Use Non-Combustible materials where indicated for the fireplace installation. Non-combustible materials do not ignite or burn as a result of
using the fireplace. These include metal, brick, ceramic, concrete, slate, glass and plaster. Adhesives must be rated for high temperatures.
Any mechanical fasteners used to install material must also be non-combustible, including wall anchors and tile spacers. Materials that pass
the ASTM E 136 test (Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750C) are considered non-combustible.
