Notice for Finishing Materials
The wall above the fireplace will become hot. Install the
non-combustible board supplied with the fireplace before
adding paint, tile or stone. Attach tile or other non-combustible
products to the fireplace face and to the non-combustible
area
(Figures 29 and 30)
using adhesives designed for
high-temperature applications. Follow the manufacturer's
instructions for application and curing times. Heat from the
fireplace may cause incorrectly installed materials to fail. If you
are painting above the fireplace, use a coating designed for
high temperature environments and follow the manufacturer's
instructions for surface preparation, application and curing.
Heat from the fireplace may cause incorrectly applied coatings
to fail or discolor.
Non-combustible Board Requirements
1. Do not attach non-combustible board to the fireplace. Attach
non-combustible board only to side studs and header board.
2. Predrill holes into non-combustible board. Counterlink holes
are recommended.
3. Use only high-temperature adhesive and high-temperature
paints with the non-combustible board.
4. Do not over-tighten screws going through non-combustible
board.
