About this model
Overview
The Inspire 2000-I pairs a 2.4 cubic foot non-catalytic firebox with a wide 20 1/4 by 9 1/2 inch letterbox window, which gives it a different look from the near-square Matrix models. Three faceplates are offered: a cuttable 32 by 50 inch plate and narrow U-shape or four-sided plates for tighter faces.
It is EPA 2020 cordwood certified at 2.3 g/hr published emissions with 72% HHV efficiency, and a 176 CFM heat-activated blower is included. The deepest requirement in the range is its minimum opening depth of 20 3/4 inches, which is the figure that most often rules it in or out.
Is this right for your home?
A masonry fireplace with enough depth for the appliance, where a wide window and a choice of face treatments matter.
Check before ordering
- The masonry opening against the minimum of 24 5/8" H x 29" W x 20 3/4" D, the depth being the common barrier.
- Which faceplate suits the face: cuttable 32" x 50", narrow U-shape 30" x 25 1/8" or narrow four-sided 30" x 26 7/8".
- The condition of the chimney and the liner run it needs.
Worth knowing
- The published heating range of 500 to 2,100 sq ft depends on insulation, layout and climate.
- The 8-hour figure is the maximum burn time, not the period of useful heat.

Figures published by the manufacturer. Where a value applies to a specific model or configuration, it is noted in the row.
Installation
Depth decides this one. At 20 3/4 inches the minimum opening depth is the deepest in the range, so the measurement is taken before anything else is discussed. The insert is then installed in a code-compliant masonry fireplace with a continuous full-height stainless steel liner.
Brown Chimney can measure the opening, inspect the chimney and confirm which faceplate suits the face before anything is ordered.
Service availability depends on your location.
What to check before installation
What an assessment of this model would cover:
- Measured depth of the masonry opening against the 20 3/4 inch minimum, plus height and width.
- Chimney condition and the liner run required for its full height.
- Which faceplate covers the existing face cleanly.

Frequently asked questions
Why might this model not fit?
Usually depth. The manual asks for at least 20 3/4 inches of depth in the masonry opening, which is more than the other inserts in this selection.
What faceplates are offered?
A cuttable 32 by 50 inch plate for larger faces, and narrow U-shape or four-sided plates around 30 inches wide for tighter openings.
How big is the window?
20 1/4 by 9 1/2 inches of ceramic glass, a wide letterbox shape rather than the near-square window on the Matrix models.
