If the chimney is supplied unfitted, then fit it into the hole in the top of the furnace case. If the
furnace is to be used to heat substances which emit fumes, then a fume extraction duct of about
150mm inlet diameter may be placed directly above the chimney outlet. Do not make a sealed
connection to the furnace chimney as this causes excessive airflow through the chamber and
results in poor temperature uniformity.
2.3 Hearth Tile
The cast hearth is packed separately and should be fitted into the recess in the bottom of the
chamber before the elements are fitted (See Photo)
2.4 Heating Elements
The Silicon Carbide elements are VERY FRAGILE and are packed separately. Fit them according to
the instructions in section 5.7.
2.5 Electrical Connections
Connection by a qualified electrician is recommended.
Check the furnace rating label before connection. The supply voltage should agree with the voltage
on the label, and the supply capacity should be sufficient for the amperage on the label.
The supply should be fused at the next size equal to or higher than the amperage on the label. A
table of the most common fuse ratings is also given in section 8.1 of this manual.
The furnace is supplied with a 16 amp IEC plug and should be connected using a suitably rated
mains cable.
Connection by line plug: the plug should be within reach of the operator, and should be quickly
removable.
Connection to isolating switch: this should operate on both conductors (single phase).
The supply MUST incorporate an earth (ground).
