DESCRIPTION

INSTALLATION INSTRUCTIONS

The 50A65-5165 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 incorporates 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:
