Nordyne 903107 Roof Jack Extension
Optimizing a standard HVAC venting system often requires precise adjustments to the vertical stack height to clear local structural obstructions or meet specific residential building codes. The Nordyne 903107 Roof Jack Extension provides a rugged 18-inch internal roof jack extension designed to bridge the gap between your furnace or mobile home heating system and the exterior roof jack assembly. Engineered for rigorous duty cycles, this HVAC ventilation part features a concentric design with a 5-inch internal pipe diameter and an 8.25-inch outer diameter, ensuring seamless integration with existing furnace roof jack components without compromising draft integrity or exhaust pressure.
For contractors managing complex retrofits in manufactured or modular homes, the Nordyne 903107 is an essential OEM HVAC replacement part. It effectively extends the venting connection inside the home—below the ceiling line—to achieve the necessary elevation for effective flue gas discharge. By utilizing this 18" roof jack extension, you ensure ventilation system compatibility with Nordyne and Miller-brand furnaces while maintaining a secure, airtight seal. This furnace venting extension is crucial for tall wall or cathedral ceiling applications where standard lengths fail to reach the roofline, providing a professional-grade solution that withstands extreme thermal shifts.
- Universal Height Adjustment: Adds 18 inches of vertical reach to standard internal roof jacks, facilitating installation in high-ceiling environments.
- Concentric Flue Design: Matches standard 5" inner and 8.25" outer specifications for streamlined connection to existing residential venting stacks.
- OEM Reliability: Genuine Nordyne part ensures precise tolerances and fitment, reducing installation labor and preventing exhaust leaks.
- Strategic Internal Placement: Designed for use below the ceiling to safely extend the furnace flue to the main roof jack assembly.
Common Questions
What is the pipe diameter of the Nordyne 903107?
This internal extension is built with a 5-inch inner diameter for the exhaust pipe and an 8.25-inch outer diameter, consistent with standard residential HVAC venting standards.
Where should this extension be installed?
The 903107 is specifically designed as an internal extension. It should be used inside the living space—typically between the top of the furnace and the ceiling—and is not intended for attic or external roof-side installation.
Is this compatible with all mobile home furnace brands?
While designed primarily for Nordyne, Miller, and Intertherm systems, it works with most roof jack systems that share the 5" x 8.25" concentric specification. Always verify flue dimensions before purchasing.
