Sequence of Operation
Starting Circuit: Upon a call for heat, the fan is energized. Once operational static pressure is achieved,
the differential switch will close initialing the ignition sequnce. After a 5-second delay, the glo-bar is
energized for 45 seconds and the control allows the gas valve to open.
The trial for ignition is 8 seconds. If flame sense is not established within 8.5 seconds, the heater will
attempt two (2) additional ignition sequences before proceeding to soft lockout. Soft lockout automatically
retires after one (1) hour or the control can be reset by briefly interrupting the power source.
Running Circuit: After ignition, the flame rod monitors burner flame. If sense of flame is lost, the control
closes the gas valve within one second and a new trial sequence (identical to the starting sequence) is
initiated. If flame sense is not established within 8.5 seconds, the heater will attempt two (2) additional
ignition sequences before proceeding to soft lockout. The control can be reset by briefly interrupting the
power source.
This heater must be installed and serviced by trained gas installation and service
personnel only.
Do not bypass any safety features or the heater’s built in safety mechanisms will be
compromised.
