Factory-Built Fireplace Requirements, cont'd.
The use of the cast iron surround panels may not
be possible in these instances. A custom-built
surround panel system may be used provided it
does not interfere with air circulation through the
convection chamber/ louvers.
• Air flow within and around the factory-built
fireplace shall not be altered by installation of the
insert.
• Alteration of the fireplace in any manner is not
permitted; i.e. firebrick or refractory panels MUST
NOT be removed in order to accommodate the
insert. Exceptions to this are:
a.
External trim pieces, that do not affect the
function of the fireplace, may be removed
providing they can be stored on or within
the fireplace for reassembly if the insert
were to be removed.
b.
The chimney damper may be removed to
install the chimney liner.
• Inserts that project from the factory-built fireplace
must be furnished with appropriate means of
support. The weight of the insert must not com-
promise the means of support for the factory-built
fireplace.
• Fireplace Conversion Notice 220508 must be per-
manently attached to the back of the fireplace. This
metal label is included in the bag containing this
manual.
• Final approval is contingent on the authority hav-
ing local jurisdiction.
