Hearth Protection Requirements
The floor area in front of fireplace insert must be
protected from live sparks and radiant heat.
• Materials:
Hearth protection must be non com-
bustible insulating board such as 1/2” millboard, or
the equivalent mortared masonry material. Alter-
nate protection must be composed of materials as
specified by NFPA
211.
• Protected Area:
U.S: 16” Deep x 37” Wide
CAN: 20” Deep x 37” Wide
See exception for 18” depth below.
U.S. : Front -
The protection must extend at least 16 inches
forward from the fireplace insert door opening as
in fig. 4. (14 7/8” from Surround facing).
Canada: Front -
The protection must extend at least 20 in. forward
from the fireplace insert door opening, (18 7/8”
from Surround facing).
Front protection may be reduced to 18” under the
following conditions:
a) it is composed of noncombustible material
having an R value of .5 or higher such as 1/2” thick
millboard. See Appendix A on page 23 for exam-
ples.
b) it is raised a minimum of 2 1/2” and constructed
on noncombustible materials in a code-approved
masonry fireplace. See fig. 5.
U.S. & Canada: Sides -

• The convection chamber/louvers of the zero-
clearance fireplace MUST NOT be blocked off. 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
compromise the means of support for the factory-
built fireplace.
• Fireplace Conversion Notice 220508 must be
permanently 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 having
local jurisdiction.
