9.7 installing non-combustible board
Non-combustible facing material must not project more than 4” (101.6mm) from the face of the door (all four
sides). If greater projections are desired, increase the clearance to the sides, bottom and top by 2” (50.8mm) for
every additional 1” (25.4mm) of projection. If using an optional surround, the same rule applies, starting from the
top of the surround. Ensure clearances are maintained for surround removal, as it must lift off the appliance for
maintenance.
!
WARNING
Non-combustible top:
• Align pre-drilled holes in the non-combustible board with
the pilot holes in the sheet metal.
• Secure the non-combustible panel to 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 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 finish coat. Light coloured paints may discolour.
Do not notch the framing around the appliance
standoffs. Failure to maintain air clearance space
could cause overheating and/or fire.
