Eclipse

Ignition electrodes (such as 00.7030022.01 and R1/4x43 types) generate a spark to initiate fuel combustion, requiring high-voltage (typically 4–10 kV) pulses from an ignition transformer. Ionization probes (e.g., reference 10002242-1) detect the presence of flame after ignition by measuring ion conductivity in the combustion zone, feeding a signal back to the burner control system. Ignition electrodes are consumable and subject to erosion; probes are typically longer-lived but must be positioned in the flame envelope.

Start with your equipment's original service manual or nameplate, which should list the Eclipse reference number (e.g., 00.7030022.01 or EC23045). If the reference is unknown, note the thread pitch (M14, R1/4"), overall length, and electrode gap distance, then cross-reference with Eclipse's technical documentation or contact us with a photograph and burner model number. We hold SKUs for common industrial burner platforms and can assist with dimensional matching.

Common failure modes include carbon buildup or fouling (caused by incomplete combustion or fuel contamination), thermal shock from rapid on-off cycling, mechanical vibration leading to crack initiation at the threaded base, and incorrect electrode gap setting. High-frequency ignition demand, water ingress into the electrode cavity, and exceeding the transformer voltage rating accelerate wear. Regular inspection and cleaning during scheduled maintenance extend service life; replacement intervals vary by duty cycle and fuel quality.

No. Eclipse industrial spark plugs (e.g., EC23045 M14 L=101mm) are designed for burst-ignition service in burner controls, not continuous automotive ignition. The electrode gap, insulator material, and thermal range are optimized for combustion-chamber pressure and temperature profiles specific to industrial furnaces and boilers. Using automotive plugs in industrial equipment may result in misfire, fouling, or thermal damage.

Eclipse reference numbers encode design revisions and dimensional variants. The suffix (.01, .02) typically indicates a change in electrode gap, wire diameter, insulator material, or thread geometry. Without access to Eclipse's full technical matrix, we recommend verifying compatibility against your equipment OEM documentation or submitting a photo of the removed electrode to confirm the exact replacement.

Ignition electrodes may be safely cleaned of light carbon deposits using a soft brass brush and solvent in a well-ventilated area, but erosion of the electrode tip itself cannot be reversed. Once the gap widens beyond the design tolerance (typically 0.8–1.2 mm), spark reliability declines and replacement is necessary. Ionization probes should not be sanded or filed, as damage to the ceramic insulator may cause leakage current and false flame signals.
