2.3 Assembly Steps
Follow the detailed diagrams provided in the included assembly guide. Pay close attention to part numbers and orientations. Below are general guidelines:
- Unpack and Identify Parts: Carefully unpack all components and verify against the parts list in your assembly guide. Organize parts by type and label.
- Assemble the Base Frame: Connect the horizontal and vertical frame components to form the base structure. Ensure all connections are secure but do not fully tighten bolts until the entire frame is assembled.
- Install Support Posts: Attach the main support posts to the base frame.
- Construct the Roof Frame: Assemble the upper roof frame structure. This often involves multiple smaller components.
- Attach Roof Panels: Carefully install the galvanized steel roof panels onto the roof frame. Ensure panels overlap correctly for water drainage. Note: Some users have reported difficulty aligning holes for roof panels; ensure the roof frame is correctly oriented before attaching panels.
- Install Netting and Curtains: Attach the netting and curtains to the designated tracks on the gazebo frame.
- Final Tightening and Anchoring: Once all components are in place and aligned, fully tighten all bolts. Securely anchor the gazebo to the ground using the pre-drilled base and appropriate ground stakes or anchors (not always included, may need to be purchased separately depending on surface).


3. Operating Features
3.1 Double Roof Design and Ventilation
The gazebo features a double-tier galvanized steel roof designed to reduce air pressure and promote air circulation, ensuring a comfortable environment. This design also enhances stability against wind.

3.2 Drainage System
The galvanized steel roof is equipped with a drainage system that directs rainwater away from the interior. Water flows from the edges of the roof to the frame and poles, preventing accumulation.

3.3 Netting and Curtains
The gazebo includes a fully enclosed zippered double side wall system with netting and privacy curtains. These can be easily opened or closed using the two-rail system. The mesh netting provides protection from insects while allowing airflow, and the polyester privacy curtains offer shade and privacy.

3.4 Integrated Hooks
A "U"-shaped hook is located in the center of the steel roof. This hook can be used to hang lightweight items such as lamps or fans.

4. Maintenance
4.1 General Care
- Regularly inspect all bolts and connections to ensure they remain tight. Re-tighten as necessary.
- Check the ground anchors periodically to ensure the gazebo remains securely fastened.
- Inspect the roof panels for any signs of damage or loose connections, especially after strong winds or storms.
4.2 Cleaning
- Frame: Clean the aluminum frame with a mild soap and water solution. Rinse thoroughly with clean water and dry with a soft cloth. Avoid abrasive cleaners or harsh chemicals.
- Roof Panels: The galvanized steel roof can be cleaned with a soft brush or cloth and mild soapy water. Rinse well.
- Netting and Curtains: These can typically be spot cleaned with mild soap and water. For deeper cleaning, refer to any specific care labels if available. Ensure they are completely dry before storing or closing for extended periods to prevent mildew.
5. Troubleshooting
5.1 Assembly Difficulties
- Parts not fitting/aligning: Double-check the assembly diagrams for correct orientation of parts. Ensure all bolts are only hand-tightened until the entire section is assembled, then fully tighten. If parts are bent or damaged upon arrival, contact customer support.
- Missing hardware: Verify against the parts list. If hardware is missing, contact customer support for replacements.
5.2 Water Leaks
- Roof leaks: Ensure all roof panels are correctly overlapped and securely fastened. Check for any gaps or improperly sealed areas. Applying a weather-resistant sealant to bolt holes or seams may help if minor leaks persist.
- Drainage issues: Ensure the drainage channels are clear of debris.
5.3 Stability Concerns
- Gazebo movement: Re-check all ground anchors and ensure they are firmly secured. Consider using heavier-duty anchors if the gazebo is installed in a windy area or on a soft surface.
- Snow load: The gazebo is designed for general outdoor use. In regions with heavy snowfall, it is crucial to regularly clear snow from the roof to prevent structural damage or collapse. The roof is not designed to withstand significant snow accumulation.
