Framing the Ceiling Hole
Frame the ceiling chimney hole as shown in Figure 13. It is
good practice to use framing lumber that is the same size
as the ceiling joists; this is a requirement at attic level.
The following table gives firestop spacer model num-
bers:
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 1
Z\x
" (38 mm)
wide and equal in length to the metal 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.
Nailing flanges are integrated on the face of the fireplace.
To level the box and secure it firmly in place, bend the nail-
ing flanges and install as shown in Figure 15.

Angle of Chimney at Ceiling
The inside dimension of the frame must be the same as
the hole size selected from Figure 13 in order to provide
required air space between the outside diameter of the
chimney and the edges of the framed ceiling hole. (1

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 1
Z\x
" (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.
