Igniter electrode gap at a burner port Ceramic insulator, metal tip aimed at a burner port. Spark gap about the thickness of a nickel. SIDE VIEW · ELECTRODE GAP burner tube ports ceramic lead tip spark gap ≈ nickel ~1.8–2.1 mm to a port Tip aims at a port, not the tube wall. Cracked ceramic = replace.

Napoleon Rogue 425 is a 3-main 42k-class cart. Ignition is electronic spark, not a Weber AA Spirit box. On Rogue / RXT / RSE-1 schematics Napoleon lists N357-0021LY (2-spark 4.5V block) and N240-0040 (90° electrode with 29” lead — often the rear / IR ceramic on RSIB). Main-tube ceramics and N240-0026 side-burner electrodes are different SKUs. Prestige LED buttons (N660-0013) are not Rogue-base parts unless your panel actually has them.

We do not invent Amazon ASINs for these. Search BBQGuys and Amazon for the OEM number on your schematic. Plate.

Procedure

  1. Read Rogue 425 vs Rogue SE 425 RSIB vs Rogue PRO-S. Rear IR and side IR change electrode count.
  2. Lid open. Hold the igniter. Rapid tick. No tick: battery in the module, then N357-0021LY-class block.
  3. Tick, no snap at one burner: that ceramic. Mains live, rear IR dead: N240-0040-class, not a main tube electrode.
  4. All snap, no fire: regulator reset.
  5. Tank off. Grates and sear plates out. Photograph each ceramic bend (90° vs straight) and lead length.
  6. Pull the boot at the module. Replace one electrode. Nickel gap at the factory tab on the N100-0060 18-gauge main tube.
  7. Do not reuse a cracked porcelain. Vacuum shards so the next spark does not short to the box.
  8. Test lid open. Side burner: N240-0026 if that is the dead ceramic.

FAQ

What OEM igniter is a Napoleon Rogue 425?

Module N357-0021LY on many Rogue/RSE years. Electrodes are location-specific: N240-0040 (90° / 29” lead, often rear IR), N240-0026 (side). Confirm the exploded view for your RSIB vs base 425.

Can I use a Weber 7642 kit?

No. Different voltage, connectors, and cook box.
