Product Overview
The Re-Verber-Ray TP-78B is a Molex connector with attached wiring, also listed under alternate part number 4255048. It carries the signal path between the ignition control board and the direct-sense flame-detection circuit on Re-Verber-Ray non-flame-rod tube heaters. Direct-sense ignition proves burner flame through this circuit instead of a separate flame rod, so a loose or damaged connection here typically shows up as an intermittent ignition fault or a control-board lockout.
It fits Re-Verber-Ray DTHS-3, DX, DBS, and DRV series direct-sense tube heaters; see the Fitment panel for the full model list.
It ships as a complete connector-and-lead assembly, ready to wire into the heater's direct-sense ignition circuit.
Replacing this part: shut off the gas supply and disconnect electrical power to the heater before servicing. Match wire gauge and connector pin orientation to the original before reconnecting, and have a qualified technician verify ignition operation and confirm safe burner startup after installation.
