Ensure that the element is correctly placed: the thin part of the element legs should be
entirely within the heating chamber; the element should not touch the bottom of the
chamber. A guide to the correct placement is given in the table below, using the
measurement from the top of the clamp to the top of the element.
Replacement: heat up the furnace to a moderate temperature and ensure that the
furnace is controlling properly, in case the previous element failure resulted from a fault
in the control system.
After installing new elements operate the furnace at 1500 °C for an hour. This creates a
protective glaze on the element surface.
Element Fitting Layout
Use of Clip Tool
The distance from the top of the element clamp to the top of the element should be
40 mm.
