How to Fix / Troubleshooting
Safety First: Turn off gas and power. Gas pressure testing must be done by a licensed gas technician.
- Check other gas appliances: Note whether other gas appliances lose flame or performance when the heater runs. This can indicate supply issues.
- Inspect gas shutoff valves: Ensure all manual gas valves to the heater are fully open.
- Have gas pressure tested: A professional should measure static and dynamic gas pressure at the heater inlet and compare to Rheem requirements. If pressure is low, the gas line or regulator may need upgrading.
- Clean inlet screen (pro): Some gas valves have an inlet screen that can clog. A technician can remove and clean this screen if accessible.
