WARNING! Risk of Fire! Non-combustible hearth exten- sion may be required when appliance is installed on com- bustible surface.

• Hearth extension must be non-combustible and serves to protect combustible floors in front of appli- ance. See Figure 5.11.

• The base of the fireplace may sit on a combustible sur- face. See Figure 5.11. The area in front of the appli- ance must be protected by a non-combustible hearth extension, unless the appliance is raised a minimum of three inches above the combustible floor or hearth. See Figure 5.11 and Figure 5.12.

Figure 5.10 Non-Combustible Hearth Extension Dimensions

NOTICE: DO NOT install a hearth that is greater than one inch thick. Hearth will interfere with installation of glass assembly. Total hearth height must not exceed one inch from bottom of appliance when appliance is installed directly on floor (including mortar, backer material, etc.)

If a hearth greater than one inch in thickness is desired, the appliance must be raised by the equivalent height to ensure that the hearth does not interfere with the installation of the glass assembly required for fireplace operation. See Figure 5.11.
