York Gaskets

Overview

The YORK s1-4000-7141/c is a furnace roof jack designed to vent combustion gases from residential gas furnace installations through the roof. This unit accommodates a floor-to-flange height range of 99 inches to 120 inches, making it suitable for installations with varying ceiling heights or roof pitches. The roof jack provides a weathertight penetration point where the flue passes through the roof deck, protecting the structure from moisture intrusion and maintaining proper draft. Licensed HVAC technicians install this component as part of a complete B-vent or single-wall vent system termination. This roof jack fits standard residential furnace venting applications where the floor-to-flange measurement falls between 99 inches and 120 inches. It is used in new construction and replacement venting projects where the existing flue termination height must be matched or a new penetration is being established. The adjustable range reduces the need for field cutting or custom fabrication in most standard residential installations.
