2 INSTALLATION
If the furnace has been transported or stored in humid conditions it must be dried out to restore its
normal condition before completing the installation (see Section 9.2 page 25 for the drying out
process).
2.1 Unpacking & Handling
When unpacking or moving the furnace, always lift it by its base or by both ends of the main
body. Never lift it by the end insulation or by a work tube. It may take 2 or 3 people to lift the
furnace, depending on size and configuration.
Remove any packing material from inside the furnace before use.
NOTE: This product contains refractory ceramic fibre (an alumina silicate material).
See section 5.2 page 19 ‘Repairs and Replacements’ for precautions and advice in handling this
material.
2.2 Siting
See Section 9.2 page 25, for Environment conditions before siting the furnace.
Place the furnace in a well-ventilated room, away from other sources of heat, and on a surface
which is resistant to accidental spillage of hot materials. Do not mount the furnace on an
inflammable surface or close to any inflammable walls, ceiling or stored materials.
Ensure that there is free space of at least 300mm all around the sides and 1500mm above the
furnace.
If the furnace is to be used in a process which could liberate hazardous gases, then it
should be installed together with a suitable fume extraction system. A direct connection to the
furnace chimney should not be made. Do not obstruct any of the vents in the control box as they
are required to keep the controls cool. Ensure that the furnace is placed in such a way that it can
quickly be switched off or disconnected from the electrical supply.
