Calcium silicate board is a high - grade material
with cement, quartz, natural and selected
minerals as the main raw materials. It is widely
used for partitions and ceilings in buildings.
It is fi re proof and earthquake proof.
If fi nishing the wall above the unit with materials
such as tile, brick, marble, etc. non-combustible
board available from the building supply store
can be used.
Note: Calcium Silicate is 1/2' thick
Caution:
The non-combustible board supplied with this unit can
be damaged if dropped or struck. Handle with care.
1) Using drywall screws - secure non combustible material
around unit, framing and top nailing strip every 6 inches.
Important Note: To avoid cracking the board - pre-drill holes prior to
securing to unit/ framing.
2) Wipe any debris/dust from the non combustible
material and drywall.
3) Prior to taping and mudding it is highly recommended
to prime the facing using a quality primer. This will
ensure proper adhesion of both the tape and mud.
The supplied board is very porous.
4) Tape the seams using a mesh type tape.
5) Mud seams as normal. We recommend using a
product called Durabond high strength compound - for the fi rst coat.
This product can be found at any hardware store.
Mud must be cured as per manufacturer's recommendations.
6) Prime wall for a second time for proper adhesion of paint
7) Paint walls using a high quality paint which will withstand
the high temperatures being emitted from this appliance.
