The integrated NEMA 4X enclosure provides superior protection against corrosion and environmental ingress

Zero Leakage: Tight shut-off prevents energy loss and Ghost Flow in complex hydronic circuits

because this is a power closed spring open model

ensuring that the combustion blower is moving enough air to safely vent flue gases before the ignition sequence initiates

providing excellent resistance to oils and gases typically found in industrial burner systems
