PART B - INSTALLATION
6 Pre-Installation Masonry Fireplace Requirements
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 CHIMNEY
The masonry fireplace and chimney 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 chimney 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 insert’s chimney liner, provided
that their removal will not weaken the structure of the fireplace and chimney, and will not
reduce protection for combustible materials to less than that required by the building code.
2. CHIMNEY CAPS
Mesh type chimney 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 chimney and mantle area. Your local inspector should have
information on whether older fireplaces are of adequate construction.
4. OPENING SIZE:
Refer to the
MINIMUM MASONRY OPENING

Section 8.5
