5.2 Clearance Requirements
The following clearances and hearth specifications are
the minimum requirements for installing this appliance
into a solid fuel-burning fireplace. See figs. 5.3-5.5.
A combustible surface is anything that can burn (i.e.
sheet rock, wallpaper, wood, fabrics etc.). These surfaces
are not limited to those that are visible and also include
materials that are behind non-combustibles.
If you are not sure of the combustible nature of a
material, consult your local fire officials. Remember, “Fire
Resistant” materials are considered combustible; they
are difficult to ignite, but will burn. Also, “fire-rated”
sheet rock is considered combustible.
Always maintain the proper clearances to allow for
the flow of ventilation air around the insert.
