Osburn Matrix Inbuilt Installation and Operation Manual
PART B – INSTALLATION
6 PRE‐INSTALLATION REQUIREMENTS
6.1 MASONRY FIREPLACE
The masonry fireplace must meet the minimum requirements found in the building code enforced
locally, or the equivalent for a safe installation. Contact your local Building Inspector for
requirements in your area. An inspection of the fireplace should include the following:
1. CONDITION OF THE FIREPLACE AND FLUE SYSTEM:
The masonry fireplace and flue system should be inspected prior to installation, to determine
that they are free from cracks, loose mortar, creosote deposits, blockage, or other signs of
deterioration. If evidence of deterioration is noted, the fireplace or flue system should be
upgraded and/or cleaned prior to installation.
Masonry or steel, including the damper plate, may be removed from the smoke shelf and
adjacent damper frame if necessary to accommodate the wood inbuilt's flue liner, provided
that their removal will not weaken the structure of the fireplace and flue system, and will not
reduce protection for combustible materials to less than that required by the building code.
2. FLUE SYSTEM CAPS:
Mesh type flue system caps must have provision for regular cleaning, or the mesh should be
removed to eliminate the potential of plugging.
3. ADJACENT COMBUSTIBLES:
The fireplace should be inspected to make sure that there is adequate clearance to
combustibles, both exposed combustibles to the top, side, and front as well as concealed
combustibles, in the flue system and mantle area. Your local inspector should have
information on whether older fireplaces are of adequate construction.
4. OPENING SIZE:
Refer to "MINIMUM MASONRY OPENING" (Section 8.5) for suitable size fireplace openings.
6.2 ZERO‐CLEARANCE KIT
5. INSTALLATION INTO AN EXISTING FACTORY‐BUILT ZERO‐CLEARANCE FIREPLACE:
A 'built‐in' appliance is designed to be in contact with or built into a heat sensitive structure
within a building. These types of appliances must be tested in a laboratory in accordance with
AS/NZS 2918 to ensure their compliance with safety requirements. There is no such thing as a
'standard' (untested) built‐in appliance. As each model or appliance may have markedly
different installation clearances and instructions, it is extremely important to follow the
manufacturer's installation instructions, which are based on the laboratory tests results. The
Matrix inbuilt can only be installed with the Osburn Matrix zero‐clearance kit (sold
separately). See installation instructions provided with the kit.
