What should a G-3 technician do if they notice flame roll-out upon reactivation of an appliance?

  1. Continue operation and monitor

  2. Turn off gas supply and call a qualified technician

  3. Adjust the burner settings

  4. Check the water level in the boiler

The correct answer is: Turn off gas supply and call a qualified technician

When a G-3 technician observes flame roll-out upon reactivation of an appliance, it is crucial to prioritize safety and address the underlying issue. Flame roll-out indicates that flames or hot gases are escaping from the combustion chamber, which can pose a serious risk of fire or explosion. Turning off the gas supply and calling a qualified technician is the appropriate action in this scenario. This step ensures that the appliance is no longer using gas while problems are assessed and rectified by someone with the necessary technical expertise. A qualified technician will be able to conduct a thorough inspection, diagnose the cause of the flame roll-out, and perform any necessary repairs or adjustments to ensure safe operation. Continuing operation and monitoring, adjusting burner settings, or checking the water level in the boiler could lead to hazardous situations. These actions do not address the immediate danger posed by the flame roll-out and may further jeopardize safety. Therefore, ensuring the gas supply is turned off and involving a qualified technician is the most responsible and safe course of action.
