FLOOR PROTECTOR
If the wood fire is to be installed on top of a combustible floor, it must be guarded by a non
combustible material as shown on the dotted line area of the above figures. Install a 1100 mm (W)
x 300 mm (D) floor protection of 9 mm of thickness with thermal conductivity of 0.1 m
2
K/W per 9
mm thick.

*Bellis board, cement fibre sheet or similar. No protection is required if the unit is installed on a
non-combustible floor (ex: concrete).
**The floor protector shall extend not less than 200 mm from each side of any ash removal or
fuel loading openings unless the floor protector forms an abutment with a wall or heat shield at
a lesser distance.

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.
Following the installation of such heat radiation shields, the minimum clearances to heat-sensitive
materials may be reduced by applying the clearances factor in the table below:
