Ignition Electrode Spark Gap: Calibration and Mounting Alignment Guide

The ignition electrode is a tiny part with an outsized effect on the customer experience. A stove that clicks without lighting is one of the most common complaints repair shops hear — and the root cause is almost always a wrong spark gap or a misaligned electrode. For parts distributors, selling the right electrode is only half the job; understanding the calibration that makes it work is what earns repeat trust.

Why Spark Gap Matters

The spark gap is the distance between the electrode tip and the burner surface it arcs to. Too wide, and the spark is weak or absent. Too narrow, and the arc shorts or lights poorly. The correct gap concentrates the high-voltage discharge into a crisp, reliable spark that ignites the gas-air mixture on the first click.

Typical Spark Gap Specifications

• 3–5 mm — the common working range for most SABAF-compatible burner systems.
• Ceramic insulator — must be intact and clean; a cracked insulator leaks voltage and weakens the spark.
• Electrode position — the tip should sit just above the burner ports, in the gas flow path, not buried or shielded.

Mounting Alignment Best Practices

An electrode that is bent, loose, or angled wrong will misfire even with a perfect gap. The tip must point squarely at the target surface, the bracket must hold it firmly, and the ceramic body must be clear of metal contact except at the mounting point. When installers follow these rules, ignition reliability jumps and warranty returns drop.

Sell the Fix, Not Just the Part
