Key Features

• Designed for Osburn Matrix-I Wood Fireplace Insert (OB02028)

• Ensures flush alignment with the fireplace finish
• Factory-engineered OEM accessory
• Required when faceplate projection exceeds 0"

Important Installation Requirement

⚠️ Backing Plate Kit Required (Sold Separately)

In order to install the optional projection kit AC01323, one of the following faceplate backing plate kits must be purchased separately to secure the projection kit:

• AC01322 (29" x 44")
• AC01332 (29" x 50")

The projection kit attaches directly to the faceplate backing plate and cannot be installed independently.

Product Features

Corrects Insert Faceplate Projection

If the cast iron faceplate projects beyond the fireplace finish (greater than 0"), the AC01323 projection kit is required before final faceplate installation.

This ensures:

• Proper visual alignment
• Secure mounting
• Clean, professional finish

Dual Projection Options – 2" or 4"

The kit allows you to configure:

• 2-inch projection (by separating sections at micro joints)
• 4-inch projection (full assembly)

This flexibility allows installers to adjust for varying hearth depths and masonry fireplace finishes.

Precision-Engineered Mounting Points

The convection air jacket of the Matrix-I insert includes predrilled holes that correspond to:

1. 0" projection
2. 2" projection
3. 4" projection

⚠️ The hole locations must not be altered to prevent overheating.

OEM Steel Construction for Structural Support

Constructed from durable steel components (G, H, J sections), the projection kit:

• Secures the backing plate using 6 screws
• Provides rigid support for extended faceplate alignment
• Maintains proper airflow clearance

Required for Many Masonry Fireplace Installations

Common reasons homeowners need a projection kit:

• The fireplace surround sits proud of the insert cavity
• Stone, brick, or tile extends past the firebox opening
• Renovation changed fireplace finish depth

If your Matrix-I faceplate does not sit flush, this kit is the correct solution.
