Cutting the hole
Cover fireplace collar opening and cut proper sized chim-
ney hole in chimney. The SK8 pipe allows you to run pipe
through a typical 16" on center joist without cutting joists.
Framing the Ceiling hole
Frame the ceiling chimney hole as shown in Figure 14. It is
good practice to use framing lumber that is the same size
as the ceiling joists; this is a requirement at attic level.

bers:

The inside dimension of the frame must be the same as
the hole size selected from Figure 13 in order to provide
required the 1¹⁄₂" (38 mm) of air space between the out-
side diameter of the chimney and the edges of the framed
ceiling hole.

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 1¹⁄₂" (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. 15)

Fig. 15 Safety strip installation.
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 1¹⁄₂" (38 mm) 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 incorporated on each corner of
the surround. Bend the nailing flanges out, level the box,
then secure it firmly in place by nailing the flanges to the
framing members as shown in Figure 16.
