NON-COMBUSTiBLE fACiNG MATERiAL

WARNING: Non-combustible facing material must not project more than 4" (102mm) from the face of
the door (all three sides). If greater projections are desired, increase the clearance to the sides and
top by 2" (51mm) for every additional 1" (25mm) 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.

ALCOvE CLEARANCES

NOTE: Recesses or alcoves above the appliance can be made as deep as desired provided the minimum
clearances to combustibles are maintained.
Non-combustible material can be used, provided the minimum clearances to combustible materials are applied.
The minimum enclosure volume must be increased by no less than the volume of the recess. This adjustment
can be made by increasing any or all of the height, width and depth of the enclosure.
