Safety Information
Adherence to the following safety guidelines is crucial for safe assembly and use of the gazebo:
- Always follow the provided instructions for assembly, disassembly, and use.
- Ensure the gazebo is properly anchored to the wall and the ground. All necessary hardware for wall mounting is included.
- Keep children and pets away from the assembly area to prevent accidents.
- Do not adjust the height while the gazebo is occupied.
- Always inspect the gazebo before use, and tighten any loose bolts or screws.
- Do not hang heavy objects from the gazebo frame.
- In extreme weather conditions (e.g., severe storms, heavy snow beyond capacity), consider disassembling or taking additional precautions to secure the structure.
Assembly Instructions
The AECOJOY Lean-to Gazebo is designed for straightforward assembly. It is recommended that at least two adults participate in the assembly process. Refer to the detailed manual included in the packaging for step-by-step visual guides.
Key Assembly Considerations:
- Adjustable Height Range: The rear side of the gazebo offers a flexible height range from 6.5 ft (78 inches) to 9.8 ft (118 inches). This allows for adaptation to various installation needs, such as matching eaves or door frame heights.
- Wall-Mounted Design: This gazebo attaches securely to a wall, eliminating the need for rear support posts and improving structural stability. All necessary wall-mounting hardware is included.
- Anchoring: Proper anchoring to the ground is essential for stability, especially in windy conditions. The structure is designed to withstand winds up to 70 mph when correctly anchored.

Structural Components:
- Sun Panels: Heavily tinted panels provide UV protection and allow some light through.
- Aluminum Tubes: Crisscrossing aluminum tubes offer strong support for the roof panels, contributing to high load ratings.
- Multiple Keyholes & Triangle Structure: The design incorporates multiple keyholes and a triangular structure to enhance the stability of the frame.

Operation
The primary operational feature of this gazebo is its adjustable height. This allows you to customize the pitch and clearance of the roof to suit your specific needs and environment.
Adjusting Height:
- Ensure the area around the gazebo is clear of obstructions and people.
- Loosen the designated fasteners that secure the adjustable posts to the desired height. Refer to your assembly manual for specific fastener locations.
- Carefully raise or lower the rear side of the gazebo to the desired height within the 6.5 ft to 9.8 ft range. It is recommended to have at least two people for this operation.
- Once the desired height is achieved, securely tighten all fasteners to lock the posts in place. Verify that the structure is stable before use.
Note: Increasing the height of the rear side will decrease the distance between the front support posts and the wall. Conversely, lowering the height will increase this distance.

Maintenance
Regular maintenance will extend the lifespan and preserve the appearance of your AECOJOY gazebo.
Cleaning:
- Clean the roof panels and frame periodically with mild soap and water. Rinse thoroughly with clean water.
- Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish and materials.
- Remove any accumulated debris (leaves, branches) from the roof to prevent drainage issues and excessive load.
Seasonal Care:
- Snow Load Capacity: The hardtop roof is designed to handle up to 6 lbs/sq.ft, equivalent to approximately 7 inches of heavy snow. In areas with consistently heavy snowfall, it is advisable to regularly clear snow from the roof to prevent exceeding this capacity.
- Waterproof Performance: The sloped design and precision-engineered roofing ensure complete waterproofing. Regularly check for any blockages in the drainage system.
- Wind Resistance: When properly anchored, the gazebo can withstand winds up to 70 mph. Periodically check the integrity of all anchors and connections.

Troubleshooting
This section addresses common issues that may arise during assembly or use.
Common Issues and Solutions:
- Missing or Damaged Parts: If you find any parts missing or damaged upon unboxing, contact AECOJOY customer support immediately for replacements.
- Difficulty with Screw Alignment: Ensure all components are correctly oriented as per the manual. Do not overtighten screws until all parts are loosely fitted, then tighten progressively. A power drill may be used for stubborn connections, but exercise caution to avoid stripping screws.
- Roof Panel Alignment Issues: If roof panels do not fit perfectly, double-check the frame assembly for squareness. Minor adjustments to the frame may be necessary. In some cases, slight trimming of a panel edge might be required, but this should be a last resort and performed carefully.
- Water Leakage: Verify that all roof panels are correctly seated and sealed. Check for any gaps or damage to the panels. Ensure the sloped design allows for proper water runoff and that drainage channels are clear.
- Instability: Confirm that the gazebo is securely anchored to both the wall and the ground as instructed. Ensure all bolts and fasteners are tightened.
- Hardware Quality Concerns: If included washers or bolts seem insufficient, consider using fender washers or truss bolts with larger heads for better pressure distribution, especially for waterproof seals. Ensure any replacement hardware is suitable for outdoor use.
