1. Important Safety Information
Please read and understand all instructions before assembly and use. Failure to follow these instructions may result in serious injury or property damage.
- Snow and Wind Ratings: Check snow capability and wind rating specifications. This gazebo has a Snow Load capacity of 3300 LBS and a Wind Rate of 40 MPH.
- Installation Team: Assembly requires a minimum of 2-4 people. It is recommended that 2-4 people work together to assemble the gazebo, which typically takes 3-5 hours.
- Tools and Protection: Prepare necessary tools such as ladders and gloves for installation.
- Waterproofing: The waterproof performance of the roof system is directly related to the tightness of the installation. Ensure all connections are tight and secure.
- Heat Warning: Due to the dark color of the item and the high heat conductivity of aluminum, the gazebo may heat quickly under direct sunlight and reach high temperatures. This temperature depends directly on sunlight intensity.
- Dimensions: The given dimension of the gazebo describes the measurements from eave edge to eave edge, not from pole to pole. Refer to the specification sheet for detailed dimensions.
- Anchoring: Ensure the four anchoring stands are sturdily anchored into the ground. It is not recommended to permanently anchor this gazebo to a hard surface such as a wood deck or concrete floor without proper anchoring hardware.
- Local Regulations: Consult your local city, municipality, and applicable HOA guidelines before purchasing for guidance on building codes and/or zoning requirements in your area. This structure may require a license.
- Flame Resistance: Keep all flame and heat sources away from the tent fabric. This tent is made with fabric that meets CPAI-84 specification for flame resistance. It is not fireproof. The fabric will burn if left in continuous contact with any flame source. The application of any foreign substance to the tent fabric may render the flame-resistance properties ineffective.

4. Operating Instructions
4.1. Using Curtains and Netting
The gazebo features a double-track system for its curtains and netting. This allows for flexible use:
- Privacy and Sun Protection: Use the solid curtains for privacy or to block direct sunlight. They can be zipped together for full enclosure.
- Insect Protection: Deploy the mosquito netting to keep insects out while maintaining airflow and visibility.
- Combined Use: Both the curtains and netting can be used simultaneously or independently.
- Securing Curtains: When not in use, tie back the curtains and netting to the posts using the provided straps to prevent them from flapping in the wind.

5. Maintenance
Regular maintenance will extend the life and appearance of your MELLCOM Hardtop Gazebo.
- Cleaning the Roof: Periodically clean the galvanized steel roof panels to remove leaves, debris, and dirt. Use a soft brush or cloth with mild soap and water. Rinse thoroughly.
- Frame Care: Inspect the aluminum frame for any signs of wear or damage. Clean with a damp cloth and mild detergent. Avoid abrasive cleaners.
- Curtains and Netting: The fabric curtains and netting can be spot cleaned with mild soap and water. For deeper cleaning, follow the care instructions on the fabric tags. Ensure they are completely dry before storing or zipping up for extended periods to prevent mildew.
- Hardware Check: Regularly check all bolts, screws, and connections to ensure they remain tight. Tighten any loose hardware to maintain structural integrity.
- Winter Preparation: While the galvanized steel roof is designed to withstand snow, it is advisable to clear heavy snow accumulation to prevent excessive stress on the structure. Store curtains and netting indoors during harsh winter conditions to prolong their lifespan.
