CPSC campaign 05274
Hazard
Screws on some water heater valves could break. If this happens, gas could leak from the valve, which poses a risk of gas explosion and fire.
Remedy
Consumers that believe they may have an affected water heater, please click on http://www.icca.invensys.com/robertshaw/recallarchive.htm. Have the model and serial numbers of your water heater ready. For further assistance, please contact Robertshaw. The model and serial numbers can be found on the manufacturer's label on the water heater. Robertshaw will arrange for a free repair or replacement, if necessary. If you smell gas near the appliance or in the building, immediately leave the area and call your gas company or a certified gas technician to investigate the cause.
