5. Fonctionnement

The Blodgett 20348 Spark Box Assembly operates automatically as part of your oven's control system. When the oven thermostat calls for heat, the assembly receives a signal to initiate the ignition sequence. It then generates a high-voltage spark at the igniter electrode, which ignites the liquid propane gas flowing to the burner. A flame sensor confirms successful ignition, allowing the burner to continue operation. If ignition fails, the assembly will attempt to reignite or enter a lockout state, depending on the oven's control logic.

6. Entretien

The Blodgett 20348 Spark Box Assembly is designed for durability and typically requires minimal maintenance. However, periodic inspection is recommended:

• Inspection visuelle : Annually, or as recommended by your oven's service schedule, visually inspect the assembly and its wiring for any signs of wear, corrosion, or damage.
• Propreté: Ensure the area around the spark box is kept clean and free from dust, grease, or other debris that could interfere with its operation or cause overheating.
• Remplacement des composants : Do not attempt to repair the spark box assembly. If it is found to be faulty or damaged, replace it with a genuine Blodgett 20348 part to ensure continued safety and performance.

7. Dépannage

The spark box assembly may indicate operational status or errors via an LED light. Refer to the labels on the unit for specific error codes:

• SOLID RED LED: Indique un fonctionnement normal.
• NO FLAME DURING TRIAL FOR IGNITION: If the burner fails to ignite, check the gas supply to the oven, verify the igniter electrode is clean and properly gapped, and ensure the flame sensor is functioning correctly.
• INTERNAL ERROR: If the LED indicates an internal error, the spark box assembly is likely faulty and requires replacement.

If the oven fails to ignite or experiences intermittent ignition issues, consider the following:

• Vérifiez que le robinet d'arrivée de gaz est ouvert.
• Check all electrical connections to the spark box assembly for tightness and correct wiring.
• Inspect the igniter and flame sensor for damage or carbon buildup.
• Si les étapes de dépannage ne résolvent pas le problème, consultez un technicien de maintenance qualifié.
