Hearth Extension - Majestic MARQ36IN-B Installation Manual

D. Hearth Extension
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 3.8 and Figure 3.9.
• The base of the fireplace may sit on a combustible
surface. See Figure 3.9. The area in front of the
appliance 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 3.9 and Figure 3.10.
• If a hearth greater than one inch in thickness is de-
sired, the appliance must be raised by the equivalent
height to ensure that the hearth extension does not
interfere with the installation of the glass assembly
required for fireplace operation. See Figure 3.9.
