This heavy-duty assembly is constructed from 20-gauge \u003cstrong\u003ecorrosion-resistant aluminum\u003c\/strong\u003e, 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 \u003cstrong\u003eheat shield\u003c\/strong\u003e that provides necessary \u003cstrong\u003eclearance from combustible materials\u003c\/strong\u003e, making it a critical component for safe \u003cstrong\u003esidewall vent termination\u003c\/strong\u003e. 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 \u003cstrong\u003esidewall termination hood\u003c\/strong\u003e prevents moisture buildup and soot damage on exterior surfaces, maintaining both system performance and building aesthetics.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion Resistance:\u003c\/strong\u003e Fabricated from 20-ga aluminum to withstand harsh exhaust environments and outdoor exposure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Heat Shield:\u003c\/strong\u003e Built-in protection ensures safe installation with proper clearances from combustible wall materials.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e Explicitly designed as an approved termination for Tjernlund side wall systems and various horizontally vented appliances.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDebris Protection:\u003c\/strong\u003e Includes a screened opening to prevent foreign material or pests from entering the vent pipe.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExterior Protection:\u003c\/strong\u003e Engineered to direct flue gases away from the structure, preventing stains and heat damage to siding.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum temperature rating for this hood?\u003c\/strong\u003e\u003cbr\u003e\nThe VH1-4 is rated for vent systems where the flue gas temperature does not exceed 550°F gross at the point of termination.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it require a separate thimble for combustible walls?\u003c\/strong\u003e\u003cbr\u003e\nThis 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan this be used for intake air applications?\u003c\/strong\u003e\u003cbr\u003e\nWhile primarily designed as an exhaust termination for power venters, its robust aluminum construction makes it suitable for various 4-inch horizontal air management applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
