Verify pressure tap between gas valve and blower inlet. Turn to Page 19 and verify that the gas regulator setting is 0.2” (0.5cm) wc below the blower inlet pressure. Replace gas orifice with smaller size. Flame is “fluttery.” Exhaust may have acrid smell or burner may fail to stay lit. Flame is too lean. Turn to Page 19 and verify that the gas regulator setting is 0.2” (0.5cm) wc below the blower inlet pressure. Replace gas orifice with larger size. Burner pulsates or surges, especially on ignition. Exhaust vent is too long. Reduce length of exhaust vent and/or number of elbows. Combustion appears normal, but flame does not stay lit. Flame current is not being sensed. Check for wet or damaged igniter with low resistance to ground. Replace with new igniter. Verify burner flameholder is properly grounded. Replace Ignition Control Module. Heat Exchanger Troubleshooting SYMPTOM CAUSE REMEDY Boiling in heat exchanger. May be accompanied by “bumping” sounds. Low water flow to heater. Heat exchanger plugged. Bypass valve stuck open. Thermal governor stuck closed. Service pump and or filter. Service heat exchanger. Correct water chemistry. Service bypass valve. Replace thermal governor. Sweating. Thermal governor failed. Replace thermal governor. 30 31 4 PRESS TAB VENT PILOT OFFOFF ONON 2737 0197 1 3 4 5 6 7 8 10 9 2 12 11 For complete Electrical System parts breakdown (Key Nos. 1 through 4), See Page 34 For complete Burner System parts breakdown (Key Nos. 5 through 9), See Pages 31 and 32 For complete Water System parts breakdown (Key Nos. 10 through 12), See Page 33 Repair Parts are available from your Sta-Rite dealer.
