4. Setup & Installation
The Domi 12x20FT Lean-to Gazebo is delivered in 6 separate packages. A comprehensive installation guide is included with your purchase. Please follow the steps outlined in the guide carefully. For optimal results and safety, we recommend the following:
- Team Assembly: Assembly is significantly easier and safer with at least two people.
- Tool Recommendation: Using an Allen driver in a cordless drill can expedite the assembly process, as there are numerous screws.
- Screw Installation: Always hand-thread screws first before using a power driver to prevent cross-threading. A Phillips screwdriver can assist in aligning holes.
- Clearance for Assembly: Some screws are located on the back of the structure, requiring approximately one foot of clearance from the house wall during initial assembly. The gazebo can then be maneuvered into its final position.
- Support Poles: The essential support poles MUST be assembled in all conditions to ensure stability and safety.

6. Maintenance
Regular maintenance will extend the life and appearance of your gazebo:
- Cleaning the Frame: Wipe the aluminum frame with a soft cloth and mild soap and water. Rinse thoroughly and dry to prevent water spots. Avoid abrasive cleaners.

- Curtains and Netting: Curtains and netting can be removed for cleaning. Follow the care instructions on their labels. Store them in a dry place during off-season or extreme weather.
- Fastener Check: Annually, or after severe weather, check all bolts and screws to ensure they are tight. Re-tighten as necessary.
- Snow Removal: During winter, promptly remove heavy snow accumulation from the roof to prevent structural damage.
7. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty aligning holes during assembly | Manufacturing tolerances; parts not perfectly aligned. | Use a Phillips screwdriver to help align holes. For minor misalignments, gentle pressure or slight adjustments (e.g., careful bending) may be required. Avoid forcing parts. |
| Missing or damaged parts upon delivery | Shipping damage or packaging error. | Contact Domi customer support immediately with your purchase details and photos of damaged parts. Refer to the 'Support' section for contact information. |
| Gazebo feels unstable after assembly | Fasteners not fully tightened; support poles not installed; improper anchoring. | Ensure all bolts and screws are securely tightened. Verify that the essential support poles are correctly installed. Ensure the gazebo is properly anchored to a stable surface. |
| Water accumulation on the roof or poor drainage | Gutters are clogged with debris. | Regularly inspect and clear the gutter system of leaves, twigs, and other debris to ensure proper water flow. |
| Curtains/netting detach in windy conditions | Velcro attachments may not be sufficient for strong winds. | Ensure curtains are securely tied back or fully closed. Consider adding additional tie-down points or clips for extra security in high winds. |
