WARNING
5.4 INSTALLING CEMENT BOARD
If using the supplied cement board that entire surface
must be covered with a non-combustible decorative
fi nish such as brick, marble, granite, etc. The ideal
fi nishing material is dry stack cultured stone.
It is not required to cover the entire surface with a
non-combustible decorative fi nishing material if using
a full single sheet of cement board where required.
However, a minimum of one course of tile is required
to border the sides and top around the door opening.
The larger the tile size, the better.
If only a painted surface is desired, a full single sheet
of Wonder Board cement board must be used.
NOTE: Keep the securing screws for the cement board a minimum of 6” from the side and top of the door
opening. This will allow for any slight movement in the normal operation of the appliance.
Joint Compound where required
Joint compounds such as Durabond 90 and tapes that are resilient to heat and cracking should be used when
taping and mudding seams.
Setting tiles and grouting
We recommend you use tiles with a dry butt joint to be installed using a two-part mortar with an acrylic latex
additive, such as Mapei Kerabond/Kerlastic, to allow for slight movement in the normal operation of the appli-
ance.
If grout is used between the tiles, a polymer-based grout, such as Mapei Ultracolour plus, is recommended.
Primer/Paint
For a painted surface, use a 100% acrylic latex primer and fi nish coat. Light coloured paints may discolour.

A NON-COMBUSTIBLE FINISHING MATERIAL BORDER, SUCH AS BRICK, MARBLE, GRANITE,

THE SURFACE ABOVE THE APPLIANCE GETS VERY HOT. IF PROPER FINISHING MATERIALS ARE
NOT USED, CRACKING CAN OCCUR.
