The 50V51-843 is a two-stage automatic gas interrupted ignition control employing a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner and inducer. It provides signals for proper operation of a variable fan speed circulator blower. Signals interpreted during continual surveillance of the two-stage thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shutoff during normal operation. The control incorporates system fault analysis for quick gas flow shutoff, coupled with automatic ignition retry upon sensing a fault correction.

 

IMPORTANT: Heating, ventilation, air conditioning or refrigeration parts and accessories should only be installed by qualified technicians. Failure to understand and follow the manufacturer's installation and use instructions may result in fire or explosion, electric shock, property damage, injury or loss of life. It is your responsibility to seek professional advice when installing and using these parts and accessories.
