When hydro power drops out, this harness is what keeps the battery backup pack connected to the fireplace's control system so the unit can still operate. It's a genuine Enviro replacement part, part number 50-3203 (also listed as 503203, SIT 0.584.922), and it fits 2 compatible models on record.

Purpose

The harness wires the battery holder to the Proflame 2 IFC, carrying power from the battery backup pack to the fireplace's control board during a hydro outage.

Key Benefits

• Genuine Enviro part built to the original wiring specification
• Restores reliable battery backup function for long-term use
• Direct-fit connection — no splicing or rewiring needed
• Ships new in original Enviro packaging

Other Notes

If the fireplace won't hold power during an outage, check the battery holder and connections along with the receiver before assuming the harness itself has failed — remote and backup power issues often trace back to the batteries or receiver rather than the wiring.

While you have the unit open, it's worth inspecting the receiver and remote control batteries as well, since these components share the same power path and often show wear together.
