Pb Heat 90836 Burner Wiring Harness WBV-03 Riello

Product Description

The PB HEAT 90836 is a burner wiring harness designed for use in hydronic heating systems. It includes an EAD (Electronic Air Damper) connection and provides the electrical interface between the burner controls and the boiler system. This harness is a direct-fit component engineered for the WBV-03 boiler platform paired with a Riello burner. Installation is typically performed by licensed HVAC or hydronic heating technicians during burner service, controls replacement, or full boiler commissioning. The 90836 weighs 26 pounds and ships as Carton 20, with reference number 20186378 for cross-referencing with Peerless documentation.

This wiring harness is intended for residential or light commercial hydronic heating applications where a WBV-03 series boiler is installed with a Riello burner assembly. It is used when the original harness shows signs of heat damage, insulation failure, failed connections, or when a full burner controls assembly is being replaced. Proper harness routing and secure connector seating are essential for reliable burner ignition and safe system operation.
