Description
The Rheem-Ruud RTG20223M is an OEM replacement flame rod with blue wire, engineered to deliver precise and dependable flame detection in Rheem-Ruud water heating systems. Proper flame sensing is critical to safe and efficient operation — a faulty or degraded flame rod can cause nuisance lockouts, ignition failures, or unsafe burner conditions. This direct-fit replacement restores your system to factory performance quickly and reliably.
Product Overview
The flame rod works by passing a small electrical current through the burner flame. Because a flame conducts electricity, the control board uses this signal to confirm that combustion is occurring. If the flame rod is fouled, cracked, or worn, the signal degrades and the unit may shut down on safety lockout. Replacing the flame rod with a genuine Rheem-Ruud part ensures the correct signal characteristics and connector fit for your specific appliance.

Why Replace Your Flame Rod?
Over time, flame rods accumulate oxidation and carbon deposits that insulate the sensing tip, weakening the microamp signal returned to the control board. A weak signal causes the board to interpret a no-flame condition, triggering safety shutdowns. Regular inspection and timely replacement of the flame rod keeps your system running without interruption.
