Clearances

Ensure the minimum clearances shown in Figures 2 through 6 are
maintained. Left and right clearances are determined when facing the
front of the firebox.
Follow these instructions carefully to ensure safe installation. Failure to
follow these requirements may create a fire hazard.
Combustible Side Clearances:
Clearances from the side of the firebox opening to any combustible
material (e.g. side wall, mantel leg, bookshelf, etc.), must comply with
the requirements shown in Figures 2 and 2a.
Example: If the mantel leg, bookshelf or other combustible material
protrudes 5" from the plane of the wall where the firebox is installed,
the combustible material must be a minimum of 6" from the side of the
firebox opening (see Figure 2a).

Ceiling clearance: The ceiling must be at least 40" from the top of the
firebox opening (Figure 2).
Noncombustible material: Noncombustible materials, such as slate and
marble, must be at least 1/2" thick and may be used without restriction
above the firebox opening, to the sides or as a hearth extension, so long
as they do not obstruct vent openings for heat circulating models.
NOTE: To avoid heat-related finish damage, we recommend the use
of high temperature paint (rated 175° F or higher) on the hood and the
underside of the mantel.
