Operating Instructions
Adjusting Sidewalls
The gazebo features a dual rail system for its sidewalls, allowing for flexible configuration:
- Fully Open: Slide both the nettings and curtains to the side and secure them with the attached ties for an open-air experience.
- Semi-Open: Close only the mosquito nettings to keep insects out while maintaining airflow and visibility.
- Fully Closed: Close both the mosquito nettings and privacy curtains for maximum privacy and protection from sun or light rain.

Using Integrated Hooks
The top of the gazebo is equipped with J-shaped hooks. These can be used to hang lightweight items such as decorative lights or small fans to enhance your outdoor comfort and ambiance.

Maintenance
- Cleaning the Frame: Clean the aluminum frame with a mild soap and water solution. Rinse thoroughly and dry to prevent water spots. Avoid abrasive cleaners.
- Cleaning the Roof: The galvanized steel roof can be cleaned with a soft brush and water. For stubborn dirt, use a mild detergent. Ensure proper drainage to prevent water pooling.
- Cleaning Curtains and Nettings: The fabric curtains and nettings can be spot cleaned with mild soap and water. For deeper cleaning, they may be removed and hand washed or machine washed on a gentle cycle with cold water. Air dry completely before reattaching.
- Seasonal Care: In areas with heavy snowfall, it is recommended to regularly clear snow from the roof to prevent structural damage. During periods of extremely high winds, consider temporarily removing the curtains and nettings or, if necessary, partially disassembling the gazebo.
- Regular Inspection: Periodically check all bolts and connections to ensure they remain tight. Inspect the frame for any signs of wear or damage.

Troubleshooting
- Wobbly Frame: Ensure all bolts are fully tightened. Check that the gazebo is on a level surface and properly anchored.
- Leaking Roof: Verify that all roof panels are correctly installed and sealed. Check for any gaps or loose connections.
- Curtains/Nettings Not Sliding Smoothly: Inspect the dual tracks for obstructions or debris. Ensure the fabric is not caught or twisted. Clean the tracks if necessary.
- Missing Parts: If you discover missing parts during assembly, do not proceed. Contact VIWAT customer service immediately for assistance.
