Barometric draft controls regulate flue draft by allowing dilution air to enter the vent system, maintaining consistent draft pressure across varying atmospheric and stack conditions. This prevents over-drafting, which can cause short cycling, heat loss, and combustion inefficiency. The mgi-8 includes an integrated collar for connection to standard round flue pipe. It is installed by licensed HVAC technicians and heating contractors as part of a vented gas appliance system.\u003c\/p\u003e\n\u003cp\u003eThis barometric draft damper is intended for use on natural gas-fired heating equipment vented through conventional B-vent or single-wall metal flue pipe. Typical applications include residential and light commercial gas furnaces, boilers, and water heaters that require passive draft regulation. The 8-inch size fits standard 8-inch round flue pipe collars. It is suited for installations where stable, controlled flue draft is required to meet appliance manufacturer and code requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-inch diameter fits standard round flue pipe connections\u003c\/li\u003e\n  \u003cli\u003eIntegrated collar simplifies connection to existing vent pipe\u003c\/li\u003e\n  \u003cli\u003eDesigned for natural gas appliance venting systems\u003c\/li\u003e\n  \u003cli\u003ePassive barometric operation requires no electrical power\u003c\/li\u003e\n  \u003cli\u003eRegulates flue draft to prevent over-drafting and heat loss\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style barometric draft control for natural gas-fired residential and light commercial heating appliances vented with 8-inch round flue pipe.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified heating contractor in accordance with the International Fuel Gas Code (IFGC) and local authority requirements. Shut down and allow the heating appliance and flue system to cool completely before beginning installation. The damper must be mounted in the horizontal flue run between the appliance and the chimney, typically within the first few feet of the appliance flue collar. Verify that the damper swings freely and is plumb after installation before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlue Pipe Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Standard Barometric Draft Damper Control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar\u003c\/strong\u003e: Included\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: mgi-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51233395966258,"sku":"MGI-8","price":236.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629045.jpg?v=1780098950","url":"https:\/\/voomisupply.com\/products\/honeywell-mgi-8-barometric-draft-damper-8-inch-gas","provider":"Voomi Supply","version":"1.0","type":"link"}
