above the kiln, which exceeds the outer dimensions of the
kiln 1 m in each direction. In order that the surrounding
materials do not ignite, suitable fire-proof materials of low
heat conductivity should be used. Calcium Silicate
insulation boards (15 mm) are particularly suitable and
available from builders & merchants.
3.3 Checking clamps
When putting toploader kilns in operation the lid clamps on the
kiln must be checked for strength and tightened if necessary
.
The test needs to be performed during first installation and
every 6 months in the first 2 years of operation (or after 30
firings, whatever occurs first).
After 2 years of operation this check must be carried out at
annual intervals.
3.4 Connection of exhaust pipe
Generally, all kilns are supplied with an exhaust pipe of 
80mm which should be fixed with two threaded screws with
the sloped side in front of the side ventilation hole.
For a discharge to atmosphere a minimum 2 m
long (chimney effect) stovepipe (e. g. flexible
aluminium pipe
 80 mm available from
KITTEC ® ) can be connected to the end of the
exhaust pipe (suitable size metal hose clamp)
and passed through a heat-resistant fairlead
(e.g. stone or concrete) to
the other side of the wall or ceiling to
open-air in an upward direction.
Precautions should be taken to prevent
rainwater entering the exhaust pipe and
to prevent the flue being influenced by
bad wind conditions.
