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

A hearth extension in front of the fireplace is not required; however, to
enhance the appearance of the Ravelle™ 42 gas fireplace, one is recom-
mended . Note: There is a 1" (25 mm) space between the base of the
fireplace and the bottom of the decorative fireplace face. 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" (51 mm) (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 . If you wish to install your fireplace without a hearth
extension you must remember to set your finished flooring height 1" (25
mm) higher than the bottom base of the fireplace or install the fireplace
1" (25mm) lower than the finished flooring materials for that room . This
will assure that no gap will exist between the room's flooring and your
new fireplace decorative face after it is installed .
