Exterior Natural Gas Stone Fire Pit Care Sheet
This care sheet provides detailed instructions for maintaining your newly installed exterior natural gas stone fire pit. Following these guidelines will ensure its longevity, optimal performance, and safety.
I. Initial Setup and Operation
A. First Use
Ensure the gas line valve is fully open.
Carefully follow the ignition instructions provided by the fire pit manufacturer. This typically involves turning the gas valve on the fire pit to the "on" position and pressing an igniter button, or using a long lighter.
During the first few uses, a slight odor may be present due to the burning off of manufacturing residues. This is normal and should dissipate quickly.
B. Regular Operation
Always ensure the area around the fire pit is clear of combustible materials (e.g., leaves, fabrics, flammable liquids) before ignition.
Never leave the fire pit unattended when lit.
Do not allow children or pets near the fire pit without supervision.
When finished, always turn off the gas at the fire pit control knob and, if accessible, at the main gas supply valve. Allow the fire pit to cool completely before covering.
II. Routine Cleaning and Maintenance
A. Stone and Enclosure
Cleaning Frequency: Clean the exterior stone surfaces at least once a month, or more frequently if exposed to heavy dust, pollen, or environmental debris.
Cleaning Method:
Use a soft brush or cloth to remove loose dirt and debris.
For stubborn stains, use a mild soap (e.g., dish soap) mixed with warm water.
Apply the solution with a soft brush or sponge, gently scrubbing the affected areas.
Rinse thoroughly with clean water to remove all soap residue. Avoid high-pressure washing, as this can damage the stone and mortar.
For natural stone, avoid harsh chemical cleaners, as these can etch or discolor the surface. Test any cleaning solution on an inconspicuous area first.
Algae and Moss: If algae or moss appears, a diluted bleach solution (1 part bleach to 10 parts water) can be used, followed by a thorough rinse. Ensure no bleach solution enters the burner assembly.
B. Burner and Media (Lava Rocks/Fire Glass)
Cleaning Frequency: Inspect the burner and media quarterly or before each season of heavy use. Follow the instructions provided by the manufacturer.
Burner Inspection:
Ensure the gas ports on the burner are free from obstruction. Insects, debris, or rust can block the ports, affecting flame performance. Use a soft brush or compressed air to clear any blockages.
Check for signs of rust or corrosion on the burner. While natural gas burners are designed to withstand outdoor conditions, excessive moisture can accelerate wear.
Lava Rocks/Fire Glass:
Periodically remove the lava rocks or fire glass from the burner pan.
Rinse the media with water to remove dust and debris. Allow them to dry completely before placing them back in the fire pit.
Replace any cracked or significantly discolored fire glass, as it can compromise heat distribution and appearance.
For lava rocks, remove any small, crumbling pieces to prevent them from entering the burner ports.
III. Seasonal and Long-Term Care
A. Winterization (for colder climates)
Before the first frost, or if the fire pit will not be used for an extended period during cold weather:
Turn off the main gas supply to the fire pit.
Clean the burner and media thoroughly per manufacturer's recommendations.
Ensure the fire pit is completely dry.
Cover the fire pit with a durable, waterproof cover designed for outdoor furniture. This will protect it from snow, ice, and harsh winter elements.
B. Annual Professional Inspection
It is highly recommended to have a qualified HVAC technician or gas professional inspect your natural gas fire pit on an annual basis. They can:
Check for gas leaks.
Inspect gas lines and connections for wear and tear.
Clean and adjust the burner as needed.
Ensure all safety features are functioning correctly.
C. Cover Usage
Always use a high-quality, weather-resistant cover when the fire pit is not in use, especially during inclement weather or long periods of inactivity. This protects the stone, burner, and media from rain, snow, UV rays, and debris, significantly extending the life of your fire pit.
IV. Troubleshooting Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| No flame or weak flame | Gas supply off or low pressure | Ensure the gas valve is fully open. Check if other gas appliances are working. Consult Todds Services if the issue persists. |
| Burner ports blocked | Debris in ports | Clean burner ports with a soft brush or compressed air. |
| Igniter not sparking | Battery dead (if applicable) or igniter fouled | Replace igniter battery. Clean the igniter electrode gently with a soft cloth. |
| Soot or black residue on media | Incomplete combustion, often due to blocked ports or incorrect gas pressure | Clean burner ports. Consult a professional to check gas pressure. |
| Excessive smoke | Blocked ports or improper media placement | Clean burner ports. Ensure lava rocks/fire glass are not directly covering the burner holes. |
| Water pooling in burner pan | Inadequate drainage or excessive rain | Ensure drainage holes (if present) are clear. Use a cover when not in use. |
