Further details
| Common failure modes | blocked gas orifice, distorted flame tube, damaged thermocouple/electrode assembly |
|---|---|
| Comparison before order | compare physical length, thread type, electrode configuration with existing unit |
| Ignition sequence | spark from ignition transformer lights pilot flame; flame-sensing device confirms pilot is burning |
| Replacement factors | burner series, gas flow rate, mounting flange dimensions, flame position |
| Safety lockout | control box locks out if pilot flame lost |
Choosing and fitting
When selecting a pilot burner of this type, verify the tube diameter, length, and mounting configuration against the existing unit. Ensure compatibility with the thermoelectric safety valve (e.g., S11T) and check the gas orifice size for the specific gas type. Compare the flame position relative to the main burner head to ensure proper ignition.
Signs of failure
Common failures include blocked gas orifices, distorted flame tubes, or damaged thermocouples, leading to loss of pilot flame or weak signal. Symptoms may include failure to ignite the main burner, intermittent flame loss, or safety lockout. Check for debris, physical damage, and continuity of the thermocouple circuit.
