Wiring

Fan and motor specifications are provided on the fan's type plate. All models can be adjusted and
are protected against overload current. Wires are to be connected as per the wiring diagram. For
further details, please see guidelines for the exodraft control units. All exodraft fans require extra
safeguards in accordance with power current regulations. Any lightning conductor connected to
the fan must respect current applicable legislation.

Setting up the isolation switch:
In accordance with the provisions of the EU Machinery Directive* a combustion-gas fan must
always have a fitted isolation switch. The isolation switch must comply with national wiring
standards.
* Please refer to Machine Directive (2006/42/EF/-EEC/-EWG/-CEE) – Appendix 1item 1.6.3 "Separation of thesources of
energy".
An isolation switch must be ordered separately as it is not part of the standard
exodraft chimney fan delivery.

Commissioning of the chimney fan

The chimney draught must be checked when
commissioning the fan. The pressure differential
switch might need adjusting during commissioning.
The pressure differential switch must be set so that
the fail-safe system will cut out when the volume
of flue gases falls below a set level. During such a
test, all windows and doors must be closed and
any ventilation fans switched on. Please refer to the
relevant exodraft Gas Fan Controller Installation
Instructions for guidance.
As illustrated, remove the top cover and adjust the
pressure differential switch (PDS) to the required
value.
