HEARTH REQUIREMENTS
When using the Insert 60 in the Fireplace Insert Enclo-
sure, the hearth protection requirements are different than
when installing the Insert 60 in an existing masonry fire-
place. The enclosure has been designed to elevate the
Insert 60 to the minimum distance above the combustible
floor where no thermal floor protection is required. How-
ever, unless the Insert 60 Fireplace Insert Enclosure will
be installed on a completely non-combustible surface
such as unpainted concrete over earth, spark and ember
floor protection must be provided in front of the insert and
enclosure. This will protect the combustible floor in front
of the load door from spilled coals or embers.
The floor protector can be made from any completely
non-combustible material such as galvanized steel or
non-combustible tile backer board. These materials may
be covered with decorative non-combustible materials
such as ceramic tile. Other non-combustible materials
may be used if there are no gaps or joints between pieces
that would allow coals or embers to reach the combustible
floor underneath. Floor protectors meeting the require-
ments of UL-1618 Type 1 are acceptable.
The floor protector must extend at least 8” (203mm) from
the sides of the firebox opening making the minimum total
width of the floor protector 34 ½ “ (875mm). In addition,
the floor protector must extend a minimum of
16” (406mm) in front of the door opening in the United
States and 18” (457mm) in Canada. See Fig. 8.
In addition, a 3” X 34 ½” (76mm X 875 mm) sheet metal
spark protector strip must be laid under the junction be-
tween the front of the enclosure and the floor protector to
prevent coals or embers from reaching the combustible
floor. See Fig. 7 on page 5.
COMBUSTIBLE MANTEL
A combustible mantel and any associated trim may be
mounted to the wall above the Insert 60. The mantel (or
trim) must be a minimum of 24 1/4” (616mm) above the
top flange on the Insert 60. See Fig. 9. The mantel may
not be deeper than 12” (305mm).
CUSTOMIZING THE FINISHED
APPEARANCE
The facing of the Fireplace Insert Enclosure may be fin-
ished to give a variety of different aesthetic appearances.
However, only non-combustible materials may be applied
to the face inside the specified limits for combustible ma-
terials. See Fig 6 on page 5. Outside the combustible
limits, any surface finish may be used.

backer board may be used as a base for plaster al-
lowing a seamless transition beyond the combustible
limits to traditional wallboard.
For tile, veneer brick or stone, the finish material may
be applied over non-combustible tile backer board.
The requirements for the facing material applied in-
side the combustible limits are:
The material must be non-combustible.
The total thickness, including non-combustible
backer board and adhesive should not exceed
13/16” (20mm).
Facing materials should not encroach into the
front opening in the enclosure in order to allow
proper insertion of the Insert 60.
Combustible trim at the transition to combustible
facing material must not protrude into the room
more than ¾” (19mm) from the facing material.
