Hydrotherm GX-82762 Flame Rod

The Hydrotherm GX-82762 is an OEM replacement flame rod designed for use in Hydrotherm boiler and burner systems. Flame rods — also known as flame sensing electrodes — play a critical role in combustion safety by detecting the presence of a burner flame through the principle of flame rectification. When the burner fires, the flame rod passes a small electrical current through the flame to confirm ignition; if no flame is detected, the burner control shuts down the gas valve to prevent unsafe conditions.

Replacing a worn or failed flame rod restores proper flame sensing performance and helps prevent nuisance lockouts, failed ignition sequences, and potential safety hazards. This direct OEM replacement ensures compatibility with the original equipment specifications of your Hydrotherm appliance.

Key Features

• OEM replacement flame rod for Hydrotherm boiler and burner systems
• Enables flame rectification-based flame sensing for combustion safety
• Signals the burner control to shut off gas supply if no flame is detected
• Helps eliminate nuisance lockouts caused by a degraded or failed flame sensor
• Direct replacement for original equipment — no modifications required

Application

• Compatible with select Hydrotherm boiler and heating appliance models
• Designed for use with Hydrotherm burner control systems

Why Replace Your Flame Rod?

Over time, flame rods can accumulate oxidation and carbon deposits that degrade their ability to conduct current through the flame. This leads to intermittent or failed flame sensing, causing the burner to lock out even when ignition is successful. Replacing the flame rod with a genuine Hydrotherm OEM part restores reliable operation and extends the service life of your heating system.
