Loss of Flame Signal – The heater will relight 4 times before the control goes into this lockout condition.
- Monitor the gas pressure to the unit while in operation.
- Assure that the flame is stable when lit.
- Check to see if the green light on the display module is out while the heater is running.
- If the green light doesn’t come on or goes off during operation check the flame signal on the status menu.
- If the signal reads less than 1 microampere, clean the flame rectifier probe.
- If the flame rectifier probe continues to read low, replace it.
