SECTION 2 - POSITIONING ELECTRIC KILNS
The kiln should be installed in a well-ventilated (but not drafty) area, on a clean, flat, non-
combustible surface (such as concrete or cement sheet), with adequate space around the kiln for
the natural circulation of air. Nothing should be resting against the sides of the kiln, stored under
the kiln or on top of the kiln. There should be no flammable or combustible materials stored in the
room or area where the kiln is situated.
It is recommended that there be a minimum gap of 150 mm of wall on the non-control box sides
and 600 mm of wall on the control box side, where the walls are of a non-combustible material
(such as steel sheet, brick or cement sheet). If the walls are of potentially combustible material
(including but not limited to wood or plasterboard), a minimum of 300 mm is recommended for the
non-control box sides and 600 mm for the control box side.
There should be ample clearance from the top of the kiln to the ceiling or roof (at least 1000 mm),
and any flue (if fitted) should be installed by a qualified provider in such a way as to prevent
contact with flammable or combustible substances. In any event, the kiln should not be situated
below a combustible roof or ceiling.
2.1 POSITIONING OF KILN OUTSIDE IN A SHED
If the kiln is to be positioned outside of a building, it is vital that there is a structure around
the kiln to shield it from weather conditions, such as rain, wind and humidity. If the kiln is
exposed to moisture, the bricks will absorb the moisture and, when firing the kiln, the
moisture will disperse from the brickwork causing reduced life of the bricks. It should also
be noted that the performance of the kiln will be adversely affected by wind and drafts.
