11.3 installing non-combustible board
WARNING
!
•
The surface above the appliance gets very hot. If proper fi nishing materials are not used, cracking can occur.
•
See fastener placement restrictions. Longer screws may damage gas line and/or internal components.
1. Align the top non-combustible panel against the appliance and secure in place with the drywall screws.
2. Align the side non-combustible panels against the appliance and secure in place with the drywall screws.
No fasteners permitted
No fasteners permitted with greater than 3/4"
penetration into appliance.
note:
The 15 5/8" (39.7cm) above and the 7" (178mm) on either side of the appliance opening must not be fi nished
with any combustible materials.
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
appliance.
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.
note:
We recommend using high temperature adhesive and clamping to adhere drywall to lower access panel.
Secure with fasteners no longer than 3/4", see "fastener placement restriction" section. Once adhesive has
cured, remove sharp edge of fastener to allow access.
