HVAC CONTROLS Gas Pilot Ignition Systems

OEM Replacement Pilot Relite Control • Will spark until flame is sensed between electrode and ground • Relite control detects flame through flame conduction

• If flame is extinguished during call for heat, relite control will begin sparking the instant the flame goes out Specifications: • 0.03A, 24VAC — 1/4" male spade terminals • High voltage connection — 1/4" male spade WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

• When flame current is sensed between electrode and pilot burner ground, relite control stops sparking
