DESCRIPTION
INSTALLATION INSTRUCTIONS
The 50A55-3797 is an automatic gas interrupted
ignition control that employs a microprocessor to
continually monitor, analyze, and control the proper
operation of the gas burner, inducer, and fan.
Signals interpreted during continual surveillance of
the thermostat and flame sensing element initiate
automatic ignition of the burner, sensing of the flame,
and system shut-off during normal operation.
These controls incorporate system fault analysis for
quick gas flow shut-off, coupled with automatic ignition
retry upon sensing a fault correction. It is designed as a
replacement for the following controls:
