BROAN-NuTone MD8TU Damper
The BROAN-NuTone MD8TU is an 8-inch universal automatic make-up air damper designed to provide synchronized ventilation in high-performance residential kitchen environments. Engineered to meet IRC makeup air requirements, this pressure-sensing damper automatically opens when the range hood is activated, preventing negative air pressure and potential backdrafting of combustion appliances. The unit features a normally closed motorized damper construction, ensuring a tight seal to minimize energy loss when the system is inactive. Installation is streamlined via the included pressure sensor switch and 24VAC transformer, allowing for universal compatibility with any range hood brand or model. For contractors, the MD8TU offers a reliable solution for building code compliance in airtight modern homes where exhaust fan CFM exceeds 400. The heavy-duty galvanized steel housing and precision-engineered motor ensure long-term reliability in demanding HVAC applications.
Key Benefits- Ensures code compliance with International Residential Code (IRC) for makeup air.
- Universal design integrates with any ventilation hood regardless of brand using a pressure-sensing switch.
- Prevents negative pressure and dangerous backdrafting of gas water heaters or furnaces.
- Robust motorized damper closure reduces infiltration of outdoor air during idle periods.
- Simplifies installation with a complete kit including low-voltage transformer and necessary hardware.
Is the MD8TU compatible with non-Broan range hoods?
Yes, the MD8TU is a universal solution. It uses an auxiliary pressure switch to detect airflow in the exhaust duct, making it compatible with any brand or model of ventilation fan.
What gauge wire is required for the low-voltage connections?
Standard 18/2 thermostat wire is typically used to connect the 24VAC transformer, the pressure switch, and the damper motor actuators.
Where should the pressure sensor probe be installed?
For optimal accuracy, the sensor probe should be installed in the exhaust duct between the range hood discharge and the outlet, away from turbulent air zones like elbows or transitions.
