Commissioning The Appliance
Pre-Commissioning Checks
Prior to undertaking the commissioning of the unit please ensure that the system water has been
cleansed and treated with a suitable inhibitor as detailed in Filling the System and System Water Quality.
Prior to applying power to the appliance its circulation pump (10) should be bled and checked to ensure
free rotation of the armature and the automatic air vent (a) should be opened and allowed to vent the
heat exchanger and associated pipework. Better access to the pump can be achieved by removing the air
duct from the fan inlet Venturi.
Also ensure that the ignition electrodes spark gap is set to 4mm.
