LPG (propane)
Do not operate the appliance if the measured value is below or
above these values. Determine the cause and eliminate the fault. If
this is not possible, block the appliance on the gas side and notify
the gas supplier.
▶ Repeatedly press the emissions test button
The display returns to the supply temperature.
▶ Switch the appliance OFF, turn off the gas cock, remove the pressure gauge and
