FOCUS 250 Owner's Manual

RSF Woodburning Fireplaces
The area in front the fireplace legs, below the bottom louver, MUST also be covered with NON-COMBUSTIBLE
materials (see Figure 5). The L-shape spark guard provided will cover the front of the legs and offer support for the
facing materials. See below for the installation instruction of the spark guard.
The front surface of the top standoff is part of the fireplace facing and MUST also be covered with NON-
COMBUSTIBLE materials (see Figure 5).
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 THE HEARTH EXTENSION
If the FOCUS 250 is installed on a non-combustible floor, the spark guard is needed to cover the legs of the fireplace.
The L-shape spark guard provided will not only protect against sparks and small embers that may fall at the very
front of the fireplace but it will also close the front of the legs and support the facing materials.
If you have decided to remove the 1"x4" below the fireplace legs, you will need to cut off ¾" from the tall side of the
L-shape spark guard.
Install the L-shape spark guard provided (1" bend x 6
3
/
8
" x 32½" piece of sheet metal) in front of the legs of the
fireplace. It should be aligned with the fireplace. Use a couple of wood screws to attach it to the floor and use the
two self-tapping screws provided to attach it to the base of the fireplace. If you plan on covering the facing of the
fireplace with glued ceramic tiles, place the screws so that they will be located behind the grout joint.
If you are preparing a raised installation, more than ½", you will need a custom made spark guard:
•
You can add a custom plate (thickness: 0.060" minimum, width: 32½", height: raised 1½" for overlap)
that will be attached to the base of the fireplace as an extension to the provided L-shape spark guard. Install
the provided L-shape spark guard as described above, attaching it to the thick plate instead of the base of the
fireplace.
•
Or you can make a custom L-shape spark guard (thickness: 0.024", width: 32½", height: raised 6
3
/
8
"
+ 1" for the bend) and install it as above.
NOTE
: Custom-made spark guards are site built.
MANTEL
Masonry and other non-combustible mantels (shelf and posts) can be placed anywhere on or around the fireplace
facing, without blocking any of the bottom and top louvers. If the non-combustible mantel is located between the
top of the fireplace facing and the specified height for a combustible mantel, then the wall portion between the top
of the fireplace facing and the mantel must be covered in non-combustible material. If the non-combustible mantel
is located at the same height allowed for a combustible mantel, or higher, then no special wall covering is required
below the mantel.
For combustible mantels shelves, please see Table 1 (J-K) for the maximum depth of the mantel shelf and their
clearance requirements. See Figure 1 for an example.
Vertical mantel posts on the sides of the fireplace opening must be non-combustible. Combustible mantel posts are
not permitted unless they meet the clearance required to a perpendicular sidewall (see Table 1 (B)).
