Greenheck 385214 Transformer 321042-401 always check the flame sensor

always check the flame sensor and ignition module as well

This component is essential for installations requiring non-interrupted burner operation exceeding 24 hours

ensuring responsive valve modulation even in high-pressure drop configurations

Standard plumbing practice dictates that the thermal element must be immersed in the top 6 inches of the tank

maintaining constant head pressure even during fluctuating load conditions

Greenheck 385214 Transformer 321042-401 always check the flame sensorThe Greenheck 385214 Transformer is a field proven solution for converting 120V primary voltage to a stable 24V secondary output.
