Pre-Installation Requirements
FIREPLACE CONDITION AND ZERO CLEARANCE REQUIREMENTS
A masonry replace must meet minimum code requirements, National Fire Protection Association, (NFPA) 211, or
the equivalent for a safe installation. Contact a professional, licensed installer, your local building inspector or the
local re authority for the requirements in your area. Your insurance company should be able to recommend a
qualied inspector.
Inspections should include the following:
1. Condition of the replace and chimney. A masonry replace and chimney MUST be inspected prior to
installation of this appliance. They must be free from cracks, loose mortar, creosote deposits, blockage or
other evidence of deterioration. If found, these items MUST be repaired prior to installation. DO NOT REMOVE
BRICKS or MORTAR from existing replace when installing this unit.
2. Chimney Size. Minimum chimney size is 6” (153 mm) diameter. Maintain a 15 ft. minimum overall chimney
height measured from the top of appliance to the top of the chimney. Chimneys must extend at least 3 ft.
above the roof and at least 2 ft. above the highest point within 10 ft. of the chimney top. See the Chimney
Connections section of this manual.
3. Zero Clearance or Metal Heatform Fireplaces. These replaces and chimneys must meet the minimum code
specications as noted above. Factory built zero clearance replaces must be listed and suitable for solid fuel
use. Chimneys must be at least 7 inch diameter to accommodate a required, continuous, stainless steel liner
from the appliance’s ue collar to the top termination of the chimney. Only detachable parts that can be
easily replaced (i.e. damper parts, screens, doors and side, and back refractory panels) are to be removed.
These parts must be stored and readily available for replacement if the appliance is ever removed. The
removal of any parts that render the replace unusable for burning solid fuel requires a permanent label to
be afxed by the installer that states the replace is unsuitable for burning solid fuel unless the missing parts
are replaced and the replace is restored to its original, certied condition.
4. Chimney Caps. Mesh type chimney caps and spark arrestors must be able to be removed for regular
inspection and cleaning. Otherwise the mesh should be removed to prevent possible plugging. Check your
local re and building codes.
5. Chimney Liner. The chimney must be suitable for burning solid fuel. Install a continuous stainless steel liner from
the ue collar of the appliance to the top of the chimney. Liner must be UL Listed to UL1777.
6. Combustible Material Clearances. The replace and chimney
must be inspected to make sure there is adequate clearance
to combustible materials. This includes the top, side, front, and
back as well as concealed combustibles in the chimney and
mantle areas. Your local building inspector or re authority
should have information on whether older replace meet
current codes and are suitable for use. See also gure 1 and
gure 2.
