Extended Furnace Venting for Deep Manufactured-Home Roof Cavities
A long adjustable roof jack provides proper combustion-air intake and exhaust termination.
The Intertherm 903666A is a long adjustable roof jack for compatible manufactured-home furnaces installed beneath a nominal 4/12 sloped roof. Its 51-to-95-inch adjustment range is intended for deeper ceiling and roof assemblies that cannot be served by a shorter roof jack.
Intertherm, formerly marketed under the Revolv name, designed this assembly to bring outdoor combustion air to the furnace and safely carry flue gases through the roof. Its telescoping construction helps the installer match the measured roof-cavity height, while the flashing and upper termination components support a properly sealed installation. This model is listed for compatible R, MG1, and M5S furnace applications.
- 51-to-95-inch adjustment range: Reaches through deep manufactured-home roof cavities.
- Nominal 4/12 roof pitch: Designed around an appropriate sloped-roof installation.
- Combustion-air intake: Supplies the compatible furnace with air from outdoors.
- Flue-gas exhaust: Directs furnace combustion products safely above the roof.
- Telescoping assembly: Allows field adjustment within the approved length range.
- Integrated flashing: Supports a properly positioned and weather-sealed roof opening.
- Manufactured-home application: Designed for compatible specialized furnace installations.
- R/MG1/M5S compatibility: Intended for approved furnace models within these equipment families.
Select the 903666A when a compatible R, MG1, or M5S furnace requires a 51-to-95-inch roof jack. Do not substitute it for the similarly sized 903676A without confirming the furnace application. Professional measurement and installation are required.
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.
