check existing electrical installations (fuse box, supply
and sockets) and for sufficient size of fuse and thickness.
To guarantee a fast and easy disconnection from the
power supply for the kiln in case of emergency, the
main isolator switch on the electrical supply should be
readily accessible within the kiln room.
Do not connect kilns with 230 volt nominal capacity to
any socket, before an electrician has checked all the
above mentioned points. For kilns with 400 volt nominal
capacity different regulations apply. Check with your
electrician.
Under no circumstances use an extension lead!
Connection of exhaust pipe:
All kilns with 400 volt nominal capacity are supplied with
exhaust pipe which should be fixed with two threaded
screws with the sloped side in front of the side
ventilation hole. A minimum 2 m long (chimney effect)
stovepipe (e. g. flexible aluminium pipe
∅
70 or 80 mm
available from builders & merchants) can be connected
to the end of the exhaust pipe (suitable size metal hose
clamp)
and passed through 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 .
The first firing (test firing)
Each new kiln has to be fired empty prior to normal use.
This is necessary for three reasons:
•
Checking the function of the kiln and controller
•
To extend the life of the heating elements they need
the protection of an oxide layer provided by an empty
first firing.
•
The insulating fire bricks of the kiln may still contain
moisture residue, which has the opportunity to dry
during the slow increase in temperature during this
first firing.
