Before You start
Before installing, read these instructions and the Vent Kit
Instructions to ensure proper installation. Consult local Building
Codes before beginning the Installation.
NOTICE: Cutting the sheet metal parts of an existing fireplace to
install the fireplace insert is prohibited unless mentioned below.
1.
The fireplace and fireplace chimney must be cleaned and
inspected to insure it is in good working order. The venting
for the fireplace insert must run through the chimney for the
fireplace or masonry chimney and meet criteria on NFPA211.
Do not handle barrier screen or door assembly with your
bare hands! (Always Wear Gloves)
2.
Remove the barrier screen, glass door and log package from
the fireplace insert. Check for damage to the fireplace insert
or its components.
3.
Plan out the gas, venting and electrical route. Start with the
gas line, followed by the chimney preparation and electrical
supply requirements.
4.
Make sure that all chimney cleanouts fit properly so air
cannot leak into the chimney.
5.
Remove or lock the fireplace flue damper in the fully open
position.
6.
The minimum fireplace opening requirements are shown in
page 11 of this installation manual. The firebrick (refractory),
glass doors, screen rails, screen mesh and log grates can
be removed from a factory built fireplace to increase the
opening size.

The fireplace insert does not require any additional hearth
extension, however, the original hearth materials installed
with the fireplace must be retained. If the original materials
have been damaged or removed, a new one must be
installed. Hearth materials must consist of a non-combustible
material such as brick, tile, slate or marble extending the
width of the fireplace and out a minimum of 16 inches in
front. Wood flooring, vinyl, or carpet are not allowed directly
in front of the fireplace insert.
NOTICE: The original fireplace cannot be returned to
solid fuel use without returning the hearth extension to the
specification required for a solid fuel fireplace.
8.
The metal floor of the solid fuel firebox may be removed to
install the insert. If the firebox floor is removed, the insert
must be raised off the floor of the fireplace at least 1/4 inch
to protect the combustible surface under the original
fireplace. Clearance to combustible material under the insert
is 1/4-inch. Combustible material must not be placed inside
the original area. The side walls and top structure of the
firebox may not be altered with the exception of removable
baffles and dampers. The original fireplace cannot be
returned to solid fuel in this condition.
