Positioning, Safety Strips,
Securing the Fireplace
Slide fireplace into position.
Lift the fireplace front slightly and slide the metal safety
strips under front bottom edge about 1Z⁄₂" (38 mm), allowing
the remainder to extend in front of firebox. Overlap strips
at least 1/2" (13 mm) to provide a positive joint. (Flat safety
strips are packed with fireplace.) (Fig. 14)
Safety strips are used to ensure that any combustible ma-
terials in front of the fireplace are protected even though
a noncombustible hearth extension is required.
If fireplace is to be elevated above the floor, a "Z" shaped
metal safety strip must be fabricated and used to protect
combustible surfaces in front of the fireplace. This "Z"
shaped safety strip is not provided but must be fabricated
of metal with each horizontal leg at least 1Z⁄₂" (38mm) wide
and equal in length to the metals strips provided with the
fireplace.
Note: Safety strips are not required over noncombustible
floors where all supports at the base of the fireplace are
noncombustible.
Four (4) nailing flanges are supplied with the fireplace
(found on the fireplace hearth). To level the box and se-
cure it firmly in place, remove the nailing flanges from the
hearth and install at the sides of the fireplace as shown
in Figure 15.
