1.0 PRE-INSTALLATION REQUIREMENTS
1.1 Masonry fireplace requirements
The masonry fireplace must meet the minimum code requirements, or NFPA 211 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:
Examine the masonry fireplace and chimney 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 prior to
installation.
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. LINER:
The chimney must have an acceptable 6" (152 mm) stainless steel chimney liner installed.
NOTE: The 2400 Insert is not approved for use with a positive flue connector into a masonry
flue.
4. 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 mantel area. Your local inspector should have information on
whether older fireplaces are of adequate construction.
5. OPENING SIZE:
Refer to “Minimum masonry opening” (Section 2.7) for suitable size fireplace openings.
NOTE:
A METAL TAG IS PROVIDED AND IS TO BE FASTENED TO THE BACK WALL OF THE
FIREPLACE, IF THE FIREPLACE HAS BEEN MODIFIED TO ACCOMMODATE THE
INSERT.
