  • Page 33: Function

    8. FUNCTION 8-1. Motion Explanation 8-1-1. Heating Heating operation begins with the refrigerant pump down cycle to move refrigerant into the heating circuit of the system. Simultaneously, gas burner ignition is initiated for a period of about 1 minute. When the refrigerant transport period is completed, refrigerant is contained within the heating circuit tubing and retained there by the 2 check valves.
  • Page 34 8-1-3. Combustion Control (1) Combustion Combustion air is supplied into the burner for 20 seconds prior to ignition. The variable speed combustion air blower motor speed is sensed and controlled. After this pre-purge is competed, spark ignition is provided at the burner.
