IGNITION LOCKOUT
The appliance will enter a lockout condition in the event of the
burner failing to ignite.

air flow fault.
If the controls fail to detect the correct air flow through the
appliance the electricity supply to the gas valve will be interrupted.
If an air flow fault has occurred, the domestic water demand
indicator will flash (approximately five times per second).
The appliance will try to re-light after a waiting period of
approximately 4 minutes Check that the flue terminal has not been
obstructed or damaged. If this condition continues to occur, then call
a service engineer.
FLUE SPILLAGE DEVICE (OF ONLY)
The appliance is fitted with a device which detects the spillage
of combustion products from the draught diverter. In the event of the
flue becoming wholly or partly blocked this device will cut the gas
supply to the burner. If the device has activated, the D.H.W. demand
indicator will flash (approximately 5 times per second).
The device automatically resets after a waiting period of approxi-
mately 20 minutes. If the blockage remains the appliance will re-light
briefly before the device operates again. Should the problem persist
consult your service engineer.
