Installing the Fireplace Insert Enclosure
CUSTOMIZING THE FINISHED APPEARANCE
The facing of the Fireplace Insert Enclosure may be finished to give a variety of different aesthetic
appearances. However, only non-combustible materials may be applied to the face inside the speci-
fied limits for combustible materials. See FIG. 6 on page 8. Outside the combustible limits, the any
surface finish may be used.
For a smooth wall appearance, non-combustible tile backer board may be used as a base for plaster
allowing 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 inside 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 .
•
Combustible trim at the transition to combustible facing material must not protrude into the room
more than ¾” (19mm) from the facing material.
