Error Red indicator lamp 'Fault' is lit / No flame within 60 seconds: The automatic ignitor switched off because no flame was produced within 60 seconds or gas supply was interrupted by the overheating switch.

Turn the control knob to '0' first. Then relight the heater: turn the knob to any thermostat setting from 1 to 10 and push it right down - the automatic ignitor sparks (you'll hear it) until the flame catches - and keep it held down for another 10 seconds so the safety pilot can take over.

Error Red indicator lamp 'Fault' flashes: Supply voltage has dropped below 9 V.

Charge the battery to ensure fault-free operation.

Error Heater keeps going out in windy locations or winter: Wind conditions or low temperatures are adversely affecting the exhaust system or flame stability.

Fit an AKV cowl extension (part no. 30010-20800), and remove it again before the vehicle sets off.
