The RBI RBI-44-0056 is a genuine OEM ignition wire assembly designed for use in RBI heating appliances. It features one straight boot and one angled boot, allowing it to route cleanly to the igniter in applications where a straight connection on one end and an offset connection on the other are required. This wire delivers consistent spark transfer from the ignition control to the igniter electrode, supporting reliable burner startup. HVAC technicians install this part as a direct OEM-matched replacement when an ignition wire shows cracking, carbon tracking, or resistance failure during routine service.
This ignition wire is suited for residential and light commercial heating units where RBI equipment is installed. Compatible models listed by the manufacturer include the UDAP 30, TR 75/100, and UDAP 75. The angled boot design accommodates tight clearances common in unit heater and boiler configurations, making routing straightforward without stressing the wire jacket or boot seal.
Compatible with RBI models UDAP 30, TR 75/100, and UDAP 75 as stated by the manufacturer. Verify the boot configuration and wire routing against the unit wiring diagram before installation.
A licensed HVAC technician should perform this replacement. Shut off electrical power to the unit at the disconnect switch before removing the existing ignition wire. Inspect the igniter electrode and ignition control terminals for carbon buildup or corrosion before installing the new wire. Route the wire clear of sharp edges, hot surfaces, and moving components to prevent premature jacket wear.
