Description: This recall involves GSW water heaters with S.I.T. model 650
AC4 gas/temperature controls. The temperature control knobs on GSW propane
water heaters are red and the control knobs on GSW natural gas water heaters
are blue. The controls can be found on GSW Water Heaters with serial numbers
ranging from 0202694162 to 0304507825.
Sold at: Regional appliance distributors from February 2002 through April
2003 for between $150 and $550.
Manufactured in: The gas temperature controls were manufactured in Mexico.
The water heaters were manufactured in Canada.
Remedy: 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.
