A Rheem SP21223 Flame Rod Triton verifies burner flame presence and relays ignition status for dependable performance in the unit.
The flame rod triton detects burner flame presence and signals the control system so the heating and cooling unit can maintain safe ignition and normal heating operation. Its construction matters because a properly built flame rod resists heat and combustion exposure while providing reliable flame sensing for consistent HVAC system performance.
The flame rod triton may need to be replaced if the heating and cooling equipment shows ignition failure, intermittent burner shutdown or inconsistent heating cycles caused by weak flame sensing. Physical signs can include corrosion, soot buildup, cracking or discoloration and environmental signs may include damage from prolonged high heat, moisture or combustion residue exposure.
