STEP DOWN ADAPTER, 110VAC/ 3VDC

Convert standard 110VAC wall outlet power to the precise 3VDC required for reliable ignition operation with Crystal Fire® Plus burners and burner inserts featuring a Direct Spark Ignition (DSI) system.

Voltage Regulation for Safe DSI Operation

Direct spark ignition control boards cannot process standard household alternating current. This step down adapter safely transforms 110 volts AC to 3 volts DC, delivering stable low-voltage power that protects sensitive microprocessors while ensuring consistent ignition spark generation. Supplying incorrect voltage to a DSI module typically causes control board failure, blown fuses, or complete loss of ignition. This component bridges the gap between residential wiring and the fireplace’s internal electronics.

Exact Match for Crystal Fire® Plus Components

Factory-calibrated specifically for Crystal Fire® Plus burners and matching burner inserts, this adapter eliminates cross-compatibility errors during replacement or repair projects. The specified output matches the exact voltage rating and ground isolation required by the native DSI harness, preventing arc tracking, erratic lighting cycles, and premature electronic wear.

Verify your existing configuration before ordering: ensure your unit is a Crystal Fire® Plus burner or inserts assembly equipped with a Direct Spark Ignition system. The adapter routes between the dedicated wall circuit and the ignition control harness. Do not attempt to use this step down converter on units relying on millivolt generators, standing pilot assemblies, or electronic hot surface igniters without built-in DSI regulation.
