If your kiln is fitted with electronic heat fuse this is automatic and if it requires reset please contact ourselves , failure to do so could damage the kiln , we need to check the reason for failure .
KILNS AND R.C.D. “TRIPS”
Due to the structure of kilns a certain amount of leakage to earth will probably be evident, therefore the fitting of a 30ma R.C.D. in the circuit can create a fault condition at higher temperatures, when first fired or used after a long period of inactivity. This problem is relatively rare but can be solved by the fitting of a 100ma R.C.D. consult us or a fully qualified electrician for advise.
Before using the kiln it is advisable to fire the kiln empty to a temperature of 700 degrees centigrade at a rate of around 200 degrees per hour. This will dry and “settle” the kiln. The kiln is pre-fired to 750 degrees centigrade at our factory shortly before despatch and so, depending on the time delay between delivery and installation, the amount of moisture drawn from the atmosphere by the kiln may well be minimal. On the initial firing, a slight odour may be emitted, this is the remnants of binding resins in the boards and should stop after one or two firings. One reason that we pre fire the kiln is to minimise the amount of resin odour left in the kiln before the customer receives the kiln.
We suggest that the kiln controller is set to fire the kiln to a low temperature and end, say 150 degrees, whilst being monitored to ensure that it is switching off the kiln and that no problems have occurred during transport.
Kiln batts sufficient to cover the base elements and provide a loading platform were included with your kiln. Position these so that there is even space all round with a gap in the middle (if two or more batts).
Additional shelves are created by using three or four prop columns spaced equidistantly to
evenly support single shelves and four or five prop columns to support shelves consisting of
two batts. All prop columns should be placed so that their weight acts down over prop columns below. It is best to use base supports and collars to spread the load where shelves have two or more batts
Before batts are used they should be thoroughly dried and sounded. A dry batt can be supported by hand at its centre or suspended between thumb and finger and tapped with a metal object. If it does not ring a crack may be suspected. A dull sound suggests the batt is not dry. Store batts on edge in a dry place.
Use of batt wash
If satisfactory the upper surface of each batt should be painted with batt wash mixed with water to a thin, creamy brushing consistency. Sufficient should be painted on to cover the batt without show-through. Periodic replacement of this coat will be necessary. Do not paint props or any kiln brickwork with batt wash. Allow batt wash to dry before loading ware and be careful to avoid transferring traces of batt wash on fingers etc. to the ware.
There is a bung located on the kiln roof this should be used to allow moisture to be released from the interior during the earl firing process and should be replaced after the kiln has reached 600 degrees centigrade. This bung can be removed to speed up the process of cooling .
There is a spy hole bung located on the door , this is to allow inspection of the chamber during the firing the operator must TAKE CARE when using this as this will allow heat to escape and safety equipment such as darkened lenses should be used.This bung should NOT be used to cool the kiln .
When cooling the kiln the door should NOT be opened above 80 degrees centigrade , above this temperature you could damege the kiln and pottery pieces would crack.
Only qualified personnel should operate this equipment.
WE ARE PLEASED TO INSTRUCT ANYONE BUYING A KILN FROM US , ON HOW TO USE IT.
SERVICING THE KILN.
The kiln should be inspected annually by ourselves. Any work should be carried out by us as this is a specialist piece of equipment , and we have the specialist knowledge and equipment to maintain kilns .
We have in stock ALL the spare parts for the kiln, We pride ourselves on our back up and after sales service and so in the unlikely event of any problems please do not hesitate to call our staff for friendly help and advise.
Your kiln is supplied ready for connection to a 3-phase supply.As always we recommend that the connections are done by a qualified electrician.
REMEMBER the kiln bricks are of ceramic composition and as such severe shocks to the chamber must be avoided.
It is important that the earth bonding wires are re-fitted correctly and soundly.
Before final connecting it is advised that all electrical connections are checked and re-tightened by a competent person.
