It serves as the exterior endpoint of a direct vent combustion system, allowing flue gases to exhaust while simultaneously drawing combustion air from outside. The cap mounts at the top of a vertical vent run and is designed for use by licensed HVAC technicians and heating contractors working on sealed-combustion appliances. Its high-wind design resists backdrafting and pressure fluctuations that can disrupt burner operation in exposed rooftop or elevated installations.\u003c\/p\u003e\u003cp\u003eThis termination cap is intended for vertical direct vent applications on residential and light commercial heating equipment. Direct vent systems use a sealed, two-pipe arrangement — one pipe for combustion air intake and one for exhaust — making the termination cap a critical component for proper system pressure balance and draft performance. It is suited for rooftop terminations where sustained or gusting winds are a common site condition.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-wind design resists backdraft and pressure reversal at the termination point\u003c\/li\u003e\n\u003cli\u003eVertical termination orientation for rooftop or elevated vent exits\u003c\/li\u003e\n\u003cli\u003eDesigned for sealed-combustion direct vent systems requiring balanced flue and air pathways\u003c\/li\u003e\n\u003cli\u003eDurable construction suitable for exterior weather exposure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation termination cap for direct vent vertical vent systems using a 5-inch vent configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with the appliance manufacturer instructions and applicable codes including the International Fuel Gas Code. Shut down and de-energize the connected heating appliance completely before servicing any vent termination components. Ensure the termination cap is secured and sealed against weather infiltration at the roof penetration point. Verify clearances to roof surface, adjacent walls, and air intakes meet local code and manufacturer requirements before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Direct Vent Vertical Termination\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWind Rating\u003c\/strong\u003e: High Wind\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: METAL-FAB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MF-5DVT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"METAL-FAB","offers":[{"title":"Default Title","offer_id":51672476844338,"sku":"MF-5DVT","price":162.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e178eee733aae9a78b64c94b893ba87c.jpg?v=1787967902","url":"https:\/\/voomisupply.com\/products\/metal-fab-mf-5dvt-direct-vent-vertical-termination","provider":"Voomi Supply","version":"1.0","type":"link"}
