5. Uendeshaji
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.
