DRWH-120 120V Wire Harness for MARK 10DX-117

The DRWH-120 is a 120V wire harness that mates specifically to the MARK 10DX-117 ignition module on Re-Verber-Ray DR Series NFS-2 and PFS-2 high-intensity infrared heaters. It routes 120V supply power through the MARK 10DX-117 ignition module and distributes connections to the spark electrode, the combination gas valve, and the thermostat. The electrode connection runs through a separate high-voltage orange wire (HVW-18); the gas valve connection covers VR4205M-1308 for NG or VR4205M-1316 for LP. Consolidating this inter-component wiring into a single pre-terminated assembly eliminates field splices and ensures correct wire routing per the NFS-2/PFS-2 wiring diagram.

It fits Re-Verber-Ray DR Series NFS-2 and PFS-2 heaters rated for 120V; see the Fitment panel for the full model list. The DRWH-120 is a direct replacement for the original wiring harness and cross-references to alternate numbers 4766457 and 1FEK4. Those numbers appear on distributor listings and in parts sourcing systems; confirm the match against the heater's model label and the DRWH-120 installation sheet before ordering.

Each unit ships factory-assembled as a complete, pre-terminated harness ready to install.

To replace this harness, shut off the gas supply and open (disconnect) the electrical circuit before beginning work. Disconnect the old harness from the circuit board and from all connections to the electrode, gas valve, and thermostat, then reconnect the new DRWH-120 according to the NFS-2/PFS-2 wiring diagram. Installation must be performed by a trained, qualified gas installation and service technician; improper installation can cause property damage, serious injury, or death. Verify operation after installation. See the factory installation sheet: DRWH-120 Replacement Instructions (PDF).
