Nutone 349BR Powered Attic Ventilator 1000 Cfm Brown

Product Description

The NUTONE 349BR is a roof-mounted powered attic ventilator designed to exhaust hot air and moisture from residential attic spaces. Driven by a 4.0-amp motor, it delivers up to 1000 CFM of airflow through a steel dome housing in a brown finish. The unit mounts directly to the roof deck and works in conjunction with soffit or gable vents to create a continuous airflow path. HVAC technicians and roofing contractors install this type of ventilator to reduce attic heat buildup, which lowers cooling loads on the living space below. The four-blade steel fan and metal dome construction are built for year-round outdoor exposure.

This ventilator is suited for residential attic applications where mechanical exhaust is needed to supplement passive ventilation. It is appropriate for sloped roof installations on single-family homes and light residential structures. The brown finish blends with common roofing materials. No built-in timer and no automatic shutoff are included, so operation is controlled by a separate switch or thermostat wired by the installer.

Key Features

• 1000 CFM airflow capacity for effective attic heat and moisture removal
• 4.0-amp motor provides consistent fan performance
• Four-blade steel fan for durable, high-volume air movement
• Metal dome housing in brown finish suits standard residential rooflines
• Roof-mount design installs directly to roof deck
• No automatic shutoff or built-in timer - external control required

Compatibility

Designed as an OEM-style roof-mounted powered attic ventilator for residential sloped-roof installations where a direct-mount exhaust fan is required.

Installation Notes

Installation is typically performed by a licensed electrician or HVAC technician following NEC requirements for outdoor-rated electrical connections. Disconnect and lock out power at the breaker before wiring the unit. The ventilator requires a properly flashed roof curb or built-in flashing skirt to prevent water intrusion - follow local building code requirements for roof penetration and sealing. An external thermostat or wall switch should be installed to control operation since no automatic shutoff is included.
