Miller 104060000 Nordyne Cmf Roof Jack 12 Inches

Product Description

The Miller 104060000 is a roof jack designed for use with Nordyne CMF furnaces. 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.

• Fits most Nordyne CMF furnaces with 4 inch vent pipes
• 12 inches from flange to bottom of roof jack for precise ceiling clearance sizing
