Automatically clears when 12 V supply reaches 11 V. If the voltage decreases, various error messages can
also appear. These are not genuine faults. Ensure that the boiler has the right voltage.
Fan restarts: Incorrect fan speed. New start attempt is made. Repeated faults results in Fan failure, If Fan
failure recurs after resetting, contact a dealer. If Fan restarts is displayed, no action is necessary.
Gas failure: Out of gas or gas is not igniting. Check the gas cylinder is full. Try a dierent gas cylinder,
ensuring it is propane gas. Check the gas regulator and any isolation valves are open and not frozen
Ensure that gas is available.
Overheat red fail: Overheat (red cable). Bleed the system of air. Check the fluid level in the expansion
tank. It should be 1 cm above Min mark when cool. Check the circulation pump is responding. Wait 15
mins for the fluid to cool down. This fault can arise if the boiler is run at high power at the same time as
there are air pockets in the heating system, the heating system should then be vented properly. If the
fault remains, contact a dealer.
