2.1 Unpacking & Handling
When unpacking or moving the furnace always lift it by its base. The furnace contains a
transformer and is heavy: use two or more people to carry it. Some models may alternatively be
lifted by fitting lifting bolts to captive threads in the top of the case.
Remove any packing material.
NOTE: This product contains Refractory Ceramic Fibre (better described as Alumino Silicate
Wool) for precautions and advice in handling this material see the ‘Repairs and Replacements’
section.
2.2 Siting & Setting Up
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.
Ensure that there is free space around the furnace. Do not obstruct any of the vents in the case:
there are cooling fans in the case which must not be obstructed.
Ensure that the furnace is placed in such a way that it can be quickly switched off or disconnected
from the electrical supply - see below.
2.3 Fitting the Chimney & Heating Elements
Wear eye protection when handling the heating elements. See the warning in section 5.6.
The Molybdenum Disilicide elements are EXCEPTIONALLY FRAGILE and are packed
separately, together with other items as shown in the list.

Transit Clamps – dependent on model: the example
shown here is for the 3 litre models; remove any
transit clamps as shown. Fit the ceramic chimney to
the hole that exits the top of the chamber. Most
models are supplied with an insulation piece to fit
around the chimney; fit this insulation. For the BLF
18/8 the insulation is positioned under the roof
support frame and will need moving into position
once the transit clamp is removed.
Remove the complete top access panel using the
hidden screws in holes in the top of the panel:
loosen the screws two turns and remove the panel
Fit the heating elements vertically into the chamber.
Handle the elements with great care. The
installation of these elements is described later in
this manual.
