2. Safety Information

WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.

• Always wear appropriate personal protective equipment (PPE) such as gloves and eye protection during installation.
• Ensure the installation area is well-ventilated.
• Do not use this product for applications other than those specified (bathroom venting).
• This duct is fire-retardant with a maximum operating temperature of 250°F. Do not expose to temperatures exceeding this limit.
• Keep away from sharp objects that could puncture or damage the duct.
• Consult local building codes and regulations for proper venting practices.

3. Setup and Installation

The LamaFlex Aluminum Flex Duct is designed for flexible installation. Follow these steps for proper setup:

1. Unpack the Duct: Carefully remove the duct from its packaging. Extend the duct to its full 50-foot length, ensuring there are no kinks or twists.
2. Prepare the Connection Points: Ensure the inlet and outlet points for your bathroom venting system are clean and free of debris. The duct is 4 inches in diameter, so ensure your connection points match this size.
3. Attach to Vent Fan/Outlet: Securely attach one end of the duct to the exhaust port of your bathroom vent fan using appropriate clamps (not included). Ensure a tight seal to prevent air leakage.
4. Route the Duct: Carefully route the duct to the exterior exhaust point. Avoid sharp bends or excessive compression, which can restrict airflow. Maintain the shortest and straightest path possible for optimal performance.
5. Attach to Exterior Vent Cap: Securely attach the other end of the duct to the exterior vent cap using appropriate clamps. Ensure the vent cap is properly installed and allows for unobstructed exhaust.
6. Inspect Connections: Double-check all connections to ensure they are secure and airtight.

Note: This duct is suitable for bathroom venting only. Do not use for dryer venting or other high-temperature applications beyond its specified limits.

4. Operating Instructions

Once properly installed, the LamaFlex Aluminum Flex Duct operates passively as part of your bathroom ventilation system. Its function is to channel moist and stale air from the bathroom to the exterior of the building.

• Ensure your bathroom exhaust fan is functioning correctly to draw air through the duct.
• Periodically check the exterior vent cap to ensure it is not obstructed by debris, snow, or ice, which could impede airflow.
• The duct is designed for a maximum air handling capacity of 5,000 FPM (feet per minute). Ensure your ventilation system operates within appropriate airflow parameters.

5. Maintenance

Regular maintenance helps ensure the longevity and efficiency of your LamaFlex Aluminum Flex Duct.

• Annual Inspection: At least once a year, inspect the entire length of the duct for any signs of damage, tears, or disconnections.
• Check for Obstructions: Ensure the duct is free from internal obstructions such as dust, lint (though less common in bathroom venting than dryer venting), or pest nests.
• Clean Exterior Vent Cap: Regularly clean the exterior vent cap to remove any accumulated debris that might restrict airflow.
• Repair or Replace: If any damage is found, repair or replace the affected section of the duct immediately to maintain proper ventilation and prevent moisture buildup.
