Tjernlund Products VH1-4 Aluminum Hood

The Tjernlund VH1-4 is a professional-grade 4-inch aluminum vent hood engineered specifically for side wall vent systems and horizontal terminations of gas-fired equipment. This heavy-duty assembly is constructed from 20-gauge corrosion-resistant aluminum, ensuring a long service life even when exposed to high-temperature flue gases up to 550°F gross. Designed to maintain the structural integrity of the building’s exterior, the VH1-4 features an integrated heat shield that provides necessary clearance from combustible materials, making it a critical component for safe sidewall vent termination. The 9x9 inch flange and 8x8 inch rough-in dimensions allow for a secure fit, while the included mounting hardware streamlines the installation process for HVAC contractors. By effectively managing airflow and exhaust, this sidewall termination hood prevents moisture buildup and soot damage on exterior surfaces, maintaining both system performance and building aesthetics.

• Corrosion Resistance: Fabricated from 20-ga aluminum to withstand harsh exhaust environments and outdoor exposure.
• Integrated Heat Shield: Built-in protection ensures safe installation with proper clearances from combustible wall materials.
• System Compatibility: Explicitly designed as an approved termination for Tjernlund side wall systems and various horizontally vented appliances.
• Debris Protection: Includes a screened opening to prevent foreign material or pests from entering the vent pipe.
• Exterior Protection: Engineered to direct flue gases away from the structure, preventing stains and heat damage to siding.

What is the maximum temperature rating for this hood?
The VH1-4 is rated for vent systems where the flue gas temperature does not exceed 550°F gross at the point of termination.

Does it require a separate thimble for combustible walls?
This model includes an additional heat shield designed for built-in clearances, though installers must always verify local code requirements and the provided mounting template for specific penetration details.

Can this be used for intake air applications?
While primarily designed as an exhaust termination for power venters, its robust aluminum construction makes it suitable for various 4-inch horizontal air management applications.
