Utica-Dunkirk 33421001 Burner Tube 321894-709 Reliable Construction: High-grade materials resist

Reliable Construction: High-grade materials resist vibration and pressure-induced stress

A reading of "OL" or high resistance outside the 10-20 ohm range indicates the silicon carbide has reached its end of life

Precise Flow Direction: Minimizes bypass leakage between suction and discharge lines to maintain system SEER and EER ratings

a run capacitor is required for operation
