Stand-offs (See Dimensions on page 7) may be removed to fi t the
insert into the fi replace.
When installing the insert into a factory built fi replace, you must not
modify any part that would alter the integrity in any way. Bolted or
screwed together pieces (smoke shelf/defl ectors) may be removed,
but must be able to be re-installed if the insert was removed.
External trim pieces, which do not affect the operation of the fi re-
place, may be removed provided they are available to be re-installed
in event the insert is removed.
A warning label must be attached to the back wall of the fi replace
stating that "This fi replace has been altered to accommodate a fi re-
place insert and must be re-inspected by a qualifi ed person prior to
re-use as a factory built fi replace".
A non-combustible hearth must cover the fl ooring underneath, as well
as extend a minimum of six in front and to both sides of the heater.
Install fl oor protection if necessary.
