It is commonly referenced by the model designation SRJ1. This part connects the furnace vent system to the roof, allowing combustion gases to exit the building safely. HVAC technicians and service professionals use roof jacks like this one when installing or replacing vent terminations on CMF-series furnaces. The 104060000 measures 12 inches from the flange to the bottom of the roof jack. This measurement is critical during installation because the bottom end of the roof jack must hang below the ceiling line and connect to the vent pipe that runs up from the furnace. The outer double-wall construction measures 8 inches in diameter, providing durability and thermal separation between the hot flue gases and surrounding materials. The inner vent pipe size is 4 inches, which is the standard diameter used on most Nordyne CMF furnaces. The 4 inch vent pipe is not included and must be ordered separately. Installation adjustment is made by sliding the vent pipe up and down inside the roof jack to achieve the correct fit. This roof jack is designed for installation on a flat roof surface only. If your application involves a pitched roof, a sloped roof adapter corresponding to the specific pitch of the roof must be ordered separately. Sizing is determined by measuring the distance from the ceiling to where the flange rests on the roof surface. A replacement crown for this unit is available under part number 104360000. This roof jack is a direct-fit solution for technicians servicing or replacing vent components on Nordyne CMF furnaces and is a trusted part in commercial and residential HVAC vent system maintenance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFits most Nordyne CMF furnaces with 4 inch vent pipes\u003c\/li\u003e\n\u003cli\u003e12 inches from flange to bottom of roof jack for precise ceiling clearance sizing\u003c\/li\u003e\n\u003cli\u003eOuter double-wall construction measures 8 inches in diameter for added durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Miller 104060000 roof jack provides a reliable vent termination solution for Nordyne CMF furnaces, featuring a double-wall 8 inch outer diameter and 12 inch depth to accommodate standard ceiling installations on flat roof applications.\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: MILLER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 104060000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Designation\u003c\/strong\u003e: SRJ1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Furnace Series\u003c\/strong\u003e: Nordyne CMF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Pipe Inner Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Double-Wall Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange to Bottom Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoof Installation Type\u003c\/strong\u003e: Flat roof only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Crown Part Number\u003c\/strong\u003e: 104360000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Package Dimensions\u003c\/strong\u003e: 15 x 15 x 29 inches\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILLER","offers":[{"title":"Default Title","offer_id":51120887300402,"sku":"104060000","price":299.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304882211.webp?v=1777742435","url":"https:\/\/voomisupply.com\/products\/miller-104060000-nordyne-cmf-roof-jack-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
