Draft hoods are critical safety and performance components in natural draft gas boilers. They sit at the flue outlet of the boiler and serve as the connection point between the boiler's combustion chamber exhaust and the vent stack or chimney. Their primary function is to regulate the flow of flue gases leaving the heat exchanger, prevent backdraft from entering the combustion zone, and dilute flue gases with room air to reduce the risk of dangerous pressure fluctuations traveling back into the burner assembly. Without a properly functioning draft hood, negative pressure events in the vent system can disrupt burner operation, cause flame rollout, or allow combustion byproducts to spill into the mechanical room. The Weil-McLain wm450021245 is a direct-fit replacement hood engineered specifically for CG, CGa, and CGx boiler models, ensuring proper alignment with the flue collar and consistent sealing against the boiler jacket. HVAC technicians and boiler service professionals working on Weil-McLain residential and light commercial heating systems rely on OEM components like this to restore safe venting performance and meet code compliance requirements. At 16 inches in length, 16 inches in width, and 28 inches in height, this draft hood is sized to match the designated boiler configurations without modification. Weighing 9 pounds, it is manageable for single-technician installation. This part is the correct choice for restoring draft control on Weil-McLain CG series boilers during routine maintenance, service calls, or full boiler refurbishments.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDesigned specifically for Weil-McLain CG, CGa, and CGx boiler series for direct OEM-fit replacement\u003c\/li\u003e\n\u003cli\u003eStabilizes exhaust airflow and prevents backdraft from disrupting burner operation\u003c\/li\u003e\n\u003cli\u003eDimensions of 16 inches x 16 inches x 28 inches ensure proper fit to designated flue collar openings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Weil-McLain wm450021245 Draft Hood provides reliable exhaust management and backdraft protection for CG, CGa, and CGx boilers, making it a dependable OEM replacement for HVAC service professionals maintaining Weil-McLain heating systems.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WEIL-MCLAIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: wm450021245\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Boiler Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Type\u003c\/strong\u003e: Draft Hood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Boiler Series\u003c\/strong\u003e: CG, CGa, CGx\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEIL-MCLAIN","offers":[{"title":"Default Title","offer_id":51120917971250,"sku":"WM450021245","price":317.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304885046.webp?v=1777743283","url":"https:\/\/voomisupply.com\/products\/weil-mclain-wm450021245-draft-hood-cg-cga-cgx-boilers","provider":"Voomi Supply","version":"1.0","type":"link"}
