7 CLEARANCES TO HEAT-SENSITIVE MATERIALS
The clearances shown in this section have been determined by test according to procedures set out in
safety standards AS/NZS 2918:2001 When the zero clearance wood inbuilt is installed so that its surfaces
are at or beyond the minimum clearances specified, combustible surfaces will not overheat under normal
and even abnormal operating conditions.
No part of the zero clearance wood inbuilt may be located closer to combustibles than the minimum
clearance figures given.
7.1 Positioning the Unit
It is necessary to have a floor protection made of non-combustible materials that meets the measurements
specified in table "FLOOR PROTECTION" (see Section 7.2: Minimum clearances to combustibles, and floor
protector).
Non-combustible material floor protection must be made of Bellis board or similar material with a thermal
insulance of 0.1 m².K/W per 9 mm thick and have a thickness of 9 mm. The floor protection should be 1125
mm deep (D) x 1185 mm width (W, protrude not less than 500 mm in front of the zero clearance wood
inbuilt and cover the area under the zero clearance wood inbuilt and extend beyond each side (see Section
7.2: Minimum clearances to combustibles, and floor protector).
The Stratford CF must be installed on a raised combustible or non combustible base at least 90 mm above
the floor protection. The upper and lower angle, for the full width of the floor protection, must be
protected 50 mm horizontally and vertically (E) by a non-combustible material. For example, a sheet metal
(not included). Apart from these two corners, the sheet metal does not have to cover the rest of the wall
between the base of the wood inbuilt and the floor.
