Cast iron construction provides durability and resistance to high-temperature flue gases, making it well suited for use in gas, oil, or solid-fuel appliance venting systems. This damper is typically installed by HVAC technicians or plumbers during new installations or service calls where airflow control within a vent or flue is required.\u003c\/p\u003e\n\u003cp\u003eThe BM0052-A is used in round duct or flue vent applications with a 7-inch diameter opening. It is appropriate for residential furnaces, water heaters, boilers, and similar appliances that exhaust through a B-vent or single-wall metal vent connector. This part suits scenarios where a manual or gravity-operated damper blade is needed to limit backdraft or control draft when the appliance is not in operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch diameter fits standard round vent and flue connector openings\u003c\/li\u003e\n  \u003cli\u003eCast iron construction withstands elevated flue gas temperatures\u003c\/li\u003e\n  \u003cli\u003eDamper blade controls draft and reduces heat loss when appliance is off\u003c\/li\u003e\n  \u003cli\u003eSold individually; packaged 12 units per case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation damper for 7-inch round vent connectors in residential and light commercial 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 local mechanical codes and IFGC requirements. Shut off and lock out the appliance and allow the venting system to cool fully before handling any flue components. The damper should be oriented so the blade pivots freely and the shaft is accessible for inspection. Do not install in an orientation that restricts blade movement or traps condensate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.32 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: IMPERIAL MFG GROUP USA INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BM0052-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":51559851131186,"sku":"BM0052-A","price":97.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b753744d5f4aadad3d50ae62f8b0a55d_b24928f1-a663-4bd1-8623-df1677ffadb5.jpg?v=1786442665","url":"https:\/\/voomisupply.com\/products\/imperial-mfg-group-usa-inc-bm0052-a-cast-iron-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
