Osburn 1700 Wood Insert | OB01705

Osburn 1700 Wood Insert | Model OB01705

The Osburn 1700-I OB01705 offers a practical path to converting a modest masonry fireplace into a more effective supplemental heater. Sized below the 2000-series insert, it retains a traditional cast iron door and a welcoming glass view suited to medium-size living areas and smaller hearth installations.

High-density firebrick, a C-Cast baffle and a blower help support durable everyday operation and move warmed air back into the room. Buyers can choose among compatible faceplates, trims and door-overlay finishes to create a clean transition between the insert and existing masonry.

Why the Osburn 1700-I Suits Smaller Hearths

The 1700-I is a logical step up from an open masonry fireplace when the goal is to heat an everyday living area without buying a large insert. Its 1.86-cubic-foot firebox is smaller than the Osburn 2000-I's 2.4-cubic-foot unit, so it is worth considering when fireplace dimensions or heat demand rule out a larger model. A cast iron door, ceramic glass window and included blower retain the familiar appearance of a wood fire while directing more warmth into the occupied room.

Take the time to measure the masonry fireplace opening and the depth available for the insert body. Check the hearth extension, faceplate coverage and 6-inch liner path in the manual before assuming the unit will work. Door overlay and trim options can help match the existing room, but they do not change the firebox's certified opening or clearance requirements. This insert is designed for approved masonry fireplaces and must not be treated as a wood stove for a combustible enclosure.

Manufacturer figures are reference values, not guaranteed heating results. Maximum BTU output, tested output rates and burn-time estimates use different conditions; real performance depends on fuel quality, chimney draft, climate, home heat loss and operating settings. Confirm all dimensions and listed installation clearances in the current manual before ordering.

Installation and Compatibility

Install the 1700-I only in a suitable existing masonry fireplace with a listed 6-inch liner. Check opening depth, height, width and hearth protection rather than relying on appearance alone to determine fit.

Important: Wood-burning inserts must be installed only in a compatible existing masonry fireplace, in accordance with the manufacturer's listing and installation instructions.
