REPLACING THE SAFETY PROBE

Usually if a problem occurs keeping the flame alight while depressing the flame safety button, it probably indicates a fault in either the flame safety valve or the probe. There are several types of probes and various means of holding them securely to the main burner tip or the pilot. It is important to remember these main points:

• The small nut attached to the probe end must be screwed into the safety unit body by hand and then tightened 1/2 turn only. DO NOT OVER TIGHTEN.
• Approx. 5mm of the probe tip only should be inserted in the flame. Damage and loss of sensitivity can result if the probe is not correctly positioned.
• Check that the probe end that fits into the safety valve is not dirty and the thread is not damaged. There must be a good electrical type connection.
