CWC Series Woodburning Fireplace
87D1504
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:
Safety strips are used to ensure that any combustible
materials 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\x"
(38 mm) wide and equal in length to the metal strips
provided with the fireplace.
Safety strips are not required over noncombus-
tible floors where all supports at the base of the fireplace
are noncombustible.
Nailing flanges are integrated on the face of the fire-
place. To level the box and secure it firmly in place, bend
the nailing flanges and install as shown in Figure 15.
