With its 2.4 cubic foot firebox, the Osburn 2000 insert is 2020 EPA compliant and offers an alternative to the people who love its freestanding counterpart. The two models share the same high quality combustion properties and many of the same features. The Osburn 2000 fireplace insert comes with a standard high-power, heat-activated 144CFM fan strategically positioned to redistribute the heat from the firebox into the room. The 2000 insert is designed to receive an optional faceplate that can cover a masonry hearth up to 32 inches (81 cm) high and 50 inches (127 cm) wide. The door overlay is available in black or brushed nickel plated finishes. The faceplate trims are available in black or nickel.

Door Overlay & Faceplate Option Details

Door Overlay

The Door Overlay is required to complete the installation. The Door Overlay is available in either black or brushed nickel finish. The options for the Door Overlay allow you to tailor the look of the fireplace insert to your liking. The Black Door Overlay gives the fireplace insert more of a traditional style, while the Brushed Nickel Door Overlay gives the stove a more sleek and modern look. The Door Overlay easily installs to the stove with the included bolts.


The Faceplate is the component that flashes around the fireplace insert and covers the fireplace. The Faceplate is available in two sizes: 29" x 44" and 32" x 50". The size you choose should be based on the opening of your existing fireplace. Choose the 29" x 44" Faceplate size if the opening of your fireplace is less than 29" x 44". If your fireplace opening is greater than 29" x 44", you will want to select the 32" x 50" Faceplate size.

Cuttable Faceplate (18 gauge) 32" x 50"

If you have a nice arched fireplace and would like the Faceplate to conform to the shape to show the nice field stone keystone, then the Cuttable Faceplate is for you. Simply trace the shape onto the Faceplate and use metal cutting snips to cut the Faceplate to size and shape. Making a template is generally the easiest way to transfer the shape. The Cuttable Faceplate does not require a Faceplate Trim Kit.

Faceplate Trim

The Faceplate Trim is required for finishing the installation of the Regular or Large Faceplate and completes the wood insert installation. The Faceplate Trim is available in either black or brushed nickel. Choose the size for the Faceplate Trim based on the size of the Faceplate you chose. You have the option to match the Faceplate Trim to the same color as the door overlay. Or, you can mismatch to add dimension to the style of the fireplace insert. Note: The Faceplate Trim is not needed if you chose the Cuttable Faceplate.

Optional Accessory Details

5" Fresh Air Intake Kit Oval

The 5" Fresh Air Oval Kit is required if you plan on connecting a fresh air intake pipe. The oval adapter kit comes with the oval adapter, 2 clamps and the fresh air intake register hood. The oval adapter is intended for 5" fresh air intake pipe. You will have to manually ovalize the flexible intake pipe to make the connection to the adapter. The oval adapter can be positioned on either side of the stove.

Rigid Fire Screen

The Rigid Fire Screen allows you to burn wood in the fireplace insert with the door open just like an old-time fireplace. Hear the crackle of the wood, watch the flames dance around in the firebox and relax around the wood insert on a cold winter's night. The Rigid Fire Screen is easy to install and easy to remove when you are ready to load more wood. The fireplace insert should not be burning with the door open without the firescreen.

Heat Shield For Surround / Shelf - 7 3/16" x 26"

The optional Heat Shield for Surround Shelf is the easiest way to lower a combustible mantel or shelf down closer to the fireplace insert. With the Heat Shield install, you can lower your combustible mantel to 21" above the stove. The combustible mantel must be wider than 12". The standard clearance for a combustible mantel is 27" above the stove. The Heat Shield will give you more freedom and flexibility when planning the layout of the room.

5" Fresh Air Intake Register with Airtight Damper

5" Fresh Air Intake Register with Airtight Damper opens and closes the fresh air supply to a wood stove insert. It's simple mechanism makes it possible to close the damper tightly when the wood stove insert is not in use. This will ensure the wood stove insert is not being cooled while the stove is not in use.
