Temp Vent Series 5 Automatic Crawl Space Vent

Temp-Vent Series 5 Automatic Foundation Vent (Two Piece Construction)

Installation Instructions for the TV Series 5 Temp Vent

This vent requires drilling for installation and uses 4 screws, anchors, and spring clips (included). It does not use hex bolts like the Series 6 Crawl Space Vent .

Note: These are the original Automatic Temp-Vents (patented in the 1960s). Many competing vents are lower-quality clones with shorter warranties. Temp-Vent products are built with higher-quality materials and backed by a longer warranty.

Protect Your Foundation and Crawl Space

Help protect your home’s foundation with Temp-Vent. Proper foundation ventilation is essential to prevent moisture buildup that can lead to costly structural damage.

Temp-Vent foundation vent systems help reduce conditions that lead to mold, mildew, fungi, damp rot, and unhealthy air.

But there’s more.

Termites are attracted to warm, moist, stagnant air environments commonly found in crawl spaces and unfinished basements. Temp-Vent foundation vents improve airflow, helping reduce moisture and make these areas less attractive to pests.

Think of it as a crawl space dehumidifier—no drain or electricity required.

Crawl Space Ventilation Guidelines

For best performance, vents should be installed on all sides of the foundation to create cross-ventilation and consistent airflow.

• Install one vent every 8–10 feet along the foundation wall
• Building codes typically require 1 sq. ft. of ventilation per 150 sq. ft. of crawl space
• Each vent provides approximately 50 sq. in. of net free airflow
• Recommended: 1 vent per 50 sq. ft. of crawl space

For crawl spaces with polyethylene covering 80–90% of the ground:

• 1 sq. ft. of ventilation per 500 sq. ft. of crawl space
• Minimum of 4 vents required for cross ventilation
• Recommended: 1 vent per 500 sq. ft.

Automatic Temperature-Controlled Operation

Temp Vent Automatic Foundation Vents use a temperature-sensitive coil to open and close automatically.

• Fully open at approximately 72°F
• Fully closed at approximately 38°F

Unlike manual vents, these automatically adjust year-round, improving energy efficiency and reducing maintenance.

Installation Tips

• Install one vent every 8–10 feet
• Place vents within 3 feet of each corner
• Use at least 4 vents for proper cross-ventilation
• Keep vents clear of dense shrubbery
