Osburn Fresh Air Kit for legs

A fresh air intake kit supplies dedicated outside combustion air directly to the wood stove through a pipe running from the exterior of the building to the stove's combustion air intake, drawing air from outside rather than from the room air within the installation space. This is recommended in tightly constructed homes where natural air infiltration through the building envelope is insufficient to supply adequate combustion air to the stove during operation. It is required for wood stove installations in mobile or manufactured homes, as these structures are often highly airtight and inadequate combustion air supply can cause harmful levels of carbon monoxide to accumulate. The AC01316 provides the stove-side connection components for this system on legs-mounted stoves.

The fresh air intake connection point on an Osburn wood stove is accessed from the underside of the stove body, and the geometry of the connection approach differs between the legs and pedestal base configurations because the legs and pedestal present the underside of the stove differently. The legs configuration allows access to the stove's underside from the sides and front between the leg members, while the pedestal configuration encloses more of the stove underside behind the pedestal structure. These different geometries require different fresh air intake adapter configurations to reach and connect to the stove's combustion air intake collar, which is why the AC01316 legs kit and AC01336 pedestal kit are separate products that must not be interchanged.

The AC01316 kit provides the stove-side fresh air intake adapter components for the legs-mounted stove. To complete the full fresh air intake installation, the AC02090 5-inch by 4-foot insulated flexible pipe is required to connect the stove-side adapter to the exterior wall penetration point, routing outside air through the building wall to the stove. The AC01349 5-inch fresh air intake register with airtight damper is also available to provide a controllable and airtight wall termination point at the interior wall surface, allowing the fresh air intake opening to be closed when the stove is not in operation to prevent cold air backflow. All three components together — AC01316, AC02090, and AC01349 — provide a complete and controlled fresh air intake system for the legs-mounted stove installation.

Compatibility of the AC01316 with a specific Osburn wood stove model must be confirmed against the fresh air intake installation section of the owner's manual for that appliance. The owner's manual will specify which fresh air intake kit part number is approved for use with the specific stove model in the legs-mounted configuration. As the Osburn range includes multiple stove models with different firebox and base assembly geometries, the fresh air intake kit must be confirmed as the correct part number for the specific model before ordering to ensure the kit's adapter components will connect correctly to that stove's combustion air intake collar from the legs-mounted position.

All fresh air intake installation must comply with local building codes and all applicable standards governing combustion air supply for wood stove installations in the jurisdiction where the appliance is installed. All installation must follow the fresh air intake installation instructions in the owner's manual for the specific Osburn stove model being served. Installation by a qualified installer is recommended to ensure the system is correctly routed, connected, and sealed in compliance with all applicable requirements. The exterior wall penetration for the fresh air intake pipe must be correctly sealed around the pipe to prevent air and moisture infiltration through the wall structure.

Both the AC01316 and AC01421 are 5-inch fresh air intake kits for Osburn wood stoves in the legs-mounted configuration, but they are designed for different stove models and their adapter components are configured for those specific stoves' combustion air intake collar positions. The AC01421 is confirmed as the specific fresh air intake kit for the Osburn 950 wood stove on legs. The AC01316 is the fresh air intake kit for other compatible Osburn legs-mounted stove models. The correct kit must be selected based on the specific stove model being served, as confirmed against that model's owner's manual — the two kits are not interchangeable.
