CPSC, Firms Announce Recall of GSW Water Heaters With S.I.T. Temperature Controls

When installing a GSW water heater with a SIT AC4 gas control valve in the identified group, or re-lighting the pilot light, the following instructions must be complied with: 1 - Make sure that the water heater contains cool water prior to lighting the pilot by opening a hot water faucet near your water heater and allowing the water to run for five minutes. Close the faucet. 2 - Turn the gas/temperature control knob clockwise to the maximum (VERY HOT) setting, and then slowly turn the knob back counterclockwise to the PILOT position, indicated by the yellow button. Listen for the main valve to close- this would be a popping or snapping sound. This sound is different from the clicking sound that the knob makes as you turn it. 3 - If you hear the popping sound then the valve is working properly. You should then read and follow the "Installation and Operating Instructions". If you do not hear the popping sound then do not attempt to light the pilot and replace the valve. 4 - If the unit has been stored or is being installed in a cold environment and the main valve does not close before the knob is turned back to the PILOT position, the gas control valve must be warmed up to a temperature above 32 degrees F or 0 degrees C. Once warmed up, repeat the procedure above. If the gas control valve does not close (popping sound), replace the valve. If the water is too hot or if the temperature and pressure valve opens, turn down the temperature using the temperature control. If the water remains too hot or the temperature and pressure relief valve continues to open, then replace the valve.
