Questions and answers
Heater only gets to105 temp
On my Girard tankless water heater, there are no error codes, the UPC power switch comes on, the temperature display comes on, the flow sensor has been replaced, the GPM is correct, the voltage on the flow sensor is correct, But the gas, shower, and **** symbols do not come on. What could be the issue keeping it from working properly?
If the gas, shower, and other symbols do not come on despite the power switch, temperature display, and flow sensor being functional, the issue could be due to one of the following reasons:
1. Insufficient Water Flow – The unit requires a minimum water flow of 0.70 GPM (+/- 10%) to operate. If the flow is too low, the heater will not activate.
2. Gas Supply Issue – Ensure the LP gas supply is turned on, and there are no restrictions or blockages in the gas line.
3. Flame Detection Failure – If the burner does not ignite or the flame sensor does not detect a flame, the system will not proceed with operation.
4. Electrical Power Issue – The heater requires a stable 12VDC power supply. If the voltage drops below 10VDC, the unit will not function.
5. Faulty Components – A malfunction in the gas valve, blower, or electronic control system could prevent normal operation.
Checking these factors should help identify and resolve the issue.

the heater stops heating water while in shower, then will start up again, what is causing this to occur? This is my first time using a tankless system. Thank you
