1.1 Models Covered by this Manual
This manual covers the Carbolite furnace models ELF 11/6B and ELF 11/14B. The B suffix
indicates differences from earlier models, in particular that the heating element is enclosed in an
inner metal chamber, and the heating wires are partly exposed in the chamber sides and radiate
freely into the chamber. The B models were not made before mid-2001.
The B versions also allow for a simple customer adjustment to increase the air flow through the
chamber. Carbolite do not claim that this adjustment makes the furnace suitable for ashing or
burn-off applications.
The B versions may be set to operate on any single-phase voltage in the range 200-240V (or 100-
120V to order) by correct setting of the power limit parameter in the controller.
Because of model changes it is very important when ordering spares to state the furnace serial
number or otherwise to identify the model correctly.
