RSF Woodburning Fireplaces
BENEATH THE HEARTH EXTENSION
If the PEARL3600 is installed on a non-combustible floor,
the cement board and the spark guard specified below are
not required.
Install the spark guard provided (5" x 36" piece of sheet
metal) halfway under the fireplace and halfway under the
hearth extension and centered on the door opening. The
spark guard will extend 2½" beneath the fireplace. This will
make certain that sparks cannot lodge in this area and
start a fire. If necessary, the provided spark guard can be
cut to the minimum width specified in Table 1 (I).
If you are preparing a raised installation, you will need a
custom made spark guard, either a "Z" shaped spark
guard or a right angle spark guard. The Z-shaped spark
guard must be used if the height between the bottom of
the fireplace and the top of the non-combustible flooring of
the hearth extension is less than or equal to 2 ½". The
height of the Z-shaped spark guard must equal the
distance between the floor and the base of the unit and go
under the hearth extension and the fireplace by at least 2½". If the unit is installed higher than 2 ½" from the top of
the flooring, a right-angle spark guard is necessary. The sides of the right-angle spark guard should be at least 2½"
x 2½" and must be covered with non-combustible material. Any custom made spark guard must have the minimum
width specified in Table 1(I), and be installed centered on the door opening.
