Ao Smith 100285412 Adjustable Roof Jack Kit 60 Inches Length 7/12 Max Pitch

Product Description

The AO Smith 100285412 is an adjustable roof jack kit designed for use with direct vent water heater installations. It provides a secure, weather-tight passage for venting systems through pitched roofs. This kit is compatible with AO Smith FMDV and FMHR series water heaters, making it a reliable choice for contractors and plumbers working on residential and light commercial installations. The adjustable design accommodates a wide range of roof slopes, from standard pitches up to a 7/12 maximum pitch, giving installers flexibility across many job sites. The kit extends from 32 inches up to 60 inches in length, allowing it to fit varying roof thicknesses and rafter depths without requiring custom cuts or additional adapters. Roof jack kits like this one are a critical component in any vented water heater installation. They create the proper flashing and flange interface between the vent pipe and the roof deck. A proper roof jack keeps rain, debris, and pests from entering the structure while maintaining the correct clearances required by local building codes. Without a well-fitted roof jack, the vent system is vulnerable to leaks and structural moisture damage over time. The AO Smith 100285412 is built to work with the specific vent pipe dimensions of the FMDV and FMHR product lines, ensuring a code-compliant and watertight fit. HVAC technicians and plumbers installing or replacing AO Smith water heaters will find this kit straightforward to work with. It is an OEM-specified component, which simplifies the approval process during inspections. Keeping the correct roof jack on hand reduces call-backs and ensures long-term installation integrity. This kit is an essential part of any complete direct vent water heater installation package.
