Adjustable Furnace Venting for Deeper Sloped-Roof Installations
A 27-to-47-inch roof jack creates the required outdoor-air and exhaust connection.
The Intertherm 903663 is an adjustable manufactured-home furnace roof jack with a 27-to-47-inch working range. Its nominal 2.5/12 sloped flashing is designed for compatible pitched-roof installations requiring more reach than shorter roof-jack assemblies.
Intertherm, formerly marketed under the Revolv name, uses this roof jack to supply outdoor combustion air and safely discharge furnace exhaust. Its telescoping construction allows the installer to match the measured roof cavity, while the flashing and termination components support a weather-resistant installation.
- 27-to-47-inch adjustment: Accommodates moderate-to-deep roof cavities.
- Nominal 2.5/12 sloped flashing: Supports installation through an appropriate pitched roof.
- Combustion-air supply: Brings outside air to the compatible furnace.
- Furnace exhaust pathway: Directs combustion products above the roof.
- Telescoping construction: Allows precise adjustment within the listed range.
- Integrated roof components: Support correct alignment and weather sealing.
- Compatible applications: Listed for approved R, MG1, and M5S furnace families.
Choose the 903663 when the compatible furnace, roof pitch, and measured cavity require a 27-to-47-inch sloped roof jack. Professional installation is required for safe alignment, vent connections, fastening, and sealing.
Who installs the AC unit after I purchase it?
ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.
Here’s how it works:
- Hire a licensed HVAC technician in your area
- Use platforms like Angi, Thumbtack, or a local HVAC directory to find reliable professionals
- Confirm your installer is experienced with the system type you’re purchasing
Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
