2. Safety Information
- Secure Installation: Always secure the gazebo to a stable foundation to prevent it from tipping over in windy conditions.
- Weather Conditions: Do not use the gazebo in extreme wind conditions.
- Assembly: Always follow the assembly instructions carefully to avoid injury.
- Climbing: Do not stand, lean, or climb on the gazebo frame or roof.
3. Setup and Assembly
Assembly of the domi outdoor living Hardtop Gazebo requires careful attention to detail and may benefit from multiple individuals. All necessary screws and tools are included. It is recommended to lay out all parts and familiarize yourself with the assembly manual before beginning.
3.1. Pre-Assembly Considerations
- Location: Choose a level and stable surface for installation. Ensure adequate clearance around the gazebo.
- Anchoring: The gazebo must be securely anchored to the ground. Anchoring bolts are needed (not included). Consider pouring concrete footings for enhanced stability, especially in windy areas.
- Tools: While basic tools are provided, a power drill driver with 4mm and 6mm hex bits can significantly speed up assembly.
- Assistance: While some steps can be done solo, having 2-3 people is highly recommended for lifting the main frame and roof structure.
3.2. Assembly Steps Overview
- Unpack and Organize: Carefully unpack all boxes and organize components by their labels (e.g., D1, E1, U1, W3). The gazebo typically arrives in multiple large boxes.
- Base Frame Assembly: Assemble the main beams and posts on the ground. Attach all brackets as indicated in the manual.
- Vertical Frame Erection: With assistance, lift the side beams and posts to their standing position. Connect the corner assemblies using the designated screws.
- Square the Structure: Measure diagonally between posts (corner to corner) to ensure the structure is square. Measurements should be within half an inch of each other.
- Roof Support Installation: Attach the four N1 supports to the K header before lifting. Secure the main roof supports, then add the remaining supports (N, N2, M). Install the four M corner supports last.
- Roof Panel Installation: Install the galvanized steel roof panels. Ensure plastic tabs (Z series parts) are securely in place to prevent leaks. Silicone adhesive or masking tape can assist in holding them during installation.
- Final Tightening: Do not fully tighten all roof supports or frame bolts until the entire roof assembly is complete to allow for minor adjustments.
- Curtains and Netting: Install the double-track system for the removable curtains and netting.

4.1. Curtains and Netting
The gazebo includes a double-track system for both breathable netting and privacy curtains. These can be easily opened, closed, or tied back as needed.
- Netting: The mesh netting can be zipped up to provide a barrier against mosquitoes and other insects while allowing air circulation.
- Privacy Curtains: The removable curtains offer additional privacy and protection from UV rays. They can be zipped closed for full enclosure or tied back to open up the space.

4.2. Drainage System
The built-in drainage system is designed to collect rainwater from the roof and channel it down through the columns to the ground, preventing water accumulation and ensuring a dry space underneath.

5. Maintenance
- Cleaning Frame: Clean the aluminum frame with mild soap and water. Avoid abrasive cleaners that could damage the finish.
- Cleaning Roof: The galvanized steel roof can be cleaned with a soft brush and water to remove debris and maintain its appearance.
- Curtains and Netting: Remove and clean curtains and netting periodically according to fabric care instructions. Ensure they are completely dry before storing to prevent mildew.
- Hardware Check: Periodically check all screws and connections to ensure they remain tight and secure.
- Winter Care: While the galvanized steel roof is designed to withstand heavy snowfall, it is advisable to clear excessive snow accumulation to prolong the lifespan of the gazebo.
6. Troubleshooting
- Gazebo Instability: If the gazebo feels unstable, ensure all anchoring points are secure and all frame bolts are tightened. Re-check the squareness of the base frame.
- Water Leaks: Inspect roof panel seams and ensure all plastic clips are correctly installed and sealed. Apply additional sealant if necessary.
- Curtains/Netting Sticking: Clean the tracks and ensure no debris is obstructing the sliders. Lubricate tracks with a silicone spray if needed.
- Difficulty Zipping: Ensure zippers are clean and free from obstructions. Apply a zipper lubricant if they are stiff.
