Raised Installations
The fireplace may be raised by building a platform of sufficient strength to 
support the fireplace and pipe. When building a raised hearth extension, 
please see the note below regarding height of the fireplace in relation to 
the thickness of the hearth extension material.
Hearth Extension Considerations
It is IMPORTANT to note that there is a 1” space between the base of the 
fireplace and the bottom of  the fireplace face. See  Page 13 for hearth 
extension requirements. This space will allow a 7/8” (22 mm) thick hearth 
extension (including backer board if desired). Should a hearth extension 
thicker than 7/8” (22 mm) be desired,  the height of the fireplace must 
be raised the thickness of that hearth extension less the 7/8”  (22 mm). 
For example, if a  2-7/8” (73 mm) thick  cultured stone is  to be placed 
on the floor to serve as the hearth extension, then the fireplace must be 
raised 2” (possibly using 1/2” (13  mm) plywood over 2 x 4’s laid  flat) 
to accommodate the 2-7/8” (73 mm) stone. It is important to note that 
if the fireplace is raised,  then it is necessary  to raise the height  of the 
header above the stand-offs an equal amount.
