7.4 REDUCINGWALLANDCEILINGCLEARANCESSAFELY
You may decrease the minimum
clearances to heat‐sensitive materials
by installing heat radiation shields
between the walls or the ceiling and
the wood fire.These heat radiation
shields must be installed permanently,
and must be made of a heat‐resistant
orheat‐tolerantmaterial.
An air gap must separate the heat
shield from any heat‐sensitive surface.
Furthermore, the heat shield shall
extend in all directions beyond the
boundaries of the appliance surface by
a distance of not less than 450 mm.
Exceptionsmayapply.RefertoAS/NZS
2918:2001.
