Lochinvar water heater shows E014; burner may shut down unexpectedly.

Critical safety: Gas components must be handled with extreme care. Turn off gas at the manual shutoff and disconnect power. If you smell gas, evacuate and contact your gas supplier or fire department.

Steps:

• 1. Inspect wiring: Check the gas valve connector and wiring harness for secure connections and heat damage.
• 2. Verify gas supply: Confirm the manual gas valve is open and that other gas appliances operate normally.
• 3. Professional pressure test: Have a qualified technician measure inlet and manifold gas pressures while the unit attempts to fire, comparing to Lochinvar specifications.
• 4. Replace gas valve if needed: If the valve does not open when energized or fails leak tests, replace it with the exact Lochinvar gas valve assembly and perform leak checks with approved leak detection solution.
