LED STATUS
0 FLASHES (LED NOT LIT)
RED LIGHT ON (SOLID)
PROBLEM
Pilot light is not lit or Thermopite
has not yet reached normal
operating temperature.
Pilot light was recently extinguished
and the Thermopile is cooling
down.
1 FLASH (EVERY 3 SECONDS) Normal operation.
2 FLASHES Pilot is tit but the Thermopite is
not producing the required output
voltage.
CORRECTIVE ACTION
Turn Gas Control Valve/Thermostat knob to OFF.
Wait 10 minutes, then attempt to relight Pilot by
following the lighting instructions on the water
heater's label. Until the Thermopite reaches its
normal operating temperature, the Status Light wilt
not blink, even if the Pilot is tit. It may take up to 90
seconds of continuous Pilot operation before the
Thermopite reaches normal operating temperature
and the Status Light starts to blink.
If the Status Light does not blink after three lighting
attempts, check to make sure unit is getting gas.
Remove the outer door. Press reset button. Replace
outer door. Turn Gas Control Valve/Thermostat
knob to OFF. Wait 10 minutes, then attempt to light
Pilot by following the lighting instructions on the
water heater's label. Look through the sight glass
for the Pilot flame. If Pilot is not visible, the spark
igniter or gas supply to the Pilot should be checked.
If the Pilot is visible and the Status Light does not
blink after 90 seconds of continuous Pilot operation,
the Pilot flame may not be heating the Thermopile
sufficiently (weak Pilot) or the Thermopite may be
defective, or wiring connectors may be loose.
Replace outer door and verify proper operation after
servicing
NOTE: If the water heater has been operating
but has stopped and will not re-light, check the
flame-arrestor for signs of high temperature (blue
or black) discoloration indicating a flammable
vapor incident. If you suspect a flammable vapor
incident has occurred, do not use this appliance.
Immediately call a qualified technician to inspect the
appliance. Water heaters subjected to a flammable
vapors ignition wilt require replacement of the entire
water heater. NOTE: Check the gas control valve/
thermostat and thermal switch for any loose wiring
connections, correct immediately.
Turn Gas Control Valve/Thermostat knob to OFF.
Wait 10 minutes for the Thermopite to cool, then
attempt to relight Pilot by following the lighting
instructions on the water heater's label. NOTE: This
gas control valve/thermostat has built-in circuitry
that requires waiting 10 minutes between lighting
attempts. Until the Thermopile reaches its normal
operating temperature, the Status Light wilt not
blink, even if the Pilot is tit. It may take up to 90
seconds of continuous Pilot operation before the
Thermopite reaches normal operating temperature
and the Status Light starts to blink.
No corrective action necessary.
Turn Gas Control Valve/Thermostat knob to OFF.
The Thermopite is probably defective, but loose
wiring connections or a weak Pilot flame can also
cause this symptom.
