RSF Woodburning Fireplaces
HEARTH EXTENSION
The area immediately in front of the fireplace must be protected by a non-combustible material such as brick, tile,
stone, or slate. Refer to Table 1 (G-H) for the depth and width that the hearth protection should extend beyond the
front and both sides of the door opening (see Figure 1). There is no minimum thickness required for the hearth
extension.
BENEATH HEARTH EXTENSION
If the CHAMELEON2 is installed on a non-combustible floor, NONE of the cement board and the spark guard
specified below is 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 (see Figure 13).
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.
NOTE
: Custom-made spark guards are not supplied.
In the USA only:
A ½" cement board, such as Durock© or an equivalent cement board, MUST be installed beneath the
hearth extension. The cement board must have the same minimum dimensions as the hearth extension
(see Table 1 (G-H)). If the fireplace is raised by at least 4", the cement board is NOT required.
The spark guard must be installed under any of the layers of the hearth extension.
MANTEL
Refer to Table 1 (J) for the maximum depth of the mantel and its installation height. Wood or other combustible
mantels must be placed as specified in Table 1 (K) and illustrated in Figure 1.
