1 bar
No flame detected
Possible Cause: Empty gas bottle or blockage in the gas line, or low temperatures affecting gas vaporization.
Check gas supply making sure there is gas in the bottle and no blockage in the gas line. At temperatures below 5°C, use Propane gas rather than Butane. Clear lockout by turning the d.c. power off and on again, or press the red Reset Button on the Water Heater if required.DIY Safe
