When a standard flat-flange roof jack is installed on a sloped roof, a proper seal cannot be achieved without an adapter. This part bridges that gap. It fits a 4\/12 roof pitch, meaning for every 12 inches of horizontal run, the roof rises 4 inches. That is a common pitch found on residential homes across the country, making this adapter a frequently needed component in the field. HVAC technicians and installers rely on this type of adapter to complete direct-vent and power-vent furnace installations correctly on pitched roofs. Without the right adapter, the termination point may not sit flush, creating gaps that allow water intrusion, reduce draft performance, or cause premature equipment failure. The Miller 903895 eliminates those risks by providing a properly angled base that mates with the flat flange of the roof jack and aligns it to the slope of the roof surface. This allows the roof jack assembly to terminate cleanly through the roofline with a weathertight fit. HVAC professionals working on gas furnace installations, furnace replacements, or vent system upgrades will find this adapter essential when the existing or new roof jack uses a flat flange on a 4\/12 pitched roof. It is a straightforward, purpose-built component that ensures code-compliant and weather-resistant vent terminations. Keeping this part on hand reduces callbacks and saves time on the job site.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDesigned for flat-flange furnace roof jacks installed on sloped roofs\u003c\/li\u003e\n\u003cli\u003eFits a 4\/12 roof pitch for a flush, weathertight termination\u003c\/li\u003e\n\u003cli\u003eSimplifies gas furnace venting installations on common residential roof slopes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Miller 903895 Sloped Roof Jack Adapter provides a reliable solution for achieving a proper roof termination on 4\/12 pitched roofs when the furnace roof jack uses a flat flange.
