" position.
- Close the gas supply valve on the propane cylinder.
- Allow the fire column to cool completely before moving or covering.

Maintenance
Regular maintenance will ensure the longevity and safe operation of your fire column.
- Cleaning:
- Ensure the fire column is completely cool before cleaning.
- Wipe exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Clean the fire glass periodically to remove any debris.
- Gas Line Inspection: Periodically inspect the gas hose and connections for any signs of wear, cuts, or leaks. Replace if damaged.
- Propane Tank Replacement: When replacing the 1 lb propane tank, ensure the fire column is off and cool. Carefully unscrew the empty tank and replace with a new one, ensuring a tight seal. If using a 20 lb tank with an adapter, follow the adapter's instructions for disconnection and reconnection. Some users find it easier to gently tilt or invert the unit to access the tank compartment, but care must be taken to avoid spilling fire glass.
- Storage: When not in use for extended periods, disconnect the propane tank and store the fire column in a cool, dry place, preferably covered to protect it from the elements.
