Parts to Your Door 54247 Flame Sensor Peerless Boiler

Product Description

The PARTS TO YOUR DOOR 54247 is a flame rectification sensor probe designed for use in Peerless PF-series boilers. Flame rectification sensors detect the presence of a burner flame by passing a small electrical current through the flame and returning a microamp signal to the boiler control board. If no signal is detected, the control board locks out the burner as a safety measure. This probe ships with a gasket and two mounting screws, giving the technician everything needed to complete the swap without sourcing additional hardware. It is installed by licensed HVAC technicians and boiler service professionals during routine maintenance or combustion-control troubleshooting.

This sensor is a direct replacement part for Peerless PF-series gas-fired boilers, specifically the F50, F80, F110, F140, F210, and F399 models. It is suited to residential and light-commercial hydronic heating applications where reliable flame sensing is critical to safe burner operation. Technicians typically encounter this part during annual tune-ups, after nuisance lockouts caused by a contaminated or failed sensor, or as part of a combustion control system repair.

Compatibility

Compatible with Peerless PF-series boilers: F50, F80, F110, F140, F210, and F399. Verify boiler model and existing sensor mounting configuration before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified boiler service professional. Shut down the boiler and allow it to cool completely before removing the existing sensor. Inspect the gasket seating surface for corrosion or debris and replace the gasket included with this part. After installation, verify flame signal microamp reading at the control board using a multimeter to confirm proper sensor operation before returning the boiler to service.
