PART B - INSTALLATION
7. 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 the local building inspector for
requirements in the area. An inspection of the fireplace should include the following:
Condition of the fireplace and chimney
• The masonry fireplace and chimney should be inspected prior to installation, to confirm
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 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 what is required by the building code.
Installation into an existing factory-built zero-clearance fireplace
• It is possible to install a wood insert into an existing factory-built zero-clearance fireplace.
However, there currently exists no standard specific to that type of installation. The factory-
built zero clearance fireplace must be listed; that is, safety certified by an accredited
certification agency. It must be suitable for use with solid fuel and nothing in the owner's
manual must specifically prohibit the installation of a fireplace insert. When in doubt, check
with the fireplace manufacturer.
• The installation of the zero-clearance fireplace MUST be thoroughly inspected by a qualified
person to ensure that it still meets the manufacturer's specifications. The chimney must be at
least 1" (25 mm) larger in diameter than the stainless steel liner that will run from the insert
flue collar to the top of the chimney termination.
• Never remove parts intended to insulate the zero-clearance fireplace from combustible material.
Only readily detachable parts that are easily replaced, such as damper parts, screens, and
doors, are to be removed from the fireplace. These parts should be stored and available for
reinstallation if the insert is ever removed.
• Removal of any parts, which render the fireplace unfit for use with solid fuel, requires the
fireplace to be permanently labelled by the installer as being no longer suitable for solid
fuel, until the removed parts are replaced and the fireplace is restored to its original certified
condition. Also, any air vents, grilles, or louvers that allow air circulation around the fireplace
must not be removed or blocked.
Chimney caps
• Mesh type chimney caps must have provision for regular cleaning, or the mesh should be
removed to eliminate the potential of plugging.
