The size of the hole in ceiling will vary with the angle at
which the chimney passes through ceiling.
Drive a nail up through ceiling at marked chimney
center point. Go to oor above and see where hole
will be cut. Check to see where existing ceiling joists
and other possible obstructions are located...i.e. wiring,
plumbing etc... If necessary, re-position chimney and/or
replace to avoid obstructions.

Frame the ceiling chimney hole as shown in Figure
10. It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.

Slide replace into position.
Safety strips are used to ensure that any combustible
materials in front of the replace are protected even
though a noncombustible hearth extension is required.
When the nished extended hearth is added, the top
of the nished hearth must be ush with the bottom of
the replace. “Z” shaped metal safety strips have been
supplied with the replace and are required for instal-
lation. The safety strips provided have a 1” offset. For
applications with a greater offset, “Z” shaped strips will
have to be fabricated of metal. Overlap safety strips at
least 1/2” to provide a positive joint. The safety strips
must also extend at least 1¹⁄₂” (38mm) beyond the sides
of the replace. (Fig. 11)
Safety strips are not required over noncombus-
tible oors where all supports at the base of the re-
place are noncombustible.
Two (2) nailing anges are supplied with the replace.
To level the box and secure it rmly in place, remove
the nailing anges from the hearth and install at the
sides of the replace as shown in Figure 12.
