Observation:
Reset appliance if required.
(Press and hold the power button for 4 seconds then release)
Allow the fan purge to complete (fan will stop running approximately
20 seconds after power is reinstated)
Apply a CH demand and allow the fan to run, monitor the pressure registered while the fan runs and the boiler attempts to ignite.
As the appliance goes through repeated ignition attempts the fan pressure measured should drop to approximately 0mb (during the sparking stage of the ignition cycle).
Does the fan pressure behave as described above?
