RESETTING THE HEATER CONNTROL
• Soft lockouts as diagnosed by the system error codes require the gas control to be
reset.
• To reset the control, slide the “ON/OFF” switch to the “OFF” position. Wait fot 10
seconds and move the switch back to the “ON” position.
• If the problem that caused the control to lock out has not been corrected, the
control will remain or again go back into lockout.
LOCKOUTS
Soft Lockout
• Occurs when a system safety device trips to break the sequence of operation, The
control will retry the system in a timed basis but will not reinstate operation until
the failure is corrected.
Hard Lockout
• Occurs when the main controller fails and must be replaced.
The gas control valve includes a temperature limiting ECO (Energy Cut Off) system
that will shut off the water heater if the water temperature is too high.
Should the water temperature get too high, the diagnostic status light will indicate a
code (4 flashes), indicating an over-temperature condition and the main burner will be
shut off. If a high temperature condition occurs, turn the main gas supply OFF and have
the water heater repaired by a qualified service technician. Contact your local dealer
for service information.
Note: Should an over-temperature condition occur, restart the water heater and verify
the LED flash sequence. If the 4 flash sequence is observed, slide the “ON/OFF” switch
to the “OFF” position. Turn Main Gas Supply “OFF”. Replace the gas control valve.
