The unit ships with an integral collar sized at 10 inches for direct connection to a single-wall vent connector. Barometric draft dampers maintain consistent negative draft pressure by allowing dilution air into the breaching, protecting the appliance from over-draft or under-draft conditions that reduce efficiency and can cause combustion problems. Licensed HVAC technicians and plumbers install this control as part of a code-compliant venting system on appliances fired by natural gas, oil, wood, or coal.\u003c\/p\u003e\n\u003cp\u003eThe mgii-10 is suited for residential and light-commercial applications where a 10-inch vent connector exits a gas-fired furnace or boiler, an oil-fired unit, or a solid-fuel appliance burning wood or coal. The integral collar simplifies field installation by eliminating a separate adapter fitting. This damper is appropriate for use on B-vent and single-wall connectors that route combustion products to a masonry chimney or listed chimney liner.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-inch collar size for direct fit to matching vent connector diameter\u003c\/li\u003e\n  \u003cli\u003eCompatible with natural gas, oil, wood, and coal-fired appliances\u003c\/li\u003e\n  \u003cli\u003eBarometric swing-door design passively regulates flue draft without electronics or power\u003c\/li\u003e\n  \u003cli\u003eIntegral collar reduces installation hardware and saves field time\u003c\/li\u003e\n  \u003cli\u003eStandard construction suitable for residential and light-commercial venting systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation barometric draft damper for 10-inch vent connectors on natural gas, oil, wood, and coal-fired heating appliances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with NFPA 54, NFPA 31, and local mechanical codes. Shut down and allow the appliance to cool completely before working on the venting system. Position the damper in the vent connector between the appliance flue collar and the chimney entrance, following the appliance and damper manufacturer orientation requirements. Do not install a barometric damper on a direct-vent or sealed-combustion appliance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Compatibility\u003c\/strong\u003e: Natural gas, oil, wood, coal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Barometric draft damper\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mgii-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51233366606130,"sku":"MGII-10","price":390.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629048.jpg?v=1780098521","url":"https:\/\/voomisupply.com\/products\/honeywell-mgii-10-barometric-draft-damper-10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
