Ao Smith 100285331 Roof Jack Kit 12 Inches Length 7-12 Max Pitch

Product Description

The AO Smith 100285331 is a roof jack kit designed for water heater venting installations where the flue pipe exits through the roof. This kit is built for a 12 inches length configuration and supports a maximum pitch range of 7-12, making it well suited for moderate to steep residential and light commercial roof slopes. Roof jack kits are a critical component in any direct vent or atmospheric vent water heater installation. They create a weathertight seal where the vent pipe penetrates the roofline, protecting the structure from rain, wind, and debris intrusion. HVAC technicians and plumbing professionals rely on these kits to complete safe, code-compliant installations. The AO Smith 100285331 is engineered to work with AO Smith water heater systems and is a factory-matched replacement or new-install component, ensuring proper fit and performance. Correct pitch compatibility is essential when selecting a roof jack. A kit rated for 7-12 pitch handles roofs that rise 7 inches for every 12 inches of horizontal run, covering a wide range of common residential roof designs. Using the properly rated roof jack prevents gaps, improper flashing alignment, and potential water infiltration that can cause structural damage or venting hazards. This kit simplifies the installation process by providing the components needed to flash and seal the vent pipe at the roof deck. It is a go-to part for service technicians performing water heater replacement, new construction rough-in, or venting system upgrades. Keeping this kit on hand reduces callback risk and ensures a professional, lasting installation.
